The movie showcases the Chandra X-ray Observatory, one of NASA’s four great observatories and the world’s most powerful telescopes for detecting X-rays. The movie has been accepted for screening at the U.S. Air Force Academy ("USAFA" for short) Planetarium and will highlight how scientists use clusters of galaxies, the largest bound objects in the Universe, to learn more about the formation and evolution of the cosmos --- as well as the space telescopes used for this purpose, and the stories of the astronauts who launched them and the scientists who went before Dr. Hart in learning more about the nature of the Universe.
