Centimeter-sized pebbles have been detected in protoplanetary discs using e‑MERLIN, filling in a critical phase of planet ...

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 ...

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.

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— 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 ...

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 ...

Betelgeuse, or Alpha Orionis (α Ori), is a red supergiant in the Orion constellation. With a radius about 764 times that of the Sun, it’s one of the largest stars visible to the naked eye.

Simulation of Betelgeuse's boiling surface. (Jing-Ze Ma et al., The Astrophysical Journal Letters, 2024) Interestingly though, the team conclude that the most likely explanation for the long term ...

Newly Released Betelgeuse Simulation Shows It As A Boiling, Bubbling Ball Red giant stars are not perfect spheres, but ever-changing objects.

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.
