The Kepler space telescope has produced more than 30,000 signals of possible planets circling distant stars. Researchers taught a computer to “learn” how to identify the weak signals of a planet crossing its star using a neural network. A search for new worlds around 670 known multiple-planet systems using this machine-learning technique yielded not one, but two discoveries: Kepler-90i and Kepler-80g. Credit: Google
