Black Holes were more common in the early Universe than astronomers had realized. By zooming into a relatively empty region of the sky, scientists using the orbiting Hubble and Chandra telescope have combined the deepest X-ray image ever made with some of the faintest visible light ever photographed. These 200 distant galaxies appear as they were when the universe was only about 900 million years old. Those circles indicate locations of some of the young black holes. Chandra detected very strong x-ray signals from point sources in those areas, implying that small black holes are shrouded within the massive gas clouds and star crowds of very young galaxies. Such young black holes would be similar to quasars – very bright objects powered by supermassive black holes. But these baby black holes are much smaller – about a thousand times less massive and perhaps a hundred times less bright – than the big ones in quasars. Scientists think these infant singularities will each grow perhaps 1000% larger, someday maturing into giant black holes like the ones we see today nearly 13 billion years later.” Black Holes and galaxies, it seems, may start their lives together; that’s a much earlier start for black holes than physicists thought possible until this discovery. For SDC, I’m …
New discoveries suggest that black holes and galaxies may be born together. Hubble and Chandra teams combined the deepest X-ray image ever made with some of the faintest light ever photographed.
