Supernova explosion. Image 1 of 4. Supercomputer simulation showing a supernova explosion of a 15- solar-mass star 0.05 seconds 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 bubbles of hot, buoyant gas (light brown), 400 kilometres in diameter, that envelope the neutron star (unseen). In-falling cold gas bubbles are heated by neutrinos at the core. The heated gas rises and mixes with more in- falling cold gas resulting in turbulence. It is thought that neutrino-driven convection energy accompanies the shock wave to power the supernova explosion. Simulation...
About the Artist - Leonhard Scheckkonstantinos Kifonidismax Planck Institute For Astrophysics
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.
