IC 443 (also known as the Jellyfish Nebula and Sharpless 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.
It was likely formed 30,000 years ago in the supernova that created the supernova remnant IC 443, the "Jellyfish Nebula." [ 2 ] [ 3 ] [ 4 ] It is travelling at approximately 800,000 km/h away from the site.
Astronomers from the INAF-Palermo Astronomical Observatory modeled a supernova remnant called IC 443 or the Jellyfish Nebula, showing just how weird they can get.
PGC 1228197 is classified as a jellyfish galaxy. [5] [6] It has a lengthy tail that is ≥90 kpc wide, with ionized gas stripped from the galaxy. [7] The galaxy is surrounded by its own magnetized intracluster medium drape. [8] Such process is caused when it interacts with other galaxies causing it to run into intracluster medium.
A jellyfish galaxy is a type of galaxy found in galaxy clusters. They are characterised by ram pressure stripping of gas from the affected galaxy by the intracluster medium , triggering starbursts along a tail of gas.

The St. George’s cross medusa jellyfish is considered “large,” measuring about 4 inches wide and about 3 inches tall, the study said. It has a circular body shape and about 240 tentacles.
The Tribune asked PG&E about how emergency incidents are reported at the plant. Here’s a some events in recent years.
