Description

http://www.facebook.com/liberascienza In questo episodio di Hubblecast, Dr J (aka Dr Joe Liske) presenta l'ultima scoperta di Hubble sul pianeta extrasolare HD 189733b. Nel 2011 è stata osservata da Hubble l'espulsione dell'atmosfera esterna del pianeta mentre il satellite Swift riprendeva un brillamento della stella attorno a cui orbita HD 189733b. È la prima volta che si osserva chiaramente una trasformazione nell'atmosfera in un pianeta al di fuori del sistema solare. In this episode of the Hubblecast, Dr J (aka Dr Joe Liske) presents the latest discovery about HD 189733b, an exoplanet that has been repeatedly studied by Hubble. Observations taken in 2011 using Hubble and the Swift satellite showed a flare from the planet's parent star scorching the upper atmosphere and driving it off into space. This is the first time that clear change has been observed in an exoplanet's atmosphere. The observations give a tantalising glimpse of changing weather on planets outside our Solar System.
