An artist's illustration of the Kepler 11 solar system featuring a Sun-like star and six planets. Telescopes designed to search for planets are finding more and more worlds with a chance of discovering life, including over 50% of the potential planets in the habitable zone. NASA's chief scientist said that "strong evidence" of extraterrestrial life will be discovered within a few years
