Radio Stars: What's Up with Betelgeuse? (Part 1)

Betelgeuse is a red supergiant star visible to sky watchers in the "shoulder" of the constellation of Orion, the Hunter. In late 2019 Betelgeuse began to undergo a surprising "dimming" event before recovering its typical brightness several months later. In this two-part podcast, hear how astronomers have been using observations at radio wavelengths, combined with data from other telescopes, to uncover the cause of this historic dimming event, and what it means for the future evolution of this star.
