When Apollo 11 astronauts returned to Houston 35 years ago, they brought 40 pounds of lunar rocks and soil. Today, the collection they started also contains pieces of Mars and cosmic dust. And in the coming years, it will add particles of the Sun and a comet -- and perhaps more pieces of the Moon and Mars. Learn about this repository for cosmic loot in our September/October feature story "Chips Off the Old Solar System." Also, learn how to take astrophotos from your backyard in "Adventures After Dark."
