I've always loved Astronomy ... in fact, I used to teach it at Georgia State University, and I was a volunteer in the Astronomy Department at Fernbank Science Center in Atlanta for many, many years (and I still am now and again!). There are far too many Astronomy resources on the Web to list them all, or even a representative sample. Still, here are some of my favorite Astronomy links:

This Web site presents data from the Sloan Digital Sky Survey, a project to make a map of the entire universe. We would like to show you the beauty of the universe, and let you share our excitement as we build the largest map in the history of the world. Sky Server presents more data from the Sloan Digital Sky Survey.

This is the first of several planned Web sites devoted to presenting information on human exploration of space. The series starts with this Virtual Tour of Mars called ExploreMarsNow. Explore the planet with realistic Mars habitats, rockets, ground cars, and robots. Here are Eight Wonders of the Solar System. Just wow.

Speaking of wow, check out this
3D representation of what the Hubble Space telescope found when pointed at a patch of dark, “empty” space. That is brought to you by the folks behind one of my favorite sites: Deep Astronomy.

The Astronomy Net is a collection of helpful resources for everyone interested in the science of Astronomy.

Click here or here to take a look through the Hubble Space Telescope. And here are the 20 best Hubble pictures. That's quite a claim, but it's hard to argue. Here is the amazing complete Hubble gallery.

The Astronomy Picture of the Day is always breathtaking. Here you can see our fragile planet Earth from space.

Dark spots, some as large as 50,000 miles in diameter, move across the surface of the sun, contracting and expanding as they go. These strange and powerful phenomena are known as sunspots.This resource will allow you to explore the nature of sunspots and the fascinating history of efforts to understand them. Included here are interviews with solar physicists and archaeoastronomers, historic images, modern NASA images and movies, and a sunspot research activity.

Here is a great index of Astronomy sites on the Web. Maybe it's the romantic in me, but I like this site on Astronomical facts, trivia, and folklore.

One of my very favorite sites ever:
We Choose the Moon is an interactive virtual recreation of Apollo 11’s historic mission, created in celebration of the 40th Annoversary. This is NASA's page on the Apollo missions.

Wonder what it's like to walk on the moon? Join the Apollo astronauts on the Lunar surface in
this series of stunning 360-degree panoramas, one each from the six successful Apollo moon landings. Shot by the astronauts themselves during their historic moonwalks, these images capture the magic and mystery of the moon.

This site is as close as most of us will come to flying aboard a NASA
Space Shuttle. Click here for NASA's mission to Saturn.

What would the Sun look like if you were standing on Saturn? How about if you were standing on one of Saturn's moons? Or on Neptune? Or .... Become an armchair astronaut and take a virtual journey through our galaxy with
this site developed by NASA, JPL, and Caltech. Date ranges allow you to travel as far back in time as the 17th century and as far ahead as the 24th, and additional options track constellation lines, planetary orbit paths, and more.

This site by NASA and the Jet Propulsion Laboratory details their search for another Earth with light-seeking interferometers, interstellar telescopic wizardry, and scientific passion that aims to rejuvenate space program.

Here you can enjoy a really terrific virtual planetarium. Browse some photos of a Lunar Eclipse.

The Universe Within begins by showing the Milky Way Galaxy from 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. This is one of the coolest sites out there. Here is an earlier expression of the same idea.

Check out this 3D Guide to the Galaxy from NASA.

This site features the top ten weird wonders of outer space, from black holes and brown dwarfs to electrostatic levitation.
