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 plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 30,000 - 35,000 years ago.

The Jellyfish Nebula (IC 443) is a supernova remnant located in the constellation Gemini. This nebula is approximately 5000 light-years from Earth and is estimated to be roughly 70 light-years in size.

In fact, the cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. Light from the explosion first reached planet Earth over 30,000 years ago.

Aug 23, 2015 · The Jellyfish Nebula (IC 443, Sharpless 248) is a supernova remnant located in the constellation Gemini. It lies at an approximate distance of 5,000 light years from Earth and has an apparent magnitude of 12.

Mar 14, 2020 · IC 443 is a beautiful remnant of the explosion that has the shape of a jellyfish. Although IC 443 is pretty challenging to image, it still has a spot in our guide to the 15 best targets to image in Spring.

Jan 1, 2024 · IC 443 isn’t small. It has a diameter of 50′, which means it covers 2.8 times as much area as the Full Moon. Because it is so large and diffuse, it’s a much better target for imagers than for...
