Scientists Suggest Total Solar Eclipse May Prompt Dawn Behavior in Birds

On April 8, 2024, a total solar eclipse interrupted the daylight cycles of North American birds as they prepared for spring breeding. Researchers at Indiana University, after analyzing over 10,000 community observations and utilizing artificial intelligence to examine nearly 100,000 bird calls, discovered that bird behavior was significantly impacted by the few minutes of unexpected afternoon darkness. More than half of the bird species altered their biological rhythms, leading many to produce dawn choruses in the aftermath of the eclipse.

The daily and seasonal rhythms of birds are closely regulated by variations in light and darkness.

What occurs when these cycles are abruptly disrupted, such as during a total solar eclipse?

Previous research has explored the effects of solar eclipses on animal behavior, yet many studies have only provided scattered or anecdotal insights regarding animal responses.

Indiana University researcher Liz Aguilar and her team viewed the total solar eclipse in April 2024 as a unique research opportunity, offering an unprecedented natural experiment to observe how birds react to sudden light changes.

In preparation for the solar eclipse that would cast nearly four minutes of darkness over large regions of the central and eastern United States, they developed a smartphone app called SolarBird, which allows users to document bird behaviors in real time during the eclipse.

The citizen scientists’ contributions resulted in almost 10,000 observations spanning 5,000 km along the eclipse’s path.

Simultaneously, researchers deployed autonomous recording devices across southern Indiana to capture the calls of about 100,000 birds before, during, and after the totality.

These recordings were analyzed using BirdNet, an AI system capable of identifying species calls and measuring vocal activity.

Findings revealed that 29 out of 52 species detected exhibited significant changes in their singing behavior at various points during the event, although the eclipse’s effects varied among species.

In the moments leading up to the eclipse, 11 species were found to sing more than usual as darkness approached.

During the four minutes of darkness, 12 species reacted—some becoming silent, while others increased their vocal activity.

The most notable responses were observed after the sun re-emerged, with 19 species adjusting their songs to mimic a false dawn chorus.

Notably, barred owls hooted four times more frequently than usual, while robins—renowned for their pre-dawn melodies—hooted six times more than normal.

“These patterns indicate that the solar eclipse temporarily reset the internal clocks of certain birds, causing them to act as if a new day had commenced,” the researchers stated.

Their paper was published in the October 9, 2025 edition of the journal Science.

Proba-3: Stunning Image Captures the First Artificial Solar Eclipse

Here’s a rewritten version of your content while keeping the HTML tags intact:

The sun’s corona appears as it would to the human eye during a solar eclipse, but through a green filter.

ESA/proba-3/aspiics

The synchronized movement of the twin satellites has produced the first artificial solar eclipse in space, revealing the burnt corona of the sun in remarkable detail.

The ProBA-3 mission, launched last December, is operated by the European Space Agency (ESA) and consists of two satellites positioned 150 meters apart.

One of the satellites, known as Occulter, features 1.4-meter wide discs made from carbon fiber and plastic, effectively blocking sunlight coming from the second satellite, Coronagraph. The alignment accuracy of the satellites is within one millimeter for capturing images.

In March, the satellites autonomously synchronized for extended periods, providing lengthy exposures of the solar eclipse. ESA scientists can stitch these exposures together to generate a comprehensive image of the solar corona, the outermost layer of the sun’s atmosphere.

“When I first viewed these images, it was unbelievable,” says Damien Galano from ESA. “But shortly after, it transformed into an incredible sense of achievement and pride for all our hard work.”

The image above captures the visible light of the corona, resembling how it would appear to the human eye but through a green filter.

This image illustrates the light emitted from electron-depleted iron in the most heated sections of the corona.

ESA/proba-3/aspiics

The Proba-3 satellite camera also captures light frequencies linked to specific elements within the solar corona, exemplified by the dark green image above.

“We can clearly see the substantial achievements made during COVID,” remarks Galano.

ESA/proba-3/aspiics

The image above illustrates the sun’s corona, artificially colored purple in polarized white light. This technique allows scientists to distinguish the polarized light from the hot corona from that scattered by interplanetary dust.

These images were primarily captured to verify the ProBA-3 mission’s functionality. When fully operational, they will take pictures of the artificial food every 19.6 hours.

This will enhance our comprehension of solar corona physics, and according to Galano, it will also improve understanding of solar winds and coronal mass ejections that influence space weather.

Where and How to View the Partial Solar Eclipse in March 2025

There is currently another solar eclipse happening.

On Saturday, the moon will cast a shadow on the earth’s surface, creating a partial solar eclipse visible to some in the US, Canada, the Caribbean, Europe, Russia, and Africa. While not as spectacular as last year’s total solar eclipse in the US, it still offers a chance to pause from daily concerns and observe our position in the solar system.

During a solar eclipse, the moon appears to take a bite out of the sun, but the amount of coverage varies depending on the location. It’s important to note that cloud cover can obstruct visibility.

It’s never safe to view a partial solar eclipse without proper eye protection, as the sun’s surface will still be visible during the event.

The experience of a partial solar eclipse can differ based on location, with the extent of sun coverage and overall visibility varying. It’s also advisable to check local weather conditions for clear viewing.

NASA has released a schedule of solar eclipse times in various major cities here.

In North America, the eclipse begins early in the morning, with the sun mostly partially covered when it rises.

The upcoming solar eclipse will be visible in the northern hemisphere, spanning both sides of the Atlantic. Unlike a total solar eclipse, it covers a larger area of the sun with fewer defined paths.

Viewers along the northeast coast of the US will witness the most significant coverage of the sun during the eclipse. For instance, individuals in Boston may see 43% of the sun covered at 6:38am, while New York City will experience a 22% coverage. Further south, in Washington, D.C., there will be a minimal 1% coverage at 6:59am.

The most substantial sun coverage will occur further north, with areas like northern Quebec, Nunavut, and parts of Newfoundland and Labrador in Canada seeing over 90% of the sun covered by the moon.

Across the Atlantic, residents of Northern and Western Europe, as well as the northwest coast of Africa, will experience the solar eclipse in the late night or early afternoon. In northern Russia, the eclipse will occur in the late afternoon and in some locations close to sunset.

Eclipse duration can vary, with places like Halifax, Nova Scotia experiencing an eclipse lasting over an hour while Buffalo, with just a 2% coverage, will have a shorter duration of seven minutes.

A partial solar eclipse occurs when the moon moves between the Earth and the Sun, partially obscuring the sun from view.

Unlike a total solar eclipse where the sun is entirely covered, during a partial eclipse, only a portion of the sun is obscured. This occurs when the Earth, Moon, and Sun are not perfectly aligned. As a result, the sky does not darken enough during a partial eclipse to reveal stars and planets, and animals are unlikely to exhibit strong reactions.

A solar eclipse typically happens in pairs, two weeks apart, representing the time it takes for the moon to travel to the other side of the globe. Recently, stargazers witnessed a red moon during a full lunar eclipse earlier this month.

Staring at the sun, even for a few seconds, can lead to permanent eye damage as the retina lacks pain receptors. The same risk applies during partial solar eclipses. However, there are ways to protect your eyes while observing the event, such as using proper eye protection like eclipse glasses.

Be cautious of counterfeit solar eclipse glasses and viewers. To ensure safety, refer to a list of trusted suppliers compiled by the American Astronomical Association here.

If you’re unable to find eclipse glasses in time, there are alternative safe viewing methods, such as projecting the eclipse onto the ground using household items like cardboard or a kitchen strainer. The next partial solar eclipse is set to occur on September 21st, primarily visible in Australia, while a total solar eclipse is expected in the summer of 2026.

In addition to future solar eclipses, there are upcoming total lunar eclipses scheduled for September and March of next year, offering different celestial viewing experiences.

Next Solar Eclipse: How to Watch the 2025 Partial Eclipse

Another solar eclipse is above us.

On Saturday, the moon casts a shadow on the surface of the earth. This is a phenomenon in which some people in the US, Canada, the Caribbean, Europe, Russia and Africa can experience it as a partial solar eclipse. As impressive as the total solar eclipse that crossed the US last year, but it’s an opportunity to take a break from secular issues and witness our place in the solar system.

During a solar eclipse, the moon appears to bite from the sun, but how much does it change depending on the location? And clouds can ruin your vision.

It is never safe to see a partial solar eclipse without protective eye gear, as the surface of the sun will not be completely obscured during this event.

People in areas where partial solar eclipses can experience it differently. How much sun is covered and what happens depends on where. You should also check your local weather report for clear or cloudy conditions.

NASA has published a list of solar eclipse times in several major cities here.

In North America, events begin early in the morning of sunrise, and are mostly already partially covered when the sun appears.

Saturday’s solar eclipse will be seen in the northern hemisphere, including both sides of the Atlantic. Unlike a total solar eclipse, it affects the wide area of the sun and has few clear paths.

In the US, viewers along the northeast coast will see the biggest solar eclipse. For example, people in Boston can see 43% of the surface of the sun covered at 6:38am in the eastern part. In New York City, the sun is eclipsed at just 22%, and those who are on the same south as Washington, D.C. at 6:46am experience a 1% solar eclipse at 6:59am.

The most blocked sun occurs much north. People in northern Quebec, Nunavut, and many of Newfoundland and Labradors in Canada witness more than 90% of the moon-covered sun.

On the other side of the Atlantic, people in Northern and Western Europe, and on the northwest coast of Africa, solar eclipses reach maximums in the late night or early afternoon. In northern Russia, solar eclipses occur late in the afternoon and in several places near sunset.

Eclipses can last for more than an hour in places like Halifax, Nova Scotia. The moon slowly glides over 83% of the sun, reaching its maximum point and retreat. However, in Buffalo, where the solar eclipse reaches up to 2%, it lasts just seven minutes.

The solar eclipse occurs when the moon glides between the Earth and the Sun, protecting all or part of the surface of the Sun from our field of vision.

