Excerpt: 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 ( 5x10 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. The Supernova Remnant IC 443. The image combines optical data from the Digitized Sky Survey (in yellow) and X-ray data from the XMM-Newton Observatory (in blue). The bright spot is the star Eta Geminorum. In the image North is up, East is left. Credit: XMM-Newton/DSSIC 443 is an extended source, having an angular diameter of 50 arcmin (by comparison, the full moon is 30 arcmin across). At the estimated distance of 5,000 ly (1,500 p...
