From deep within the human body to distant nebulae in outer space, there are worlds all around us that are smaller, faster, and farther than the unaided eye can see. In these thirty-six amazing images, you can see the invisible: from a white blood cell attacking E. coli bacteria, to the delicate splash from a falling drop of water captured by a high-speed strobe.

With pictures that astound and fascinating explanations of how each image was captured, award-winning author Seymour Simon takes readers on a fantastic voyage that's truly out of sight.
