:: Supernovae

Supernovae are the result of an explosion of a very big star which is finishing its life.
Supernovae are almost 8 times bigger than the sun. At some point, the supernova shines more than a galaxy and has more energy than 200 million stars like the sun!!!In the center of the supernova a star remains : it is called a pulsar.
