Not long ago, the James Webb Space Telescope (JWST) peered into Cosmic Dawn, the cosmological period when the first galaxies formed less than one billion years after the Big Bang. In the process, it discovered something rather surprising. Not only were there more galaxies (and brighter ones, too!) than expected, but these galaxies had supermassive … Read more
The most detailed map of the universe ever created using gravitational waves could reveal hidden black holes, merging supermassive black holes and even the large-scale structure of the cosmos. The study, conducted by a team led by astronomers from Swinburne University of Technology, also presented the largest-ever galactic-scale detector of gravitational waves, which are basically … Read more
Scientists believe that at the heart of all large galaxies lurk supermassive black holes, cosmic titans with masses equivalent to that of millions or even billions of suns. Yet some black holes exceed even these monstrous masses to become “ultramassive black holes.” The most massive black hole that we are currently aware of is Phoenix … Read more
