NASA finds a second solar system

The planet was found using a machine-learning system from Google, which was put to work sifting through data from NASA's Kepler spacecraft. Kepler, a space telescope that trails Earth in orbit around the sun, has stared down 145,000 sun-like stars over the years to look for signs of distant planets. Astronomers knew about the Kepler-90 solar system, but had not previously detected this planet. It appears to be the third planet from the sun-like star, and orbits roughly every 14 days. The temperature on Kepler-90i surface is likely around 1,800 degrees Fahrenheit (980 degrees Celsius). A team of NASA scientists who have scoured the universe looking for planets that could potentially hold alien life today made the historic announcement in a briefing at 6pm British time. It was to unveil the latest findings of the Kepler space telescope mission. Kepler 90i orbits its home star every 14 days and is about 30 percent bigger than Earth. The planets in the Kepler 90 system orbit much closer to their host star than Earth is to the sun. Neural networks can be trained on huge amounts of data to determine the difference between objects with great accuracy, the team explained in the teleconference.
