Earthshine is now well understood as sunlight from Earth’s clouds being reflected back onto the lunar surface producing this beautiful soft glow on the Moons unlit surface.
I post a lot of my images onto Dr Tony Phillips website called Spaceweather.com
Dr Phillips has written an article call ‘What is the Da Vinci Glow?’ It’s a very interesting read, please go to the link below and see how Leonardo Da Vinci over 500 years ago worked out what earthshine really was :-)
I found this really nice YouTube video by Dr John Mason from the Southern Downs Planetarium & Science Centre. Where he takes you outside into the garden to look at the Earthshine on the Moon and view the De Vinci Glow. His view on this night was very similar to what I have captured here with my image.
