Learning Video Game Development

At Play in the Cosmos - The Videogame (W. W. Norton & Company with GEAR Learning, 2017)

At Play in the Cosmos is a first-of-its-kind resource in astronomy education. Authors Jeff Bary (Colgate University) and Adam Frank (University of Rochester) worked with the nonprofit Learning Games Network to develop a mission-based online videogame where students can fly up to twenty missions that span the entire scope of introductory astronomy from basic physics to cosmology.

At Play in the Cosmos received the Games for Change and Mashable People's Choice Award in 2017.

Infrared and optical spectroscopy of young sun-like stars
