Sombrero Galaxy

It has a bright center, an unusually large central area, and a visible dust lane in its outer disk, which is viewed almost sideways. The dark dust lane and the central area give it the look of a sombrero hat (that is how it got its name). Astronomers first thought the halo was small and light, suggesting it was a spiral galaxy; but the Spitzer Space Telescope found that the halo was actually much larger and more massive, suggesting it is a giant elliptical galaxy.
