AI Summary

Astronomers have been monitoring the distant star AT 2016blu, located roughly 29 million light‑years away, for a decade because its activity suggested an imminent supernova. New research shows the star’s outbursts are not caused by an impending explosion but by a previously unseen companion influencing its behavior. AT 2016blu is an enormous star, about 33 times the mass of the Sun, a size that normally predicts a spectacular supernova at the end of its life. The findings shift expectations from a near‑term stellar death to a binary interaction driving the observed variability.
