My guest today is Dr. Alex Teachey, a Distinguished Postdoctoral Fellow at the Academia Sinica Institute of Astronomy & Astrophysics (ASIAA) in Taipei, Taiwan. Alex specializes in searching for moons orbiting extrasolar planets: exomoons. Learn why these could be some of the most interesting places to search for life in the Universe.https://alexteachey.wordpress.com/🚀 OUR WEBSITE:════════════════════════════════════https://www.universetoday.com/🚀 PODCAST LINKS:════════════════════════════════════RSS: https://universetoday.com/audioiTunes: https://universetoday.com/itunesSpotify: https://universetoday.com/spotify🚀 EMAIL NEWSLETTER:════════════════════════════════════Read by 50,000 people every Friday.

Dr. Madhusudhan is one of the researchers who investigated the habitability of "hycean worlds"; ocean worlds with a thick hydrogen ocean. These worlds are completely alien to anything we have in the Solar System, and yet, could have a much wider region that remains habitable than terrestrial planets.https://people.ast.cam.ac.uk/~nmadhu/Nikku_Madhusudhan/Home.html🚀 OUR WEBSITE:════════════════════════════════════https://www.universetoday.com/🚀 PODCAST LINKS:════════════════════════════════════RSS: https://universetoday.com/audioiTunes: https://universetoday.com/itunesSpotify: https://universetoday.com/spotify🚀 EMAIL NEWSLETTER:════════════════════════════════════Read by 50,000 people every Friday.
