Supernova explosion. Image 1 of 4. Supercomputer simulation showing a supernova explosion 50 milliseconds (thousandths of a second) after core collapse. Supernovae occur when a massive star has run out of nuclear fuel and its core collapses to form a neutron star. The collapsed core triggers a shock wave that powers the supernova explosion. This simulation shows the entropy (amount of disorder within a thermodynamic system) of matter (light areas) that is rising due to heating by neutrinos at the core (unseen). The heated matter rises and mixes with in-falling cold matter (dark areas) resulting in turbulence. It is thought that neutrino-driven convection energy accompanies the shock wave to power the supernova explosion. Simulation created...
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.
