CUSHING — Peter Kalajian, a retired high school physics and astronomy teacher, will lead a naked-eye tour of the heavens Friday, Oct. 21, at Good Neighbor Park in Cushing. 

The night sky changes with each season and Kalajian will highlight the differences between autumn and spring, following his 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,” said the Library, in a news release.
