IC 443 (also known as the Jellyfish Nebula) is a galactic supernova remnant (SNR) in the constellation Gemini. Its distance is roughly 5,000 light years from Earth.
IC 443 may be the remains of a supernova that occurred 3,000 – 30,000 years ago. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.
