A beautiful spiral galaxy belonging to the Local Group. The Local Group is dominated by the Milky Way, Andromeda (M 31) and the Triangulum Galaxy (M 33). As the smallest member, it lies about 2.7 million lightyears away in the constellation of the same name (Triangle). Just 60.000 light-years across, the Triangular Galaxy is home to between 10 and 40 billion solar masses of stars. No bright central bulge or "bar" is visible, but it contains huge amounts of gas and dust that are rapidly forming stars.
Because of the regular spiral shape, astronomers suspect that the galaxy had no interactions with its neighbors. But that could change. M 33 is not much further from us than the Andromeda Galaxy and could be its gravitational companion on its journey to the Milky Way. The Triangulum Galaxy would be a third player in the upcoming collision between Andromeda and the Milky Way more than 4 billion years from now.
