The Cleveland Astronomical Society was established in 1922 and has a long   history of providing free  lectures to interested individuals. The lecture programs are presented by educators, engineers, and researchers on  topics related to astronomy and aerospace. Unlike a number of astronomical  organizations which concentrate on using their telescopes for night sky viewing,  C.A.S. focuses on indoor scholarly forums of expert presentations. The C.A.S. Outreach program makes a concerted effort to encourage astronomy  teaching and learning by inviting area high school science teachers and their  students to various lectures. There they will be exposed to astronomical  research work that employs the practical investigation to the scientific research  process. The Outreach program also allows teachers to network with other  teachers, students to socialize with other students and for all to be exposed to  a lecture event outside the regular classroom experience. C.A.S is also a co-sponsor of the Cleveland Museum of Natural History's  Frontiers of Astronomy Lecture series.  This is also a free and open to the public  lecture series which is held at the museum in the Murch Auditorium.  On clear  evenings, the Museum's Ralph Mueller Observatory is open afterwards.   The Cleveland Astronomical Society Upcoming Activities Meeting time and place November 3, 2016 Dr. Arthur B.
