ESA/Hubble & NASA

Monday, January 30, 2017: Galaxy NGC 4861 lies 48 million light-years away from Earth in the constellation Canes Venatici, also known as the Hunting Dogs. Frederick William Herschel, a renowned German-British astronomer, discovered it in 1785, but astronomers have yet to decide on a classification for this oddly shaped galaxy. It has the physical properties of a barred spiral galaxy, but its comet-like tail of shimmering stars give it a shape more consistent with an irregular dwarf galaxy. — Hanneke Weitering
