Optical proof of a tiny companion orbiting supergiant star Betelgeuse is hard to come by. Hubble just spotted new evidence.

Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner rather than later. That's because it's a ...

What makes the star remarkable is its location. Siwarha appears to orbit so close that it never leaves Betelgeuse’s ...

Ignoring interference from the occasional dusty sneeze, Betelgeuse's light seems to vary according to two distinct cycles.

The bizarre dimming patterns of Betelgeuse, an enormous red supergiant star in the constellation Orion, have bewildered astronomers for decades. Now, researchers are closer than ever to proving that a ...

NASA’s Hubble data shows a wake of dense gas around Betelgeuse, offering the clearest proof yet of a long-suspected companion ...

Astronomers at the Center for Astrophysics | Harvard & Smithsonian have uncovered direct evidence that the red supergiant ...

Researchers found evidence that a companion star may be influencing Betelgeuse, explaining why the star’s brightness changes over time.

For years, we looked at Betelgeuse waiting for the end. When the "Great Dimming" happened in 2019, the world held its breath, ...

PHOENIX — Like a motorboat doing doughnuts in a lake, Betelgeuse’s companion star leaves a wake in the giant star’s atmosphere. Signs of the smaller star’s trail around the red supergiant are the best ...

Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. Using nearly eight years of ...
