Astronomy Day at Grand Teton, held on Sunday, August 11th, marked the finalé of several weeks of ‘galactic’ activities. An estimated 700 visitors participated in daylong events beginning with astronomy videos in the Colter Bay Visitor Center auditorium and a special showing of the award winning documentary "The City Dark—a search for night on a planet that never sleeps."
During Sunday afternoon, specially filtered solar telescopes were available on the visitor center deck to offer people a close up view of our nearest star with its sunspots and other solar features. Activities concluded during the evening with an amphitheater program titled, "Watchers of the Sky."
Written and presented by Robert Hoyle, park ranger and former professional astronomer, “Watchers of the Sky” is a cultural history of astronomy and how early sky-watching evolved into the sciences of astronomy and astrophysics.
Hoyle’s presentation was followed by night sky observations through several telescopes provided and hosted by members of the local Jackson Hole Astronomy Club. Participants were able to view stars, galaxies, nebulae and other celestial objects across the expansive night sky of northwestern Wyoming.
This summer marked the 39th season of astronomy and sky interpretation programs at Grand Teton National Park. A highlight of the annual Astronomy Day events occurred May 20, 2012, when over a hundred people joined Grand Teton staff and members of the Jackson Hole Astronomy Club to watch an annual solar eclipse over the Teton Range.
