This video explains about NASA’s newest planet discovery of Kepler-90i using Artificial Intelligence. This new exoplanet Kepler-90i was discovered by NASA in December 2017 as the 8th planet of Kepler-90 planetary system. An exoplanet is a planet which orbits a star, but it does not belong to our solar system. With this discovery, Kepler-90 planetary system is equal with our solar system as both of them having the equal number of planets around a single star. Accoring to NASA, our solar system and Kepler-90 planetary system have the highest number of plannets around a single star. The distance to Kepler90 star is 2,545 light-years from Earth. Kepler-90i is a too hot, rocky planet which orbits its star Kepler-90, once every 14.4 days. The average surface temperature of 800 °F suggests it is impossible to find a life form there. All Kepler-90 planets orbit close to their star than earth orbits sun. This planet discovery was made by applying Google machine learning and signal data from NASA’s Kepler Space Telescope. Machine learning is a form of Artifical Intelligence, where machines learn and adapt through experience. The transit method was used to discover this new Kepler planet. This technique detects distant planets by monitoring the brightness of many stars to look for perioic dimming of a star. Orbiting planet passes between its star and the Earth is the reason for this dimming phenomenon. The researchers Christopher Shallue and Andrew Vanderburg trained an Artificial Neural Network. Artificial Neural Network is a machine learning technique which act like a human brain. This network is used to identify transiting exoplanets by feeding the light readings of Kepler telescope. First, they fed neural network with train data set of 15,000 previously-verified Kepler signals. For the test set, the neural network has successfully identified true planets. Then, this well-trained neural network is directed to feed weaker signals in 670 star systems with known multiple planets. Suprisingly, they discovered Kepler-90i as a result In addition to Kepler-90i, this neural network has dicovered a sixth planet in the Kepler-80 system.
