Star Parties and Twilight Programs

 

McDonald Observatory remains closed to the public

 

Evening programs routinely sell-out well in advance throughout the year: Reserve your tickets below.


Important: McDonald Observatory is located 450 miles west of Austin and is on Central Time.


Every Tuesday, Friday, and Saturday evening (except where noted), the Visitors Center opens for our popular Twilight and Star Party programs. Click here for these popular programs' start-times.

Twilight Program

The Twilight Program is a theater-based presentation led by education and outreach staff prior to the Star Party. Tickets are required to participate and this program frequently sells out.  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. 


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. Star Parties are approximately 2 hours in length. Fun for the entire family. Dress warmly, the program takes place outdoors. 

Depending on the season, as many as 600 people may participate in Star Parties. Tickets are required, and in order to provide a safe and enjoyable experience for visitors and protect our sensitive environment, program capacity is limited and strictly enforced. Star Parties on Holiday weekends often sell out weeks in advance. We strongly encourage purchasing Star Party program passes in advance as passes are rarely available the day of the program.

Star Party start times change with the seasons. Check the calendar for program offerings and start times for the date you plan to visit.



K-12 Teachers: Bring your class to the observatory for an educational and inspiring Student Field Experience.


Looking for a "big telescope", small group experience? Check out our Special Viewing Night programs available on several of our research telescopes!
