'The Independent' reports that NASA's Webb Space Telescope has made the most distant detection of merging black holes. Two gigantic black holes and the galaxies that they stood at the center of merged together just 740 million years after the universe was formed in the Big Bang. One of the black holes is a staggering 50 million times larger than our Sun, and the other is believed to be a similar gigantic size. Astronomers have long wondered how supermassive black holes are so big. Lead author Hannah Ubler of the University of Cambridge says the findings suggest that mergers like this ancient example show how black holes are able to grow so rapidly. According to Ubler, the latest Webb discovery also suggests that black holes have been merging since the "cosmic dawn". "Massive black holes have been shaping the evolution of galaxies from the very beginning.", Hannah Ubler, lead author from the University of Cambridge, via 'The Independent'. In 2021, NASA launched Webb, intended to replace the Hubble Space Telescope. Webb is the largest and most powerful observatory ever launched into space. The joint U.S.-European project surveys the universe from a vantage point located about 1 million miles away from Earth
