A record-breaking X-ray flash may reveal the birth of a magnetar

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way to find these extreme cosmic m
