Atmosphere: An envelope of gas surrounding the Earth, another planet, or the Moon.
Average: Term (in science) for arithmetic mean. The sum of a number group divided by the size of the group.
Coronal Mass Ejection: A powerful ejection of giant gas bubbles through magnetic field lines. These can be exhaled by the sun over several hours. Sometimes accompanied by solar flares, but usually not.
Solar Eclipse: This occurs when two celestial bodies line up in space and one completely or partially obscures the other. During a solar eclipse, the sun, moon, and earth line up in that order. The moon casts a shadow on the earth. When viewed from Earth, the moon appears to be blocking the sun. During a lunar eclipse, her three celestial bodies, the sun, earth, and moon, line up in different orders, causing the earth to cast a shadow on the moon, making it bright red.
Field: (in physics) a region in space in which certain physical effects act, such as magnetism (generated by a magnetic field), gravity (by a gravitational field), mass (by the Higgs field), or electricity (by an electric field).
Grid: (in electricity) an interconnected system of power lines that transports power over long distances. In North America, this electrical grid connects power plants and communities in most parts of the continent.
Magnet: A substance, usually containing iron, whose atoms are arranged in such a way that they attract certain metals.
Magnetic Field: An area of influence created by the movement of a certain substance, or electric charge, called a magnet.
Magnetic Field Lines: A line surrounding a magnet (you can see this by dropping iron filings around the end of a bar magnet).
Mass: A number that indicates how much an object resists acceleration and deceleration. Basically, it is a measure of how much material an object is made of.
Power Outage: (in energy) a term used to describe an area that has temporarily lost power (usually electric power) or the ability to operate.
Plasma: (in chemistry and physics) the gaseous state of a substance in which electrons are separated from atoms. Plasma contains both positively and negatively charged particles.
Satellite: A moon orbiting a planet, or a vehicle or other manufactured object orbiting a celestial body in space.
Sun: It has to do with the sun or the radiation it emits. It comes from sol means sun in Latin.
Solar Cycle: Also known as the sunspot cycle, this is a period of about 11 years in which the Sun undergoes various changes as the star oscillates between periods of minimum and maximum activity. The number of sunspots changes (down to near zero at minimum). The value of the magnetic field on the sun's surface also changes.
Solar Eclipse: A phenomenon in which the moon passes between the Earth and the sun, at least partially obscuring the sun. In a total solar eclipse, the moon appears to cover the entire sun, revealing the outer layer of the sun. When observing a solar eclipse from space, you can see the moon's shadow moving in a straight line across the Earth's surface.
Solar Flare: An explosive event that occurs on the Sun when energy stored in a “twisted” magnetic field (usually above a sunspot) is suddenly released. The energy heats up to millions of degrees in minutes, releasing explosive energy. That energy consists of radiation across the electromagnetic spectrum, from gamma rays to radio waves.
Star: The basic building blocks that make up galaxies. Stars develop when clouds of gas are compressed by gravity. When a star gets hot enough, it emits light and sometimes other forms of electromagnetic radiation. The sun is the closest star to us.
Sun: The star at the center of Earth's solar system. It is located approximately 27,000 light years from the center of the Milky Way galaxy. It is also a word that refers to a star like the sun.
Sunspot: A speck or speck that sometimes appears on the surface of the sun, appearing dark in contrast to its surroundings.
Technology: The application of scientific knowledge for practical purposes, especially in industry, or the devices, processes, and systems resulting from such efforts.
