What is Earthshine? Earthshine is the soft, faint glow on the dark side of the moon, caused by sunlight reflecting off Earth's surface. This phenomenon, also known as the "ashen glow" or "Da Vinci glow," is most visible during a crescent moon phase. Why does Earthshine occur? When sunlight hits Earth, some of it bounces back into space, illuminating the moon's night side. This reflected light is what we see as Earthshine. Why is Earthshine important? It helps scientists study Earth's climate and albedo, which is the measure of how much sunlight our planet reflects. Can you see Earthshine with the naked eye? Yes, especially during the first few days after a new moon. Want to learn more? Here are 35 fascinating facts about Earthshine that will illuminate your understanding of this celestial phenomenon.
