IC 444 & IC 443
There is a 2023 image of this area HERE
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 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 cases of supernova remnants interacting with surrounding molecular clouds.
IC 444 is in the upper section of the top image. It is a small, 32 square arcminute reflection nebula - that holds a little secret.
When data is processed in Hubble Pallet an interesting blue cloud pops up and stimulates the imagination - see upper left in the lower image. A possible planetary nebula? I have yet to find out for sure. (First noted by Howell & Crisp in 2006).
