IHY OBSERVATORY OF THE WEEK


AIM

The Aeronomy of Ice in the Mesosphere (AIM) Mission was launched April 25 to study Polar Mesospheric Clouds (PMCs), also called noctilucent clouds, to find out why they form and why they are changing. Noctiucent means "night shining," as these clouds are 50 miles high in a layer of the atmosphere called the mesosphere. Also unlike normal clouds, these clouds can only be seen near twilight, when the sun is just below the horizon and the sky is dark.
