ViewSpace Interactives: Detecting Other Worlds

Scientists have detected thousands of exoplanets: planets orbiting stars other than the Sun. We have seen only a few exoplanets directly, but we can detect them by measuring the effects they have on the stars they orbit. Understand the techniques scientists use to learn about these distant worlds by clicking through a progression of stops featuring HAT-P-7 b and the exoplanets orbiting star HR 8799.

Our interactives and individual videos may be accessed by anyone; however, for informal learning venues that would like to present the ViewSpace looping video collection to the public, please request a free account.
