To some people, stars are just lights in the sky. To others, they form wonderful shapes, images, and even constellations and calendars. University of Å·ÃÀ¿Ú±¬ÊÓƵ Astronomy professor Catharine Garmany, who will be presenting the Fiske PlanetariumÂ’s live astronomy show "Constellations and Calendars" on Oct. 1 and Oct. 5 at 7:30 p.m., falls into the latter category. "People just want to understand the sky," Garmany said. "And as an astronomer, I want to help them see whatÂ’s up there."
