IC 443 (also known as the Jellyfish Nebula) 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 (~5×1016
km) from Earth.
IC 443 is thought to be the remains of a supernova 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 stellar core.
IC 443 is one of the best-studied case of supernova remnant interacting with
surrounding molecular clouds.
