This photo was taken from a craft orbiting the moon, while the earth was between the moon (or at least the orbiting craft) and the sun. http://spacefellowship.com/News/?p=8229. WOW. People on earth would be seeing some degree of lunar eclipse, this says a penumbral eclipse. It's one thing to picture this, but it's gorgeous to see it.
(After I originally posted this, my husband pointed out a simple oversight on my part -- From the moon, this would be a solar eclipse, as the earth is occulting the sun. Were the people orbiting the moon seeing the moon's shadow on the earth, with the sun behind, that would be a terrestrial eclipse.)
