Description
January 30, 2010 - Polar mesospheric clouds over the Southern Hemisphere. These clouds occur over the high latitudes of both the Northern and Southern Hemispheres during their respective summer months at very high altitudes (approximately 76 to 85 kilometers, or 47 to 53 miles). They are most visible during twilight, when the clouds are still illuminated by the setting Sun, while the ground is already dark.Polar mesospheric clouds are also known as noctilucent or night-shining clouds. The clouds exhibit thin, wispy light blue forms that contrast with the darkness of space (image upper right). Lower levels of the clouds are more strongly illuminated by the Sun and appear light orange to white. Clouds closest to the Earth’s surface are reddish-orange (image center).
