IC 443 (also known as the Jellyfish Nebula and Sharpless
248 (Sh2-248)) is a Galactic supernova remnant (SNR)
in the constellation Gemini. On the plan of the sky,
it is located near the star Eta Geminorum. 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.
The same supernova event likely created the neutron star
CXOU J061705.3+222127, the collapsed remnant of the
IC 443 is one of the best-studied cases of supernova
remnants interacting with surrounding molecular clouds.
