NASA's prolific Kepler space telescope, which shut its powerful eye nearly five years ago, continued finding exoplanets even while taking its final breaths.

A team of astrophysicists and citizen astronomers combing through the last chunk of data that Kepler sent home say they found two new worlds and a "candidate" planet closely orbiting three faint stars about 400 light-years from Earth.
