Kepler Starwheel

Uncle Al's Star Wheels are inexpensive star maps, adjustable for any time of night in any month of the year. Such maps are also called planispheres. These star wheels were created by the Hall's Hands-On Universe project, and based on the Lawrence Hall of Science (LHS) Sky Challenger, a set of 6 star wheels, formerly available through the Hall's Discovery Corner Store.

Kepler Exoplanet Transit Hunt

Kepler Exoplanet Transit Hunt lets you discover a planet by the “transit method” like what the NASA Kepler Mission used: watching a star and hunting for the tiny drops in brightness that happen when the planet passes (transits) in front it! How many properties of the planet do you think you can know just from a few minuscule dips in brightness?
