Betelgeuse has been a favorite among amateur astronomers for many years. However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion ...

Betelgeuse has a radius of approximately 900 times that of our Sun. If the Sun was this size, its surface would nearly reach Jupiter. Betelguese’s surface.

Betelgeuse, one of the brightest stars in the sky in the constellation Orion, has long puzzled astronomers due to its history of dimming and brightening, sometimes unexpectedly. Now a new preprint ...

Now a new preprint study suggests that Betelgeuse could actually be two stars, revealing the second star—nicknamed Betelbuddy—to be roughly two solar masses.

Betelgeuse has a sequel — in the form of a companion star that's about the same mass as the sun, orbiting it about once every 2,100 days.

Betelgeuse has a radius of approximately 900 times that of our sun. If the sun was this size, its surface would nearly reach Jupiter. Betelguese’s surface.

A new unpublished study is making waves on the internet, claiming that one of the brightest stars in the night sky might die in a spectacular explosion within our lifetime.

Betelgeuse, one of the biggest and brightest stars in the night sky, will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.

Scientists studying the star Betelgeuse have determined that it’s actually roughly 25% closer than previous estimates. The star is also slightly smaller than scientists assumed, though it still ...

Joyce’s team posited that Saio’s team used an incorrect radius for Betelgeuse in making their claims, and the way they modeled the star ultimately yielded an inaccurate (that is to say, too ...

Betelgeuse— the star and not the slimy, suit-wearing demon—is one of the most celebrated celestial objects in the night sky. Found in the constellation Orion, Betelgeuse is extremely bright, ...
