Beginning in 1968, when Apollo 8 set out for the moon, the human vision of the earth changed and will never be the same again. Satellite photography has shared many new visions of our world with the general public.
Apollo 8 astronaut Bill Anders said it all. "We came all this way to explore the moon, and the most important thing is that we discovered the Earth."

Whether or not objects on earth are visible from space depends, of course, on the distance from the planet. At several hundred kilometers from earth, we have seen things about our planet not visible from the normal human perspective. The Eye of the Sahara is one of these features that remained hidden until the advent of space photography.
Officially named the Richat Structure, the Eye of the Sahara was first described in the 1930’s. The geologic structure is a prominent circular feature in the Sahara's Adrar Plateau in west-central Mauritania, in North West Africa.
Because the location is remote and inhospitable, no one had paid much attention to the geological find since the 1940s until it was photographed from space. These photos rekindled interest. At first geologists thought it was a crater, but the more recent and accepted theories suggest that it is, in fact, an eroded dome 25 miles in diameter, exposing sedimentary rock in layers which appear as concentric rings. A product of erosion that took place in geological time. Photos of the area may flutter the heart of a geologist, but they don’t impress the average person. ▼Photo Source: excitementnnet.blogspot.com/eye Photo Source: en.wikipedia.org/Richat_Structure ▼
I didn’t think so.
Apparently, no one else was either – at least enough to do more research in such an inhospitable location.
Seen from space, however, the photographs look like this.

Now that there’s a realistic movement and investment to send tourists to space [not in my lifetime – Boo-hoo!], no doubt humans will discover many more mysterious and wonderful things about our planet. Unfortunately, The Eye of the Sahara will not be on anyone’s bucket list for a while – at least until there is tourist travel in space.
