Join us for an exciting playthrough of "Street Fighter X Tekken," featuring the dynamic duo: Asuka and Cammy, also known as Team Betelgeuse! Watch as they take on challengers in this thrilling ...

Betelgeuse dimmed dramatically, prompting theories of an impending supernova. Instead, astronomers uncovered an even stranger ...

Betelgeuse, which shines in Orion as part of the Winter Triangle, is a huge, short-lived star that is thought to soon end its life as a supernova explosion. It is unclear whether that will happen ...

Estimates based on the mass of Betelgeuse, its rotation rate, the group of stars it was born with, and the amount of metals we can measure in the upper layers of its atmosphere, all suggest that ...

Both teams agree closely on the facts of the invisible companion. It can’t be much more than the mass of the Sun, which makes it a mere one-twentieth the mass of Betelgeuse.

In this latest study, a predicted sun-like star, perhaps up to double the mass of the sun, clears the dust out of Betelgeuse's way, making it appear brighter.

The supergiant star Betelgeuse may have a companion star that pushes light-blocking dust out of the way, causing the irregular changes observed in the star's brightness.

Meridith Joyce, an assistant professor in the University of Wyoming Department of Astronomy and Physics, was part of a research team that studied the brightening and dimming of a star known as ...

Betelgeuse, Betelgeuse! The red supergiant that marks Orion’s left shoulder may have a tiny, unseen companion. Two independent studies found evidence of a star about the same mass as the sun ...

In other words, Betelgeuse is actually two stars. This hypothesized, unknown star—excellently nicknamed Betelbuddy—is likely at least two times the mass of our Sun.

The companion star, if it exists, is roughly the same mass of our Sun, and may explain Betelgeuse’s long secondary period (LSP)—a 2,170-day (6-year) cycle during which the supergiant dims and ...
