    June 26, 2012

    Using the Hubble Space Telescope (NASA/ESA), the astronomers observed important changes in the upper atmosphere of a remote planet. Just after a strong eruption on its host star was observed in the X-rays range, the planet experienced a violent atmospheric escape. It was the first time such detailed observation of variations in the atmosphere of an extrasolar planet was performed; this result contributed to our knowledge of climatic variations and meteorological alterations in extreme conditions.

    June 29, 2012

    En utilisant le Télescope spatial Hubble (NASA/ESA), les astronomes ont observé des changements importants dans la haute atmosphère d'une planète lointaine. Juste après une forte éruption de son étoile observée en rayons-X, la planète a subi un violent épisode d'échappement atmosphérique. Il s'agit de la première observation détaillée de variations dans l'atmosphère d'une planète extrasolaire; ce résultat contribue à notre connaissance des variations climatiques et des changements météorologiques dans des conditions extrêmes.

    Publishing date:

    April 4, 2011

    La surface de tous les corps célestes en témoigne : les collisions sont monnaie courante dans l'espace. Pour nous, la question n'est pas de savoir si, un jour, un astéroïde de grande taille nous percutera, mais plutôt “quand ?”.