The most dramatic version of this is the solar eclipse of the total sun when the entire sun is covered and its outer atmosphere, or when the corona is visible for a few minutes at the height of the event. This is known as the whole.

In contrast, on Saturday, only the mass of the sun is obscured, known as the partial solar eclipse. This happens when the Earth, Moon and Sun are incompletely aligned. Unlike the whole, the sky does not get dark enough during the partial solar eclipse to see stars and planets during the day. Animals are not likely to respond strongly.

The solar eclipse comes in pairs two weeks apart. It is the amount of time it takes for the moon to sway on the other side of the globe. The Stargazers recently saw the moon turn red and red during a full lunar eclipse earlier this month.

Even in seconds, staring at the sun can permanently damage your eyes. The retina has no pain receptors so you don’t feel it while it’s happening.

The same applies during partial solar eclipses. However, there are several ways to protect your eyes and still watch the event. If you save your paper glasses from gross solar power last year, they can be used again, provided they are not torn, scratched or damaged.

Beware of counterfeit solar eclipse glasses and solar viewers. You can find a list of trusted suppliers compiled by the American Astronomical Association here.

If it’s too late to find Eclipse Glasses, you can safely view the projection onto the ground using items around the house. Options include fashioning Eclipse Viewer from CardStock or cardboard boxes. You can also use a kitchen strainer, straw hat, or even your own fingers.

Another partial solar eclipse occurs on September 21st, the most common in Australia, according to NASA. A total solar eclipse occurs in the summer of 2026, which is visible on the top of the Northern Hemisphere.

If it’s too long and the wait is too long, then the two total lunar eclipses are also coming. One will be in September and the other will be in March next year. Unlike the total solar eclipse of the total sun only visible along the narrow path of the Earth’s surface, total erythema can be seen by most people on the night of the planet.

The Solar Eclipse of 2025: A Guide to Witnessing This Year’s Celestial Phenomenon

Skywatchers in the northeastern United States, eastern Canada, and parts of Europe are eagerly anticipating a rare astronomical event this spring. On the morning of Saturday, March 29th, 2025, a partial solar eclipse will grace the sky, coinciding with a spectacular “double sunrise.”

Here is all you need to know about the partial solar eclipse, including where to watch, what to expect, and how to safely observe it.

When is the Partial Solar Eclipse in 2025?

The first and only solar eclipse of 2025 will occur on March 29th, starting at 8:50am GMT (4:50am EDT) and ending at 12:43 PM GMT (8:43am EDT). The maximum solar eclipse will take place at 10:47 AM GMT (6:47AM EDT).

In the US, the solar eclipse will begin at 6:13 AM EDT and end at 7:17am EDT, with the exact times varying based on location. The most dramatic views and longest duration of the eclipse, with 85% of the sun obscured, will be experienced in some areas.

In England, the solar eclipse will begin in London at 9:56am GMT, reach its peak at 11:03 AM, and end at 12:00 PM GMT. The extent of the eclipse may vary slightly depending on location, with Scotland witnessing over 40% obscuration in cities like Glasgow.

Where to Watch the Partial Solar Eclipse?

This partial solar eclipse will be visible across a wide area of the Northern Hemisphere, including the Northeastern United States, Eastern Canada, most of Europe, and northwest Africa.

Fourteen US states, including Washington DC, will witness a partial solar eclipse, with Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, Vermont, Virginia, and West Virginia among them.

The point of greatest obscuration will occur in Nunavique, Quebec, where 94% of the sun will be hidden at the peak of the solar eclipse.

What is a Partial Solar Eclipse?

A partial solar eclipse occurs when the moon passes between the Earth and the Sun but does not fully block the Sun. Instead, it covers only a portion of the solar disk, creating the appearance of the moon taking a bite out of the sun.

This results in a deep but incomplete solar eclipse, with the sun taking on a crescent shape. Unlike a total solar eclipse, where the sky goes completely dark, daylight remains during a partial solar eclipse, albeit with a dim and eerie quality.

What is a Double Sunrise?

“Double Sunrise” is a rare and stunning visual effect that can occur when a solar eclipse coincides with the rising sun.

From parts of eastern Canada and northeastern United States, the sun may appear as a crescent on the horizon during a partial solar eclipse. The tip of the crescent moon, often called the “devil’s horn,” may also be visible, giving the illusion of two separate sunrises.

Maine and parts of Quebec, Canada, offer the best chance to witness this phenomenon.

After the double sunrise, the sun will continue to rise as a thin arc in the sky.

How to Safely Watch a Partial Solar Eclipse

Unlike a total solar eclipse, partial solar eclipses should never be viewed directly with the naked eye, even when most of the sun is covered. Even small slivers of the sun can cause permanent eye damage.

If possible, obtain eclipse glasses that are certified to ISO 12312-2 international safety standards.

Crowds gather around Bryant Park in New York City, wearing eclipse glasses to witness a partial solar eclipse on April 8, 2024.

If using binoculars, cameras, or telescopes, ensure they are equipped with a solar filter on the front end (not the eyepiece).

If you are unable to find glasses or filters, indirect viewing methods are still possible. By creating a small hole (1-2mm) in a card, you can project sunlight onto a flat surface to observe the solar eclipse safely.

Weather plays a significant role in eclipse visibility. A clear sky offers the best viewing conditions, but even in cloudy weather, you may still experience a dimming effect as the moon passes in front of the sun.

How to Watch the Solar Eclipse 2025 Online

If you are unable to witness the partial solar eclipse in person, don’t worry. You can watch it online. The Royal Observatory Greenwich in the UK will be live streaming the event starting at 10am GMT.

Tonight, a total lunar eclipse will be visible across the United States.

A total lunar eclipse will be visible across the United States on Thursday night or early Friday morning.

The lunar eclipse will begin around midnight ET when the Earth’s shadow completely covers the moon – and will last for over an hour from 2:26 am to 3:32 am. According to Earth Sky. The complete process will continue until around 6 am ET.

The lunar eclipse will be visible in most of North and South America, as well as in Africa, Europe, eastern Australia, Russia, and half of Japan.

During a total lunar eclipse, the sun, earth, and moon align, creating shadows on the moon. As a result, the moon appears to have a reddish tint, earning it the nickname “Blood Moon.”

This reddish tint is caused by the way sunlight passes through the Earth’s atmosphere. Shorter wavelengths of blue light are easily scattered, while longer wavelengths of red light are more likely to pass through, giving the moon its distinctive color.

Unlike solar eclipses, all stages of a lunar eclipse can be safely viewed with the naked eye, although binoculars and telescopes can enhance the experience.

Unfortunately, cloudy conditions are predicted for many skywatchers tonight. Those who miss this event can look forward to the next lunar eclipse on September 7th, followed by another on March 3rd, 2026.

Overall, total lunar eclipses are less common than partial solar eclipses, which can occur up to three times a year. Neither of the two lunar eclipses in 2024 were total, with the last total lunar eclipse occurring in 2022.

Proba-3: Twin spacecraft launched to create a simulated solar eclipse

Two Proba-3 spacecraft work together to create an artificial solar eclipse

ESA

The European Space Agency (ESA) aims to create an artificial solar eclipse in space with its upcoming Proba-3 mission, which will help study the Sun and demonstrate extremely precise formation flight down to just a millimeter. It turns out.

Scheduled to launch on December 4 on an Indian PSLV-XL rocket, the mission will consist of two spacecraft. After launch, they will be placed into a highly elliptical orbit around the Earth, bringing them about 600 kilometers (600 kilometers) close to Earth, but at a distance of about 60,000 kilometers (60,000 kilometers) from the Earth.

One of the spacecraft, called Occulter, features a 1.4-meter-wide disc made of carbon fiber and plastic. The other spacecraft will fly about 150 meters behind the first spacecraft and point its camera there. From this vantage point, the occulter's disk blocks the surface of the Sun, much like the Moon appears to cover the Sun during a total solar eclipse. This will allow imaging probes to observe the solar corona, or the sun's atmosphere, in more detail than ever before.

“This will be the closest we've ever seen the corona to the Sun in visible light,” said Damien Galano, ESA's Proba-3 mission manager. “This could provide concrete information about the temperature of the corona, the formation of the solar wind, and how the corona expands into space.”

Proba-3 accomplishes this feat by flying with incredible precision. Both spacecraft are equipped with sensors to track their position in space, and the Occulter uses 12 nitrogen thrusters to autonomously maintain its position with its partner with millimeter accuracy. The thrusters can deliver just 10 millinewtons of thrust, which is 1/50th the force of human breathing.

To limit the destabilizing effects of Earth's gravity, the artificial eclipse will last six hours when the spacecraft is furthest from Earth. More than 1,000 solar eclipses are planned during the two-year mission. Galano said this is the first time since experiments with artificial solar eclipses in space. 1975 Apollo-Soyuz Test Project.

The experience gained from the Proba-3 mission could also be applied to things like refueling spacecraft and developing large telescopes in space. “Until now, we've only been able to achieve accuracy of a centimeter or better,” said Steve Buckley, Proba-3 lead engineer at Onsemi, a US company that developed some of the sensors for the mission. “This is 10 times better.”

2024 Solar Eclipse Live: Watch NASA’s broadcast of the total eclipse – New Updates

On April 8th, a total solar eclipse will occur in Mexico, the United States, and Canada. This type of solar eclipse only occurs when the sun and moon line up perfectly in the sky, causing the moon to cover the entire disk of the sun and cast a shadow on Earth. The path this shadow follows as it crosses the ground at speeds exceeding 2,400 kilometers per hour is called a total path, and during this eclipse, the shadow will cross from the west coast of Mexico, across 13 states of the United States, to Ontario, Quebec, Newfoundland, and beyond. At any given location, totality lasts from about 90 seconds to nearly 4.5 minutes.

