Earthshine, also known as lunar glow, is a faint illumination that brightens the dark side of the Moon. This occurs when sunlight is reflected off the Earth’s surface and then bounces back onto the Moon.
Earthshine is also referred to as ashen glow, the old Moon in the new Moon’s arms, or the Da Vinci glow, in honor of Leonardo da Vinci, who first described this phenomenon in recorded history.
