New radio wave technique could detect alien planets, receive interstellar tunes

Any experienced planet hunter will tell you: finding exoplanets is the real challenge, where hardened professionals go to test their mettle. These tricky bodies stymie conventional methods - like seeing a planet pass in front of its parent star - because exoplanets often have decades-long orbits, meaning you could spend a lot of lonely nights fruitlessly searching the skies. So scientists at the University of Leicester in England developed a new approach: looking for radio waves emitted when
