The Kepler 90 System

The busy week of launches wasn’t the only thing going on of course, NASA announced the discovery of an eighth planet around a star called Kepler-90. The discovery was made using AI and the system is as large as our own.

Big news indeed.

From NASA: Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler Space Telescope. This artist’s concept depicts the Kepler-90 system compared with our own solar system.

The newly-discovered Kepler-90i — a sizzling hot, rocky planet that orbits its star once every 14.4 days — was found using machine learning from Google. Machine learning is an approach to artificial intelligence in which computers “learn.” In this case, computers learned to identify planets by finding in Kepler data instances where the telescope recorded changes in starlight caused by planets beyond our solar system, known as exoplanets.
