It is hard to believe, but some of the smallest organisms on our planet can be viewed from space. Diminutive bacteria and plankton (microscopic, floating plants) can merge into great chains and mats that can be detected by satellites hundreds of kilometers up.

NASAs Aqua satellite captured this image of a plankton or bacterial bloom south of Fiji on 18 October 2010.
