Type Galaxy Constellation Virgo Magnitude 9.5 Apparent size 9′ × 4′ You need a small telescope Known as Messier M104 Dreyer NGC 4594 Physical Distance 31 million light years Stars about 2,000 globular clusters orbit it More information about Sombrero Galaxy The Sombrero Galaxy is a spiral seen from the side, tilted only six degrees off edge-on, so it looks like a bright line with a bulge (the galaxy core) in the middle rather than a spiral. A band of dust runs along the line and cuts across the bulge as a dark stripe, which gives it its name: it makes it look like a hat with a flat brim and rounded crown. Around it are nearly 2,000 globular clusters, dense balls of very old stars, against about 150 for our own galaxy. At the centre is a black hole around a billion times the mass of the Sun. History Discovered 1781, Pierre Mechain Messier was hunting comets. He compiled his list between 1758 and 1781 as a register of things that look like comets but are not. That's why the objects on it have nothing in common beyond being fuzzy and staying put. Dreyer compiled the New General Catalogue in 1888, mostly from the sweeps William and John Herschel made of the sky, and numbered its 7,840 objects in order of right ascension. where it is tonight: skymap.sh/Sombrero Galaxy
