CUSHING — Peter Kalajian, a retired high school physics and astronomy teacher, will lead a naked-eye tour of the heavens at Good Neighbor Park in Cushing on Friday, Oct. 21. The night sky changes with each season and Kalajian will highlight the differences between autumn and spring, following his popular presentation to an audience last April. He is also a photographer of stunning astronomical images. Gather time is 7:30 p.m. Bad weather alternative dates are October 23 and the following weekend. Needless to say, dress appropriately.
