NGC1961 is a distorted spiral galaxy located in the direction of the Constellation Camelopardalis at a distance of between 171 and 200 Million Light-Years, and is the largest galaxy in the local universe. Its visable light size is over 200,000 Light-Years in diameter, thus showing up very nicely at this image scale. Astronomers are puzzled about its distorted morphology, since there is no influencing galaxy in its vicinity that could be tidaly interacting with it. One theory that intergalaxtic gas and dust in its local galaxy group might be responsible seems to have been replaced by a direct collision/absorption of another sizeable galaxy. It also has strong star formation throughout. [Text adapted from various WEB]
