Saturn-like planet orbiting a small, cool starby detecting the "wobble" in the star’s motion caused by the gravitational pull of the planet. This is the first time that this technique is successfully employed with observations obtained at radio wavelengths. For their observations, the researchers used a network of radio antennas that are linked together to form a continent-size radio telescope. The discovery was possible thanks to the extremely high precision measurements of the star’s position that can only be achieved with such a radio telescope network.
