Polar Mesospheric Clouds

Apr 30, 2014 Could noctilucent clouds be part of Earth’s auroral phenomena? On April 25, 2007 NASA launched the Aeronomy of Ice in the Mesosphere (AIM) spacecraft on a multi-year mission to study the highest visible clouds, otherwise known as polar mesospheric clouds, or noctilucent clouds.

Oxygen on Rhea

  Apr 29, 2014 Where did the extremely rarified atmosphere on Rhea come from? Relative to Saturn, Rhea is most likely negatively charged. Saturn’s powerful opposite charge is probably initiating an electric discharge, causing the water in Rhea’s icy surface to dissociate, so the presence of oxygen around the moon is not…
