The Jellyfish Nebula in Gemini (more mundanely known as IC 443) is the remnant of a supernova that occurred approximately 30,000 years ago. The shock wave impacted the surrounding dust and gas in the region, causing its delicate tendrils to glow. All that is left of the progenitor is a tiny neutron star.

Hi
I thought you might be interested in entering it in the Astronomy Photographer of the Year group?
It's a pretty cool project run by the Royal Observatory in Greenwich, London- the home of the Greenwich Meridian!
They are accepting entries from amateurs with basic camera gear and pros with the long lenses, etc.
You should considering entering this!
