It’s a spectacular image. Click to view in full resolution!

But the projection is slightly…unusual. Can you pick why this isn’t what the earth would look like if you were viewing it from, say, the moon?

    Ah, it’s quite a wide-angle view, is it not? Looks like the farthest north point is (roughly guessing) Southern Canada, while only the tiniest portion of Antarctica is visible. If viewed from the Moon or any other relatively distant location there would be much more surface area visible.

    I figure its a fish-eye lens, extremely well-centered.

    The perspective is wrong, because the moon is actually located in a studio in Nevada?
