bright arch-like loops that may erupt from the photosphere into the corona. Often associated with Sunspot activity, they release large amounts of energy into outer space.
Tool used to collect the light from distant stars and separate that light into bands of different colors; by studying these bands, astronomers identify the elements in a star.

chunks of rock that burn upon entering a planet’s atmosphere.
