Entry No. 55 — the Boise file — filed under: after-dark
Boise State University Astronomical Observatory
Run by the Boise State physics department's student outreach team (AstroTAC), this rooftop observatory atop the Science/Education Building aims a 16-inch Schmidt-Cassegrain telescope at the night sky. The marquee public night is First Friday Astronomy: a 7:30pm talk followed by a climb up to look through the dome (weather permitting). When the observatory is closed, the same crew sets up portable telescopes for free public stargazing on the campus Quad instead. It's an unfussy, locals-and-students scene where the volunteers will happily walk you through whatever is up that night.
The story
Most people walking along Cesar Chavez Lane on campus have no idea there is a 16-inch Schmidt-Cassegrain telescope sitting inside a white dome on the rooftop of the Education Building. Run by AstroTAC—a crew of Boise State physics students and student outreach volunteers—the observatory turns an unassuming academic roof into a window for double stars, planetary rings, and deep-space nebulae right in the middle of town. If you duck into the hallway leading toward the main stairwell, you'll walk past a custom mural depicting a black hole and its accretion disc, painted by AstroTAC team member Robin Matson to set the mood before you head up.
The crown jewel here is First Friday Astronomy, a monthly event where the physics department hosts guest researchers at 7:30 PM for a free public lecture before opening the rooftop hatch for viewing. When weather or building access locks down the dome, the crew doesn't pack up—they haul portable telescopes out to the central campus Quad between Albertsons Library and the Administration Building, turning the grass into an open-air observing site. It's an unfussy, volunteer-driven setup where you can ask a student to aim the optics at Saturn or a binary star without paying a dime.
What it's like
Expect a casual mix of students, families, and neighborhood regulars heading up the stairwell after dark or lining up on the Quad grass under campus streetlights. The key to not wasting a trip is checking the physics department's webpage at exactly 12:00 PM MT on Friday, which is when the student volunteers post the decision on whether the dome will open, if viewing moves to the Quad, or if weather has canceled the night entirely. Roof breezes off the Boise River can be chilly even in late spring, so bring an extra layer, and don't expect a slick commercial show—you'll be hanging out with passionate student volunteers who will gladly walk you through whatever is visible through the eyepiece that night.
The move: Reserve a Friday slot, climb to the rooftop dome after dark, and let a grad student center the telescope on a double star for the two of you.
📍 Before you go Reservations required and weather-dependent; status is posted each Friday at noon, and during some semesters viewing moves from the rooftop dome to the campus Quad.

Pair it with
- The Stein Luminary — Stay right on campus for an evening that moves from 90 feet of interactive digital projections and high-resolution art screens straight up to an optical telescope under the stars.
- Pengilly's Saloon — Head across the river into Old Boise after stargazing to talk astronomy over a drink beside a century-old Brunswick backbar.
- Seated Lincoln (Giant Borglum Statue) — Take a dusk walk through Julia Davis Park to sit next to Gutzon Borglum’s bronze Lincoln before crossing over to campus for night-sky viewing.
Good to know
How much does it cost to visit the observatory?
Visiting is completely free, though First Friday Astronomy lectures and public stargazing events accept optional donations to support the student outreach program.
When is the observatory open to the public?
Main events happen during First Friday Astronomy at 7:30 PM on the first Friday of every month, with additional Friday stargazing sessions running from after sunset until midnight when weather permits.
How do I check if stargazing is happening on a given Friday?
Check the Boise State physics department website every Friday at 12:00 PM MT, where student volunteers post the official weather and event status call for that evening.
What happens if the rooftop dome is closed?
If the rooftop dome is inaccessible due to maintenance or building schedules, student volunteers set up portable telescopes on the campus Quad between Albertsons Library and the Administration Building instead.
Where should I park when visiting?
The best nearby parking for the Education Building and rooftop observatory is the Brady Street Garage on campus, where visitors can pay at a kiosk or use a campus parking permit.
