A similar STEM immersion sequence was offered September 14-15 to 23 AAA teachers who attended a curriculum teaching workshop, learned about current infrared astronomy research from NASA Jet Propulsion Laboratory scientists, and received guided visits to the Keck Observatory’s remote observing facility on the Caltech campus and the Mt. Wilson Observatory, including a half-night’s reserved use of the historic Mt. Wilson 60-inch telescope. The teachers were invited to submit a list of objects to be observed with the Mt. Wilson telescope and viewed a wonderful array of star clusters, colorful double stars, and galaxies, with a grand finale view of Saturn and its rings.
