New images taken with the NASA/ESA Hubble Space Telescope show a small area of the Small Magellanic Cloud, one of the closest galaxies to the Milky Way.

Small Magellanic Cloud is an elongated dwarf galaxy known for its less prominent bars and eastern expansions.

Also known as the NGC 292 or LEDA 3085, it is about 200,000 light years away from Earth, extending 7,000 light years.

“Most of the Small Magellanic Cloud is found in the constellations of Tucana, but small sections cross the adjacent constellations of Hydos,” said Hubble astronomers.

“Thanks to its proximity, the Small Magellanic Cloud is one of the few galaxies that can be seen from Earth without the help of telescopes or binoculars.”

“For viewers in the Southern Hemisphere and some latitudes in the Northern Hemisphere, the Small Magellanic Cloud resembles parts of the broken Milky Way, but in reality, it is farther than any part of our own galaxy.”

The new Hubble image captures a small area of the Small Magellanic Cloud near the center of NGC 346.

Images were made from individual exposures taken with UV light. Hubble Wide Field Camera 3 (WFC3).

“With the 2.4m 'eyes' and sensitive instruments, Hubble's view of the Small Magellanic Cloud is much more detailed and clearer than what humans can see,” the astronomer said.

“I used a wide field camera 3 instruments from Hubble. Observe This scene is through four different filters. “

“Each filter recognizes light of different wavelengths and creates a multicolored view of dust clouds floating through the field of stars.”

“But Hubble's view is much zoomed in than our eyes, so it's better to observe objects that are very far away.”

The Hubble Space Telescope zooms in on the heart of NGC 4753

NGC 4753 is characterized by a bright white core and distinct dust lanes around the core.

NGC4753 It is located approximately 60 million light years away in the constellation Virgo.

Also known as LEDA 43671, UGC 8009, or IRAS 12498-0055, this lenticular galaxy was discovered by German-born British astronomer William Herschel on February 22, 1784.

NGC 4753 is a member of galaxy group NGC 4753 in the Virgo II cloud, a collection of at least 100 galaxy clusters and individual galaxies extending from the southern edge of the Virgo Supercluster.

“NGC 4753 is thought to be the result of a galaxy merger with a nearby dwarf galaxy about 1.3 billion years ago,” Hubble astronomers said in a statement.

“The unique dust lanes around the galactic cores are thought to be formed by this merging event.”

“Most of the galaxy's mass is now thought to reside within a slightly flattened spherical halo of dark matter.”

“Dark matter is a type of matter that cannot currently be directly observed, but it is thought to make up about 85% of all matter in the universe,” the researchers said.

“It is called 'dark' because it does not appear to interact with electromagnetic fields and therefore does not appear to emit, reflect, or refract light.”

“This object is also of scientific interest for testing various theories about the formation of lenticular galaxies, given its low-density environment and complex structure.”

“Additionally, this galaxy has experienced two known Type Ia supernovae.”

“These types of supernovae are very important because they are caused by the explosion of a white dwarf star with a companion star and always peak at the same brightness, or 5 billion times brighter than the Sun.”

“Knowing the true brightness of these events and comparing it to their apparent brightness gives astronomers a unique opportunity to measure distances in the universe.”

This new image of NGC 4753 consists of observations from Hubble's Wide Field Camera 3 (WFC3) found in the ultraviolet and optical parts of the spectrum.

Two filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
