An explosion of a star is known as a supernova (Its plural form is "supernovae".).

There is about one supernova explosion every second in the universe. Each stellar explosion can briefly shine as brightly as the combined light of all of the stars in an entire galaxy.

The resulting cloud of debris produces what is known as a supernova remnant and is shown in the animation above.
