Betelgeuse’s mysterious ‘Great Dimming’ may be caused by a wandering black hole

In late 2019, the star Betelgeuse has dimmed by 60%. While it’s impossible to pinpoint exactly what caused this, new research suggests that a wandering companion may have played a role. By swinging close to the giant star, the interferometer may have caused the tides to swell, causing the surface of Betelgeuse to darken. While this scenario cannot explain the full amount of the observed dimming, it may have caused other effects on the star that made the problem worse, researchers suggest in a new research paper.

Betelgeuse is one of the most easily recognizable stars in the sky. You can see it as Orion’s bright red shoulder and is usually the tenth brightest star in the sky. If you will put the red giant in our area Solar SystemYou’ll swallow all the inside rocky planets It extends from the sun to the asteroid belt between them Mars And the Jupiter.