During this period, the sky becomes dark as at dusk and the temperature drops by 10 degrees. Viewers will be able to remove their eclipse glasses, which are essential during the partial phase of the eclipse, and look directly at the Sun, which is covered by the Moon. At this range, the sun’s outermost layer, the corona, becomes visible. At other times, it may be too dark to see due to the glare of the sun. Total solar eclipses like this one are rare opportunities for researchers studying the sun and have led to major scientific advances over the years.

Where and When Can You View a Total Solar Eclipse?

One of the most eagerly anticipated sky-watching events in recent years is set to take place on Monday, with a total solar eclipse gracing North American skies.

Weather permitting, millions of people in Mexico, 15 U.S. states, and eastern Canada will have the opportunity to witness the moon passing between Earth and the sun, momentarily blocking the sun’s light.

The total solar eclipse will be visible along a “total path” that spans more than 100 miles wide and extends across the continent, with the moon completely obstructing the sun, casting darkness over the afternoon sky for a few minutes.

The rest of the continental United States will experience a partial solar eclipse, where the moon will appear to take a bite out of the sun, with the size of the “bite” varying by location.

The first total eclipse event in North America on Monday will occur on the Pacific coast of Mexico at around 11:07 a.m. Pacific time, as per NASA.

Moving northeast through Mexico, the eclipse’s path will cross through states such as Texas, Oklahoma, Arkansas, Missouri, and beyond, leading into parts of Canada including southern Ontario and Quebec.

The duration and timing of the total solar eclipse will vary depending on location, with most areas experiencing about two minutes of darkness, with the longest period usually occurring at the center of the eclipse’s path.

This year, the longest totality period will last 4 minutes and 28 seconds in the northwest region of Torreon, Mexico.

Strange Animal Behavior to Watch for During April’s Solar Eclipse

On April 8th, while most people in the United States will be staring into the sky (preferably wearing appropriate safety glasses), animals will have no idea what’s going on.

That’s natural, right? For animals, the sun constitutes their entire life. Without energy drinks and late-night TV to disrupt their sleep schedules, the sun is an all-in-one alarm clock, sleeping pill, and calendar for animals.

In 2017, a team of researchers studied how different animals responded to a total solar eclipse in the United States.

“Basically, everything we’ve ever heard about animal behavior during a solar eclipse can reasonably be considered anecdotal from a scientific perspective.” Professor Adam Hartstone Rose says the person who led the research. BBC Science Focus.


undefined


Hartstone-Rose and his team observed the behavior of 17 species at Riverbanks Zoo in Columbia, South Carolina. This is the first time such a study has been conducted. What did they find? Now, how animals behave during a total solar eclipse varies dramatically, from not at all bothersome to downright weird…

Strange ways animals may react to solar eclipses

Heartstone-Rose said animals responded to celestial events in one of four ways. These include not responding at all, starting nighttime routines, showing anxiety, and exhibiting new behaviors.

“Most animals fall into a category that we call related to circadian rhythms. So basically, animals treat solar eclipses as if they were evening, then night, then morning; “I get into a routine,” he says.

Similar nighttime routines have been widely reported for other eclipses. As the moon passes in front of the sun, expect birds to quiet down and crickets and cicadas to become more active.

The next largest behavioral category was, somewhat sadly, anxiety-related behaviors. For example, evidence gathered by Hartstone-Rose and her research team suggests that if you’re near a giraffe during a solar eclipse, you should stay well away from them.

“During the peak of the eclipse, the giraffes started running around like crazy and in potentially dangerous ways,” Hartstone-Rose explains.

“Giraffes in the wild are very gentle animals. They’re a little bit wild and sensitive. They don’t do crazy things unless they have to, so when I saw giraffes running around…, only when startled by a predator, vehicle, etc.”

Thankfully, any disturbing behavior didn’t last long. “The good news is that all of the animal’s behavior returns to normal very quickly, literally within minutes.”

But what about these so-called “novel” behaviors? This is where things get weird.

The siamang is a type of gibbon that lives in the forests of Indonesia, Malaysia, and Thailand. Although they look cute, they are known to be very noisy and have large throat pouches.use their heads to help sing.

The research team recorded the calls of the siamang during and for several days before and after the eclipse, and found that it emitted a unique call during the totality. It was something they had never heard before.

“We were able to statistically show that vocalizations during a solar eclipse are much different than at any other time we’ve been able to record vocalizations,” Hartstone-Rose says. “That was pretty remarkable.”

The prize for the strangest solar eclipse behavior is… giant tortoise?

If anxious runs and strange songs weren’t enough, Riverbanks Zoo’s Galapagos tortoises took their reaction to the solar eclipse to a different level.

“Galapagos tortoises are not charismatic animals,” Hartstone-Rose says. “They’re like weird looking rocks that can live to be well over 100 years old.”

According to stereotypes, they are not particularly fast moving and the males Weight is over 227 kg making it the largest turtle species on Earth.

When the sun eclipsed the moon in 2017, Galapagos tortoises started doing something unexpected. They literally started breeding right before our eyes. “

Therefore, a solar eclipse may lift your turtle’s mood. Did anyone know?

How can I participate this time?

After 2017’s surprising discoveries, researchers hope to do even more this year.

Hartstone-Rose and a team of researchers plan to observe animal behavior at the Fort Worth Zoo in Texas. They will observe and compare some of the same species and new species from 2017.

But you don’t have to be a trained researcher to help scientists understand animal behavior during this once-in-a-lifetime event.

“The really exciting research we’re doing is solar eclipse safari project” says Heartstone Rose.

If you want to participate, just choose the animal you want to observe, whether it’s a dog, cat, domestic animal, or natural animal.

You don’t have to go down the path of perfection either. There will be at least a partial solar eclipse across the United States on April 8, and researchers want to know whether the severity of the eclipse affects behavior.

Before you worry that you’ll miss the eclipse itself because you’re too busy checking to see if your dog is scratching its ears, don’t worry. Data collection only takes a few seconds every few minutes, so you still have time to understand everything.

Why study animals during a solar eclipse?

While understanding how different animals behave during a solar eclipse may seem interesting to some, it is ultimately a pointless endeavor. Fair point. Although there is some method to madness.

First, Hartstone-Rose points out that it’s important to understand which animals exhibit anxiety.

“If solar eclipses are upsetting, or if the human response to solar eclipses is upsetting, that’s important information for us to know. For example, giraffes really If it runs around, it may be ethical to move the giraffe indoors during the next solar eclipse.

“At the end of the day, we don’t want them to hurt themselves.”

Even more poignantly, he thinks this could answer some of the big questions about our relationship with animals.

“One of the big questions, and anyone who has a pet dog or cat knows this, is what’s going on inside this animal’s head. Do you know? ? What is my dog thinking at any given moment? People have such questions not only about dogs, but about all their favorite animals.”

Perhaps by understanding how animals respond to one of the most unique and fascinating experiences on earth, we can move one step closer to solving the mystery.

5 fun solar eclipse activities for kids

There are plenty of solar eclipse activities to enjoy with your kids

Edwin Remsburg/Alamy

If you’re planning to enjoy the total solar eclipse on April 8 with your kids, here are some things you can do before and during the eclipse to help them understand what causes it and get the most out of the experience. Here are some activities.

1. Build an Eclipse viewer

The day before the solar eclipse, you and your kids can get excited about this big event by creating a solar eclipse viewer. There are several ways to do this. The first method is a simple pinhole camera that uses two pieces of paper. Cut a hole in a piece of paper and cover it with aluminum foil, then cut a small hole in the foil. On the day of the eclipse, when he lifts the paper and shines the sun’s rays through the hole, a version of the eclipse is projected onto his second piece of paper, which he places on the ground.

For a slightly more complicated version, place a piece of paper on one end of a cereal or shoe box and cut two holes in the other end. Place a piece of tin foil over one of the two holes and re-drill it to allow sunlight to pass through. More information on how to create both versions can be found here.

solar eclipse 2024

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

2. Build a solar eclipse model

Another activity you can do before a solar eclipse is to build or act out models of the sun, moon, and earth to understand what a solar eclipse is. All you need to assemble is 3 sticks and his 3 balls to place on the sticks. You can paint and color them to look like the sun, moon, and earth. Make sure the sun is bigger than the moon. You can then show your children what a solar eclipse looks like by placing the sun in the center and moving the earth around the sun and the moon around the earth. A solar eclipse occurs when these three lines line up and the moon moves between the sun and the earth. A lunar eclipse occurs when the moon is on the opposite side of the earth from the sun.

Children can also act out a solar eclipse. Of them, she will give one person a flashlight or flashlight to play the role of the sun and ask them to shine the flashlight on the wall. The other person is the moon, which can move around until it blocks the light of the torch. Both children can play with moving back and forth to show why the distance between the Moon, Earth, and Sun is important when it comes to solar eclipses.

3. Use sunlight to pop balloons

This can be done on any sunny day. But on days when you’re waiting for a total solar eclipse, you can show your kids how to pop balloons using the power of sunlight. This activity requires balloons and a magnifying glass. Inflate the balloon and then hold a magnifying glass over it to magnify the sunlight hitting the balloon. Wait a few minutes and the balloon will eventually pop. Do the same trick by inflating a white balloon inside a black balloon for an even more exciting atmosphere. The black balloon pops, leaving the white balloon inside intact. You can use this to explain how dark surfaces absorb sunlight and light surfaces reflect sunlight.

4. Play with the shadows

On the day of the solar eclipse, a partial solar eclipse phase will last for several hours while we wait for the total solar eclipse. Parents and children can enjoy the solar eclipse by watching and playing with the changes in the shadow. If you have trees nearby, observe the shadows they cast on the ground during the eclipse and you’ll notice that they begin to look like the sun has been bitten. This also works by crossing your fingers and casting a shadow on the ground. Another way to view the eclipse through the shadows is to use a colander or something with small holes. As the eclipse progresses, the shadow begins to take on the shape of the eclipse. You can punch a series of holes in the paper and spell out a word or your child’s name in the shape of a crescent moon.

