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.
star called TVLM 513–46546
