"Twin" Solar System Discovered

Sat Dec 16, 2017 10:03 AM

Google AI used machine learning to help researchers discover a solar system that rivals our own in number of planets. Kepler 90, a G-class star located over 2500 light years away in the constellation Draco, now has 8 planets in its system. Google's AI system learned to sift through data from the Kepler Space Telescope by first examining strong signals from known exoplanets and then reexamining weak signals. This new method of hunting for exoplanets has the potential to find even more rocky worlds orbiting their stars - potential Earth-like planets.

While the Kepler-90 system has the same number of planets as ours, with the same arrangement of smaller rocky planets closest to Kepler-90 and larger planets farthest away, there are differences. All of the planets in this system discovered thus far are closer to their star than the Earth is to the sun. While this probably rules out the likelihood of life existing on one of these worlds, it does leave open the possibility of the discovery of more planets in the unexplored space farther out in this system. There soon may be a known planetary system larger than our own.
