Every Tuesday, Friday, and Saturday evening (except where noted), the Visitors Center opens for our popular Twilight and Star Party programs.
The Twilight Program is a theater-based program led by our education staff. Depending on the time of year and the moon phase, two different versions of the program are offered. Tickets are required to participate. This program frequently sells out. Discounted passes are available via our online reservation system (see below) until three hours prior to the program. Please include all members of your party in your reservation to ensure appropriate seating. Approximate program length: 50-60 minutes. Scheduled 1.5 hours before the Star Party.
Participation in the Twilight Program is not required for enjoying the Star Party. The Twilight Program is not a prerequisite for participation in the Star Party.
Enjoy night sky constellation tours and views of celestial objects through a number of telescopes in the Rebecca Gale Telescope Park at the Frank N. Bash Visitors Center every Tuesday, Friday, and Saturday evening. Program is approximately 2 hours in length. Fun for the entire family. Dress warmly, the program takes place outdoors. In the event of rain, significant clouds, or high winds/dust/humidity, a series of indoor presentations will stimulate your interest and curiosity.
Depending on the season, we welcome 250-1,000 people to Star Parties. Guests receive a guided orientation in the open-air amphitheater and then rotate through various telescopes to view objects targeted by staff. Tickets are required. In order to provide a safe and enjoyable experience for all visitors and protect our sensitive environment, ticket capacity is limited and strictly enforced. Star Parties on Holiday weekends often sell out months in advance. Star Party program passes may be purchased online until they're sold out or up to three hours prior to the program start time. After that time, if any passes remain unsold, those may be purchased upon arrival.
During Daylight Saving Time, the Visitors Center is open 10 a.m.-5:30 p.m., re-opening before the Twilight Program begins. The Visitors Center is open from 10 a.m. through the end of the Star Party during Standard Time. Star Party start times change with the seasons. Check the calendar for program offerings and start times for the date you plan to visit. Be considerate with your headlights when leaving the Star Party and exit the parking lot to the west.
