Summary

Story summary

WOH G64 has shifted from a red supergiant to a yellow hypergiant, shedding layers.
The change was noted in 2014 and may arise from a companion-star interaction or a pre-supernova 'superwind' phase.
The star lies in the Large Magellanic Cloud, measures 1,500 solar radii, and is under 5 million years old.
A study led by Gonzalo Muñoz-Sanchez notes the transformation could provide insights into massive-star evolution and its eventual explosion.
