Sky Watching and Amateur Astronomy
The Astronomy Section of the Rochester Academy of Science is a friendly group whose volunteers operate the Planetarium telescope. They welcome beginners at public star parties and other events through the year.
If you hear about a meteor, sunspot, solar storm, eclipse, or any other short-lived celestial phenomenon, check here for information and pictures.
When is the next eclipse and where will I have to go to see it? Check here for the answer. NASA expert Dr. Fred Espenak maintains detailed information on solar and lunar eclipses — past, present, and future.
The U.S. Naval Observatory is the authoritative source for celestial calculations. Their Astronomical Applications Department makes all this information available to you, customized for your location and date.
When will the International Space Station or any other large satellite be visible in Rochester’s sky? This German commercial site tells you when and where to look and can even create sky maps.
Found a strange rock? Think it’s a meteorite? Professor Korotev in the Washington University Department of Earth and Planetary Sciences is here to tell you it almost certainly is not (but you can always hope)! Many pictures of meteorites and “meteowrongs.”
Have you seen strange and beautiful shapes or colors in the sky, especially near the sun, moon, or bright stars or planets? This site offers pictures and explanations of all kinds of sky effects related to clouds and atmospheric conditions.
A rich treasure of images, maps, and articles based on data from Earth-observing satellites such as Terra and Aqua. Explore topics such as atmosphere, heat, land, life, oceans, snow and ice, and human presence.
Millions of photographs of Earth taken by astronauts from the Mercury missions of the 1960s to the present. You can search by place name, by clicking on a map, by mission, or by NASA photo number if you happen to have it. You can also request high-resolution versions of most of the recent pictures by clicking a button and waiting a few minutes.
This site is loaded with data and details, as is appropriate for the complex topic of climate change. Headings include evidence, causes, effects, key indicators, and uncertainties.
Our Solar System
An overview of the history, mythology, and current scientific knowledge of each of the planets and moons in our solar system. Each page has text and images, some have sounds and movies, and most provide references to additional related information. Especially helpful if you want to get to a specific fact quickly.
Different from The Nine Planets (listed above), emphasizing how we learn about our solar system using telescopes and space probes. This site also includes information pages on the planets, major moons, and small objects, in a different style.
Pictures of the sun, taken from space, updated several times a day. Follow the progress of sunspots and solar storms as they happen!
Check here for reliable information on space objects that come near Earth.
The Planetary Society is an advocacy organization that campaigns for solar system exploration missions, but their website also includes a fine selection of news items, pictures, and informative articles.
Other Solar Systems
Both of these sites document the search for planets orbiting stars other than our sun. Much of the information is meant for professional researchers and those who want to analyze statistics, but you can find introductory information if you explore a bit.
If you’re interested specifically in stars (as distinguished from galaxies, planets, meteors, etc.), this site is loaded with useful information. Dr. Kaler, a leading expert on the subject who maintains the site, spoke in the RMSC Distinguished Scholars Lecture Series in 1995.
Big Bang, Cosmology, Etc.
By measuring the heat left over from the “Big Bang,” the WMAP satellite is providing epoch-making information about the very early universe. From the home page, click on “Universe” to get “Cosmology 101,” an excellent overview of the Big Bang picture and the evidence for it.
Maintained by a UCLA astronomer, this site uses science and math at about high-school level. The “News of the Universe” and “Frequently Asked Questions” sections are especially good.
