At about 3:15 a.m. on May 2, 2026, the 27.5-inch PlaneWave telescope at the International Dark Sky Discovery Center recorded an asteroid passing in front of a star. The center calls it the largest telescope in Greater Phoenix. It did that work from a building that still had drywall going up, HVAC to install, and no set opening day.
That order of events tells you where Fountain Hills stands this fall. The telescope came first. The planetarium, theater, and exhibit hall will follow, and the center's own target is now "sometime in February." The sky over the McDowell Mountains doesn't wait for a ribbon cutting, though. From now through early December, a local guide and a volunteer conservancy are running guided night-sky programs on the town's trails, mostly free or cheap. Some of them are only offered this season.
The Telescope Went First
The center's own updates show the observatory has been working ahead of the rest of the project. In May the organization laid out its plan for the months before opening. The observatory and private stargazing terrace would host public star parties, universities like ASU could rent telescope time, and the gift shop would open on select days, most likely Saturdays, until it can run full time.
The first public look most people got was this past weekend. During Fountain Hills Oktoberfest on October 2 and 3, festival ticket holders got early access to telescope stargazing on the Jackie Miles Private Viewing Terrace, and the gift shop stayed open from 5 to 10 p.m. both nights. Festival admission was $10 for adults and free for kids 12 and under. That was the Oktoberfest ticket. The center hasn't published a regular admission price.
I didn't find a dated public terrace star party on the center's pages for the rest of 2026. If you want to look through that telescope before February, the center's project updates are the place to watch.
What Still Stands Between the Building and Opening Day
The schedule has moved more than once. In October 2025, KJZZ reported the center expected to open around the middle of 2026. By May 2026 the center was aiming to finish construction by December 31, then spend one to two months furnishing. In July, CEO Dr. Cain Jagodzinski told ABC15 he expected construction to wrap at the end of December, with January for fine-tuning and an opening in early 2027.
The latest word is from the center's September 24 update:
McCarthy Builders are working fast and hard doing their best to meet our goal of opening sometime in February.
That same update lists where the work stands and what's still open:
- Framing and drywall. Almost all walls are framed, and drywall is up in many areas.
- Planetarium. A false floor is finished so crews can put up the scaffolding for the frame and the inner projection dome.
- Mechanical systems. HVAC and final electrical work are next.
- Public art. The certificate of occupancy depends on meeting the town's public art requirement. The center has commissioned Fountain Hills resident Brian Schader, the artist behind the Fountain of Light on Avenue of the Fountains, to build a Galileo sculpture with a globe, a telescope, and a backlit book. As of September, it was still looking for a sponsor to fund the $35,000 piece.
- Furnishings. In May the center said inflation had added more than $1 million to Phase 2 costs. It warned that some major pieces, including the Inspiration Theater, couldn't be fully furnished without more donations. The September update says the Grand Opening campaign is still raising money but doesn't say whether that gap has closed.
The center's homepage now says "Opening Early 2027." A Fountain Hills tourism page still shows an earlier January 2027 estimate. The center's September update is the newer source.
This Fall, the Program Runs on the Trails
While the building gets finished, the guided night-sky calendar in Fountain Hills has moved outdoors. Most of it runs through one person. Vicky Derksen hosts the Night Sky Tourist podcast and website, owns a local stargazing business, and volunteers as a steward with the Sonoran Conservancy of Fountain Hills. She is named as leader of four of the five programs below, and the fifth is a Night Sky Tourist hike.
There are two ways to sign up, and the difference matters. The conservancy's fall programs are free, have limited spots, and require pre-registration through the Town of Fountain Hills. Fall registration opened August 3. The Night Sky Tourist hikes are ticketed. Exact meeting spots go to ticket holders, and each hike has its own date when tickets go on sale.
