Earth Science Online Resources
Fire Newton's Cannon and see how satellites orbit, or fail to orbit, Earth.
You can see satellites just about every night, including the International
Space Station, without a telescope. This site tells you when and where to look.
The site to see if you're interested in space exploration. So much it would
take months just to see it all!
Experience the moon just as the astronauts did - almost as you were there.
View interactive QuickTime VR Panoramas in full-screen from the 6 Apollo
Missions who landed on moon.
A history of manned lunar spacecraft. A NASA site.
Ever wonder how they do it without stuff floating all around?
This web page is designed to give everyone an idea of what our universe
actually looks like. There are nine main maps on this web page, each one
approximately ten times the scale of the previous one. The first map shows the
nearest stars and then the other maps slowly expand out until we have reached
the scale of the entire visible universe.
A cool little movie showing the moon as it goes through its phases.
This page contains a summary of all eclipses of the Sun occurring between 1999
and 2020. Full details, including maps, are provided for all significant eclipses.
Everything you ever wanted to know about eclipses.
A great little site about the early history of astronomy. Cool movies that
show how retrograde (backwards) motion is explained in both a heliocentric and
a geocentric universe. Also shows Kepler's 1st and 2nd laws. There's also a
little movie explaining parallax, the only way to actually measure the
distance to stars.
Archaeoastronomy's goal is to understand how skywatchers of the past fashioned
and refined systems for regulating their primitive calendars and for
memorializing celestial events, both cyclical and unique.
Before the arrival of Europeans, the Maya culture of central America were
already accomplished astronomers. See what they knew, you may be surprised.
This website is an overview of the history, mythology, and current scientific
knowledge of the planets, moons and other objects in our solar system.
Views of the Solar System presents a vivid multimedia adventure unfolding the
splendor of the Sun, planets, moons, comets, asteroids, and more.
All the facts you'd probably ever need about the planets. From the good folks
Want to know more about the Red Planet? Lots of information and images here.
This mission is going on right now, and will arrive at Pluto in 2015. The
probe has already made discoveries as it passed by Jupiter in Feb. 2007.
Animation made with NEAR space probe images, not a cartoon!
Amazing little movies of our sun, taken by astronomers at the Big Bear Solar
Images of the sun taken by the Transition Region and Coronal Explorer. Amazing!
Awesome images of our sun. And you thought it was all nice and friendly.
See how small and how big things can be, from subatomic particles to the edge
of the visible universe, on this interactive size scale.
This great site can generate a customized star chart for just about anywhere
in the world, including here. I chose St. Petersburg for a nearby city, and
got a nice choice of star charts. If you click on a planet symbol (on the
"Explain symbols on the map" page) you get a cool profile of the planet that
even includes music!
A viewers guide to the night sky, including constellations, planets, eclipses,
and meteor showers.
An excellent site to learn about the constellations. Check out the
interactive star chart (make sure Java is enabled on your browser), it's
Nebulae are among the most beautiful objects in the universe, and this site
has some great pictures of many of them.
An interactive view of the stars. It's almost like having your own observatory!
The best pictures of the cosmos ever seen by humans.
The best images from the Hubble Space Telescope.
A close, interactive look at perhaps the most incredible picture ever taken.
Thousands of galaxies in a very small part of the sky where your telescope
wouldn't see a thing.
This free download shows you where we are in the Milky Way galaxy, and where
many other objects we see in the night sky are located. Zooms, scrolls, and
has great filters. Takes a few minutes to download, but totally worth it.
One of the very best, most complete Astronomy sites.
Animations of just about any concept in Earth Science.
This is a HUGE site with all kinds of pictures, videos, animations,
simulations, games and more.
There's a lot of bad astronomy out there - the "face" on Mars, NASA
faking the moon landings, UFO's, astrology, etc. On this site, Phil Plait
examines the "evidence" supporting these pseudoscientific claims.
Images and basic facts about planets, moons, constellations, galaxies - lots
of great stuff.
