NASA Telescopes Detect Earliest Active Supermassive Black Hole, Providing Clues to Cosmic Formation
Record-Breaking Black Hole in Galaxy UHZ1, Discovered Through X-rays By James Webb Space Telescope and Chandra X-ray Observatory, Challenges Existing Theories About Early Formation of Supermassive Black Holes.
- NASA's James Webb Space Telescope and Chandra X-ray Observatory have detected the most distant, active supermassive black hole, located in galaxy UHZ1, formed just 470 million years after the Big Bang.
- The black hole's existence provides key insights regarding the formation of supermassive black holes at the center of galaxies, challenging existing theories.
- Using gravitational lensing, the telescopes were able to observe the black hole in its early stage of growth, where its mass was equivalent to its host galaxy which is approximately 140 million times the mass of the sun.
- Scientists believe the black hole was born large, an estimated mass between 10 million and 100 million suns, suggesting supermassive black holes could be formed directly from a collapsing gas cloud, rather than rapid mergers of stellar-mass black holes from exploding stars.
- The detection of the young supermassive black hole could provide further understanding on the correlation between the mass of a black hole and the mass of its host galaxy, as most supermassive black holes in modern galaxies amount to only a tenth of the mass of their host galaxy.
