Our results say Betelgeuse only extends out to two-thirds of that, with a radius 750 times the radius of the sun,” Dr. László Molnár, co-author of the study, said in a statement.

Found in the constellation Orion, Betelgeuse is extremely bright, especially considering that it’s roughly 650 light-years from Earth (though, it does have a radius 1,000 times bigger than the Sun).

In a groundbreaking and terrifying announcement, NASA’s Chief Scientist has revealed some alarming news about Betelgeuse, one ...

The red supergiant Betelgeuse, a colossal star in the Orion constellation, experienced a massive stellar eruption in 2019, the likes of which have never been seen, according to astronomers. The ...

But unlike the brightening Betelgeuse, that star has been consistently dimming over the past 100 years. "A hundred years ago, VY CMa used to be visible to the naked eye," said Montargès.

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, one of the brightest stars in the sky, may have a secret sunlike companion that drives the star’s mysterious six-year-long "heartbeat," new research suggests.
