What is the shooter and*?

shooter A* (pronounced "A-Star") is an area in the middle of our galaxy, approximately as wide as Pluto orbit, containing 3.7 million solar materials. It is located near the Galactic Center and astronomers are suspicious as a supermassive black hole that serves as a center of gravity for the whole galaxy. The shooter A* is closely orbited by the least dozen stars whose trajectory was used to estimate its mass. It can even be orbited by the first observed black hole of the middle matter, GCIRS 13E, which is estimated to be 1,300 solar materials. So, while black holes like a shooter and* are very massive when you count the huge area of ​​the event horizon, estimated at 6.25 light hours (45 AU) or about 4.2 billion miles, the average hole density is no greater than the air density! Llar-Mass holes have a much greater density behind their event horizon.

Sagittarius and* are located approximately 25,000 light -years, or half a galactic radius in the center of the Galaxy. ProbablyIt soon created in the history of the galaxy. We observe supermassive black holes such as shooter and* in the process of creating in other very distant galaxies. These phenomena are called yeast and Blazars.

Because the central singularity in the supermassive black hole is located so far from the horizon of the event, the astronaut would not experience spaghetizing up to the deep hole. The inside of the black hole would be a strange place - with a light orbiting a fast speed, you would be constantly treated with a recurring blur of the objects in its grip. At first, the light from outside would look like just a hemisphere, with darkness behind, the pachamisphere would gradually shrink, became a small circle and finally a point. Falling into the black hole would not be fun!
