Alan's done a beautiful thing with 300 Miles High. It's a collection of photos of Earth, taken from space. But the wodnerful part is that the photos are chosen with an emphasis on aesthetics, instead of science.
Contrasts nicely with Astronomy Picture of the Day, and when you see the pictures he's chosen, they can be astoundingly moving, if you're in the right mood. Reminds us what a new perspective can do.
from the depth of the pacific
to the height of everest
and still the world is smoother
than a shiny ball-bearing
so take a few steps back
and put on a wider lens
and it changes your skin,
your sex, and what you're wearing
