Written last Christmas to celebrate the 45th anniversary of the image, Jeffrey Kluger’s TIME article tells the story of one of humanity’s most celebrated images: the Earthrise shot from Apollo 8. As Kluger says,

It’s the picture that was credited with starting the environmental movement, that has been on postage stamps and t-shirts, album covers and coffee mugs, that has been used as a hopeful symbol of global unity at peace rallies and health conferences, on Christmas cards and in works of art.

His story is a great read.
