IC 443 (Jellyfish Nebula)
IC 443 (Jellyfish Nebula or Sharpless 248) is a supernova remnant in the constellation Gemini. Its distance from Earth is about 5,000 light years. IC 443, which is probably remnant of a supernova that exploded 3,000 - 30,000 years ago, is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.
