A new video released by NASA shows how the transition from the nearest black star to Earth and the stars that accompany them. The animation features 22 binary systems in the Milky Way and three neighboring galaxies, the Great Magellanic Cloud, the host of real-time black-and-white.
In the pictures it can be seen in each pair that the binary systems are formed by the stars that orbits in a black hole. In each part of the animation, the black hole is represented by a black dot in the center of the acretion disk.
The colors of the stars in the videos range from blue-white to reddish, indicating that they are five times hotter or up to 45% cooler than the sun, respectively.
According to the agency, the star was seen as having a large blue or yellowish-white face to match its size.
Another interesting detail is that the systems appear on the same physical scale, making visible differences. The orbital motion is accelerated by 22,000 times and the viewing angles are the same as we see from Earth. The black holes are presented on a scale that indicates their mass, appearing larger than they actually are.
As the material heats up the disk as it falls into the black hole, it shines brightly in light and ultraviolet, and X-rays can capture images – because of the darkness, the black can not be seen. of the glasses.
According to NASA, astronomers have not yet agreed on how the system in the middle of the video, GRS 1915, works, far farther than that separates Mercury from the sun, e.g. li.
what is the black hole
A black hole is an area in which the force of gravity is so strong that not even light can escape from it. When designed, the gravity in the region of the black hole is so strong that all matter attracted to it is compressed until it is destroyed.
Every star 20 times the size of the sun will turn into a black hole when it “dies”.
Whatever the name says, the black glow – not by themselves, but by interfering with the star friends to identify them. Therefore, astronomers observe the relationship between the celestial bodies. And the best way to do that is to look at X-rays.
A black binary hole can collect energy (to feed) its star in two ways. The first is that streams of air can flow directly from the host galaxy star to the black hole, swirling “like water flowing.”
The second is when the star solar wind pushes the object into the black hole. When matter is “used”, a large amount of energy, in the form of X-rays, is released.
Cygnus X-1, first of all
The first black hole known to scientists was Cygnus X-1, weighing 21 times the sun.
Its surface, called the “event horizon”, is about 124 kilometers long – which is considered very small for a black hole. However, the visualization sees the Cygnus X-1 larger, more in line with the black hole than its volume.
The large spheres also cover the visual imbalance created by the gravitational effects of the black matter.
