For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves to the other side of its host star. The planet has the smallest orbit so far of all directly imaged exoplanets, lying as close to its host star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. This discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms. ________________________________________________________________ Un exoplaneta captado en movimiento. Por primera vez, los astrónomos han sido capaces de seguir directamente el movimiento de un exoplaneta desplazándose desde un lugar a otro de su estrella anfitriona. El planeta posee la órbita más pequeña que se conoce de todos los exoplanetas fotografiados directamente, con una distancia a su estrella similar a la que existe entre Saturno y el Sol. El descubrimiento prueba que los planetas gaseosos pueden formarse al interior de discos en sólo unos pocos millones de años, un breve tiempo en térmicos cósmicos. ________________________________________________________________ Visual design and editing: Martin Kornmesser and Luis Calçada.
