What happens on the day we visit
We set up
We arrive 30 minutes early with the dome and a 360° hi-def projector. Nothing for your staff to move, borrow, or prepare.
We run the show
A live presenter guides every session on the same software major planetariums use — pitched to each grade, not a canned video.
You spark wonder
Students walk out excited about astronomy. We pack out in about 30 minutes and your gym goes back to being a gym.
Live lessons for every grade
Every lesson is live, interactive, and tailored to each group’s grade level.
- 20+ NGSS-aligned lessons, Pre-K through 12th grade
- A different presentation for each grade, if you want one
- Award-winning full-dome films, including Sesame Workshop’s One World, One Sky
- Pick your topics — or let us choose by age. Either way, no homework for you
An indoor space and a standard outlet
- Ideal: 25×25 ft with 13 ft of clearance — a regulation hoop and full backboard means you’re fine
- Tight on space? 20×20 ft with 12-ft ceilings works — and our low-profile dome handles ceilings down to 10 ft
- One standard outlet within 50 feet
- Staff to help line up and supervise students (they’ll enjoy the presentation too!)
- Students sit on the floor inside the dome, with a 360° view of the presentation
- Accessible to students with disabilities, including wheelchair users
Setup takes about 30 minutes. Teardown takes about 30 minutes. We’re packed out before dismissal.

Frequently Asked Questions
How many students fit in the dome?
For most grades, about 50 students fit at a time, along with our presenter and a few teachers. For junior high groups, plan on slightly fewer than 50; for high school seniors, about 40.
How many students can you get through in a day?
Up to 600 students in a day: twelve 30-minute sessions with as many as 50 students each. Actual capacity depends on grade level and how neatly classes divide into groups. High school groups usually run 40–45 students per session, or roughly 500 per day. Schools near the daily limit often benefit from a second day and a more relaxed schedule.
How much space do you need?
Ideally 25×25 ft with 13 feet of vertical clearance — a gym, multipurpose room, or large library meeting room. A regulation 10-foot hoop with a full backboard means you’re fine. Tighter rooms work down to 20×20 ft with 12-foot ceilings, and our low-profile dome handles ceilings as low as 10 feet — ask before you rule a room out.
Who’s coming to our school?
A trained, background-checked Galaxy on the Go presenter — experienced educators and performers who know how to hold a room of second graders and a room of high school seniors.
Is the dome accessible for students with disabilities?
Yes. Students can remain in wheelchairs, and we adjust entry and exit procedures to accommodate your students. It is helpful, but not necessary, to let us know ahead of time which of your groups may require these accommodations.
Is it really this easy? Any surprises?
No surprises. Our founder is a PTA parent who built this to be friction-free for schools. We arrive early, set up, run the sessions, pack out, and leave your gym exactly as we found it.
