NoctilucentClouds.jpgNoctilucent Clouds over Sweden75 visiteCaption NASA:"Sometimes it's night on the ground but day in the air. As the Earth rotates to eclipse the Sun, sunset rises up from the ground.
Therefore, at sunset on the ground, sunlight still shines on clouds above. Under usual circumstances, a pretty sunset might be visible, but unusual noctilucent clouds float so high up they can be seen well after dark.
Pictured above last month (September 2007), a network of noctilucent clouds cast a colorful but eerie glow after dusk near Vallentuna, Sweden.
Although noctilucent clouds are thought to be composed of small ice-coated particles, much remains unknown about them. Satellites launched to help study these clouds includes Sweden's Odin and NASA's AIM.
Recent evidence indicates that at least some noctilucent clouds result from freezing water exhaust from Space Shuttles".MareKromium10/30/07 at 10:19MareKromium: Alla NASA questa (secondo me abbastanza ridicola) ...
