Do you know our Earth didn’t appear blue in NASA’s first satellite images! But times have changed. Look at this “Blue Marble 2012” – as NASA (US government’s National Aeronautics and Space Administration) calls it and claims it to be the most amazing high definition image of Earth so far.

Earth as a ‘Blue Marble’ was first snapped by the crew of Apollo 17 in 1972 and that image has always been one of the most famous photos ever taken, for we all then suddenly saw the world in a much different way.

In the years since, the space agency has added many blue marble laurels to its credit, of course with technology enhancing and sharpening the so difficult to take images. And as the latest photo is released, NASA says it’s the most amazing high definition image of Earth.
