1 giorno fa · A team of astronomers from Stockholm University looked at later images of the Hubble Ultra Deep Field and found changes in brightness among some galaxies. These changes are attributed to black hole variability – like flickering holiday lights. The result is that they found more black holes in the early universe than has previously been reported.
1 giorno fa · Sep 17, 2024. Article. With the help of NASA's Hubble Space Telescope, an international team of researchers led by scientists in the Department of Astronomy at Stockholm University has found more black holes in the early universe than has previously been reported. The new result can help scientists understand how supermassive black holes were ...
1 giorno fa · In order to gain a complete picture of the link between galaxy and black hole evolution, the researchers used Hubble to survey how many black holes exist among a population of faint galaxies when the Universe was just a few percent of its current age. Initial observations of the survey region were re-photographed by Hubble several years later.
1 giorno fa · In principle, a primordial black hole's gravitational pull "could produce wobbles in the orbits of objects in the solar system that are big enough for us to measure." The scientists ended up ...

10 set 2024 · Two telescopes have spotted the closest pair of supermassive black holes to date. The duo, only about 300 light-years apart, were observed in different wavelengths of light using NASA’s Chandra...
3 giorni fa · Sagittarius A* in the constellation of Sagittarius. The black hole is marked with a red circle within the constellation of Sagittarius (The Archer). This map shows most of the stars visible to the unaided eye under good conditions. The diameter of Sagittarius A* is smaller than the orbit of Mercury.
