- Cosmology-Related Applets: Includes demonstrations of
- New Galaxy Collider
- Fusion in the Sun
- Big Bang
- The Sun: Hit the "Sun" link in the text to access this introduction to the sun, which includes information on how the sun creates energy, the sun's various layers, and the sun's vital statistics. Also included are a wealth of linked images and movies.
- Binary Stars: This site provides links to both basic and advanced theory governing binary stars. The site also includes a lecture on binary stars, some student problems, and several Excel Spreadsheets that model binary star behavior.
- Supernovae Remnant Statistics: This site gives a list of many known SNRs, or supernovae remnants. With each specific SNR, the site lists the location, luminosity, type, corresponding literature, and more.
- Questions in Cosmology: This site run by NASA details a few of the most pressing questions in cosmology today: what powered the Big Bang, what happens at the edge of a black hole, and what is dark energy. The Beyond Einstein program aims to work towards answering those questions.
- Pictures of Space: This site provides an index of pictures mostly of galaxies. Pictures range from Messier objects and interacting galaxies to clusters and deep field pictures.
- Stellar Evolution: This exhibit from the Hubble Space Telescope website describes a star's life from birth to death and includes detailed pictures and a movie. The extensive library of links for each piece provides further information.
- Galaxies: This exhibit from the Hubble Space Telescope website shows a typical spiral galaxy like our own Milky Way. Also, the site shows two galaxies colliding and a picture of a black hole like the one believed to be at the center of most galaxies. The extensive library of links for each piece provides further information.
- Dark Matter Candidate Eliminated: The press release from 1994 shows one of the many refutations of possible candidates for dark matter. The Hubble Space Telescope helped to rule out red dwarf stars as possible solutions to the dark matter conundrum.
- Pictures from the Hubble Space Telescope: The gallery at the Hubble Space Telescope website shows pictures of planets, stars, galaxies, nebulae, clusters, supernovae, and more.
- "Planetary Nebulae": This gallery shows a number of pictures of so called planetary nebulae, referring to dying stars shooting off layers of gas in a spectacular explosion.
- Tale of a Supernova Discovery: This provides an interesting story about the discovery of a supernova as it occurred and was recorded. The supernova, named 1987a after the year it was discovered, was the closest observed supernova since 1604.
