Description

The Jellyfish Nebula (IC 443 is a galactic supernova remnant (SNR) in the constellation Gemini. The Jellyfish Nebula appeared 3,000 to 30,000 years ago when a supernova occurred in our galaxy, it resembles a jellyfish dragging its tentacles deep in the ocean.

Its distance is roughly 5,000 light-years from Earth. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

When a massive star runs out of thermonuclear fuel, it implodes, forming a dense stellar core called a neutron star. The outer layers of the star collapse toward the neutron star then bounce outward in a supernova explosion.
