Pierre Mechain discovered the Sombrero Galaxy in 11May 1781. He described the object in a May 1783 letter . William Herschel independently discovered the object in 1784 and additionally noted the presence of a "dark stratum" in the galaxy's disc, what is now called a dust lane.Later astronomers were able to connect Méchain's and Herschel's observations.
This galaxy has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which is viewed almost edge-on.
It’s dark dust lane and the central bulge give it the appearance of a beautiful sombrero hat (giving it this name). Astronomers initially thought the halo was small and light, indicative of a spiral galaxy; but the Spitzer Space Telescope found that the halo was significantly larger and more massive than previously thought, it indicates that it’s a giant elliptical galaxy.
