July 10, 2012
This artist's rendering illustrates the evaporation of HD 189733b's atmosphere in response to a powerful eruption from its host star. NASA's Hubble Space Telescope detected the escaping gases and NASA's Swift satellite caught the stellar flare. The international team of astronomers in this study consists of A. Lecavelier des Etangs (Institut d'astrophysique de Paris, CNRS, UPMC, France), V. Bourrier (Institut d'astrophysique de Paris, CNRS, UPMC, France), P. J. Wheatley (Department of Physics, University of Warwick, UK), H. Dupuy (Institut d'astrophysique de Paris, CNRS, UPMC, France), D. Ehrenreich (Institut de Planetologie et d'Astrophysique de Grenoble, UJF/CNRS, Grenoble, France), A. Vidal-Madjar (Institut d'astrophysique de Paris, CNRS, UPMC, France), G. Hebrard (Institut d'astrophysique de Paris, CNRS, UPMC, France), G. E. Ballester (Lunar and Planetary Laboratory, University of Arizona, USA), J.-M.
