Episode 764: Habitable Hycean Worlds: An interview with Dr. Nikku Madhusudhan
October 18th, 2021 | 54 mins 40 secs
astronomy, space, space exploration
My guest today is Dr. Nikku Madhusudhan, a PhD astronomer at the University of Cambridge. 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.
