Description

The Jellyfish Nebula ( IC 433, Sh2-248 ) is a supernova remnant located about 5,000 light years from Earth in the constellation of Gemini. It has an angular diameter of 50 arcmin which is about 1.7 full Moon widths. The SNR is abundant in SII (red), Ha (green) and OIII (blue) emissions.
