Scientists finally find explanation for lopsided cloud that follows Earth's moon through space

Scientists have solved the mystery behind the moon's lopsided dust cloud, which contains more particles on the sun-facing side than the dark side. Computer simulations revealed that extreme temperature differences between the moon's scorching daytime (233°F) and frigid nighttime (-297°F) surfaces cause this asymmetry. Meteoroids hitting the hotter daytime surface kick up 6-8% more dust particles with enough energy to reach detectable heights above the lunar surface.
