Description

The central star (the dolphin's eye) is a Wolf-Rayet star. About 20 times the mass of our sun it has burned all of it hydrogen and is now burning helium and other heavier elements, which means it is approaching the end of its life and is expected to go nova in about a thousand years. The blue nebula is highly ionized hydrogen, blown off from the surface of the star. It's about 60 light years across and expanding at about 3.8 million miles per hour.
