<img src=”https://naked-science.ru/wp-content/uploads/2025/03/RunawayStarIllustration-1.jpg” alt=”A runaway star is observed to be ‘pulsating’ beyond the Milky Way’s disk”/>Astronomers are observing a star with a mass almost five times greater than the Sun, which flew out of a large spiral arm of the Milky Way tens of millions of years ago and is now moving outside the plane of our Galaxy’s disk. The object is slowly ‘pulsating’, and this is explained by its internal processes. Scientists suspect that the star accelerated during a supernova explosion in a binary system.
