David Mittelman, Dennis di Cicco, and Sean Walker set out on an epic journey to image the hydrogen-alpha signal across the entire night sky. Not only are their images breathtaking, but their data have been used in a number of scientific publications. With 3,129 fields complete, they still have a ways to go, but their ambitious project continues to amaze! Sean Walker will tell us about the project.

Vale a pena ver e rever
