Why Did Betelgeuse Dim? Dr. Andrea Dupree, Center for Astrophysics - Astronomy News with The Cosmic Companion Aug. 25, 2020 Video and Podcast

The recent dimming of Betelgeuse had skygazers scratching their heads. Listen to Dr. Andrea Dupree from the Center for Astrophysics talk about how her team solved the mystery of Betelgeuse.

Hello Everyone:

This week, we are joined by Dr. Andrea Dupree, senior astrophysicist with the Harvard-Smithsonian Center for Astrophysics. She recently carried out a study showing why the red supergiant star Betelgeuse recently dimmed, a sight seen by millions of amateur astronomers worldwide.

We also look at how the development of life on Earth may have been shaped by a nearby supernova explosion, and we take a look at a new study suggesting the Sun may have once had a stellar companion, with whom it was born billions of years ago. Meanwhile, NASA charges batteries on the first helicopter ever headed to another planet.

ALSO - We have a new format for these weekly updates about the show. The podcasts, which were hosted here on Substack, will now be hosted on Anchor.fm. Newsletters on Substack will remain unaffected.

If you listen to this show on TuneIn, Apple Podcast, Google Podcast, or another provider, you may see some difficulties in the next week or so that will, hopefully, be ironed out.

If you listen through these mailings every week, we will be providing shows in this new style:
