Newswise — Using new observations from NASA’s Hubble Space Telescope and ground-based observatories, astronomers tracked the influence of a recently discovered companion star, Siwarha, on the gas ...

After more than three decades of trailblazing discoveries, NASA’s Hubble Space Telescope has done it again. Combining fresh Hubble observations with data from ground-based observatories, astronomers ...

For more than a century, Betelgeuse has looked like a star with a secret. It swells and fades on a six-year rhythm that never quite made sense. The star, about 650 light-years away in space, is old, ...

Astronomers have discovered a companion star in an incredibly tight orbit around Betelgeuse, using the NASA-NSF-funded ‘Alopeke instrument on the Gemini North telescope. Betelgeuse, one of the most ...

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 ...

This illustration plots changes in the brightness of the red supergiant star Betelgeuse, following the titanic mass ejection of a large piece of its visible surface. The escaping material cooled to ...

Learn how Betelgeuse's atmosphere has been altered by its companion star, which has left behind a trail of expanding gas. There are times when the red supergiant star Betelgeuse looks slightly amiss, ...

Newswise — Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume, spanning a radius around 700 times that of the Sun. Despite ...
