“New details about Betelgeuse’s companion star”

Betelgeuse is a famous bright red star in the constellation Orion the Hunter. It’s famous in part because it will one day explode. Late last year, scientists announced Betelgeuse likely has a companion, which has since been confirmed and nicknamed Betelbuddy.
On Wednesday, researchers from Carnegie Mellon University said their observations show the companion star is not what they expected.
