A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light—an event never witnessed before. Using XMM-Newton and XRISM, astronomers caught the blast unfold in real time, revealing how tangled magnetic fields can rapidly “untwist” and hurl matter into space much like an enormous, cosmic-scale version of the Sun’s coronal mass ejections.
Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...
