(CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come. Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet. With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.For the first time, eight planets have been found orbiting Kepler-90It is tied with our solar system for a star hosting the most known planets

(CNN) -- With all passengers and crew aboard Asiana Airlines Flight 214 from Seoul now accounted for, air crash investigators are beginning the painstaking search for clues as to why the incident, which killed at least two people, happened. While the sequence of events that led to accident remains unclear, witnesses described hearing a "boom" as the Boeing 777 appeared to come in short, touching down heavily on the runway close to the water's edge at San Francisco International Airport before it disappeared in a cloud of smoke. Parts of the aircraft, including its tail section and engines, snapped off as it spun off the tarmac on its belly.Witnesses describe hearing a "boom" as the flight from Seoul landed shortTilmon: "Pilot did not have enough power available to correct the rate of descent"A British Airways Boeing 777 landed short at London Heathrow in 2008 due to ice in fuelCurtis: Information from crew about moments before landing will be critical
