In my childhood, while seeing a waxing crescent (new moon) I sometimes had a sense of supernatural powers that I can see the darker part of the moon as well!
With the passage of time, I came to know it wasn’t out of this world kinda thing, it’s called Earth Shine or Da Vinci Glow. It’s a natural phenomenon, that Moon’s darker part seems lightened up a bit in early days of a lunar month.
Reason for the phenomenon is this path of light:
Sun light => Earth => Reflection from earth surface => incident on moon => Moon Glows!
Promise me you won’t call me eccentric if I say something seemingly weird..
Just like Moon seems glowing because of Sun’s reflected light from it’s surface, similarly Earth also seems lightened up because of the Sun’s reflected light.
You better tell me it’s reason why 😛
Also, by observing this planetary reflection phenomenon, I ask you one thing:
Why can’t you see Earthshine over moon when Moon is comparatively more lit up? e.g. half lit moon like on 7th or 8th night of a lunar month.
Hint: It has something to do with position of moon.
At the end, I’d like to share my first ever captured earthshine. Captured on Ramzan 3rd on May 18, 2018.
