Same class of algorithms used by Google and Netflix can also tell us if distant planetary systems are stable or not. Machine learning is a powerful tool used for a variety of tasks in modern life, from fraud detection and sorting spam in Google, to making movie recommendations on Netflix. Now a team of researchers from the University of Toronto Scarborough has developed a novel approach in using it to determine whether planetary systems are stable or not.

“Machine learning offers a powerful way to tackle a problem in astrophysics, and that’s predicting whether planetary systems are stable,” says Dan Tamayo, U of T Scarborough...
