EVSN - Betelgeuse Smaller Than Previously Calculated, Still A Mystery
From February 10, 2021.
Hosted by Dr. Pamela L. Gay.
Scientists collected fresh data on Orion's bright star Betelgeuse to try and understand this star that caused so much controversy. They found it's smaller than previously calculated, and last year's dimming was likely caused by dust, but it's also more complex than thought. Plus, galaxies, Earth's forests, ice on Mars, and Saturn's moon Rhea.
