NASA has released a video of the most famous black holes.

A new video released by NASA shows how the dynamics between the nearest black holes to the Earth and its adjacent stars look like. There are 22 binary systems in the animation located in the Milky Way galaxy, the Milky Way galaxy, the host of which has confirmed massive black holes in the stars.

In each pair of images it is possible to see that the binary system is made up of a star orbiting a black hole. In each part of the animation, the black hole is represented by a black dot located in the center of the action disk.

The colors of the stars in the video range from bluish white to reddish, indicating that the temperature is five times higher than the sun, or up to 45% cooler, respectively.

According to the space agency, the star is represented as a blue or yellow white sphere, the size of which corresponds to its size.

Another explanation is that systems appear on the same physical scale, demonstrating diversity. Orbital motion is 22,000 times faster and the viewing angles are the same as we see from Earth. Black holes are presented on a scale that reflects the people they belong to, who appear to be larger than they really are.

As the material falls into the black hole, the disk heats up, shines in visible and ultraviolet light, and is able to take X-ray images – because of the darkness, the black holes cannot be seen through binoculars.

According to NASA, astronomers have not yet been able to agree on how the GRS 1915 system at the center of the video works, for example, the distance that separates Mercury from the Sun.

What is a black hole?

A black hole is a region in space where the force of gravity is so strong that light cannot escape from it. Once formed, the gravity in the area of ​​the black hole is so strong that all the matter attracted to it shrinks until it is destroyed.

Every star that is 20 times the mass of the Sun will “die” into a black hole.

Despite the name, black holes shine – not on their own, but by interacting with a fellow star to detect them. Therefore, astronomers observe the relationship between these celestial bodies. And the best way to do that is to look at X-rays.

A binary black hole can store energy in its star in two ways. The first is that a stream of gas can flow directly from a host galaxy’s star to a black hole, rotating “like water down a drain.”

The second is when the star’s solar winds push matter into a black hole. When the substance is “consumed”, a lot of energy is released in the form of X-rays.

Cygnus X-1, first

The first black hole known to researchers is the Cygnus X-1, which weighs 21 times as much as the Sun.

Its surface, called the “Event Horizon”, is about 124 kilometers long – which is considered too small for a black hole. However, the concept shows that the Cygnus X-1 is so large that the mass of the black hole exceeds its size.

Larger circles also hide the visible distortions caused by the gravitational effects of black holes.
