Reference Shelf Welcome to the Reference Shelf! The Reference Shelf is a list of pages on the World Wide Web that contain basic information about the solar system and Shoemaker-Levy 9, with links to lots of other pages. Think of it as a shelf full of multimedia "books" that you can use when you do your research. To start using any of these resources, just click on its name. The Nine Planets At this site, you can take a tour of the solar system, stopping to read about each of the planets as well as experience some of the sights and sounds related to each planet. Glossary of Astronomical Terms This is part of Bill Arnett's page The Nine Planets. It has definitions of terms ranging from accretion to zodical light. JPL's Jupiter Profile The Jet Propulsion Laboratory works closely with NASA in exploring the solar system and provides a great deal of information about its research on the Internet. This page is full of facts about and images of Jupiter. Comet Shoemaker-Levy 9 Collision with Jupiter Some parts of this page were created before Comet Shoemaker-Levy 9 -- or "SL9" -- collided with Jupiter. Other parts of the page have been updated more recently. (It might be interesting to compare predictions to what actually happened.) There are links to many other sites, including places to find images of the impact. National Space Science Data Center's SL9 page The NSSDC provides detailed information about the comet and the impact, with links to images from many different sources, including the Hubble Space Telescope. Space Telescope Science Institute STSI maintains this page, which includes information about the data collected in the months after the comet's impact. JPL's SL9 Home Page JPL's site devoted to Shoemaker-Levy 9 is perhaps the most extensive, and it has links to some other excellent SL9 sites. Its Latest Conclusions section has links to magazine articles on the topic. Comet Shoemaker-Levy 9 This site gives specific information about several fragments of Comet Shoemaker-Levy 9. The impact images are unique and the information is very interesting. Tribute to Eugene M. Shoemaker This site pays tribute to Eugene Shoemaker, the discoverer of SL9, who died in 1997. A portion of his remains was sent to the moon for burial. Search Engines You can search the Web for information by going to a search engine site and typing in a key word or phrase (such as "Jupiter" or "Shoemaker-Levy 9"). The search engine will return a list of Web sites that relate to your key word(s).
