Astronomy Cast Ep. 705: Water Worlds - Looking For Life Beyond Earth

by Fraser Cain & Dr. Pamela Gay

Streamed live January 17, 2024.

Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe, and hopefully we can find evidence of life. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?
