The TriState Astronomers will hold a free public star party at Antietam National Battlefield Oct. 16 and 17 from sunset to 11 p.m.
Telescopes will be set up both nights near the visitor's center parking lot.
Participants will be able to view Jupiter and four of its moons, just like Galileo did 400 years ago. You'll be able to view the sky through a variety of telescopes throughout the evening. Bring your own telescope or binoculars if you wish. Laser guided tours of the stars and constellations found in the autumn night sky will also be held. This is an ongoing event for the whole family.
The event will be canceled if cloudy.
The battlefield is off Sharpsburg Pike, seven miles south of Hagerstown.
