A new video released by NASA shows how the dynamics between the black hole near Earth and the accompanying stars look. The animation consists of 22 pairs of systems located in the Milky Way and our neighboring galaxy, the Great Magellanic Cloud, which the host identified a black hole with many stars.
In the picture it is possible to see in each pair that binary systems are formed by a star rotating in a black hole. In each animation section, a black hole is represented by a black drop in the center of the extension disk.
The star colors in the video range from blue-white to red, indicating five times warmer temperatures or up to 45% cooler than the Sun, respectively.
According to the astronomical organization, the star is depicted as a white or yellow circle with a size commensurate with its size.
Another explanation is that the systems look at the same physical level, showing diversity. The motion of the orbit is 22,000 times faster and the viewing angles are the same as we see from Earth. Black holes are presented with scales that reflect their masses, appearing larger than they really are.
When the material heats on the disk falls into a black hole, it glows in the visible and ultraviolet light, and X-rays can take pictures – due to the darkness, black holes cannot be seen through a telescope.
According to NASA, astronomers have not yet reached an agreement on how the central video system, GRS 1915, works. , a distance greater than the one separating Mercury from the Sun, for example.
what a black hole is
A black hole is an area where gravity is so strong that even light cannot escape. Once formed, gravity in the area of the black hole is so strong that all objects of interest are suppressed to the point of destruction.
Every star that has 20 times the mass of the Sun will turn into a black hole “when it dies”.
Despite what the name implies, the black hole shines – not alone, but by interacting with a fellow star to discover them. Thus, astronomers see the connection between these celestial bodies. And the best way to do that is to look at X-rays.
A black hole can collect energy (feed) its star in two ways. The first is that a stream of gas can flow directly from a galaxy star into a black hole, circling “like water under a pipe.”
The second is when the solar wind forces push the material into a black hole. When “used”, large amounts of energy, in the form of X-rays, are released.
Cygnus X-1, first of all
The first black hole known to researchers is the Cygnus X-1, which is 21 times heavier than the Sun.
Its surface, called the “incident range”, is 124 km long – which is considered too small for a black hole. However, the image shows the Cygnus X-1 being larger, more proportional to the size of the black hole than its volume.
Larger spheres also cover the visible distortion produced by the gravitational effects of black holes.
