Molecules vital to life have been detected in outer space and isolated in meteorites and comets. Some of this material that rained down on Earth may have jump-started biology. If so, these space seeds also may have planted a particular molecular orientation, or "handedness," that spread to the world's first creatures. New research is studying how this handedness could arise in space.
