Webb data, however, has revealed the galaxy is much more distant than the cluster, at 13.2 billion light-years from Earth, when the universe was only 3% of its current age.<\/p>\n Then over two weeks of observations with Chandra showed the presence of intense, superheated, X-ray emitting gas in this galaxy \u2013 a trademark for a growing supermassive black hole. The light from the galaxy and the X-rays from gas around its supermassive black hole are magnified by about a factor of four by intervening matter in Abell 2744 (due to gravitational lensing), enhancing the infrared signal detected by Webb and allowing Chandra to detect the faint X-ray source.<\/p>\n This discovery is important for understanding how some supermassive black holes can reach colossal masses soon after the big bang. Do they form directly from the collapse of massive clouds of gas, creating black holes weighing between about 10,000 and 100,000 Suns? Or do they come from explosions of the first stars that create black holes weighing only between about 10 and 100 Suns?<\/p>\n \u201cThere are physical limits on how quickly black holes can grow once they\u2019ve formed, but ones that are born more massive have a head start. It\u2019s like planting a sapling, which takes less time to grow into a full-size tree than if you started with only a seed\u201d, said Andy Goulding of Princeton University. Goulding is a co-author of the Nature Astronomy paper and lead author of a new paper in The Astrophysical Journal Letters that reports the galaxy\u2019s distance and mass using a spectrum from Webb.<\/p>\n Bogdan\u2019s team has found strong evidence that the newly discovered black hole was born massive. Its mass is estimated to fall between 10 and 100 million Suns, based on the brightness and energy of the X-rays. This mass range is similar to that of all the stars in the galaxy where it lives, which is in stark contrast to black holes in the centers of galaxies in the nearby universe that usually contain only about a tenth of a percent of the mass of their host galaxy\u2019s stars.<\/p>\n The large mass of the black hole at a young age, plus the amount of X-rays it produces and the brightness of the galaxy detected by Webb, all agree with theoretical predictions in 2017 by co-author Priyamvada Natarajan of Yale University for an \u201cOutsize Black Hole\u201d that directly formed from the collapse of a huge cloud of gas.<\/p>\n \u201cWe think that this is the first detection of an \u2018Outsize Black Hole\u2019 and the best evidence yet obtained that some black holes form from massive clouds of gas,\u201d said Natarajan. \u201cFor the first time we are seeing a brief stage where a supermassive black hole weighs about as much as the stars in its galaxy, before it falls behind.\u201d<\/p>\n The researchers plan to use this and other results pouring in from Webb and those combining data from other telescopes to fill out a larger picture of the early universe.<\/p>\n NASA\u2019s Hubble Space Telescope previously showed that light from distant galaxies is highly magnified by matter in the intervening galaxy cluster, providing part of the motivation for the Webb and Chandra observations described here.<\/p>\n The paper describing the results by Bogdan\u2019s team appears in Nature Astronomy, and a preprint is available online<\/a>.<\/p>\n The Webb data used in both papers is part of a survey called the Ultradeep Nirspec and nirCam ObserVations before the Epoch of Reionization (UNCOVER). The paper led by UNCOVER team member Andy Goulding appears in the\u00a0Astrophysical Journal Letters<\/a>. The co-authors include other UNCOVER team members, plus Bogdan and Natarajan. A detailed interpretation paper that compares observed properties of UHZ1 with theoretical models for Outsize Black Hole Galaxies is forthcoming.<\/p>\n NASA\u2019s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory\u2019s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.<\/p>\n The James Webb Space Telescope is the world\u2019s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.<\/p>\n Read more from NASA\u2019s Chandra X-ray Observatory.<\/a><\/p>\n For more Chandra images, multimedia and related materials, visit:<\/p>\n https:\/\/www.nasa.gov\/mission\/chandra-x-ray-observatory\/<\/a><\/p>\n Megan Watzke<\/a> Jonathan Deal<\/a>
