IC443 - The Jelly Fish Nebula
A massive supernova remnant in the constellation of Gemini.
Supernova are vital astronomical events where a star literally explodes scattering the heavy elements, made during its lifetime, into space to be reused in new stars and planets.
Your gold jewellery originated in a supernova - how cool is that?
There are three shells, or shockwaves, of ionised gases present in the Jelly Fish, one of which may predate the supernova event which occurred between 3,000 and 30,000 years ago.
