Extremophiles, the Deep Sea, and Alien Life with Peter Girguis

What do deep-sea microbes and Martian “leopard spots” have in common? Marine biologist Peter Girguis thinks they might both hold clues to finding life beyond Earth. In this episode, he joins Hakeem for a journey from the ocean floor to outer space, sharing stories from his dives aboard the Alvin submersible and exploring how Earth’s most extreme lifeforms could help us find the first ETs. Along the way, he explains how Earth is truly a microbial planet — teeming with enough microbes to stretch across the galaxy –  reshaping how we think about life, both here and out there. Learn more about NOVA and subscribe to our YouTube channel. —————————Guest Bio: Peter Girguis is a professor of Organismic and Evolutionary Biology at Harvard University.
