M104/NGC4549 | Sombrero Galaxy | LRGB
The incredible glare emitted by the Sombrero Galaxy, catalogued as M104 or NGC4549, lights space for many thousands of light years beyond its central core. This galaxy lies in the constellation of Virgo, being some 31 million light years distant from Earth. This galaxy is approximately one quarter to one third the size of our own Milky Way Galaxy [M104: approximately 50,000 light years diameter].
This galaxy also has a striking dust lane that heavily contrasts against the bright glow. Rolf Olsen has previously defined in his excellent annotated image summary of M104 that the Sombrero Galaxy has a large number of orbiting globular clusters, estimated to be in the number of 1,200 to 2,000. These globular clusters are a spherical collection of a massive number of stars held tightly in formation by gravity.
Hope you enjoy this beautiful galaxy - thank you for looking.
