celestial body - a naturally occuring object in space such as a star, planet, moon, asteroid, galaxy, or a comet corona - the outermost layer of the Sun. It stretches far into space, appears very thin and faint and can only be seen from Earth during a total solar eclipse. flare - a tremendous explosion on the Sun that happens when energy stored in magnetic fields is suddenly released. rays - bright streaks of surface material thrown from a crater and extending away for great distances sunspot - dark spots that can be observed on the photosphere. They are cooler than the surrounding gas. It can last from one hour up to several months. core - the center of the sun, the hottest part chromosphere - the layer of gas above the photosphere. It is a jagged outer layer and is constantly changing photosphere - the first layer of the Sun’s atmosphere convection zone - heated gases expand and rise. When they cool, they become denser and sink back down again. These circulating gases form this zone. revolution - one complete trip of a planet around the sun impact crater - craters formed when objects or meteorites smash into the surface satellite - a celestial body or man made object that revolves around a larger body.
