Betelgeuse, one of the largest stars ever discovered, is reaching the end of its life. In the coming centuries or perhaps even right now it could explode into a supernova visible even during the day.

The yearslong dimming and brightening pattern of the huge star Betelgeuse (don’t worry—that’s just the second time we’ve said it!) may be due to a much tinier star orbiting the red supergiant, a team ...

On February 21st and 22nd, observations of red giant stars (Betelgeuse and Aldebaran), the asteroid Eunomia near the star Elnath, and nearby open clusters (NGC 1746, NGC 1802, Pleiades, and Hyades) ...

Betelgeuse's brightening and dimming over the years convinced some that it could be close to becoming a supernova. However, a new study suggests that these unexplained changes are due to a companion ...
