Carleton College: Goodsell Observatory: Goodsell Observatory's Astronomy Links

Goodsell Observatory's Astronomy Links

There are a large number of great astronomy web sites on the internet and while we would like to be able to list them all, doing so would be next to impossible. We, therefore, have listed only our favorite sites. These include sites which we often use in astronomy classes/labs and public open houses as well as sites which are relevant to the astronomy and astrophysics program here at Carleton College.

Although we cannot list all of the web's astronomy sites, most of the sites listed on this page have a "links" page of their own. It is thus our hope that you will use these links as a jumping off point from which to explore the world of online astronomy.

Also available are some pages of links developed by students as part of special projects. These expand on the links below, focusing on certain topics or intended users.

Sun-specific links

Links geared towards teachers, students and kids

Keep in mind that we designed this page to be browsed rather than used as a quick reference for finding specific information. In order to provide some organization, however, the links have been loosely arranged into different categories. We have also provided a short description of each link and in many cases these descriptions include sub-links which highlight a certain part of the main site being described. Enjoy!

Exchanged

From time to time we receive requests to exchange links with another web site. If you would like to exchange links, please contact us.

Universe Today: This site published by Fraser Cain offers a daily collection of space related news gathered from around the internet. Check it out!

Observatories

Arecibo Observatory: Carleton astronomy professor Joel Weisberg has taken many Carleton students (and still does) to Arecibo to collect data. Check out the observatory's general public page.
NOAO - National Optical Astronomy Observatories: The NOAO overseas a couple of large optical observatories including KPNO - Kitt Peak National Observatory where Carleton astronomy professor Cindy Blaha and students have gathered data.
NRAO - National Radio Astronomy Observatories: Like the NOAO, the NRAO overseas a number of radio observatories including the VLA - Very Large Array where both Cindy and Joel have taken data. Take a look at NRAO's Introduction to Radio Astronomy page to learn about the basics of radio astronomy.
Royal Greenwich Observatory: The Royal Greenwich Observatory on the Royal Museums Greenwich website
USNO - United States Naval Observatory: The USNO is the place to check what time it is! They maintain the United States master clock and used to do so via their own time service, similar to the one that was operated here at Carleton College. Browse the Time Service Department for more information. Take a look at the USNO Astronomical Applications Department for moon and sun rise and set times. A large part of the observatory's job is to do Astrometry to determine the positions and motions of celestial objects.

Research

NASA ADS - The NASA Astrophysics Data System: ADS is an excellent spot to do astrophysical research from. This NASA-funded project is a huge bibliographic database for millions of papers from many many publications.

Societies

AAS - American Astronomical Society: North American organization for "astronomers, other scientists, and individuals interested in astronomy." The AAS held their 34th meeting at Goodsell Observatory in 1925.
