The troposphere ends abruptly at the tropopause, which appears in the image as the sharp boundary between the orange- and blue- colored atmosphere. The silvery-blue noctilucent clouds extend far above the Earth's troposphere. The sliver of the setting moon is visible at upper right.EPA PHOTO/EPA/NASA HO For editorial use only! \ape\Upload\photos.txt\INT11035107 }
