This is a quick directory to astronomy websites which cover a broad
range of topics in some depth. I wrote this quickly to replace the more cumbersome list that
was previously here. I have arranged the
links according Beginner/Introductory,
Intermediate / Early Undergraduate, and
Advanced. Some in one category may be suitable in another.
That depends on you. There is also something very brief for
Elementary School Level, which I prefer to consider separately.
Although astronomy is definitely covered in elementary school curriculums, I have
not tried to focus on that level. There is only so much I can do. A number of
beginner websites exist on the Internet. But in my judgement, some of those are not
necessarily good starting points for really learning astronomy in school. In my
judgement, even some NASA kids websites fall short. Therefore, I would rather leave
this category open, than quickly list links.
I do have a section Astronmy Links Especially for Young Minds.
In general those links are on a grade school level. However, I consider most of those
links more as enrichment than as reference material.
That said, if one is comfortable enough to really play with the science, the distinction blurs.
An individual may begin to realize out of one's own growing what makes good science learning.
An aspect I consider is: does the
child have the chance to feel the questions of the subject? There is a deep difference
between learning a subject from its questions versus just learning the answers.
I will list here just a small set of links suitable perhaps for elementary school level.
I do want to point out, as I revise the website, I will try to do the following:
At the beginning of sections on other pages, if I find links that I think
are suitable for elementary school level, I usually will place them at the beginning of the
section and identify them.
-
Leicester University Guide to Space
-
Curious About Astronomy?
Cornell University.
A university level introduction. Plus basic and intermediate level Q&A.
- Astronomy Cafe
Sten Odenwall.
-
Prof. Gene Smith's Astronomy Tutorial
Based on an introductory college course for liberal arts majors. Includes some physics
details (astrophysics).
University of California, San Diego Center for Astrophysics & Space Sciences
-
Astronomy 108 The Astounding Cosmos
Survey of modern astronomy course for non-science majors. Includes a taste of the math.
Dr. Joe Howard.
He also has a slightly more advanced class,
Physics 317 -
Astrophysics and Stellar Astronomy.
However, the notes there are not as easy use if you're not
taking that class. Salisbury State University, Maryland.
-
Introductory Level Astronomy Supplemental Pages
by Kristen and Scott Miller, University of Marland.
- Dr. Siobahn Morgan.
(Thank you for writing me.)
Univ. of Northern Iowa.
-
Nick Strobel's Astronomy Lecture Notes
- University of Tennessee, Knoxville:
-
Astronomy 103
J.C. Evans. George Mason University.
The
astronomy supplement has extensive discussions.
- John F. Hawley. University of Virginia.
- Sloan Digital Sky Survey Education Projects
Basic and more advanced (intermediate) levels.
- A Review of the Universe
- National Aeronautics and Space Administration (NASA)
The U.S. aeronautics and space agency. Almost any space topic can probably be found through
the NASA websites.
-
From Stargazers to Starships by Dr. David Stern, NASA GSFC.
Dr. Stern says that he wrote this for a high school level. Includes high school level math
and math review.
- Imagine the Universe
A website about astrophysics for teen level and above. High energy astrophysics is particularly
emphasized. However other aspects are covered as well.
Note there are several levels of presentations. There is more material here than is
obvious; therefore I suggest using the sitemap. Includes links to more resources at universities
and book suggestions for high school or university level.
High Energy Astrophysics Science Archive Research Center @ NASA GSFC.
- Cool Cosmos

Associated with the Spitzer Infrared Space Telescope, Cal Tech / JPL.
Although the website's focus is especially infrared astronomy, its
resources cover many general astrophysics topics. In Engish and Spanish.
- Hubble Space Telescope Web Sites (NASA, ESA, and AURA.)

Not as much deep information as they used to have.
