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

The dimming of Betelgeuse seen at the end of 2019 and the start of 2020 explained — the red giant star “sneezed.” Betelgeuse dimmed in the final few months of 2019, perplexing both professional and ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Artist's concept shows the red supergiant star Betelgeuse and an orbiting companion star. The companion, which is orbiting ...

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 ...

Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner rather than later. That's because it's a red supergiant on the verge of becoming a supernova and there hasn't been ...

Betelgeuse first drew attention in late 2019 when the star, which glitters like a red gem in the upper-right shoulder of Orion, experienced an unexpected darkening. The supergiant continued to grow ...

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 ...
