For the first time, the rotation of a disc in which planets are born could be observed directly by mapping the emission of its dust grains. It is the disc that surrounds the young star AB Aurigae. Although it seems to rotate globally in accordance with the laws of physics, some regions close to the star show an unexpected deviation. The origin of this anomaly ? A beam of clues would indicate the presence of giant planets being formed. This study…
