Sara Seager’s research led to the first discovery of an atmosphere on a planet outside our solar system. Now she’s on the hunt for a twin Earth.

Why you should listen

Having helped pave the way for the current torrent of discoveries of planets outside of our solar system (or exoplanets), 2013 MacArthur Fellow Sara Seager is now preparing to fulfill her life dream of discovering a planet with nearly identical conditions to our own.

Seager’s present research and discovery mission projects include Earth-orbiting nanosatellite telescopes as well as the Starshade, a sunflower-shaped giant screen to block intrusive starlight, allowing a space telescope to zoom in on the small exoplanets that have thus far eluded our sight.
