A wide belt of asteroids lies between Mars and Jupiter, and was formed at the same time. If these asteroids had come together to form a 10th planet, what would it be like? Students investigate the answer.
Did it all start when an apple bopped Isaac Newton on the head? This activity explores some of the ways his fundamental laws are expressed in our dynamic solar system.
Throwing water balloons on school grounds in the name of science? Absolutely, if you do it safely, and apply what you learn to the science of finding and recovering meteorites.
How do you find a place that's been lost for more than 300 years? Take up this challenge, and learn what it took for archaeologists to locate a lost mission on a 14,000-acre island near Georgia.
It's not easy being an artifact! There's restoration work, touring schedules, and all those people to educate. Uncover a civilization that flourished long before the Aztecs in this urn-est interview.
It's your turn to do archaeology! As you investigate what daily life was like in the Inca empire, you have the chance to collect Inca chronicles. Do you have what it takes to collect all six?
One person's trash is another person's clue. It's amazing how much you can learn about people just by examining what they throw out. Grab a thick pair of rubber gloves, and dig in!
In the future, if archaeologists were to dig up artifacts from your life, what would they find? What would these objects tell them about how you lived? Build your own time capsule, and send a tailored message to future generations.
Have you ever gotten lost in a new place? Chances are you used a map to find your way. Archaeologists use maps to find their way around an excavation site—but first they have to draw them.
Astrophysicists are discovering new extrasolar planets—those outside our Solar System—almost daily. NASA's Spitzer Space Telescope (originally called SIRTF, or the Space Infrared Telescope Facility) and AMNH's Lyot Project Coronograph are two of the many technologies uncovering the attributes and evolution of these faraway worlds. The techniques employed by these instruments may one day help answer one of astronomy's reigning mysteries: do any extrasolar planets host life?
The feature video relates scientists' hopes for the Spitzer Space Telescope before its launch in 2003. It also gives a firsthand look into the making of the Lyot Project. The feature essays share how these two remarkable technologies are making progress in their goals to seek and understand extrasolar planets.
