Supernova explosion in a distant galaxy

Astronomers have used a clever technique to measure how stars have been born since the beginning of time, and wound up finding out how many photons there are in the Universe as a by-product.

An exploding star hundreds of light-years from Earth may have played a role in the minor mass extinction 2.59 million years ago.

A supernova exploded near Earth about 2.5 million years ago, possibly causing an extinction event.

The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the explosion which created this supernova remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light about 11,000 years to reach us.

The image shows a supernova. A supernova is a powerful explosion that occurs at the end of a star's life. The explosion is so powerful that it can outshine an entire galaxy. Supernovas are responsible for creating many of the elements that we see around us, including the oxygen we breathe and the iron in our blood.
