The Messier Gallery
A collection of images of objects in the Messier catalog.
This is a brief list of usefull sites with Astronomical, Astrophysical or Cosmological Information. Some of these are just "pretty pictures", but many are actually full of information, at various technical levels.
Astronomy Resources This is a good starting point if you want to branch out on your own.
Hubble Space Telescope Pictures Wonderful images of current research in Astronomy and Astrophysics. Each comes with a caption, and sometimes additional technical information.
Photographs by David Malin Excellent photographs taken from the Anglo-Australian Observatory by probably the foremost astronomical photographer in the world.

The Supernova Cosmology Project at Berkely and Harvard
The Solar Neutrino Problem An up-to-date page at the University of Pennsylvania describing experimental and theoretical progress on one of the most important problems in physics.
COBE: The Cosmic Background Explorer Anisotropy in the universe as measured by the cosmic blackbody spectrum.
MAP: The Microwave Anisotropy Probe A planned space based measuremnt of the cosmic blackbody radiation anisotropy,
LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) project home
page. This is a major effort to detect gravitational waves.The Princeton Pulsar Group Includes information on pulsar research at Princeton. This page has some recordings of pulsar "sounds". A suitably equipped workstation will allow you to listen to them.
National Radio Astronomy Observatory Home Page National Radio Astronomy Observatory including pointers to Green Bank, Kitt Peak and the VLA.
Radio Astronomy Home Page The Arecibo Radio Observatory.
Jodrell Bank Home Page
University of Manchester, Jodrell Bank Radio Observatory.
Caltech Astronomy They operate Palomar Observatory, Keck Observatory, Owens Valley Radio Observatory, Big Bear Solar Observatory and the Caltech Submillimeter Observatory.
Dark Matter The center for particle-astrophysics at Berkeley. It has a good bibliography at the end.
Black Holes and Neutron Stars Simulated trips to compact objects. Experience the effects of high gravitational fields. Good technical description.
Large Scale Structure
Images of large scale structure from a number of red shift surveys.
Primordial Astrophysics The Cosmology research group at Carnegie-Mellon University.
Electronic Textbook on Astronomy This is an interesting project at the University of Oregon to create electronic teaching tools for Astronomy. The links are useful, including some data for students to analyze.A set of notes on Astronomy An Astronomy textbook on the Web.
