Now that the rover Opportunity has spotted the residue of martian puddles, you might be eager to learn more about the Red Planet and the rest of the solar system. Take a jaunt through our neighborhood of space with the nifty graphics on NASA's home page for solar system research. Aimed at students and the public, the site profiles the sun and planets, explaining, for example, why Mercury has such a paltry atmosphere (the planet's high temperatures cook most of it away) and why Uranus is lying on its side (it might have toppled over after crashing into another hefty object). Crammed with photos, animations, and videos, the site's gallery spans 6 decades, from the early rocket designers to this year's shots from the surface of Mars. Visitors can also read about NASA missions such as Galileo, which snapped a false-color photo of our moon in 1992 while traveling to Jupiter.