5. Draw a shadow

This is another activity you can do during the time before and after totality, again making the most of the interesting shadows created by the partially eclipsed Sun. Place a large piece of white paper or sheet on the ground and ask the children to draw the shadows cast by different objects. If you do this at the beginning of the partial phase, and again when everyone is already close, you will be able to see how these shadows change as the eclipse progresses. By now you should have noticed that as the amount of light around you decreases, the shadows become more distinct.

Physicists puzzled by the 1919 total solar eclipse

Total solar eclipse in August 2017 over Jefferson City, Missouri

(NASA/Rami Daoud)

The following is an excerpt from the monthly Launchpad newsletter, where resident space expert Leah Crane travels through the solar system and beyond. You can sign up for Launchpad for free here.

It was in 1919 that the moon did something completely natural and blocked our view of the sun, forever changing our understanding of the universe. Observing from the African island of Principe, astronomer Arthur Eddington observed the positions of stars and planets that became visible in the eerie darkness of the day. Because most of the sun’s light was dimmed, he was able to see how light from distant stars is distorted when it is deflected by the sun’s gravity, an effect called gravitational lensing.

He confirmed his sightings with those of another expedition in Brazil, and these observations provided some of the first evidence for Albert Einstein’s relatively new theory of general relativity. This explanation of how massive objects distort the fabric of space-time is now considered fundamental, but at the time it was a revelation. It changed all the way we think about gravity and the universe.

It also led to my results Favorite newspaper headline most of all time, published in of new york times Later that year, “All the light in the heavens is slanted.” Scientists are more or less puzzled over the observations of solar eclipses. Triumph of Einstein’s theory The stars were determined by where they were visible and by calculation It’s not where it was, but no one needs to worry.”

“No one needs to worry” may seem like a bit of a stretch, but watching a total solar eclipse can certainly make you nervous in ways you can’t explain. I watched it for the first time in 2017. It was truly unforgettable. You might think of a solar eclipse as being like a cloudy day when clouds drift in front of the sun. After all, what’s happening is simply the moon passing in front of the sun and casting a shadow on Earth. But it’s surprisingly different.

The first thing you notice during a total solar eclipse is the moon’s shadow hurtling toward you across the ground at speeds of over 1,500 miles per hour. The extent of the shadow for April’s eclipse will be approximately 185 kilometers, but this can vary slightly based on the exact orientation of the Sun and Moon. As the shadow approaches, it looks like the moon has bitten the sun, and its light has a mysterious, foggy quality.

Suddenly, the area becomes dark. This is wholeness. Temperatures can drop up to 10 degrees. The only light comes from the sun’s outermost layer, called the corona, and ripples beyond the moon’s silhouette. It was completely dark, and some stars were visible in the sky. Many animals, including birds and insects, naturally seem to think it is night, and the otherworldly twilight becomes silent, except for the chirps of awakened nocturnal insects. I can’t tell you how you feel, but for me it was a mixture of awe and some strange primal fear. The sun disappeared, and even though my mind knew why, my body panicked at the loss.

solar eclipse 2024

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

This seems to be a fairly common reaction, not just in humans. Researchers who studied animals during past total solar eclipses found that while some animals simply finished their evening routine early, many showed signs of anxiety and were aimless during total solar eclipses. I discovered that they run and huddle together.

Then, just a few minutes later, the total star will retreat as quickly as it arrived. The shadows rush away, the sun comes out again, and the birds and insects sing again. Astronomers look up from their solar telescopes, dazed but excited by the treasure trove of data they’ve collected.

Humans have been observing solar eclipses for thousands of years, and we’ve learned some very interesting things. When the sun’s disc is covered by the moon, its faint corona becomes visible, making solar eclipses the perfect time to study the sun’s outer reaches. For example, scientists first discovered helium during a total solar eclipse. A solar eclipse is also a great time to observe the plumes of radiation and material emitted from the sun’s surface through the corona. The coronavirus itself is very strange, and there is still much to understand about how it works. Despite being far removed from the sun’s core fusion, the corona is millions of degrees hotter than the sun’s surface, and we still don’t know why.

Even if you haven’t studied the sun’s mysterious layers, it’s worth watching a total solar eclipse. More than 100 years ago, newspaper editors got it right. More or less, you will be confused.

Inmates at a New York Prison to Witness Solar Eclipse

Inmates at New York State’s Woodbourne Correctional Facility will finally have the opportunity to view Monday’s solar eclipse, as announced by lawyers representing the inmates who filed a lawsuit on Thursday.

Six inmates at a medium-security men’s prison in Woodbourne, upstate New York, took legal action against the state Department of Corrections and Community Supervision for not allowing them to witness the eclipse.

The prisoners argued that being denied the chance to see the total solar eclipse was a violation of their religious rights, as they considered it a religious event.

Lawyers involved in the case, Chris McArdle, Sharon Steinerman, and Madeline Byrd from Alston & Byrd, confirmed that the Department of Corrections had agreed to allow the inmates to view the eclipse.

“In response to our lawsuit alleging religious discrimination, the state of New York has entered into a binding settlement agreement allowing six of our clients to view the solar eclipse in accordance with their sincerely held religious beliefs. We are pleased to do so,” they stated in a written release.

After this agreement, the lawsuit filed last week was dismissed. The lawsuit also requested solar eclipse glasses.

Daniel Martucello III, the acting secretary of the department, issued a memorandum on March 11 instructing all facilities to follow a holiday schedule on the day of the eclipse. As per the complaint, the inmates were confined to their cells.

The Department of Corrections mentioned that they had initiated an inquiry into religious requests to view the eclipse, including those from six Woodbourne inmates, even before the lawsuit was filed.

The department stated that they “continued to evaluate and address the matter while the lawsuit was ongoing” and ultimately agreed to allow these six individuals to witness the eclipse.

The lawsuit referenced instances of darkness in religious scriptures such as during the crucifixion of Jesus Christ in Christianity and the eclipse of the sun during significant events in Islam.

On Monday, there will be a visible total solar eclipse in the United States for the first time since August 21, 2017. The next solar eclipse visible in the United States will occur in 2044.

During a total solar eclipse, the sky will darken in the middle of the day.

Ambitious plan to observe the sun during April’s solar eclipse

NASA’s WB-57 research jet will be used to study solar eclipses

Amir Caspi

Solar scientists across North America will study April’s total solar eclipse to observe the sun’s strangest part: the corona.

Although it is briefly visible as a bright halo that appears only when it is total, it is a million times dimmer in visible light than the rest of the Sun. The corona is also a million degrees warmer than the sun’s surface, or photosphere, which only reaches about 6000 degrees Celsius, and extends millions of kilometers into the solar system.

The corona is where the sun’s magnetic field acts on charged particles to form complex shapes called streamers, loops, plumes, etc. Understanding the corona helps us predict the solar wind, the stream of charged particles that is blown into space from the Sun. This is the cause of the aurora borealis, but it’s also a potential threat to astronauts, satellites, and the power grid.

Expectations for the total solar eclipse on April 8th are extremely high. That’s because the total solar eclipse, in which the sun is completely covered, will last up to 4 minutes and 27 seconds, the longest such period on land in more than a decade. We would like to introduce some of the experiments that will be carried out in the future.

solar wind sherpa

Shadia HabalThe solar researcher at the University of Hawaii Institute for Astronomy has been tracking solar eclipses for almost 30 years, using special filters and cameras to measure the temperature of particles from the deepest part of the corona.

Habal’s group, now known as the Solar Wind Sherpas, has traveled to far-flung places, including the Marshall Islands, Kenya, Mongolia, Norway’s Svalbard, Antarctica, and Libya. Habal and her team use filters to image the corona during each solar eclipse, some of which last only a few seconds. By studying the different wavelengths of light emitted by charged iron particles in the corona, temperature can be revealed.

Most often, solar physicists who study the corona rely on space observatory coronagraphs, which use telescope disks to block the sun. But these devices obscure the deepest parts of the corona, towers of plasma called prominences and sources of eruptions called coronal mass ejections.

“Observations during totality are very important,” Habal says. There’s no other way to continuously observe a portion of the Sun’s atmosphere extending from the surface to at least 5 solar radii. “This is fundamental to understanding how the solar atmosphere originates from the Sun and then spreads out into interplanetary space,” she says. Only then will accurate computer models be devised to simulate the corona and help predict space weather.

In the past few years, Habal’s group has made a surprising discovery. The Sun is currently heading towards her solar maximum in 2025, the most active period of his 11-year cycle when solar winds strengthen. Because the corona appears larger during the maximum solar activity during a total solar eclipse, it was thought that there is a close relationship between the solar cycle and the temperature of the corona. But it may not be that simple.

In 2021, Habal and his colleagues published a study based on observations made during 14 total solar eclipses that suggest: The temperature of the corona does not depend on the solar cycle. The lines of the sun’s magnetic field can open and spread outward in the solar wind, or they can close and become hotter, forming a loop. “We found open magnetic field lines everywhere, regardless of the cycle,” Habal says. This means that the temperature of the corona is almost constant.

high flyer

Observations have been impossible since 2019 due to bad weather. “In 2020 there was rain in Chile and in 2021 there were clouds over the Antarctic ocean, but in 2022 there was no solar eclipse,” Habal said.Team members are on an expedition to Antarctica. Benedict Justen Next time, he suggested, they could fly a kite equipped with a spectrometer that separates light into its component wavelengths.

A NASA-funded kite with a wingspan of 6.5 meters was successfully tested in Western Australia during a total solar eclipse in April 2023. It was launched on a kilometer-long tether attached to a vehicle. “It was truly miraculous,” Habal says. Due to bad weather, the team flew for the first time only 45 minutes before the total flight. “It was thrilling.”

This box-shaped kite will fly a NASA-funded scientific instrument to study total solar eclipses.

