The world in a drop of water

Well, a man's head, actually.

I'm grateful to Ethan Siegel over at Starts with a Bang for posting these pictures of Pedro Duque during his time on the ISS.

So what's going on here?  Answer, the blob between the camera and the man is actually a droplet of water, which, under zero gravity, has become almost perfectly spherical.

The image is inverted because of the simple optics going on, and the camera has focused on the droplet, not the man, so you see Pedro slightly distorted, viewed through a spherical, water lens.
