Astronomers have made a groundbreaking discovery that could revolutionize our understanding of the giant red supergiant Betelgeuse. A small companion star, affectionately named the ‘Betelbuddy’, has ...

Could the giant star Betelgeuse have a buddy? A Betelbuddy? Betelgeuse, the second-brightest star in the constellation Orion, is a giant star whose strange dimming has sparked debate over when it will ...

Betelgeuse is one of the brightest stars in the night sky. A brilliant red star beaming through our night sky is Betelgeuse, an aging supergiant on the shoulder of the Orion constellation. The timing ...

NASA’s Hubble and Chandra telescopes reveal Betelgeuse’s hidden companion, “Betelbuddy,” reshaping what we know about binary ...

Betelgeuse, 650 light years away, may be nearing the end of its fuel, meaning its supernova could light Earth’s skies as bright as the full moon.

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 ...

The 10th-brightest star in the night sky, Betelgeuse, may not be on the brink of exploding as a supernova, according to a new study of the star’s brightening and dimming. Instead, recent research ...

The stars in the night sky, as we typically perceive them, are normally static and unchanging to our eyes. Sure, there are variable stars that brighten and fainten, but most of those do so ...

Astronomers have confirmed the existence of a companion star in a tight orbit around Betelgeuse, resolving a long-standing mystery about the star’s varying brightness. Reading time: Reading time 2 ...
