Unwrapping the Mysteries of Betelgeuse with Dr. Meridith Joyce - Astronomy News with the Cosmic Companion Oct 27, 2020
The red giant star Betelgeuse is smaller and closer than astronomers believed - we talk to the astrophysicist who made the discovery.
Hello everyone:
This week, we are joined by Dr. Meridith Joyce of Australian National University. We will talk about her work finding that the star Betelgeuse is both closer, and smaller, than astronomers believed.
We'll also take a look at the OSIRIS-REx spacecraft, which touched down last week on the surface of the asteroid Bennu. We will also examine a new study identifying 1,000 worlds where extraterrestrial astronomers could – theoretically – easily see signs of life on Earth. Also, one exoplanet the size of Neptune is found orbiting far too close to its parent star. And, we take a look at findings from the ALMA network of radio telescopes, revealing the role volcanoes play in forming the atmosphere of Io, one of the largest moons of Jupiter.
