Looking at Betelgeuse in a New Light - Dr. Meridith Joyce ANU - Astronomy News with The Cosmic Companion October 27, 2020

<p>Dr. Meridith Joyce of Australian National University joins us on the &nbsp;show, talking about her new finding showing that the red giant star Betelgeuse is both smaller and closer than we believed. &nbsp;&nbsp;</p> <p>We'll also take a look at the OSIRIS-REx spacecraft, which touched down &nbsp;last week on the surface of the asteroid Bennu. We examine a &nbsp;new study identifying 1,000 worlds where extraterrestrial astronomers &nbsp;could – theoretically – &nbsp;easily see signs of life on Earth. Also, one &nbsp;exoplanet the size of Neptune is found orbiting far too close to its &nbsp;parent star. And we take a look at findings from the ALMA network of &nbsp;radio telescopes, revealing the role volcanoes play in forming the &nbsp;atmosphere of Io, one of the largest moons of Jupiter.</p> --- Send in a voice message: https://anchor.fm/the-cosmic-companion/message Support this podcast: <a href="https://anchor.fm/the-cosmic-companion/support" rel="payment">https://anchor.fm/the-cosmic-companion/support</a>
