    Date de publication:

    25 Juin 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.
