IC443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from the Earth. IC443 may be the remains of a supernova that occurred 30,000 to 35,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.
