A team of American astronomers has pioneered a new method of observing exoplanets with the Gran Telescopio CANARIAS (GTC) that promises to give a leading role to large Earth-based telescopes. The results obtained from the study of two giant planets passing in front of their parent stars are of such high precision that the researchers are already planning to use this new technique to learn more about super-Earth sized planets and Neptune-sized planets that have been discovered by observatories in space. The new technique minimizes the distortion of starlight by the atmosphere through the use
