Astronomers Witness Merger of 2 Black Holes From the 'Cosmic Dawn'

Astronomers Witness , Merger of 2 Black Holes, From the 'Cosmic Dawn'. '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.

The company issued a press release warning that a second launch attempt could end in catastrophe. . The statement from ValveTech President Erin Faville called for NASA to re-double safety checks and protocols. . The failed launch last week would have been the first human space flight for Boeing but was scrubbed after a faulty valve was discovered. . The Associated Press reported that the fluttering oxygen pressure-relief valve on United Launch Alliance’s Atlas rocket may have exceeded its 200,000 lifetime cycles. . The ValveTech statement questions how NASA, Aerojet and Boeing could have... . ... "qualified this valve for the mission without proper supporting data or previous history or legacy information.". According to ValveTech, this , "goes against aerospace-industry qualification protocols established by NASA."

'Initiate our scrub and recycle operation': Boeing abandons Starliner launch

Boeing called off its first astronaut launch, ferrying two NASA test pilots to the International Space Station, because of a valve problem on its Starliner capsule. But if engineers find a solution quickly, another countdown could be expected in the next 24-hours.
