Introduction

Astronomical information has been available online since the early days of the Internet. Physicists were early adopters of the Internet and the web, and astronomers were not far behind. For example, when comet Shoemaker-Levy 9 struck the planet Jupiter back in July 1994, images taken of the event were immediately put onto the web. People from all over the world could see the images as soon as they were posted, and professional astronomers could immediately download scientific data. This was one of the first major scientific events that demonstrated the power of the Internet and the ability of the astronomical community to share scientific images and data quickly with the public (Egret and Heck 1994).

Many astronomical organizations have been ahead of the curve in utilizing the Internet for electronic publication. "The physics and astronomy communities have been among the first involved in EP [electronic publishing], even before the concept itself existed per se. Astronomers, space physicists, high-energy physicists and their colleagues around the world have done more than just help in setting up the Internet and the associated networks. They jumped onto the World-Wide Web (WWW) and quickly became prolific producers and eager consumers..." (Heck 1997). "Traditionally, astronomy has been on the forefront of using computer-based tools and systems; in particular, astronomical publishers developed and implemented new publishing procedures well ahead of publishers in other disciplines..." (Grothkopf 2000).

Astronomy and astronomical information can be divided into two groups. For the most part, there are web resources for professional astronomers and web resources for amateur astronomers. However, there is a strong link between the amateur and professional community. "...There is no well-defined boundary between professional and amateur astronomy, and the latter can be of vital use to professionals, e.g., in the field of variable stars, comets or solar system events. Indeed, stellar photometry--a field traditionally dominated by amateur observers--boasts a database of variable star observations ... that is the envy of many professionals..." (Andernach 1999). (The URL for the database given in the book has moved to {http://www.aavso.org/adata/database.stm}.)

Worldwide, amateur astronomers greatly outnumber professional astronomers. "Estimates of the total number of amateurs in the U.S. range from 200,000 to 500,000, often depending on how exactly you define the term. In any case, this figure, 40 to 100 times the number of professional astronomers, represents a tremendous population..." (Fraknoi 1998).

Since much of the funding for astronomical research in the United States comes from the federal government, most of these federally funded projects have an incentive, if not a mandate, to provide outreach to the general public. If a project does not clearly demonstrate its scientific advancements to a lay audience, then the project might not be funded in the future. Also, the NASA Astrophysical Data System has been providing abstracts of astronomical research to the public for free over the Internet since 1991 and over the web since 1994 (Eichhorn et al. 1995). Because of some of these reasons, libraries, their patrons, astronomy students, and amateur astronomers can easily access astronomical information that is created by and for professional astronomers.

Audience, Scope & Methodology

This webliography is written for librarians who serve a scientific or technical clientele, and any person interested in learning more about astronomy and astronomical information services.

The scope of this webliography is to point people to some of the best resources on the web for astronomical research and information. This is by no means comprehensive, and is focused on web sites based in the United States. Some of the annotations for the resources were drawn from the organization providing the resource. Since many of the metasites do not provide much of an annotation nor a description of a resource, a webliography such as this will provide more information about the content of a web site. Not all of the resources will provide full text. For example, the magazine links might just provide a table of contents or abstracts to the papers contained in the printed publication.

Much of the information for this webliography was found by browsing many of the existing web sites, links and pointers that others have provided. Some of the links and resources were found using two reference books listed in the References section (Hurt 1998; Thomas 1998). We also used the search engine Google -- http://www.google.com -- to verify changed URLs for some of the resources. There are so many wonderful web sites concerning astronomy, that is was difficult to pare down this webliography. While we have tried to provide links to resources from stable organizations, there were a few resources provided from an organization's or an individual's web site that might be temporary, but we felt were still worthwhile calling attention to.

Catalogs and Data Centers

An astronomical catalog is a listing or a grouping of astronomical objects by some property. For example, the following are titles of specific catalogs: "Distances of planetary nebulae," "327 MHz survey of the galactic plane," and "Faint Blue Stars in high Galactic Latitudes." A data center usually provides a friendly interface between the user and the raw data. They are web sites that could point to a single catalog or a collection of catalogs, or they could keep data from a particular mission, from a specific instrument at an observatory, or from multiple missions, observatories and catalogs. A data center could also merge bibliographic information with a data archive.

VizieR Service

Amateur

The following is a list of some of the major software products that are used by many amateurs, and by some professionals. Some of these are commercial products, and are usually in the $50-$300 price range. At a minimum, these programs will include: variable date and time range (at least plus or minus 2,000 years from the current date) and the ability to view the sky from just about any location on earth. They can show the position of all of the planets, the Moon, comets, asteroids, thousands or millions of stars and thousands of deep-space objects such as galaxies, star clusters, and nebulas. Extra features might include: an eclipse finder, ability to see the universe from other astronomical objects besides the earth, an ability to download or input data for tracking of new comets, telescope control, and more. When they include more features, more stars, and more deep-space objects, then it will probably cost more.

Observing Programs

By Astronomical Object
By the Wavelength of Observation

One way to categorize observing programs is by astronomical object. Some things that astronomers study include: the Moon, the Sun, the planets, planets outside our solar system (extrasolar planets), comets, stars and their formation, other galaxies, and the whole universe. An example of a web page that points to research done on a variety of astronomical objects is available at the High Energy Astrophysics Science Archive Research Center -- http://heasarc.gsfc.nasa.gov/docs/objects/objects.html.

By the Wavelength of Observation

For Hundreds of years, all astronomical observation was performed in the visual wavelengths of light. But, visible light is just a very narrow band of the electromagnetic spectrum. (If you want to get more information concerning the electromagnetic spectrum, the following web page would be useful -- {http://nvo.gsfc.nasa.gov/mw/mmw_EM.html}.) In the last 50 years or so, with radio telescopes and space based observatories, astronomers have been able to observe astronomical phenomena outside of the visual wavelengths. Observed phenomena now occurs from the shortest to the longest wavelengths: cosmic rays, gamma rays, x-rays, ultraviolet, visible, infrared, microwave and radiowave. An example of a web page that shows astronomical observations recorded by the wavelength (or energy) of light is at the High Energy Astrophysics Science Archive Research Center -- http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/energy.html.

Most of the following observing programs will provide scientific data and results, images, and supplemental information for students and educators. Many of these web sites are at either governmental or educational institutions, so they almost always have a mission to provide educational outreach to the public and to educators.
