The history and development of astrology will be examined at Fiske Planetarium on March 10 and 11.
Lecturer Matthew Tearle and graduate student David Beltran-del-Rio, both of CU-Boulder's applied mathematics department, will present the "Science of the Signs" at 7:30 p.m. on both days.
During the show, which is intended for a general audience, they will examine the relationship between astrology and astronomy. They also will discuss equinoxes and solstices, and issues regarding setting calendars and timekeeping from the sky.
Admission for "Science of the Signs" is $6 for adults, $5 for students and $3.50 for children and seniors. Sommers-Bausch Observatory, adjacent to the planetarium, is open to the public following Friday shows, weather permitting. Admission to the observatory as well as guided viewing through the 16- and 18-inch telescopes is free.