Clemens Bulman and Benedikt Justen

If the technology works well on future eclipses, more kites will be deployed in the future, and perhaps cameras will be added. “It’s much easier and cheaper than using balloons,” Habal says. But if things don’t work out, there’s always a backup.

During a total solar eclipse, two WB-57 planes will track each other just southwest of the eclipse’s maximum at 740 kilometers per hour, about one-fourth the speed of the moon’s shadow. At this speed, the total velocity increases from 4 minutes and 27 seconds to more than 6 minutes when viewed from the ground. “The WB-57 is perfect for this purpose because the nose cone has a built-in camera and telescope system that allows it to rotate and point at anything no matter what direction the aircraft is flying. ” says Mr. Amir Caspi At the Southwest Research Institute in Boulder, Colorado, he is in charge of the second WB-57 experiment to study the corona in a different way.

Caspi and his team will use a stable platform to image the eclipse using both a visible-light camera and a high-resolution mid-infrared camera developed by NASA. The latter captures light at seven different wavelengths and helps determine which structures in the corona are emitting their own light and which are just scattering light from the Sun’s surface. “To make these observations, we need to be as high up in the atmosphere as possible,” Caspi said. Infrared radiation is difficult to observe from the ground because it is absorbed by the Earth’s atmosphere.

live streamer

Caspi is also part of the Citizen Continental American Telescope Eclipse (CATE) project. The project is an attempt to create a continuous 60-minute high-definition film using a team of 35 citizen scientists who travel a total path from Texas to Maine. They have the same cameras, telescopes, and training, so they can make exactly the same kinds of observations. “Each team will be spaced out so that each station overlaps its neighboring station,” Caspi said. “If one station can’t get data because of clouds or equipment failure, that’s okay.”

He is hopeful the device will work after it was successfully tested in Western Australia last year. “That was the first solar eclipse I ever saw,” Caspi said. He was busy live streaming on his YouTube, so he could only watch a few seconds. “Our devices couldn’t go online, so we spent the whole time holding our phones in front of our faces.”

Creating a Pinhole Solar Eclipse Viewer and Box Solar Eclipse Viewer

To safely observe a solar eclipse, you’ll need some basic equipment

Liansen / Imago / Alamy

If you’re planning on observing the solar eclipse on April 8 this year, whether you’re in the middle of the total solar eclipse or not, you’ll need some gear to fully enjoy it.

The most important rule during a solar eclipse is not to look directly at the sun. This is only possible during totality, a few minutes when the sun’s light is completely blocked by the moon. But for everyone in North America who lives outside the 185-kilometer-wide total orbit, only a partial eclipse will be visible. And for those on the inside of the road, there are still a few hours on either side of totality, but part of the fun is watching the moon slowly move across the sun.

You can use special solar filters, such as eclipse glasses, to look directly at the sun. But you can also view the eclipse using a simple viewer made from a few things you probably have on hand. Here we will introduce how to create two types of Eclipse viewers.

How to make a pinhole camera

All you need for this viewer is paper, aluminum foil, scissors, and a pen. Make a hole in the middle of a piece of paper and cover with foil. Stick the foil in place and use a pen, needle, or other sharp object to make a small hole in the center of the foil. On the day of a solar eclipse, simply hold this up to the sun and place another piece of paper on the ground below. A small bright dot appears on the second sheet of paper. This is a solar projection. As the eclipse progresses and the moon covers more of the sun, you’ll see the shape of the dot change.

How to make a box eclipse viewer

The second type of eclipse viewer works similarly, but the projection is displayed inside a box instead of on the ground. For this, you will need paper, foil, scissors, and a cardboard box. Cereal boxes or shoe boxes work well.

Line one side of the inside of the box with white paper. Then, drill two holes, spaced apart on opposite sides. Tape the foil to one hole and make a small hole in it. The other hole will be a place to look inside.

On the day of the solar eclipse, hold the viewer in front of you with your back to the sun. A projection of the sun should appear on the white paper lined inside the box.

Get Ready for the Ultimate Solar Eclipse Science Experiment!

In April, a total solar eclipse is expected to occur, promising great scientific success thanks to new spacecraft, telescopes, and cosmic coincidences.

The upcoming eclipse will feature the Moon very close to Earth, resulting in a prolonged period of darkness, and an anticipated increase in solar activity with possible dramatic plasma bursts. Additionally, densely populated areas from Mexico to America to Canada will witness this phenomenon.

During the eclipse, citizen scientists among the tens of millions of spectators will assist NASA and other research groups in studying our planet and stars. They will capture images of the sun’s corona as the moon blocks sunlight for up to 4 minutes and 28 seconds on April 8. The atmosphere will witness calm among birds and animals as darkness envelops midday. Other activities include measuring temperature drops, monitoring clouds, and using amateur radio to assess interruptions in communications.

Simultaneously, a rocket carrying scientific instruments will be launched into the ionosphere near the edge of the universe. This launch, from Wallops Island, Virginia, aims to study the electrically charged region of the atmosphere during the partial solar eclipse, obscuring 81% of the sun. NASA’s high-altitude jets will also be deployed with improved telescopes to observe the eclipse’s effects on the sun’s corona and surrounding dust.

Various scientific activities will take place along the eclipse path across different locations. More than 600 weather balloons will be launched for live-streamed atmospheric studies by university students, irrespective of cloudy skies. The eclipse will provide a rare opportunity to observe the sun’s corona, which is usually hidden by its glare, and offer valuable insights into the corona’s extreme temperatures.

The eclipse will traverse through several U.S. states, into Canada, and finally exit into the Atlantic Ocean. Scientists are looking forward to the event to gather valuable data and insights, especially with the heightened solar activity compared to the 2017 eclipse. With new spacecraft studying the sun and advanced scientific instruments in place, April’s solar eclipse promises a wealth of scientific discoveries.

This eclipse, passing through U.S. radar sites monitoring space weather, will offer a unique opportunity for scientific observation closer to home.

When to Watch the Full Moon during the 2024 Lunar Eclipse Tonight

Let’s prepare for an amazing event. A stunning lunar eclipse is set to occur on Monday, March 25, 2024, when the Earth aligns between the Sun and the Moon. This alignment causes the Earth’s shadow to fall on the Moon, resulting in a dimmer appearance.

This event coincides with the Festival of Colors, a traditional Hindu celebration marking the arrival of spring and new beginnings. For locations more than 6 hours behind GMT (west of Chicago), the eclipse will start on the night of March 24, 2024.

Curious about where to witness a lunar eclipse, the difference between penumbral and umbral solar eclipses, the possibility of the moon turning red, or the astrological sign the moon will be in during a solar eclipse? Find answers to these questions below.

If you’re excited about clear nights this year, consider planning ahead with our UK full moon calendar and beginner’s guide to astronomy.

When does a lunar eclipse occur?

A penumbral lunar eclipse is scheduled for March 24th to 25th, 2024.

For viewers in the UK, the eclipse will take place a few hours before sunrise, with the moon setting as it reaches its maximum phase. In Bristol, the sunrise will be at 6am GMT on March 25th, placing the eclipse in the early morning sky just before the moon sets.

At 6:03 a.m. GMT, the eclipse will peak while the moon is still above the horizon. The true maximum at 7:12 a.m. won’t be visible as the moon will have set by then.

The moon will start to set at 6:11 a.m. GMT, but its proximity to the horizon and the eclipse phase may dim it before its descent, possibly making it almost invisible.

During a lunar eclipse, the moon will be above the horizon, providing better visibility for observers in the United States.

For Bristol, UK:

  • A penumbral solar eclipse begins: March 25th, 4:53 a.m. GMT (Moon visible on the horizon)
  • Maximum eclipse: March 25, 7:12 a.m. GMT (moon below the horizon)
  • Penumbral eclipse ends: March 25, 9:32 a.m. GMT (moon below the horizon)

For New York City, USA:

  • A penumbral solar eclipse begins: March 25th 12:53am ET (Moon visible above the horizon)
  • Maximum eclipse: March 25th, 3:12 a.m. ET (Moon visible on the horizon)
  • Penumbral eclipse ends: March 25th, 5:32am ET (moon visible on the horizon)

For San Francisco, USA:

  • A penumbral solar eclipse begins: March 24th, 9:53 PM PST* (Moon visible on the horizon)
  • Maximum eclipse: March 25th, 12:12am PST (Moon visible on the horizon)
  • Penumbral eclipse ends: March 25th, 2:32 a.m. PST (Moon visible on the horizon)

* In the United States, clocks changed to daylight saving time on March 10th. In the UK, clocks change to BST on March 31st.

Where can I see the lunar eclipse?

The lunar eclipse on March 25, 2024, will be visible across the United States, South America, Canada, the United Kingdom, Europe, Africa, Asia, Western Australia, and the Arctic and Antarctic regions.

For locations west of Chicago, Illinois, the eclipse will begin on March 24 and last until sunrise.

What exactly is a penumbral eclipse?

All objects cast two shadows when in front of a light source: the dark umbra and the bright penumbra. This remains true when the Earth is between the Sun and the Moon.

During a lunar eclipse, when the moon enters Earth’s penumbra, a partial shadow is formed. Penumbral eclipses are subtle and may be challenging to observe. On Earth, this translates to a gradual dimming of the Moon’s brightness.

During a total lunar eclipse, as the Moon enters Earth’s umbra, it takes on a reddish hue for a more dramatic effect. The intensity of the red color depends on the Moon’s position in Earth’s shadow, appearing blood red in the deepest shadow and pale red in partial shadow.

For future lunar residents, standing on the Moon during a lunar eclipse would reveal Earth blocking the Sun, a scenario where a solar eclipse is witnessed.

What causes a lunar eclipse?

A lunar eclipse occurs when the Earth moves in front of the Sun, casting its shadow on the Moon. Since the Moon reflects sunlight back to us, its visibility during a lunar eclipse is affected when this sunlight is obstructed.

