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

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 ...

Betelgeuse is one of the weirdest stars in the sky, but astronomers can now explain one of its most enduring mysteries. A small companion star has been confirmed, revealed by the wake it leaves as it ...

When Betelgeuse finally collapses, the star – currently a red supergiant – will likely shine as brightly as the Moon in the sky for about two weeks, and be visible during the daytime for 6-12 months ...

After long speculation, a team of astrophysicists from NASA published their research, reporting that Betelgeuse, the 10th brightest star in our night sky, is orbited by a very close companion star now ...

For years, scientists were dumbfounded by the unusual changes in the brightness of Betelgeuse.

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

In a groundbreaking revelation, astronomers utilizing NASA’s Hubble Space Telescope have uncovered the influence of a newly identified companion star, Siwarha, on the gas surrounding the iconic red ...

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 ...
