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.
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.
IC – (catalog) Index Catalog; IC – (celestial object) Intracluster, either the regions between stars in star clusters or the region between galaxies in galaxy clusters; ICE – (spacecraft) International Comet Explorer; ICM – (celestial object) intracluster medium, is the superheated gas present at the center of a galaxy cluster
High school students, using Chandra data, discovered a neutron star in supernova remnant IC 443. [31] Observations by Chandra and BeppoSAX suggest that gamma-ray bursts occur in star-forming regions. Chandra data suggested that RX J1856.5-3754 and 3C58, previously thought to be pulsars, might be even denser objects: quark stars. These results ...
This is a partial list of IC objects, which are astronomical objects included in the Index Catalogue of Nebulae and Clusters of Stars. This two volume catalog was published in 1895 and 1908 by J. E. L. Dreyer. The constellation information for this table is available from the NGC2000.0: Complete New General Catalog and Index Catalog. [1]