There are different stages to a lunar eclipse: transition through Earth’s penumbra, entry into the dark umbra, return to the penumbra, and finally exit from the shadow completely.

During the upcoming lunar eclipse on March 24-25, 2024, the Moon will stay within the penumbra without entering the central umbra.

What constellation is the moon in?

The penumbral eclipse on March 24-25, 2024, will take place while the Moon is in Virgo, mirroring the placement of Spica, the brightest object in the constellation but slightly to the west.

Will the moon turn red?

Unfortunately, the lunar eclipse on March 24-25, 2024, will not be total, meaning the Moon will not turn red. At most, observant viewers may notice a slight darkening, far less dramatic than during a total lunar eclipse.

Under most circumstances, the lunar eclipse will go unnoticed: “Regrettably, this full moon will only pass through Earth’s darker outer shadow. The lunar eclipse will not be observable at all!” Dr. Darren Baskill, University of Sussex, remarks.

To visualize the distinction, Dr. Baskill suggests placing your hand between a bright light and a surface at night, observing the fainter penumbra surrounding the dark umbra of your hand.

Why do solar eclipses come in pairs?

Observant viewers will notice solar and lunar eclipses occurring successively. After the lunar eclipse on March 24-25, 2024, a solar eclipse will follow on April 8, 2024, promising an even more impressive celestial event.

This phenomenon arises from the alignment of the Sun, Earth, Moon, and their orbital planes.

The Moon’s orbit is slightly inclined compared to Earth’s orbit around the Sun, leading it to pass slightly above or below Earth’s orbital path. Despite this, specific points where the Moon’s orbit intersects Earth’s orbital path—termed “nodes”—exist.

During a solar eclipse season, recurring approximately every six months, alignments near these nodes permit both solar and lunar eclipses to occur. The full moon’s passage through Earth’s shadow creates a lunar eclipse, which is followed by a solar eclipse two weeks later, during the new moon phase, with the Sun, Earth, and Moon aligning perfectly.

When is the next lunar eclipse?

Following March 25, 2024, a partial lunar eclipse is slated for September 18, 2024, preceding a total lunar eclipse about a year later, on March 14, 2025.

Subsequent total lunar eclipses will occur in three consecutive instances, on September 7, 2025, and March 3, 2026.

Here is a list of upcoming lunar eclipses:

  • March 25, 2024: penumbra
  • September 18, 2024: Partial
  • March 14, 2025: total
  • September 7, 2025: total
  • March 3, 2026: total
  • August 28, 2026: Partial
  • February 20, 2027: penumbra
  • July 18, 2027: penumbra
  • August 17, 2027: penumbra
  • January 12, 2028: Partial
  • July 6, 2028: Partial
  • December 31, 2028: total
  • June 26, 2029: total
  • December 20, 2029: total

Tips for viewing the lunar eclipse

No special equipment is needed to observe a lunar eclipse, as it is entirely safe to view the moon even during the event. The moon reflects sunlight and lacks dangerous radiation. Therefore, it poses no threat to human eyes.

On a clear night, simply use your eyes to witness the eclipse. A reclining chair may enhance comfort during outdoor viewing. For UK spectators, the eclipse will transpire before dawn, with the moon low on the horizon, possibly visible from indoors if not obstructed by foliage.

To maximize visibility, avoiding areas with high light pollution remains crucial.

Stunning Images from Utah’s Annular Solar Eclipse Last Year

Daniel J. Stein and Andrew McCarthy

This mesmerizing shot of the perfect alignment of the sun and full moon over Utah's Valley of the Gods last October is raising expectations for next month's total solar eclipse in North America.

This image, a collaboration between photographers Andrew McCarthy and Daniel Stein, shows an annular solar eclipse in which an outer “ring of fire” forms because the moon is too far from Earth to completely cover the sun. I am. The shot is the result of digitally stitching together thousands of images, combining Stein's landscape photography skills with McCarthy's experience capturing images of the sun.

After months of planning, the pair set up cameras and telescopes at carefully selected desert locations to capture the key shots, taking into account weather patterns, eclipse duration, and terrain features. did.

The image was published by Social media March 8th, exactly one month before a total solar eclipse, in which the moon completely covers the sun, will pass over North America. It will blanket much of the continent in darkness or completely, from Canada to the United States and Mexico. The path of the total eclipse will be much wider than the last similar solar eclipse in the region, covering almost 200 kilometers compared to about 115 kilometers in 2017.

“It’s easy to take the sun for granted, but [sun and moon] When combined during a solar eclipse, they are breathtakingly beautiful. I feel that incorporating landscape elements adds a sense of grounding to the images and allows the viewer to connect more deeply with the work,” says Stein.

Capture Stunning Images of the April 2024 Total Solar Eclipse: A Photographer’s Guide

Photographing a solar eclipse takes a little practice

Sebastian Kennerknecht/Minden Pictures/Alamy

Although some people spend years planning trips to see a total solar eclipse, the moment itself lasts only a few minutes at most. A well-taken photo will help you remember the moment years later.

Fortunately, with a little practice, even beginners can capture great images. Learn how to photograph a solar eclipse without any prior experience or fancy camera equipment.

location, location, location

Of course, you can’t photograph a solar eclipse unless you’re in its path. On April 8, everyone in North America will see at least a partial solar eclipse. A partial solar eclipse must be viewed through eclipse glasses and photographed using a solar filter (see details below).

Only those who have entered the path of totality can see the total solar eclipse. Much of the experience will be the same, with partial stages requiring eclipse glasses and eclipse filters, but midway through totality, where the moon completely blocks the sun for several minutes. Only during this period will the eclipse glasses and solar filters come off, allowing you to see and photograph the sun’s corona with the naked eye. This is the shot everyone wants.

How to photograph a total solar eclipse using a smartphone

If you’re in the middle of a totality, forget about handheld video or zooming in on the eclipse sun. The results of using a smartphone will be disappointingly bleak. Instead, focus on taking wide-angle shots that use silhouettes of people and objects to show off their overall beauty.

solar eclipse 2024

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

Just before dark, put your phone into wide-angle mode. Focus on something in the middle distance and press and hold your finger on the screen to lock focus. Burst mode allows you to capture images continuously as soon as totality begins. That way, you can catch the “diamond ring,” the last and first beads of sunlight peeking around the moon just before and after totality.

How to photograph a total solar eclipse with a camera

If you have a manual DSLR or mirrorless camera and a variety of lenses, you can choose to shoot wide-angle or close-up of the eclipse. In partial phases, solar filters should be used.

Just before totality, make sure the partially eclipsed Sun is in focus and set your camera to bracketing mode (if you want to take three different exposures of the same image). “Make sure your camera is shooting at a low ISO (200-400) before and after totality to reduce noise,” he says. Mike Mezur, nature photographer. Remember to remove the solar filter during the diamond ring, take a bracket shot during totality, and put the solar filter back on as soon as he sees the second diamond ring at the end of totality.

How to take photos of a partial solar eclipse

To capture impressive shots of a partially eclipsed sun with your smartphone, you need to use a solar filter and keep your smartphone still. The latter can be done by using a tripod and delaying the shutter for a few seconds. There is no problem if you use solar eclipse glasses for the filter. If you have a spare lens, try cutting out one lens and taping it to your phone’s camera lens. Another option is to purchase a smartphone eclipse filter from a company such as: solar snap or business solar.

Smartphones aren’t prone to damage when pointed at the sun, but don’t point your manual camera at a partially chipped sun unless the lens is protected by a solar filter. You can purchase expensive glass solar filters or make your own using inexpensive Baader AstroSolar safety film.

The steps required to take a photo of a partial solar eclipse are a little more involved than taking a standard selfie, but you can practice ahead of time whenever the sun is clearly visible. “Adjust focus and set exposure manually” Karl Heilman, a New York-based photographer who teaches solar eclipse photography workshops. He recommends using an aperture of f/8-11, a shutter speed of 1/800, and ISO 100.

Also, be careful not to spend all your time fiddling with your camera. “As much as you want to photograph the event, put down your camera and take the time to take it in, because this is one of the most amazing things you’ll ever see,” says Mezur.

‘Devil’s Comet’ makes close approach to the sun, possibly visible during solar eclipse

The Devil’s Comet, known for its occasional explosions, is currently visible in the night sky, and fortunate observers may catch a glimpse of it during the eagerly awaited solar eclipse next month.

Comet 12P/Ponsbrooks earned the nickname “Devil’s Comet” after an eruption last year left behind two distinctive trails of gas and ice resembling devil’s horns.

From the Northern Hemisphere, the comet is currently visible with binoculars or telescopes. As it moves through the inner solar system and approaches its closest point to the sun in mid-April, it may become visible to the naked eye by the end of the month.

Comets typically consist of a core of dust, gas, and ice surrounded by a bright gas cloud called a coma. These objects are remnants from the formation of the solar system and can be several miles wide, according to NASA.

The core of a comet can heat up due to sunlight and solar radiation, sometimes leading to explosive events, as seen with Comet 12P/Ponsbrooks. Observers in the Northern Hemisphere can currently see the comet in the western-northwestern sky in the evening.

The comet is expected to brighten towards the end of the month and, under clear and dark conditions, may remain visible until early May. If the comet experiences significant flares in the coming weeks, it could be visible during the total solar eclipse on April 8 along the path stretching from northeast Texas to Maine.

Despite uncertainties surrounding rare synchronistic events, there is a good chance of spotting the comet on its own in the evening sky. Comet 12P/Pons-Brookes was first discovered in 1812 by French astronomer Jean-Louis Pons and later observed in 1883 by British-American astronomer William Brooks. Due to its 71-year orbit around the sun, sightings of this comet are infrequent.

Unexpected responses of animals during a total solar eclipse

We're still trying to understand how animals react to solar eclipses

Ş. Uğur OKÇu/1001slide/iStockphoto/Getty Images

You can't miss a total solar eclipse. The sun's disk is completely covered by the moon, casting its shadow across the Earth's surface and causing a sharp drop in temperature. Animals seem to notice, too, and researchers around the world are studying how animals respond.

