This animation illustrates how dust particles with ice crystals form mesospheric clouds. 10154 AIM's Cosmic Dust Experiment and Cloud Formation
Because of their high altitude, near the edge of space, noctilucent clouds shine at night when the Sun's rays hit them from below while the lower atmosphere is bathed in darkness. Also known as Polar Mesospheric Clouds or PMCs, they typically form in the cold, summer polar mesosphere and are made of water ice crystals. In April 2007 the Aeronomy of Ice in the Mesosphere (AIM) Mission was launched with the express purpose of studying noctilucent clouds. 10002 Noctilucent Cloud Animation
