(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) -- A month and a half ago -- 46 days -- Malaysia Airlines Flight 370 vanished over the southern Indian Ocean. The milestone is a somber one because it now allows attorneys to move in. There's a 45-day federal law that says American lawyers have to wait that long to reach out to a family that's lost a loved one in a plane crash. What it means is that families can now file suit in American courts against U.S. aircraft manufacturer Boeing Co. The only problem: No wreckage has been found. It's kind of like a murder case without a body.Underwater drone is continuing its 10th mission Wednesday morningMeeting with Chinese families is postponed again"We want our loved ones back," father of missing passenger saysMalaysia Airlines Flight 370 went missing 46 days ago
