NASA ENLISTS GOOGLE AI TO FIND OTHER SOLAR SYSTEMS
KEPLER 90 HAS EIGHT ROCKS AROUND ITS SUN TOO.
Google and NASA announced the discovery of an 8th planet in the Kepler-90 system in December. The first example of a solar system with eight planets (other than our own) was actually uncovered by one of Google’s machine learning algorithms using the existing Kepler dataset. When planets orbit a star, their mass affects the light that is projected from it, making it wobble relative to us, creating a measurable decrease in lumosity. While the smaller planet’s effect was so subtle that it eluded mathematical detection by a human eye, Google’s AI software sniffed out the anomaly and found itself a new job in the process.
