Professor of Aeronautics and Astronautics
Class of 1941 Professor of Planetary Science
Sara Seager’s current research interests are focused upon the discovery and characterization of exoplanets. She has two main goals: the discovery of another Earth and the search for signs of life by way of atmospheric biosignature gases. Thousands of exoplanets are known to exist with exoplanet atmospheres a firmly established field of research. Exoplanet atmosphere observations, are however mostly limited to giant exoplanets with puffy atmospheres. Seager’s group aims to understand the atmospheric composition and the interior structure of small rocky exoplanets, of the kind with potential to host life.

Professor Sara Seager is an astrophysicist and a Professor of Physics, Professor of Planetary Science, and a Professor of Aeronautics and Astronautics at the Massachusetts Institute of Technology where she holds the Class of 1941 Professor Chair. She has been a pioneer in the vast and unknown world of exoplanets, planets that orbit stars other than the sun. Her ground-breaking research ranges from the detection of exoplanet atmospheres to innovative theories about life on other worlds to development of novel space mission concepts.
In space missions for planetary discovery and exploration, she was the Deputy Science Director of the MIT-led NASA Explorer-class mission TESS; she was PI of the JPL-MIT CubeSat ASTERIA; is a lead of the Starshade Rendezvous Mission (a space-based direct imaging exoplanet discovery concept under technology development) to find a true Earth analog orbiting a Sun-like star; and most recently leads a team working to find out whether or not the Venus atmosphere can support life.
Her research earned her a MacArthur “genius” grant and in addition Professor Seager is an Officer of the Order of Canada, a member of US National Academy of Sciences, a recipient of the Magellanic Premium Medal, and has Asteroid 9729 named in her honor.
