Visitors to Grand Canyon National Park will have an opportunity to see vivid views of countless stars, constellations and planets and learn about the night sky at the 32nd annual Star Party.
The Star Party is returning in person June 18-25, 2022, after having been online last year due to the pandemic. Activities sponsored by the Tucson Amateur Astronomy Association and the Saguaro Astronomy Club of Phoenix will take place at both the South and North rims.
Star Party activities are included with the park admission fee, which is $35 per vehicle, good for seven days.

The Star Party will take place on both rims over the course of eight days. Events include evening programming that begins at 8 p.m., constellation talks, telescope viewing with over 60 telescopes and photography workshops.
Telescope viewing at the South Rim begins at sunset behind the Visitor Center. The best viewing will be after 9 p.m. At the North Rim, telescopes will be set up on the porch of Grand Canyon Lodge every evening.
Dress warmly as temperatures drop quickly after sunset even during the summer. Telescopes will be taken down after 11 p.m.
More than 12,000 visitors are expected to participate during the eight days, according to Rader Lane, night sky park ranger at the Grand Canyon. Lane suggests that visitors bring red flashlights instead of white ones for a better after-dark experience.

The recipe to see stars doesn’t just require a telescope and a dark sky. The Grand Canyon was specifically designated as an International Dark Sky Park in 2019 by the International Dark-Sky Association.
This designation is awarded in one of two ways: One, if a location is able to retrofit a certain percentage of lights to be dark-sky friendly; and two, if it demonstrates a commitment to education and outreach about the night sky. In Arizona, Kartchner Caverns State Park and Petrified Forest National Park are among the locations that have achieved dark-sky status.
At Grand Canyon, Lane said, 34% of the 5,000 lights in 2016 met the criteria to be dark sky friendly. Since then, over 1,500 light fixtures have been retrofitted to eliminate light pollution.
The process involved shielding the lights, using lower-wattage bulbs, adding timers to some lights and getting rid of some lights altogether.
“I can’t really think of any other place that has so much infrastructure while also maintaining such pristine natural darkness, especially within the South Rim of the Grand Canyon,” Lane said.
“That is to say, there (are) places in the country that are supremely dark, but they’re incredibly remote and they’re hard to get to. And then there (are) some places that have a lot of hotels and infrastructure and places that people can access, but that usually is accompanied by light pollution.”
