Lord of the Rings
The photograph shows the remains of a star that has exploded in what astronomers call a supernova explosion. There are different types of supernova explosions. The kind that created the remains shown here is called a ‘Type 1a Supernova’. Such supernova explosions are useful to astronomers, as they allow them to work out distances in the Universe.
