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 ...

A couple months back, astronomers officially confirmed the existence of “Betelbuddy,” Betelgeuse’s long-suspected companion ...

Betelgeuse is a colossal star that shines brilliantly in the constellation Orion, approximately 600 light-years from Earth. Immense and unstable, this red supergiant is in the final stages of its ...

NASA's Chandra X-ray Observatory and Hubble Space Telescope confirmed the existence of a companion star orbiting Betelgeuse, ...

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 ...

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 ...

Betelgeuse is one of the night sky's brightest stars and easily can be observed from Earth with the naked eye. Its fluctuations in brightness have long puzzled astronomers, however. Now, researchers ...

New X-ray observations reveal Betelgeuse’s mysterious companion is not a collapsed stellar remnant but a young, Sun-like F-type star orbiting the massive red supergiant.

But this orbital dance has a darker future. Over time, tidal forces continue to drain energy from Siwarha’s orbit, pulling it closer to the red supergiant. Eventually, the smaller star will spiral ...
