So, it wasn’t the discovery of alien life out there that NASA announced this week. It was instead the finding of an eighth planet circling the star, Kepler 90, about 2,500 light years away. The scientist compared the Kepler 90 system to our own, noting that the planets are bunched closer together.
Lost in all the excitement of finding a mini copy of our solar system was the way the new planet was discovered. NASA scientists taught their image analyzing computers to find new objects in space by utilizing “machine learning.”
