What planets orbit the stars that shine brightly in our night sky? Are they gargantuan or minuscule? Warm or chilly? Part of a family or on their own? Meet the astronomers studying these exciting planets with NASA’s Transiting Exoplanet Survey Satellite, TESS. Learn with hands-on activities about the TESS mission (in operation since 2018!) and how astronomers at MIT and the Center for Astrophysics | Harvard & Smithsonian use this tiny but mighty telescope to find weird and wonderful worlds called “exoplanets”.
