| Comment |
IC443 is a supernova remnant located in the constellation Gemini and is believed to have formed approximately 30,000 years ago due to a violent explosion of the star G189.6+3.3. The nebula's shape represents an expanding shell of gas scattered by strong interstellar winds from the explosion. IC443 is located 5,000 light-years away. This hybrid image is a LLRGB composite. Data acquired on the Lightbuckets 20" and 24" RCOS. |
