For eight days in June, park visitors to Grand Canyon National Park can explore the wonders of the night sky on Grand Canyon National Park’s South Rim with amateur astronomers from across the country who will volunteer their expertise an offer free nightly astronomy programs and free telescope viewing.   On the South Rim, events will include a slide show nightly at 8:00 p.m., followed by telescope viewing behind the Grand Canyon Visitor Center. Parking is available in lots 1 through 4, and the Village Route shuttle bus runs every half-hour until 11:00 p.m. To make sure you get a seat at the slide show, arrive a few minutes early. On the North Rim, telescopes will be set up on the porch of the lodge every evening, with some possibility of daytime scopes available as well. Bulletin boards at the Visitor Center will list additional events such as star talks and special slide show programs in the Grand Canyon Lodge auditorium. The event is free other than paying the park entrance fee of $25.00 per vehicle, good for 7 days of coming and going to either rim. No reservations are needed except for astronomers wishing to share their telescopes, who register through the astronomy clubs sponsoring the event. Come for a night, or for the whole 8 night-event. Explore the Grand Canyon by day, and the universe by night!
