Description
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.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support Get full access to The Cosmic Companion at thecosmiccompanion.substack.com/subscribe
