GRAVITATIONAL TUG OF ‘INVISIBLE’ EXOPLANET DISCOVERED
NASA’s Kepler space telescope finds planets beyond the solar system by looking for dips in starlight caused by planets parading past their parent stars, relative to Kepler’s point of view.
But there’s another method by which scientists can find sibling Kepler worlds beyond the telescope’s eye.
