The Jellyfish NebulaThe star Propus (ηGem) IC 443
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.
