What do you see in this APOD? There is a goodly amount of response to the Earth geographic challenge in the discussion thread but I thought it might be interesting to discuss other aspects of the image. What do you see... beyond the pale perhaps... beyond the image... embedded thoughts anyonePersonally, I think this may be the best APOD yet.
Here are some posts from the image discussion along this line...

But at the same time, this image speaks of how closely bound we humans are to the Earth. Yes, we have travelled 350 kilometers away from the surface of the Earth, and we have travelled even farther - humans have, after all, walked on the Moon. But the distance to the Moon, while more than a thousand times greater than the distance to the International Space Station, is still only about 450,000 kilometers. In the universe, where most distances have to be measured in lightyears or better yet, in kiloparsecs or megaparsecs, 450,000 kilometers is nothing.
I once saw a black and white movie that may have been from the early forties. Here some brave humans were struggling heroically to make their spaceship overcome the Earth's gravity. But once they had climbed out of the Earth's gravity well, the universe was literally theirs for the taking. They could go anywhere, to Mars, to Saturn, to Sirius, because they were no longer bound by the Earth's gravity.
But that is not how it works. We are so incredibly bound to the Earth, this little blue speck in the universe that sustains us, and that hosts all the life that we know of.
