🌀 Huge Star on the Brink? The Story of WOH G64

Astronomers may be witnessing a rare late stage in the life of one of the largest stars known in the universe — a star that might be gearing up for a spectacular finale.

🌟 What is WOH G64?
Located in the Large Magellanic Cloud, a small galaxy orbiting the Milky Way, WOH G64 is an extremely massive star — about 1,500 times wider than our Sun. It’s so large that if it were placed at the center of our Solar System, its surface would extend beyond the orbit of Jupiter.

🔄 A Dramatic Transformation
New research published in Nature Astronomy shows that WOH G64 has undergone a dramatic change in the past decade. Between 2013–2014, the star appeared to shrink and heat up, shifting from a cool red supergiant to a rarer and hotter type called a yellow hypergiant. This kind of shift is thought to be part of the final evolutionary phases for very massive stars.

🔥 Signs of an Impending Explosion?
Such transformations are theorized to happen shortly before a supernova — the explosive death of a massive star. This suggests we may be seeing WOH G64 in its last stages of life, shedding its outer layers and heating up as it nears collapse. However, the exact timeline is uncertain, and it could still be thousands or tens of thousands of years away from exploding.

🔍 Why This Matters
Astronomers rarely get to observe these late evolutionary stages in real time, especially for stars outside our galaxy. WOH G64 offers a unique chance to understand how the universe’s biggest stars live and die — and could help scientists refine models of massive star evolution and supernova mechanics.
