about Supernovae!
GCSE Basic Facts
Massive stars die in a violent explosion when they come to
the end of their lives. They first expand into huge Supergiant
stars which are unstable. The Supergiant collapses and
flies apart in an explosion called a Supernova. A Supernova
explosion is the biggest explosion known in the Universe
and can be as bright as a billion Suns!
