Story summary

Astronomers at Chalmers University of Technology discovered a massive gas and dust bubble around the red supergiant star DFK 52, the largest in the Milky Way.
The bubble, equivalent to the Sun's mass, formed from a stellar eruption approximately 4,000 years ago.
DFK 52 is a potential candidate for the next supernova, with further observations planned.
The study, published in Astronomy and Astrophysics, emphasizes the role of red supergiants in stellar evolution.
