Scientists have described how the first images will look like a black hole
It is assumed that the center of our Milky Way lies a giant black hole Sagittarius called A, but just to see it with the help of modern equipment we can not. Recently, astronomers have suggested, how it will look in the photographs - a new technology that allows you to see our "neighbor", will soon be available.
Astronomers said that the black hole in the photograph - or rather, its borders - will take the form of a crescent, rather than a bubble, as it was supposed earlier.
By themselves, black holes, of course, are invisible because not even light can escape their gravitational clutches. However, the boundaries of the black hole - the very point of no return, which is called the "event horizon" - should be distinguished due to radiation from matter falling into a black hole.
These photos will soon become available to astronomers as being built for this purpose telescope with the same name - "Event Horizon" - will soon be ready. This telescope will be the first device to solve problems of this magnitude. The researchers believe that the first image they will receive in the next five years.
"Event Horizon" has already been tested once to collect preliminary data about this interesting object in our galaxy. Based on these studies and concluded that the boundaries of the crescent-shaped. Since the substance, before getting inside, while revolving around a black hole, one side of the "drive" is shifted toward the Earth, and the light becomes brighter because of a process called the Doppler effect. The other side, which reflects the gas, because the effect will look darker.
In the center we see the crescent dark circle, which is called the shadow of a black hole - an object of incredible density, where the distortion of space and time.
The ultimate goal of astronomers - to use the photo for calculating the weight of the supergiant Sagittarius A in the center of the Milky Way.
