Astronomers link mysterious cosmic flashes to collisions of dead stars

For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent encounters may also reveal themselves through X-ray flashes lasting several minutes. A new study published in Science Bulletin provides evidence for this connection, suggesting that merging neutron stars could be hiding among cosmic flashes whose origins have remained uncertain.
