A new potentially life-bearing "super-Earth" has been discovered orbiting a relatively nearby star. Described as the "best candidate" for supporting liquid water -- and therefore life -- the planet (GJ 667Cc) is believed to be about 4.5 times the size of Earth. The parent star (GJ 667C) is 22 light years away, and this is the second potentially Earth-like rock scientists have discovered orbiting the M-class dwarf. With a 28.15 day cycle, it's calculated to receive 90 percent as much light as Earth, and much of that is infrared (meaning the ac
