IC 443 Jellyfish Nebula

The Jellyfish Nebula is a galactic supernova remnant located in the constellation Gemini roughly 5000 light-years away from Earth.

When a massive star runs out of thermonuclear fuel it implodes forming what is known as a neutron star. The outer layers of the star collapse towards the neutron star and then bounce outward in a violent explosion known as a supernova.
