Are these planetariums open to the public and do they run regular shows?
Many college and university planetariums in Wyoming offer public shows, but schedules vary by semester and season; some nights are reserved for classes or special events. Check each venue’s website or call ahead for show times, ticketing, and any COVID-era or maintenance closures.
What does “Dome diameter (m)” mean and should I care?
“Dome diameter (m)” is the dome’s width in meters and gives a quick sense of seating capacity and visual immersion: larger domes generally offer a more expansive projection surface, while smaller domes are fine for intimate educational programs—use it alongside location and address to choose the best fit for your visit.
