Due to its dark skies and clean air, Grand Canyon offers one of the best night sky observing sites in the United States. For eight days in June, (June 17 - June 24) park visitors explore the wonders of the night sky on Grand Canyon National Park's South Rim with the Tucson Amateur Astronomy Association and on the North Rim with the Saguaro Astronomy Club of Phoenix.
Amateur astronomers from across the country volunteer their expertise and offer free nightly astronomy programs and telescope viewing.
Through the telescopes you might view an assortment of planets, double stars, star clusters, nebulae and distant galaxies by night, and perhaps the Sun or Venus by day. At the 2017 Star Party, Jupiter and Saturn will be evening highlights, but you might find an astronomer pointing a telescope at Venus in the blue sky of morning. Skies will be starry and dark until the moon rises after 1 am.
