Unique galaxies. Messier 104 - the Sombrero Galaxy.

Outer space is very different from the conditions in our own cozy atmosphere. Massive objects of incredible mass affect each other with gravitational force. Without friction, these objects engage in a never-ending dance around their larger counterparts. This leads to many interesting formations of galaxies, one that's worth particular attention is the so-called "Sombrero" galaxy.

It is called the Sombrero galaxy, because, quite obviously, it resembles a sombrero. But why does it have such a distinct form? Other galaxies are much more widespread, aren't they? Well, what you see is just a lot of cosmic dust and gas. Their temperature is low, so the gas is quite visible. Presumably, stars and planets form from these clouds of matter floating around in Messier 104. Besides, this galaxy has a lot more objects in it than others.

Sure, it looks cool, that's what we amateurs see. But this galaxy is of much interest to professional scientists alike. Every galaxy has an object of humongous mass in its center, that keeps all the solar systems inside and prevents them from flying out into all directions. The Sombrero galaxy is no exception. Or perhaps it is? In its center lies, what is called a Supermassive black hole. This was proven by observation, as researchers found out that for the stars to rotate that fast, an object of mass, equal to 1 billion Suns, has to exist.

All that and it's relatively close - 30 million light-years. It can be seen with an amateur telescope, in the Virgo constellation.
