🪐 When AI found a planet humans missed نموذج
A neural network spotted an eighth planet around the star Kepler-90.
اللغز
NASA's Kepler telescope collected years of starlight data. Astronomers had already checked it — so how was a planet still hiding in it?
الإجابة
In 2017, researchers trained a neural network to recognise the tiny dip in brightness when a planet passes in front of its star. Searching weak signals people had skipped, it found Kepler-90i, making Kepler-90 the first known star besides the Sun with eight planets.