Researchers have observed all kinds of animals, from wild hippos to pet dogs, during the eclipse. However, some of the most thorough research is done in zoos around the world.

adam hartstone rose North Carolina State University and colleagues conducted one of these large-scale studies It was during a solar eclipse that crossed the United States in 2017. “To be honest, I didn't expect to see anything interesting. Animals always see clouds passing overhead, but sometimes it gets cloudy. I never thought I would care about that at all,” says Heartstone-Rose. “Surprisingly, three-quarters of the species we observed showed some kind of response.”

Most of these animals seemed to think that it was night during totality, the period when the sun was completely hidden behind the moon. This may not come as a surprise to anyone who witnessed a solar eclipse somewhere outdoors, as it has been known for centuries that birds and insects tend to become quiet and search for nests. not.

“Gorillas usually hang out in gardens all day and go indoors at night, so it was like a whole herd of gorillas marching towards the front door and I was confused as to why no one would let me in. ” said Hartstone-Rose. . Similarly, he observed birds going to roost and sleeping. Once the totality was over, the gorillas and birds returned to their normal daytime activities. Previous studies have also observed spiders laying down their nests during totality, and bats briefly emerging from their daytime resting spots.

Another response the researchers found in many animals was anxiety. “We have a lot of experience in assessing anxiety in animals, especially zoo animals, because we are always trying to reduce anxiety,” Hartstone-Rose said. say. “So we are very cognizant of behaviors that may indicate anxiety.”

These responses include pacing, huddled, and increased vocalization. “Giraffes generally only run when they need to run for their lives, but during the eclipse, some giraffes started running like the sky was falling,” Hartstone-Rose said. “Several animals showed such reactions.” For example, baboons were seen running around together in groups.

Solar eclipse in 2024

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

Some Galapagos giant tortoises began mating during the eclipse and looked up to the sky after the eclipse passed. Previous research on hippos found that they also remain excited even after the peak of the eclipse.

However, it is difficult to determine which animal behavior is caused by the eclipse itself, and which animal behavior is a reaction to the crowds drawn by the eclipse. This is especially true in zoos where animals and humans are in close contact. For the same reason, it is difficult to draw conclusions about changes in pet behavior during an eclipse.

Hartstone-Rose and her colleagues conducted another survey at the zoo during the total solar eclipse on April 8, observing some of the same species to see if their behavior matched, as well as identifying new species. We plan to collect data on they again, participatory science project Through this, anyone can report animal observations during the eclipse. By exploring the patterns of animal behavior during unusual events like solar eclipses, we may be able to understand animal thought processes more generally.

6 important considerations during a total solar eclipse

Pink stripes called prominences that appear during a total solar eclipse

Alan Dyer/StockTrek Images/Getty Images

There is no greater experience in life than witnessing a total solar eclipse. For a while, the sky darkens, the air cools, and stars appear during the day. Some people may go through life without ever seeing a solar eclipse, but for eclipse chasers like me, that’s not enough.

The thrill of anticipating the next total solar eclipse comes from the fact that each one is completely unique. They can last from 1 second to more than 7 minutes and occur on different types of terrain and geology, usually at sea.

The total solar eclipse on April 8 will be visible only to those along the 185-kilometer-wide path, and the sun will be completely eclipsed for up to 4 minutes and 26 seconds. Just before, during, and after these magical minutes, those on the path to wholeness should be aware of a variety of phenomena. If the sky is clear, you can expect the following to happen during a total solar eclipse:

sunspot covered by the moon

This is one of those sights that everyone across North America has a chance to see. The sun is currently nearing its most active period in a cycle called solar maximum, which lasts 11 to 17 years. This means that magnetic activity is at its maximum, causing visible sunspots on the sun’s surface. If these dark, cold, magnetically complex regions are large enough, they can be seen through eclipse glasses at any time. Even for those outside the path of totality, it’s an interesting sight to see them gradually covered by the moon during an eclipse.

band of shadow on the ground

For a few minutes to about 30 seconds before the sun is completely eclipsed, only a thin crescent moon appears from the surface of the sun, called the photosphere. When this happens, you may see wavy lines moving quickly across the light-colored surface. “a [bed] A shadow band may appear on sheets or other white surfaces placed on the ground.” frank maloney at Villanova University in Pennsylvania. “These are due to clumps of photosphere light that travel through the atmosphere and essentially ‘flicker’ in roughly parallel bands.” Whether they are visible or not depends on the amount of turbulence in Earth’s atmosphere.

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

Darkness, Bailey’s Beads, and the First Diamond Ring

Just before totality, the last 0.1 percent of the sun disappears and light levels plummet. Now come the beads. “For a few seconds before and after totality, the last bits of the Sun can be seen shining through the moon’s irregular surface, so you might be able to see Bailey’s beads,” Maloney says. The final bead sparkles momentarily like a jewel, just as the sun’s corona appears, creating a brief “diamond halo” effect around the moon. It’s safe to view a diamond ring without eclipse glasses, but most observers will still have their eclipse glasses on and will miss it.

solar corona

One of the most amazing sights in nature is here. “During totality, when the sun’s photosphere is eclipsed, other parts of the sun’s atmosphere, the white corona and the pink and purple chromosphere, become visible,” Maloney said. Darkness has arrived and you can safely remove your eclipse glasses and view the corona with the naked eye. As the Sun approaches the most active phase of its cycle, the corona is expected to resemble a spiky star. If you have binoculars, you can see the thin tendrils growing inside the corona.

pinkish-red chromosphere and prominences

Just before the beginning and end of totality, the chromosphere, the lower region of the sun’s atmosphere, can be seen as a pink band that disappears during the eclipse and reappears on the opposite side as the moon crosses the sun. Masu. You may also see prominences, pinkish-red towers, or loops of plasma and magnetic field structures protruding from the corona visible around the moon.

second diamond ring

The most impactful diamond ring effect appears at the end of the whole thing. Small beads of sunlight appear between the moon’s peaks and valleys, then merge into a single bright diamond ring, the appearance of which marks the end of the whole thing. It’s safe to watch for a few seconds, but once sunlight returns, you’ll need to put your eclipse glasses back on if you want to continue seeing the partial phase.

Once the totality is over, the band of shadow may be seen again. Of course, he can put the eclipse glasses back on and watch the sun and sunspots slowly being exposed for at least another hour.

Safely Viewing the April Solar Eclipse: Tips on Using Eclipse Glasses and Identifying Key Features

Use special eclipse glasses to prevent eye damage

Gino Santa Maria/Shutterstock

Watching a total solar eclipse is an experience you’ll never forget, but if you don’t take the right precautions, it could end up for the wrong reasons. Looking directly at the sun can be dangerous, so read on to learn how to safely observe a solar eclipse and what you need to prepare in advance.

On April 8, 2024, a total solar eclipse will be visible to more than 42 million people across North America. The total path is only about 185 kilometers wide and touches Mexico, 13 U.S. states, and parts of Canada. Most people in North America will experience this phenomenon as a partial solar eclipse, rather than a total solar eclipse.

“For those outside the path of totality, the moon will never completely cover the sun,” he says. Jeff Todd At Prevent Blindness, a Chicago-based eye care advocacy group. No matter how you look at it, eye protection is essential.

“To avoid damaging your eyes, you should wear eclipse glasses throughout the eclipse,” says Todd. Otherwise, you risk burning your retina. This phenomenon, also known as “eclipse blindness,” can occur painlessly and can be permanent. It may take several days after seeing a solar eclipse before you realize something is wrong. Sunglasses do not provide sufficient protection. However, it is perfectly safe to wear eclipse glasses over your prescription glasses.

How to safely view a solar eclipse

The prize for those traveling the path of totality is seeing the sun’s corona with the naked eye. However, it is only visible for a short few minutes during totality. Otherwise, partial phases will be visible and must be observed through eclipse glasses. Todd says people on the path to totality should wear eclipse glasses at all times, except during totality, a brief period of darkness when the sun is completely hidden by the moon. “Only then can you take off your eclipse glasses,” he said.

It is important for those in the path of totality to use their naked eyes to view the Sun during a total solar eclipse. “You have to look without a protective filter, otherwise you won’t see anything,” he says. ralph chow At the University of Waterloo, Canada.

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

Just before totality ends, light from the Sun’s photosphere flows between the Moon’s peaks and valleys. Called Bailey beads, they appear for a few seconds and eventually become a flashing “diamond ring,” exposing enough of the sun’s photosphere for sunlight to return. “It gives us ample warning that it’s time to resume viewing partial solar eclipses with protective filters,” Chow said.

Which solar eclipse glasses should I buy?

It is important to wear eclipse glasses that meet the ISO 12312-2 international standard. ISO 12312-2 applies to products used for direct viewing of the sun. “Look for the ISO standard label and buy your glasses from a trusted source,” says Todd. “Get your glasses early in time for the eclipse.” Before you buy, make sure the company or brand is listed on the American Astronomical Society’s site. A vetted list of suppliers and resellers.

Do not use Eclipse glasses with binoculars or telescopes. If you want to use these instruments to observe a solar eclipse, you’ll need to attach a solar filter over the objective lens (the lens opposite the one you’re looking through). Never place solar filters or eclipse glasses between the telescope eye and the eyepiece or binocular eyecup.

Another way to safely view the eclipse is with a pinhole projector. This is a simple device that projects an image of the sun onto paper or cardboard through a small hole. An even easier method is to use a colander or a small hole in a spaghetti spoon. This projects a small crescent sun onto every surface.

Where and when can you view the solar eclipse of 2024?

In a total solar eclipse, the moon blocks the sun’s light.

