Space Talk: Intraterrestrials: Discovering the Strangest Life on Earth

Life thrives in the deepest, darkest recesses of Earth’s crust—from methane seeps in the ocean floor to the highest reaches of Arctic permafrost—and it is unlike anything seen on the surface. Join Karen Lloyd, professor at University of Southern California and author of Intraterrestrials: Discovering the Strangest Life on Earth, as we explore what scientists are learning about these strange types of microbial life—and how research expeditions to some of the most extreme locales on the planet are broadening our understanding of what life is and how its earliest forms may have evolved.
