Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth. Could there be organisms living in their depths? Kevin Peter Hand’s new book “Alien Oceans: The Search for Life in the Depths of Space” reveals the science behind the quest to find out. Join us for a look at what we know about life on other planets in this installment of Leonard Lopate on WBAI.
