In this episode, I speak about space with Sara Seager. Professor Seager is an astrophysicist and a professor of physics and planetary science at MIT. Her research, which earned her a MacArthur Foundation “genius” grant, has introduced many foundational ideas to the field of exoplanets. She has led different space missions or space mission concept studies, including NASA’s Probe-class study team for the Starshade project. She is now at the forefront of the search for the first Earth-like exoplanets and signs of life on them. Her memoir, The Smallest Lights in the Universe, was published in 2020.
