WOH G64, a red supergiant star 1,500 times the Sun's radius, may imminently explode as a supernova or collapse into a black hole, according to a study in *Nature Astronomy*. Located 165,000 light-years away in the Large Magellanic Cloud, the star’s rapid evolution—triggered by a 2014 color shift—has baffled scientists. Researchers suggest its transformation into a yellow hypergiant resulted from either a companion star stripping material or intrinsic eruptions lasting decades.

Either scenario is rare, with only tens of confirmed yellow hypergiants known. The star’s fate remains uncertain, but its demise—whether via supernova, black hole formation, or collision with its binary partner—will occur within hundreds to thousands of years. This event could reshape understanding of stellar evolution for massive stars (23–30 solar masses).
