NASA discovered a huge black hole formed 470 million years after the Big Bang, about 13.2 billion light-years away from Earth.
with the help of data from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope, scientists discovered a huge black hole formed in the early days of the Big Bang. Its mass is equivalent to the combined mass of all the stars in the galaxy.
Akos Bogdan and his team discovered the black hole in a galaxy called UHZ1 in the direction of the galaxy cluster Abell 2744, 3.5 billion light-years from Earth. However, Webb data shows that the galaxy is much farther than the cluster, actually about 13.2 billion light-years away from Earth, and was born 470 million years after the Big Bang, when the universe was only 3% of its current age.
The relevant research report has been published in the magazine “Nature Astronomy” (NaijaTechNews.com attached DOI: 2305.15458 ).

According to reports, this is the most distant black hole ever observed by humans with the help of X-rays, and it is also the oldest black hole. The black hole is in an early stage of growth never seen before. This discovery may help scientists understand how some supermassive black holes were formed in the early days of the universe.
Bogdan’s team found that the black hole was very massive when it was born. Depending on the X-ray brightness and energy, its mass is estimated to be between 10 and 100 million suns. This mass range is similar to the combined mass of all the stars in its host galaxy, which is in sharp contrast to the black holes at the centers of galaxies in the nearby universe, which typically contain only about one-thousandth of the mass of the stars in their host galaxies.
After two weeks of observations with the Chandra X-ray Observatory, scientists finally discovered the presence of intense, superheated X-ray emitting gas (a sign of a supermassive black hole) in this galaxy.
It is claimed that due to intervening matter in Abell 2744 (due to gravitational lensing), light from the galaxy and X-rays from the gas surrounding its supermassive black hole are amplified by about four times, enhancing the infrared signal detected by Webb and making money Della is able to detect weak X-ray sources.
Andy Goulding of Princeton University points out, “Once black holes form, there are physical limits on how fast they can grow, but those that are born heavier have an advantage. Like planting a sapling, the time it takes for it to grow into a full-sized tree Less than starting from seed”.
Additionally, Goulding, co-author of the Nature Astronomy paper, has published a new paper in the Astrophysical Journal Letters that reports the galaxy’s distance and mass using Webb’s spectrum.
It is worth mentioning that the huge mass of the young supermassive black hole, coupled with the number of X-rays it produces and the brightness of the galaxy detected by Webb, everything seems to be consistent with the theoretical predictions of Yale University co-author Priyamvada Natarajan in 2017 , that is, a “supermassive black hole” formed directly from the collapse of a large gas cloud.
“We believe this is the first detection of a ‘supermassive black hole’ and the best evidence yet that some black holes are formed from massive gas clouds,” Natarajan said.
