PORTLAND – Inspired by the total lunar eclipse that occurred on Dec. 20, the Southworth Planetarium at the University of Southern Maine presented a special program, “Mid Winter’s Eve at Stonehenge.”

USM physics professor Patrick Peoples usually presents this lecture about Stonehenge and other ancient neolithic structures on the midsummer’s eve.

The ancient rock structures in England are among the most famous in the world. Built more than 4,500 years ago, Stonehenge still keeps its mysteries, including who built it and for what purpose.

On New Year’s Eve, the planetarium will be open for various other shows from 7 p.m. to midnight. The shows are:

7 p.m. Extreme Planets

8 p.m. Eight Planets and Counting

9 p.m. Black Holes

10 p.m. Two Pieces of Glass

10:30 p.m. Winter Sky Tour

11 p.m. Images of the Infinite 2011
