Who Turned Off the Lights on Betelgeuse? | ESO

ESOcast 238 Light: When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new research done with ESO's Very Large Telescope and Very Large Telescope interferometer that solves the mystery of Betelgeuse's dimming. This ESOcast Light summarizes the discovery.
