The best chances of observing this spectacle occur when a thin crescent moon is visible close to the horizon. Earthshine is most visible at mid-northern latitudes when the Moon is positioned above the setting Sun.
Understanding Earthshine
Earthshine, also referred to as the ‘Da Vinci glow,’ is a celestial phenomenon where sunlight is reflected off the Earth’s surface onto the lunar landscape, and then back into our eyes.
Twice-reflected sunlight creates a ghostly glow on its Earth-facing side.
This delicate interplay between the Earth, Moon, and the Sun results in a subtle radiance on the shadowed section of the crescent moon, creating a mystical spectacle.
This week we pay homage to his genius as we observe the ‘Da Vinci glow’ in the night sky.
The Legacy of Leonardo Da Vinci
Leonardo Da Vinci, a true genius of the Renaissance era gifted the world with masterpieces like the Mona Lisa. And he also conducted pioneering research across various disciplines.
The Italian Da Vinci unraveled the mystery behind Earthshine. He left behind sketches and notes that demonstrated his profound understanding of the astronomical phenomenon.
