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

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

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 ...

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 ...

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 ...

(CNN) — 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 ...

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 ...
