About This Category

This collection is of free images/photos/pictures, sounds, videos, etc from science, technology and nature, including birds, animals and plants, and some from the fields of chemistry, physics and biology. Some exhibits that could be in here may be found in collections with a more specific remit, such as "Flowers" and "Leaves and Greenery".

This is intended to serve, in part, as a teachers' and students' resource.

See also New Scientist for the latest news, The Register's science and tech stories, the EurekAlert!/AAAS Multimedia Gallery, and BioImages - Virtual Field-Guide (UK) for scholarly info.

Also, for attempts to catalogue all known species, see: the Encyclopedia of Life, and Barcode of Life.

If you're a journo or other non-scientist and need help with a science fact or story, please consider talking to Sense About Science to help you.

  • vlt = Very Large Telescope = The Very Large Telescope (VLT) is the world's biggest optical telescope. It has four 8-metre telescopes and four 2.4-metre Auxiliary Telescopes (ATs). They sit on a flattened mountain top at Paranal in Chile. They use adaptive optics to eliminate some of the effects of turbulence in the atmosphere, and when they can't use a bright star they create their own by shining a sodium laser upwards to excite sodium ions in the ionosphere---the laser guidestar. See site information on the ESO at Cerro Paranal.
