This photo is pretty amazing. It is the first photo, ever taken of Earth, from the Moon. The photo is turned sideways so I could fit it in the post, so click on it to see it full size. This photo was taken in 1966 by Lunar Orbiter 1. The photo was taken a couple years before the first humans landed on the Moon and took even more detailed, and colored photos. This may not be colored, and it may not look as spectacular as those photos, but this is may be one of  the most important photos in the history of mankind. Thanks to APOD.
