Black holes have been spotted spitting up remnants of stars years after gobbling them up. AdvertisementAdvertisementSince then, the collaborators have been turning their instruments to monitor 24 black holes for years on end. In another two of the cases, Cendes noticed the black holes peaking, then fading, then turning on again. Everything we know about accretion disks may be wrongThe findings could mean we need to rethink how black holes swallow up stars, Cendes said. The new findings suggest astronomers will have to rethink the relationship between stars and black holes.

NASA space telescopes detected the brightest explosion ever recorded. Images show the faint object erupting with powerful gamma rays. About 1.9 billion years ago, a dying star collapsed, exploding in a powerful burst of gamma rays that careened toward Earth. Images taken in visible light by Swift’s Ultraviolet/Optical Telescope show how the afterglow of GRB 221009A (circled) faded over the course of about 10 hours. It could be decades before another gamma-ray burst this bright appears again.
