With every new planet found orbiting a distant star, a world of possibilities opens. Our knowledge of the universe stretches. New questions arise. Exoplanets capture our imaginations. The Transiting Exoplanet Survey Satellite (TESS) will scour the skies in a 2-year mission to discover more exoplanets, planets found orbiting stars outside our solar system, than ever before. Come along on the journey with ABCs of Exoplanets. To bring these worlds to yours, download the ABCs of Exoplanets mini-posters.
