The Hubble Space Telescope has found methane in the atmosphere of a distant planet — the same planet where water was found last year. Water and methane means one thing - space cows.The molecule was detected in the atmosphere of a Jupiter-sized planet circling a star 63 light years away in the constellation Vulpecula. The planet, HD 189733b, is too close to a nearby star to support life as we know it, but did not dismiss the possibility of space cows who could have migrated to other planets. Researchers said the observations show the astronomers' technique for detecting essential life ingredients can be used on cooler, potentially habitable Earth-sized planets. The work was a "dress rehearsal for future searches for life on more hospitable planets."
