We know there’s life in the Universe. We see it all around us here on Earth. But is there life anywhere else? By studying the extremes that life can take here on Earth, scientists are learning just how hardy and adaptable life can really be. And if you consider other ways that life might function, the options open up considerably. This week we’ll discuss the study of life – extreme life here on Earth, and the possibility of finding life on other worlds.

Ep. 142: Plate Tectonics
The surface of the Earth feels solid under your feet, but you’re actually standing on a plate of the Earth’s crust. And that plate is slowly shifting across the surface of the Earth. Over geologic timescales, plate tectonics has totally resurfaced our planet, bringing continents together, and tearing them apart. We know we have plate tectonics here on Earth, but what about other worlds?
Questions Show: Avoiding the Heat Death, Orbiting Galaxies, and the Dangers of Space Radiation
Will robots be able to avoid the heat death of the Universe? Can galaxies orbit each other like binary stars? And what are the dangers of space radiation to astronauts on the Moon?
