Photos confirm what’s at the center of our galaxy – RT World News

Astronomers have confirmed that the object in the center of our galaxy is a black hole and photographed it

Astronomers have confirmed that the supermassive object at the center of the Milky Way galaxy was actually a black hole and captured its first images using a global network of telescopes. A team of researchers known as the Collaboration Event Horizon Telescope (EHT) unveiled the images at multiple press conferences on Thursday.


Researchers have solved the mystery of black holes

Known as Sagittarius A, the object in the center of the Milky Way – “Invisible, compact and very hugeThis was stated in a press release issued by the European Southern Observatory – which has long been suspected of being a black hole. However, images created by linking a global network of radio telescopes provide direct evidence of this hypothesis.

Images show a dark central “Shadow“Surrounded by a luminous ring made up of bright gas, they produce light curved by the strong gravity of a black hole. The mass of the object is four million times that of the Sun, and it is 27,000 light-years away from our planet.

The visuals were recorded by combining eight radio observatories around the world to create what the researchers described. “A single ‘Earth-size’ virtual telescope“, Which was used to observe Sagittarius A at multiple nights in 2017.

EHT, which includes more than 300 researchers from 80 organizations, previously released black results M87 at the center of the distant Messier 87 galaxy, revealing the results in 2019. Sagittarius A is very close, but more than 1,000 times smaller and less massive. However, it was significantly more difficult to capture images of the gases surrounding the Milky Way’s black hole during rapid orbits, according to EHT scientist Chi-Quan Chan.A puppy quickly chases its tail and tries to take a clear picture

Nonetheless, the final product appears to bear considerable resemblance to his great cousin, M87, vice-president of the Science Council at EHT, best Mark Markf, who sees the similarity as evidence that “General relativity controls these objects closely, and any differences we see farther away must be due to differences in the elements surrounding the black hole.

Researchers have used data from both black holes to test hypotheses about mysterious objects, from their effects on gravity to how gases behave around them, a process that is not poorly understood but which astronomers believe played a role in how galaxies are formed. Observes And increases over time.

Along with the photographic results were six research papers published in the Astrophysical Journal Letter covering various aspects of the discovery, from the imaging process to the morphology of black holes.
