What Can Cave Life Tell Us About Alien Ecosystems?
Extremophiles, or microbes that live in the most seemingly hostile environments, are the darlings of astrobiologists, who study the potential for life beyond Earth. In this episode, co-host Janna Levin speaks with astrobiologist and cave explorer Penelope Boston about how life finds a way — and whether it might have found a way elsewhere in our solar system or around a distant star.

If instruments do someday detect evidence of life beyond Earth, whether it’s in this solar system or in the farther reaches of space, astrobiologists want to be ready. One of the best ways to learn how alien life might function can be to study the organisms called extremophiles, which live in incredibly challenging environments on or in the Earth.
In this episode, Penelope Boston, a microbiologist who has worked for many years with NASA, speaks with Janna Levin about the bizarre life found in habitats such as caves, how it would be possible to detect life beyond our solar system and what it would mean for humanity if we do.
