Artist’s view of the exoplanet HD189733b. Astronomers from the Universities of Geneva (UNIGE) and Berne have closely studied the atmosphere of the exoplanet HD189733b, thanks to new measurement techniques. Their findings were unveiled Monday. On this planet, it is 3000 degrees and altitude winds to several thousand km/h. http://orbiterchspacenews.blogspot.com/2015/04/unable-to-live-on-this-planet.html

Astronomers have for the first time managed to determine the colour of a planet outside the solar system, a blue gas giant some 63 light years away.

By being able to determine the amount of radiation reflected by exoplanet HD 189733b, NASA Hubble Space Telescope determines its color http://www.ibtimes.com/meet-new-blue-planet-nasa-hubble-telescope-reveals-exoplanet-hd-189733bs-true-color-photo-1342147
