Astronomers have discovered a black hole 1,000 light years before Earth. It was found in a system called HR 6819, in the constellation Telescopeium.
The discovery was published in the journal Astronomy and Astrophysics.
When viewed through the telescope, the system resembles a single bright star, but light emitted from the system before shows that it has two starts.
After a detailed analysis of the expected data, astronomers found that a black hole four times larger than our Sun and just 1,000 light years from Earth.
“We felt that we could not describe what we can see with only two stars,” said astronaut Dittrich Bad, an Emeritus at the European Southern Observatory (ESO).
“One of the stars is growing from time to time, with a period of 40 days. And the only way to understand that period and very large [velocity] Five times the sun with a mass of 60 km per second was supposed to have another massive body which, however, is not visible, ”he said.
Bade said that this black hole is ‘really black’, saying that the star is ‘not very big’, and loses a lot of gas which turns it black. “This may also be the first time [black hole of this kind],” he said.
He also said that the system HR 6819 and its stars can be seen with the naked eye. “If you really want to see it overhead, you need to be on the southern tip of South America,” Bade said.
A black hole is an object formed by the gravitational collapse of a massive star.
