Instructed to work out the brightness of particular stars captured by NASA’s TESS (Transiting Exoplanet Survey Satellite), Wolf Cukier, NASA’s intern, by mere chance, discovered a new planet seven times the size of Earth.

A 17-year-old intern was searching in a database “for everything the volunteers had flagged as an eclipsing binary, a system where two stars circle each other, and from our view eclipse each other every orbit.” A stellar eclipse at first thought, by examining transits (small dips in starlight), it later turned out to be TOI 1338 b—the first planet discovered by TESS, situated some 13,000 light-years away from Earth, in the constellation known as Pictor. Being a circumbinary planet, it revolves around two stars, and its size is approximately seven times bigger than the size of ours, or almost the size of Saturn.