| Date | Program | Where | Cost and sign-up |
|---|---|---|---|
| Sun., Oct. 18, 7 p.m. | Summer Triangle Twilight & Starlight Walk | Sent to registrants | Registration required. Price not listed |
| Mon., Nov. 9, 5:15–6:15 p.m. | Dessert in the Desert: Sunset, Twilight and a bit of Starlight | Adero Canyon Trailhead, 14800 N Eagle Ridge Dr. | Free. SCFH course 4225, through the Town |
| Mon., Nov. 30, 5:15–6:45 p.m. | Circumpolar Constellations Twilight and Starlight Hike | Sent to ticket holders | $15. Tickets open Nov. 2 |
| Mon., Dec. 7, 6:30–8 p.m. | The Moonless Desert Sky | Promenade Trail in the Preserve | Free. Register through SCFH, ages 8 and up |
| Wed., Dec. 9, 5:15–6:45 p.m. | Greek Mythology Twilight and Starlight Hike | Sent to ticket holders | $15. Tickets open Nov. 11 |
The October 18 walk is about a mile through the desert, with stories about the constellations and the Milky Way.
The November 9 program at Adero Canyon is the easiest of the five. It's a sit-down evening, not a hike. The conservancy tells people to bring a chair, family, friends, and a dessert or snack. It walks through the three stages of twilight as the desert changes from its day shift to its night shift, then ends with a laser-guided constellation tour and a look at deep-space objects through a telescope. Janice Holden co-leads. All ages are welcome, everyone has to register, and pets and alcohol aren't allowed.
The November 30 hike is also about a mile and covers Diné, Sámi, and Greek stories about the constellations that circle the pole.
On December 7, Derksen brings a telescope to the Promenade Trail for a program about the moonless sky. Children must be pre-registered and at least 8 years old.
Why the Trail Version Is Worth Doing First
Fountain Hills was building its reputation for dark skies long before the Discovery Center broke ground. DarkSky International's profile of the town says it strengthened its outdoor lighting ordinance in 2016 and was named an International Dark Sky Community in 2018. The same profile notes that the McDowell Mountains block some of the Phoenix area's light, so some Fountain Hills neighborhoods get skies dark enough to occasionally see the Milky Way.
Those are the conditions the fall walks use. You learn to find the Summer Triangle, the circumpolar stars, and the twilight stages without any equipment, from trailheads a few minutes from home. Once you know the sky that way, it carries over to the patio, the drive home on Shea, or a guest asking what that bright cluster is.
The building will add things the trail can't. The center lists five main parts: the Dark Sky Observatory, the Craig and Ruth Gimbel Planetarium with a tilted dome, the Inspiration Theater, the Night Sky Exhibit Hall, and the Einstein Exploration Station. The center says the theater will have 150 tiered seats and an LED video screen. ABC15 reported that screen will be 27.5 feet wide and 15 feet high, and that the exhibit hall will hold more than 60 exhibits.
One exhibit ties back to the trail programs. Inside a half dome, the Celestial Navigation exhibit uses a six-minute interactive video to show how Polynesian voyagers crossed the Pacific by the stars, sailing from Tahiti to Hawaii with no compass. The center calls it unique in the world. Split Rock Studios in Minneapolis, Winikur Productions in Boston, the Polynesian Voyaging Society in Honolulu, and Elumenati Design in Milwaukee worked together to build it. Someone who spent November 30 hearing Diné and Sámi star stories in the desert will walk into that exhibit already knowing how people read the sky.
Planning Around the Gap
A few practical details for this season:
- Mark the ticket dates. Tickets for the Night Sky Tourist hikes open on November 2 for the November 30 hike and November 11 for the December 9 hike, and the listings call space limited.
- Register for the free programs early. The conservancy's programs fill from a limited count, and you sign up through the Town's recreation catalog by course number.
- Don't count on hours or prices yet. The center hasn't posted regular admission prices or daily hours. ABC15 reported plans for weekend and evening access, weather permitting, plus daytime telescope and dome demonstrations.
- Follow the center's updates for terrace nights. Its May plan promised public star parties and Saturday gift shop hours before the grand opening, and Oktoberfest was the first one announced with dates.
That makes five dates, two of them free through the conservancy. Crews are still getting the planetarium ready for its dome scaffolding, and the next program on the calendar is the walk on October 18 at 7 p.m.
If you're new to Fountain Hills or helping someone get to know the area, I'm happy to share which of these evenings work best for first-timers and families. I like pointing people to the places that make this town feel like home, and the dark sky is one of them. Reach out to Kerri DeWaters anytime to start a conversation.
