Astrotourism is Looking Up
Exploring the night sky in Southern Arizona
By Suzanne Wright
A night owl and a bit of an insomniac, I’m often outside late at night, looking up to the heavens. Lucky for me, the Grand Canyon State is one place you can see twinkling stars under the absolute best conditions. The clear, dry, dark skies devoid of light pollution above southern Arizona make for ideal stargazing.
I’m not the only fan.
According to a 2007 study, astrotourism contributes more than $250 million annually to Tucson’s economy. Dozens of public and private observatories, along with amateur astronomy clubs and even a couple of Tucson’s posh resorts, make learning about our cosmos easy.
Connecting to the cosmos
My first experience going to a “Star Party” was through a Meetup group. Twenty of us traveled from Phoenix to the base of Mt. Lemmon to join half a dozen hobbyists—some local astronomy teachers—who had set up 10 telescopes in a parking lot. It had been a cloudy day, but as twilight deepened to night, the skies cleared and our ranks swelled until about 40 people were gathered.
The telescopes were aimed toward the moon, Jupiter, Venus, Mars and various constellations. One of our hosts spoke of taking a “walk around the sky” as we peered through each. Another host shared folk stories from Native American and Celtic traditions and another answered questions.
With anticipation, I looked into the lens of the telescope aimed at the moon, astonished to see the surface craters so clearly! It looked so luminous, so big and so close.
We took turns, rotating through each telescope. Person after person had the same reaction—gasping and elated, the adults were as excited as the kids. Most of us simply uttered the word: “Wow.”
When not looking through the telescope, I peered up at the sky, thrilled to see an occasional shooting star. Time both slowed and sped that night. I was hooked.
A prime destination for stargazing
Southern Arizona has a dizzying array of stargazing programs. I wasn’t sure where to start—I wanted to attend every one!
I reached out to Scott Kardel, managing director of the Tucson-based International Dark-Sky Association (IDA), to help me sort out a stargazing strategy. IDA is a non-profit that champions dark skies and certifies parks and communities around the globe that meet specified criteria. Arizona’s commitment to dark skies has attracted world-class observatories.
“The SkyCenter at Mt. Lemmon and Kitt Peak are more structured, immersive experiences,” he explained. “Mt. Lemmon has one of the biggest telescopes—32 inches—anywhere.”
“In diameter?” I asked.
“Yeah, it’s impressive,” he replied. “You’ll be rubbing shoulders with research scientists at both places.”
My Aunt Millie lives in Oro Valley; she’s been to the SkyCenter at Mt. Lemmon and loved it. She even used the Mt. Lemmon app to take a science tour as she drove there. The app gave an informative audio tour through part of her drive to Mt. Lemmon, making her journey about discovery and learning rather than just getting to point B.
“The app’s audio followed right along with me as I drove,” she told me shortly after her trip.” It even inspired her to take a closer look at how the world works, telling me “I noticed that as I climbed there were fewer and fewer saguaros. Then the app told me it’s because saguaros can’t survive in cooler climates. I never noticed that there are so many layers of habitat to see here—there’s more biodiversity in the sky islands region than anywhere else in the U.S.”.
By the time my aunt got to the SkyCenter, she realized she had seen a new facet of Mt. Lemmon and was inspired. She actually became one of the most inquisitive visitors the SkyCenter has ever seen.
“After learning so much about the land around me, I wanted to know even more. I was excited to explore the sky as much as I had on the way up, so I unleashed every question that popped into my head,” she told me enthusiastically.
Her experience on Mt. Lemmon exponentially increased my curiosity about the world above. My aunt hadn’t been to Kitt Peak yet, so we happily agreed to further my exploration of the sky there.
Mt. Lemmon was named one of the 7 best bike rides in the world by 1843.
Awestruck at elevation
Located at an elevation of 6,880 feet, Kitt Peak sits on the Tohono O’odham Reservation approximately 50 miles southwest of Tucson. Scattered on the mountaintop are 27 telescopes from eight of the foremost astronomical research institutions in the world, including Harvard and MIT. It’s the largest collection of optical telescopes in the world. Conducting public outreach for half a century, Kitt Peak has been written up in such national publications as the New York Times, The Washington Post, the San Francisco Chronicle andDiscover Magazine.
Before departing for Kitt Peak, I received a call from the observatory personnel, confirming the weather was good. Mother Nature can preempt the best-laid plans with windy, icy or rainy conditions that can cause cancellation. We left by mid-afternoon for the Advanced Nightly Observing Program, an in-depth monthly event scheduled over five or six days around the new moon. The program is offered year-round and reservations are required; visitation is limited to 48.
The drive itself built anticipation as we left the desert floor, ascending Observatory Highway. The environment dramatically changed from stark saguaro and ocotillo to high-country piñon pine and oak. We rolled down the windows and breathed in the sweet aroma. There were several scenic pull-offs for picture taking or just soaking in the 360-degree vistas. Resident wildlife includes bobcats, roadrunners, deer, hawks, coyotes and coatimundis.
We were glad we brought fleece jackets; the temperatures were cooler even during summer months. After checking in, we watched a video, checked out the exhibits in the visitor center and browsed the gift shop. We were handed a boxed dinner (sandwich, chips, apple, cookies) to keep our tummies from grumbling during the four hours.
Our guides explained that we would spend the rest of the evening using three of the public telescopes—the best amateur equipment available—to explore the night sky. We could expect to see planets, star clusters and galaxies, maybe even a meteor shower.
But first we walked to a western-facing cliff to watch the sun set a fiery orange and fuchsia over the surrounding mountains. There were predictable “oohs” and “ahhs”—Arizona sunsets are the stuff of legends. Then we crossed to an east-facing cliff as night fell and learned about the physics of these atmospheric changes.
After breaking into three groups, it was sufficiently dark enough to make our way to the telescopes. Our group included visitors from South Korea, Germany, the Midwest, New York and locals. The luxuriant sky was celestial black velvet.
Inside the domes, we were seated in comfy chairs for a briefing. Then, one by one, we approached the telescope to view the night sky. The reactions were reverential: this is our Universe, up close and personal, glittering and bewitching. This must have been what my aunt was feeling at Mt. Lemmon: in front of my eyes, a whole new, excitingly beautiful world was being opened up to me.
“It’s magical, isn’t it?” said Aunt Millie.
I nodded. I’m glad I’m nocturnal. There’s so much to see in the Sonoran Desert even after the sun goes down.
From casual stargazing groups to advanced programs, Southern Arizona offers a fantastic variety of ways to look at the stars and appreciate our slice of the sky.
