South Africa's MeerKAT telescope first detected the burst on March 4, 2024; the study was published October 8 in Science.\n\nThe light left its source when the universe was about three billion years old, more than doubling the distance of the previous record holder. Webb showed the host galaxy is small, metal-poor and forming many stars.\n\nResearchers suggest the burst may have come from a magnetar, a highly magnetized stellar core left behind by a supernova. Finding such bursts at great distances lets astronomers use them to probe matter between galaxies in the early universe."}}
