The atmosphere of an extrasolar planet, 63 light years away in the constellation Vulpecula, containing methane and water vapor, according to research published today in the journal Nature. These findings from scientists at the California Institute of Technology and the University of Arizona (U.S.) help build a better understanding of atmospheric chemical processes and the extrasolar planet, called HD 189733b.
Previous research suggested that in the atmosphere could be water, but this study confirms this and also detects the presence of methane, but not found carbon monoxide a substance that is thought abundant in the upper layer of the atmosphere.
Thanks to the Hubble Space Telescope, which used a technique of infrared waves to determine the transmission spectrum have been captured chemical changes in atmospheric conditions that have allowed scientists to gather key information to confirm the presence of methane and water vapor.
Planet of hot Jupiters, "gas is made, as the giant of our solar system, but its orbit is much closer to the star. It has a mass of 0.15 higher than that of Jupiter and the astronomers calculate that the surface temperature is several hundred degrees.
