Description:

The Jellyfish Nebula, IC 443, is a large supernova remnant in the constellation Gemini. The emission of the nebula is due primarily to the excitation of atoms as the rapidly expanding shell collides with the surrounding molecular gas. This image of IC 443 was taken through a SII filter (Astrodon 5 nm SII filter) shows, in particular, the light produced by the excitation of sulfur atoms. Image was a total of 8 hrs 20 min exposure.
