The only supernova to have been recorded here was in 1885 and was observed by Ernst Hartwig. Simon Marius was the first to observe this through a telescope, and William Herschel noted a fairly reddish hue in its core. In 1764, Charles Messier cataloged this as object M31. Approximately 2.5 million light years away, this largest object of the Local Group is on a collision course with the Milky Way. For 10 points, identify this nearest spiral galaxy to our own.
