IC 443 is also known as the Jellyfish Nebula or Sharpless 248 (Sh2-248). It is located in the constellation Gemini and is a Galactic supernova remnant (SNR) at some 5000 light years from Earth that spreads 70 light years across.
IC 443 the remains of a supernova that occurred between 3000 and 3,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core.
