This Digi Kit introduces students to the emerging field of exoplanet atmosphere analysis. We've found thousands of exoplanets, but could they harbor life? The Digi Kit explores how scientists use spectral data gathered by space-based instruments to look for chemical "fingerprints" of an exoplanet's atmosphere. Students will interpret transit light curves and graphs of Flux vs. Wavelength to apply their understanding. Don't miss the interactive model of the "Transit Method" and the interactive exoplanet catalog. Tutorials are provided for all levels of student understanding. This resource was designed to fit into a college-level introductory astronomy course, but it can easily be adapted to a high school physics curriculum as well. (See "NGSS" tab.)
