“Earthshine Moon over Sicily” is copyrighted by Dario Giannobile. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteWe can see the entire face of this crescent Moon due to earthshine. Earthshine occurs when sunlight reflects off Earth and illuminates the part of the Moon not directly lit by the Sun. When the Moon is a slim crescent from Earth, the Earth appears nearly full from the Moon, making the earthshine brightest. This phenomenon is also called the Da Vinci glow.
