Cosmic giant on the brink: a star may be primed for a supernova
New research finds that WOH G64, one of the universe’s largest stars in the Large Magellanic Cloud, shifted from a red supergiant to a yellow hypergiant around 2014, likely shedding mass as its core contracts and heats. If confirmed, this rapid evolution could herald an imminent supernova, offering a rare chance to observe a star dying in real time.
