There is also this image, taken through the left-hand command module window of Apollo 4:
Perhaps the first US image of the whole Earth, but not widely published.
The more I look at real (and well-compiled) pictures of the Earth, the less I think this image should even be given the title of "Blue Marble". Maybe I'm missing out on the high-res version or something, but for something to be a spectacular image it should look great even at fairly low resolutions.
Also, consider that on so many maps Europe is put in the center. Europe has been just as guilty as North America of making their continent look bigger or more important. Heck, I'll bet this is done on every continent.
Well, the Mercator projection will make landforms nearer the poles much larger than ones at the equator (see Greeland being of equal size to Africa, whereas in reality it is far smaller, for example). It's just a matter of cartographic technique.
And of course with a Meridian located in Europe (Greenwich, of course) it does put Europe roughly in the center of the map.
To me, Africa has always appeared in the center of a world map centered on the Greenwich meridian. It is relatively close to the meridian, and it straddles the equator. It is not flanked by considerable landmasses directly to the east or west... so it really stands out at its position on the map.
Perhaps it is appropriate, considering that we all came from Africa. :lol:
