Spectacular cosmic bubble '60 light years wide and 70,000 years old'
This spectacular cosmic bubble was caused by a gas expulsion from a dying star and is 60 light years across and 70,000 years old.
At its centre is a star, known as a Wolf-Rayet star which is 20 times the mass of the sun.
When it dies it throws out gas, creating winds which form the bubble.
It will eventually explode into a supernova.
