Supernovae (incl. Remnants)

A supernova is an extremely bright and energetic explosion of a massive star. It marks the end of the life cycle of a star that must be at least about 1.4 times the mass of our Sun. 

The brightness of a supernova can, for a brief period, be as great as the entire galaxy in which it resides. During this short time, supernovae can emit more light than billions of normal stars. They are also significant sources for the formation of heavy elements, as they eject these elements into the surrounding space during the explosion.
