Scientists have discovered that the sombrero galaxy is unlike any other galaxy they have ever seen. It has some features that are very unusual and puzzling, and that could hint at a hidden purpose behind its existence. One of these features is the sombrero galaxy's rotation. Most galaxies spin around their axis like a top, but the sombrero galaxy does not. Instead it wobbles, like a gyroscope, with its axis tilted by 90 degrees. This means that the sombrero galaxy is not an equilibrium, and that it is experiencing some kind of external force or torque. But what could be causing this force? And what is the sombrero galaxy trying to achieve by wobbling? Another feature that baffles scientists is the sombrero galaxy's halo. A halo is a spherical region of stars and gas that surrounds a galaxy, and it is usually very faint and diffuse. But the sombrero galaxy's halo is very bright and dense, and it contains a lot of metal rich stars.
