NASA scientists have found seven Earth-sized planets in a nearby solar system that could potentially support life, the U.S. space agency said Wednesday. The planets, all with the potential to hold life-sustaining liquid water, are orbiting a single dwarf star about 40 light-years away. Scientists initially reported the system last year, but at that point they thought only three planets were orbiting the star. The latest discovery, uncovered by NASA’s Spitzer Space Telescope, sets a record for the star with the greatest number of potentially life-supporting planets around it.
