It was taken by the crew of Expedition 36 aboard the ISS on July 21st. I've seen plenty of others like it with less cloud-cover, but that's a much more recent (and equally cool) shot.
From the guy who almost always posts a plane pic in here, I think they still have a place in this thread as long as there's actually something cool about it that even non-plane enthusiasts can appreciate, like this.
The video really threw me off, my eyes couldn't figure out what was happening for a bit. Probably because it couldn't believe what it was seeing, and also cause of the size and angle of the camera. Awesome video though.
