While two teams have ideas about what happened to yellow supergiant M31-2014-DS1, ultimately, it remains a mystery.

Red supergiant stars represent a pivotal phase in the late-stage evolution of massive stars. Betelgeuse, one of the nearest and most studied red supergiants, offers a unique opportunity to explore a ...

Astronomers have observed what they believe to be a never-before-seen companion star orbiting Betelgeuse, a pulsating red supergiant star in the shoulder of the Orion constellation. One of the best ...
