BBC News : Astronomers may have found a way to identify those Sun-like stars most likely to harbour orbiting planets.A survey of stars known to possess planets shows the vast majority to be severely depleted in lithium.To date, scientists have detected just over 420 worlds circling other stars using a range of techniques.
