Discovery of exoplanets, small planets beyond our solar system, detected only by the gravitational "wobble" they cause in the stars they orbit. The Genesis space probe has been collecting solar particles that flow out from the Sun and is returning to Earth with its cosmic cargo, where it will be retrieved by two Hollywood stunt men. Voyager 1, launched in 1977, is heading out of the solar system carrying sounds of Earth life.
