Determining the Atmospheric Composition of Exoplanets

In this activity, use spectral patterns of exoplanets' atmospheres to acquire information about atmospheric composition, as well as what other variables scientists consider when looking for planets that might support life. This activity is appropriate for high school and university introductory physics and astronomy courses.This activity is just one of the many resources for educators and students included in the Exoplanet Atmosphere Digi Kit. A Digi Kit is a web-based interactive lab that blends physics, geometry, and astronomy as students build and use physical models to explore phenomena. Digi Kit resources include a core lesson plan, videos, simulations, tutorials, and readings.

The Exoplanet Atmosphere 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. Watch the pre-lecture video to learn more about implementing the activity.
