The 25rd annual Grand Canyon Star Party will be held this June on both the South and North rims of Grand Canyon National Park. Amateur astronomers from across the country will volunteer their expertise. Free slide programs will be offered and numerous telescopes will be set up to view planets, star clusters, nebulae, galaxies, the moon, and the sun. National parks such as Grand Canyon are protective harbors for some of the last remaining dark skies in this country. Weather permitting; you can expect spectacular views of the universe!

This event is sponsored by the National Park Service, Tucson Amateur Astronomy Association (South Rim), and Saguaro Astronomy Club of Phoenix (North Rim), with funding from the Grand Canyon Association.
