In December 2019, astronomers noticed the brightest star in the constellation of Orion, the red supergiant Betelgeuse, started to dim more than it has in the past century to about one-third of its normal brightness. This unprecedented dimming was distinguishable with the unaided eye, but by March 2020, Betelgeuse had begun to recover and get brighter again.
What happened? Why did Betelgeuse dim? Join Peter Plavchan and Michael Summers, professors of astronomy and physics at George Mason University, and Dr. Natalie Hinkel, planetary astrophysicist at the Southwest Research Institute, to learn about stellar evolution and the life and death of red giants, yellow suns, and brown dwarfs.
With remote control of the GMU Observatory, Plavchan and Summers bring the skies into your living room. Weather permitting, enjoy a remote telescope viewing session of celestial objects after the program.
