Abstract

The article discusses the confirmation of a lone black hole, the first of its kind identified without a companion star, located in the constellation Sagittarius. Discovered in 2022 by astronomers at the Space Telescope Science Institute, the black hole's existence was validated through observations from the Hubble Space Telescope, which revealed its mass to be approximately seven times that of the sun. This solitary black hole, situated about 5,000 light-years from Earth, was detected as it passed in front of a dim background star, causing observable gravitational effects. Future efforts to locate additional lone black holes are planned with the upcoming Nancy Grace Roman Space Telescope, set to launch in 2027. [Extracted from the article]
