The first image of a nearby black hole has been released, which may contain 43 million suns – the first image of a black hole in the Milky Way galaxy tstr.

Highlights of the story

  • Is at the center of the galaxy
  • Taking pictures was hard work
  • It is 27 thousand light years away from the Earth

Sagittarius A * is located in the center of our galaxy. The largest telescopic interpolation (VLTI) of the European Southern Laboratory (ESO) in Chile was filming the center of the galaxy. Then suddenly he saw the mysterious black hole Sagittarius A * (Sagittarius A *) in the middle. Knew for a few seconds, then disappeared.

The largest telescope interferometer is one of the finest optical space laboratories in the world. There are four telescopes in it. The diameter of each is 27 feet. There are also four auxiliary telescopes with a diameter of 6 feet. These telescopes are so powerful that they can easily see objects 400 million times fainter than our visible objects in space.

The picture of this black hole is taken as follows

Interferometry is a technique with which light data obtained from four telescopes can be used to create a complete picture or video. The picture of the Sagittarius A * black hole in the galaxy is a clearer picture than ever before.

Julia Statler, a graduate researcher at the Max Planck Institute for Astrophysics in Germany, says VLTI has given us a wonderful picture. These are the best pictures taken in the depths of space. We marvel at the detail of these images. Also available here is a picture of the stars orbiting the black hole.

A black hole detected by the motion of stars

The power of the telescope can be deduced from the fact that the Sagittarius A * black hole in the center of the galaxy emits no light. Hard to see directly. Scientists were able to identify the black hole and photograph it due to the light and motion of the stars around it.

Reinhard Jensel, director of the Max Planck Institute for Extraterrestrial Physics and winner of the Nobel Prize in Physics in 2020, said that we have seen stars orbiting Sagittarius A *. In this way the gravitational force of the black hole can be estimated. This black hole in space is very close to our Earth.

We conducted this study between March and July this year. The Sagittarius A * black hole was found to be large enough to contain 43 million suns. It is about 27 thousand light years away from the Earth. These two figures are considered to be very accurate compared to the calculations made so far.
