(Observer Network) According to the British "Guardian" report on May 6, local time, scientists announced on the same day that they observed the black hole closest to the earth so far, which is only 1,000 light-years away from us.
On May 6, local time, the official website of the European Southern Observatory announced that a team of astronomers composed of the European Southern Observatory (ESO) and other institutes had discovered a black hole 1,000 light-years from Earth.
This black hole is located in the HD 167128 (classified as HR 6819 in the bright star catalogue) galaxy in the telescope constellation. This is a tri-star system visible to the naked eye (approximately 5.36 apparent magnitude, slightly brighter than Uranus).
Previously, astronomers had always considered HD 167128 to be a binary system. But when they used the MPG / ESO 2.2-meter telescope of the Lazia Observatory in Chile to observe and analyze the results, they found that there is another celestial body in the stellar system: a black hole.
According to scientists from the European Southern Observatory (ESO), one of the two stars is orbiting an invisible celestial body in a 40-day revolution, while the other is operating alone in a more distant place. They inferred that the black hole was formed by the collapse of the star when it "dead", and its mass is about 4 times that of the sun.
