This powdery dust is the result of billions of years of meteor impacts that also created the moon’s cratered surface we see today. Scientists believe electric charges build up at the boundary where the “daytime” (or light) and “nighttime” (or dark) sides of the moon meet. These charges could possibly lift dust from the surface high into the moon’s atmosphere.
