Talk topic:  The Astronomy of Stonehenge.

The massive stones of Stonehenge have been an enigma for millennia and attract tens of thousands of visitors each year. After centuries of archaeological investigation, we have learned who built them and when they were first erected.  In the 1960s astronomer Gerald Hawkins analyzed the layout of the stones with a computer and discovered that the stones point to spots on the horizon related to the motions of the Sun and Moon, and also suggested that they were used to predict eclipses.  Come see the stone alignments and find out what’s happening with the stones on Salisbury Plain.

Talk starts in the Mott-Van Winkle Center room (note change of location).  No prior knowledge of astronomy is required – just curiosity.  After the talk there will be stargazing if the weather permits.  Free; open to the public.  Children under 16 must be accompanied by an adult.  Dress warmly, as even in the summer it may be chilly.
