Moon Engulfed in Permanent, Lopsided, Dust Cloud

New science results from NASA’s Lunar Atmosphere and Dust Environment Explorer, or LADEE, mission indicate that the moon is engulfed in a permanent, but lopsided, dust cloud that increases in density when annual events like the Geminids meteor shower spew shooting stars, according to a new study led by University of Colorado Boulder.

This image shows an artist's conception of the lunar dust exosphere surrounding the moon. The color represents the amount of material ejected from the surface, showing a peak in the apex direction. A haze of dust is shown around the moon. Gray faded circles are overlaid on the lunar surface to represent the random nature of the primary impactors. An artist's conception of the LADEE spacecraft's trajectory is also shown.