Scott Sadie/tahoelight.com/Alamy

A total solar eclipse is coming to North America. On April 8, the moon will pass between the Earth and the sun, perfectly aligned to block the entire disk of the sun in a phenomenon called totality. It will be visible from a strip of land that stretches from Mexico across the United States into Canada.

The eclipse will begin in the Pacific Ocean, about halfway between North America and New Zealand, and will begin to be visible off the west coast of Mexico at 8:42 a.m. local time. It begins as a partial solar eclipse, with the moon slowly moving to cover more and more of the sun. The totality event was first observed in Mexico at 9:38 a.m. local time.

As the sun and moon move across the sky, the eclipse will be visible over a 185-kilometre-wide area of land known in the United States as totality. It will pass through 13 states, from Texas to Maine, and enter southern Ontario, Canada. The last place to see the eclipse on land will be Newfoundland, where the sun’s visibility will return to normal at 5:16 p.m. local time.

The duration of totality varies by location, from less than 2 minutes to nearly 4.5 minutes. This is because the moon’s orbit around the Earth is not a perfect circle, and neither is the Earth’s orbit around the sun, so the distances between the three bodies change throughout the day.

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

During a total solar eclipse, the moon’s shadow moves across the ground at speeds of over 2400 kilometers per hour, forming a dark patch that darts along the ground. In this shadow, the temperature drops rapidly and the sky becomes strangely dark, making planets and stars visible even during the day. Total solar eclipses are important to scientists because they provide a rare opportunity to measure the outermost layer of the sun, called the corona. This tenuous layer is much fainter than the Sun’s disk, making it difficult to observe normally.

Viewers in areas just outside the total path will also be able to see the eclipse, but it will only be partial, with the moon covering a smaller portion of the sun. A partial solar eclipse will last about 3 hours. Partial solar eclipses, which include the period just before and after a total solar eclipse, must be viewed through a special solar filter. Such filters are available in the form of eclipse glasses. However, regular sunglasses do not provide sufficient protection for the viewer’s eyes. Do not look directly at the sun without a solar filter, even during a partial solar eclipse.

If you don’t have eclipse glasses, don’t despair. A partial solar eclipse can still be seen, just not directly. You can use any object with holes, such as a colander or paper with pinholes, to project an image in the shape of an eclipse onto a screen or onto the ground. Even between the leaves of the trees the ground is speckled with strange sunlight that changes like a crescent moon.

Delta Airlines offers eclipse viewing flight as airlines seek to profit from solar phenomenon

Passengers who book special Delta flights will have the opportunity to witness the total solar eclipse in April from a unique perspective at 30,000 feet.

The airline revealed on Monday that it will be offering flights from Dallas-Fort Worth to Detroit on April 8, allowing passengers to maximize their time within the eclipse’s “total path.”

The eclipse is anticipated to be a significant event as it travels through various populated areas of North America, including parts of Mexico, the continental United States, and eastern Canada. In the U.S. alone, millions of sky gazers from Texas to Maine will have the chance to witness this rare astronomical occurrence.

A solar eclipse happens when the moon moves between the Earth and the sun, temporarily blocking the sun’s light. Within the approximately 100-mile-wide strip known as the Path of Totality, observers will witness the moon completely obscuring the sun, creating a darkened afternoon sky.

Delta Airlines is providing eclipse enthusiasts with another option to experience the April event. The flight announced on Monday will be the airline’s second full charter scheduled for April 8. The initial flight from Austin, Texas to Detroit was announced on February 19 and sold out within 24 hours, according to the company.

The Austin to Detroit flight (Delta Flight 1218) is on an A220-300 aircraft, departing from Texas at 12:15pm Central Time and arriving in Detroit at 4:20pm Eastern Time.

The flight from Dallas-Fort Worth to Detroit (Delta Flight 1010) is operated on a large A321neo plane, departing Texas at 12:30 PM (Central Time) and landing in Detroit at 4:20 PM (Eastern Time).

While the flights are designed to maximize time within the total path, they are subject to potential changes due to factors like weather conditions and air traffic control.

For detailed booking information, visit the following website: Delta.com.

The upcoming solar eclipse is poised to be a major draw for travel and tourism, with many businesses already capitalizing on it. Hotels are offering special solar eclipse packages, while state tourism departments are organizing various events tied to the cosmic phenomenon.

During the April eclipse, the total path will traverse through states like Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. In certain areas of Michigan and Tennessee, totality may be visible if weather conditions are clear.

In other parts of the continental U.S., observers will witness a partial solar eclipse, where the moon appears to “take a bite” out of the sun and only partially obscures it in the sky.

To safely observe the eclipse, use eclipse glasses or a pinhole projector to avoid eye damage. Never look directly at the sun during a solar eclipse, even when it is partially or mostly covered by the moon.

How to Safely Watch the Rare “Ring of Fire” Eclipse

A total solar eclipse is set to pass over North America in April, offering millions of skywatchers the rare chance to witness the afternoon sky briefly darken and a “ring of fire” appear overhead. The upcoming April 8 solar eclipse is expected to be a significant event, as its path will traverse parts of Mexico, the continental United States, and eastern Canada. Weather permitting, skywatchers in 15 states in the US will have the opportunity to see the moon almost completely block the sun, casting its shadow in a fiery circle and creating a halo effect in the sky. In all other states in the continental US, viewers will witness a partial solar eclipse where the moon appears to partially obscure the sun.

Here is everything you need to know about the upcoming total solar eclipse.

How to safely view a solar eclipse

It is crucial not to look directly at the sun during a solar eclipse, even if it is partially or mostly covered by the moon. Special eclipse glasses or a pinhole projector are necessary to safely view the eclipse and prevent eye damage. Sky observers should never look at the Sun through binoculars, telescopes, or camera lenses without a solar filter installed. Using Eclipse glasses is essential, as failure to do so can result in serious eye damage. NASA advises taking proper precautions. During the total solar eclipse when the moon completely blocks the sun, it is safe to view with the naked eye, but at all other times, eclipse glasses are required.

What is a solar eclipse?

A solar eclipse occurs when the sun, moon, and earth align, with the moon passing in front of the sun to temporarily block its light. The moon can either completely obscure the sun in a total solar eclipse or partially block its light in a partial solar eclipse.

Who can see it?

This eclipse is rare because it will cross populated areas of the United States compared to other recent total solar eclipses. NASA estimates that approximately 31.6 million people will live within the 160-mile-wide total path, with an additional 150 million living within 200 miles of the path. The eclipse will pass through various states in the US and enter Canada through provinces such as Ontario, Quebec, and New Brunswick.

While the most spectacular views will be within the total eclipse path, there are still opportunities for people across the continent to witness the astronomical event. A partial solar eclipse will be visible in all 48 states of the continental US, and NASA will stream a live view of the total solar eclipse online.

When will it happen?

The timing and duration of totality will vary by location, with some areas experiencing darkness and the “ring of fire” for up to 4 minutes and 28 seconds. Various resources online, including NASA, NationalEclipse.com, and timeanddate.com, provide information for planning and expectations on the day of the eclipse.

Specific timings for some populous cities along the path of totality are as follows:

Dallas: Partial eclipse begins at 12:23 PM CT. Totality begins at 1:40 PM CT. Totality ends at 1:44 PM CT. Partial eclipse ends at 3:02 PM CT.

Little Rock, AR: Partial eclipse begins at 12:33 PM CT. Totality begins at 1:51 PM CT. Totality ends at 1:54 PM CT. Partial eclipse ends at 3:11 PM CT.

Cleveland: Partial eclipse begins at 1:59 PM ET. Totality begins at 3:13 PM ET. Totality ends at 3:17 PM ET. Partial eclipse ends at 4:29 PM ET.

Buffalo, New York: Partial eclipse begins at 2:04 PM ET. Totality begins at 3:18 PM ET. Totality ends at 3:22 PM ET. Partial eclipse ends at 4:32 PM ET.

Lancaster, New Hampshire: Partial eclipse begins at 2:16 PM ET. Totality begins at 3:27 PM ET. Totality ends at 3:30 PM ET. Partial eclipse ends at 4:38 PM ET.

Here’s How to Prepare for the 2024 Total Solar Eclipse

Bride, groom and wedding guests watching solar eclipse in Mexico

Martin Zetina/AP/Alamy

On April 8, 2024, a total solar eclipse will be visible in North America from a strip of land that begins in Mexico and ends in Canada, passing through 13 U.S. states.

A solar eclipse can be seen from many different locations, but it's important to know exactly where to look to get the full experience. The part of the Earth's surface where a total solar eclipse is visible is called the total path, and is only 185 kilometers wide. Viewers in other parts of North America will see a partial solar eclipse.You can check This NASA map confirm.

A solar eclipse occurs when the Earth, Moon, and Sun are aligned and the Moon blocks the sun's light. If aligned properly, it is large enough to cause a total solar eclipse. The moon orbits the Earth each month at a tilt of just over 5 degrees compared to the Earth's orbit around the sun. This means that it is not very often that the three line up perfectly.

All solar eclipses start out partial, with only part of the sun blocked out. However, a total solar eclipse has a special middle part called totality, where the moon blocks out all of the sun's light.

Never look directly at the sun during a partial solar eclipse. You can use eclipse glasses to view it, but not regular sunglasses. Observe the event indirectly by using eclipse filters for binoculars or telescopes designed for this purpose, or by creating an eclipse viewer using a pinhole camera that projects the eclipse. You can also. You can also use something like a colander with small holes in it.

A partial solar eclipse will last just under 3 hours. For those lucky enough to step onto the path to wholeness, the 2024 event will be special. Some total solar eclipses last longer than others because the moon's orbit moves it closer and further away from Earth at different times. This totality lasts more than four minutes. Totality is the only time you can see the sun directly without a solar filter.

A total solar eclipse is an amazing experience. Temperatures drop sharply, days become darker, and stars and planets become visible.Even before and after totality, strange shadows and so-called diamond ring – A bright flash of light that occurs when sunlight passes along the uneven surface of the moon.
