Hampton, VA (AHN) - Initial results of a National Aeronautics and Space Administration (NASA) satellite study of the polar night clouds indicate that the phenomenon is getting brighter and expanding, so that its visibility now reach farther from the poles.
Jim Russell, Hampton University's atmospheric science professor and lead researcher of the Aeronomy of Ice in the Mesosphere (AIM) satellite project, theorizes that global warming is causing the changes in night clouds. AIM is the first satellite to study the night clouds.
