The photo above showing a fascinating display of noctilucent clouds was captured over Swindon, UK on July 14, 2006. These rapidly moving "nighttime" clouds are observed in twilight, typically at latitudes poleward of about 50 degrees. They form at altitudes of approximately 80 km (50 mi) above the Earth's surface, and they're believed to consist of ice covered particles, possibly meteoritic dust.

Photo details:1 second exposure at f/3.2, Canon Powershot, time of image was 10:41 p.m. (local time).
