Earth Pictures

I was almost done posting for the day, but then I found more unbelievable space pictures.  The twist?  These ones are pointed at the earth.

It always blows my mind that these kinds of images are real as opposed to created by by Photoshop or something.  And as always, there's something to be learned from the color composition and arrangement and such.  There's a reason they're so visually appealing, after all.
