Supernova SN1995E in NGC 2441

Visible as a small dot at the approximate center of this image. Supernova SN1995E, discovered in 1995 as its name suggests, is a type of supernova is found in binary systems, where one star — a white dwarf — drags matter from its orbiting companion until it becomes unstable and explodes violently. More recent observations of this supernova have suggested that it may display a phenomenon known as a light echo, where light is scattered and deflected by dust along our line of sight, making it appear to “echo” outwards from the source.
