Our tiny blue planet is an oasis in the blackness and vastness of outer space. It is our home and our protector from the violence and radiation that permeates the universe. Though we see it up close every day of our lives, its real beauty can only be appreciated from a distance in space. We have created a fleet of spacecraft to take us into Earth orbit, and from there we look back at our fragile, blue world. The images in this gallery have been hand-selected by Sea and Sky for their visual beauty and represent some of the best images ever obtained from Earth orbit.
