CIERA Postdoctoral Fellow Aaron Geller won first place in the proposals division of the 2015 Northwestern Data Visualization Challenge, with his interactive visualization exploring stellar evolution. This work-in-progress will allow students and other astronomy enthusiasts to investigate the changes that occur in stars over cosmic time. When finished, the visualization will provide an interface to explore data from state-of-the art stellar evolution models, and will be used within inquiry-based classroom lesson plans.
