That is beautiful, although it's a little scarey to see how thin the atmosphere is compared to the Earth. Standing on the ground, I tend to think of the atmosphere as "going up forever," while I'm not conscious of the "depth" of the Earth. I remember the first time I actually calculated the actual values, apprehensive at just how thin the atmosphere actually is. Thanks for posting this!
