Who Turned off the Lights on Betelgeuse? (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 summarises the discovery.

The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces. The video is available in 4K UHD.
