The Abyssal Habitable Zone: Ocean Worlds Near and Far

Explore the concept of the abyssal habitable zone in ocean worlds through this 29-minute lecture by Baptiste Journaux. Delve into the complexities of the canonical habitable zone and its limitations, examining the effects of pressure, various ice types, and planet mass on potential habitability. Learn about exoplanets and their characteristics, and understand how simple experiments and advanced techniques like ultrasonic sound speed measurements and diamond cell studies contribute to our understanding. Investigate the role of salt solubility, melting point depression, and hydrates in shaping ocean worlds. Gain insights into the possibilities of life in extreme environments near and far in our universe.
