A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical supernova, putting it ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...
