NGC 2441

NGC 2441 is a barred spiral galaxy located in the northern constellation of Camelopardalis.[2] A Type 1a supernova, SN1995E, occurred in NGC 2441, and observations suggest it may display a light echo, where light from the supernova is reflected from matter along our line of sight, making it appear to "echo" outwards from the source.[2] The diameter of the galaxy is about 130,000 light-years.
