NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the "habitable zone" where liquid water could exist on a planet's surface. These are the smallest exoplanets ever confirmed around a star like our sun. The discovery marks the next important milestone in the ultimate search for planets like Earth.

TRT – 00:24 – “I think we are after the biggest question in all of science, which is are we alone?  And the way we are going to answer that question is astronomers are going to go and find planets just like the ones being announced today but farther from there stars that truly may have liquid water and life and then we are going to figure out clever techniques such as the atmospheres of those planets and figure out if there actually is life on surface of those worlds.”
