NASA’s free interactive photo book shows the abstract beauty of Earth.

NASA has studied our planet in novel ways, using ingenious tools to study physical processes at work—from beneath the crust to the edge of the atmosphere.

For all of the dynamism and detail NASA can observe from orbit, sometimes it is worth stepping back and simply admiring Earth.

It is a beautiful, awe-inspiring place, and it is the only world most of us will ever know.

Earth book available on EPUB, PDF and HTML.
