Chicken's egg outer shell detail, coloured scanning electron micrograph (SEM). Hard-shelled eggs are produced by birds and some reptiles. The shell protects the growing embryo inside. The holes or micropores which can be seen in this image, enable gaseous exchange of the developing embryo. Most of the egg shell material is calcium carbonate which accounts for about a tenth of the egg's weight. Magnification x4156 at an image size of 10cm wide.
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
