MicroWorld: Fantastic Voyage with Scanning Electron Microscopy.

Flickr user Reciprocity has a fantastic narrative for MicroWorld photoset, where the scanning electron micrographs of various crystals serve as out-of-this-world settings of an exploration of some strange planet.

This one above is an electron micrograph of tin oxide crystal – the width of the image is 30 microns, or half the thickness of a human hair.
