Be Prepared

The Astronomy Festival is one of the most exciting and busy events and weekends at Great Basin National Park. Planning ahead of time will ensure you have the best experience during your visit. Check back at this page regularly for updates if event schedules change.
Tips for a successful Astronomy Festival visit:

  • Campgrounds will fill up quickly. Arrive early to secure a first-come, first-served campsite within the park. Please visit the Lehman Caves Visitor Center or Great Basin Visitor Center for information on dispersed camping on public land outside of Great Basin National Park.
  • Fit into one car if possible. Parking is limited at astronomy events and you will be turned away if parking lots fill.
  • Bring red lights. White flashlights are not allowed at festival events in order to preserve everybody's night vision.
  • Bring plenty of layers. Telescope viewing can go well into the evening and nights get cold. Check weather forecasts as the festival approaches.
  • All events are free, but reservations may be required. Check the list below or the park's events calendar for information on specific events and if reservations are required.
  • Interested in volunteering? Our festival star parties are almost entirely volunteer run and registration is required to volunteer. Find more information at this link or further below.

Event Descriptions

Find details of each event during the Astronomy Festival below. Check the schedule above for dates and times of each event.

Telescope Viewing & Star Parties

Each night, amateur astronomers gather their telescopes near the Astronomy Amphitheater to showcase the night sky and dazzle with a peek through their eyepieces. Look at colorful star-forming nebulas, ancient star clusters, far off galaxies millions of light years distant, or the planets which dot our night sky.

Telescope viewing is driven almost entirely by volunteers donating their time and the use of their delicate equipment to the park. Treat volunteers and their telescopes with the care & respect they deserve.

*UPDATE - Volunteer registration has closed for 2024*
Interested in being a volunteer at the astronomy festival? All that's required is a telescope and a passion to share with the general public. If you'd like to volunteer, please contact the Astronomy Rangers via email by clicking here. Pre-registration is required, and those who show up without registering ahead of time will be turned away. If registration is full, you may still contact us to be on the interest check for the following year.

Guest Speakers

Each year we invite speakers from the professional astrophysics and astronomy realms to come speak about their research, projects, or their work. During two nights of the festival, all are invited to the Astronomy Amphitheater to listen to their presentations, ask questions, and learn more about the endless possibilities of astronomy.

The festival's keynote speakers this year are Dr. Cameron Pace, a professor of Astronomy at Southern Utah University who leads research using the Great Basin Observatory inside the park, and Dr. Gregg Hallinan, a professor and researcher involved in the proposed DSA-2000 radio telescope near the park. Dr. Pace will present on Friday, and Dr. Hallinan on Saturday.

Additional Guest Speakers are featured through the day on Saturday. We are joined by NASA Solar System Ambassador Jessica Rzeszut and NASA/JPL Ambassador Jerry Hilburn. Jessica's talk will focus on the James Webb Space Telescope and its mission, while Jerry will share more on the Great Basin Observatory and how to become part of the scientific process in a national park.

Great Basin Observatory Tours

Advanced reservation for Great Basin Observatory Tours is highly encouraged. Reservations for two daily tours open at 8:00 am Pacific Time on August 5th. Register for GBO Tours at this link. After you sign up for a program you will receive instructions via e-mail. All park program participants must check in at the Lehman Caves Visitor Center the day of the program.

Art in the Dark

Join a Ranger and our Artist-in-Residence in an art project that experiments with how our eyes see color. This accessible and kid-friendly program will challenge artists to create and paint in low light conditions, under the guidance of the Astronomy Rangers. All needed art supplies will be provided.

Together, visitors and rangers will create a dazzling art piece in the Astronomy Amphitheater. This large piece will then be displayed for the remainder of the festival for all to see and share in.

Recommended equipment

  • Blankets
  • Warm clothing

Solar Telescopes and Crafts

Behind the Lehman Caves Visitor Center, rangers will have a solar telescope set up, allowing anybody to come and view our planet's closest star safely. View sunspots and prominences, filaments and ejections through our specialized telescope and see the sun as you never have before.

Next to the telescope, join in creating small, take-home crafts. Build a constellation using pipe cleaner and UV sensitive beads which change color under sunlight and glow in the dark. Perfect for all ages! No registration required, just drop by.

Note: If weather is poor, solar scope will be set up but the sun may not be visible.

Ranger Programs

Join park rangers as they present their astronomy programs in the dark of the Lehman Caves Visitor Center. Topics vary, but our dark sky rangers will guide you through the night sky, our relationships with the stars, and the protected dark of Great Basin.

Programs are free and require no advance registration, but the theater is limited in space. Some standing room is available.

Want to see some of these programs beyond the festival? Attend one of our many astronomy programs throughout the summer to see what our rangers have to share in addition to telescope viewing. Learn more here!

 

Accessibility

Have concerns about mobility or parking? What about bringing a service animal? Many questions about park programs and accessibility can be answered through our accessibility pages.

We strive to make every program just as easy to attend for every member of the public, regardless of ability. However, the nature of some telescopes make them impossible to view through without standing and balancing safely.

The best programs to attend for those with limited mobility will be:

  • All Ranger Programs and Guest Speakers
  • The Solar Crafts Table behind the Lehman Caves Visitor Center each day
  • Constellation Talks at the Astronomy Amphitheater each night
  • Art in the Dark the first night of the festival at the Astronomy Amphitheater

All may attend the Star Party each night and volunteers may have devices to allow those unable to stand or balance to view the telescope's focus. Great Basin Observatory tours are not fully accessible due to the stairs and gravel pathways leading to the dome.

Worried about making it to the Astronomy Amphitheater from the Lehman Caves Visitor Center parking lot? Speak with a ranger when you arrive and let them know. Limited parking is available for those with mobility issues next to the telescope viewing area and Astronomy Amphitheater.

Weather and Cancellations

September tends to be a predictably mild month, but rain & thunderstorms may occur. In the event of poor weather, events may be cancelled or moved and notice will be posted at the Lehman Caves Visitor Center throughout the weekend.

  • Indoor events will take place rain or shine
  • Outdoor events will be cancelled due to rain or thunderstorms
  • Keynote speakers will be shifted to Baker Hall with posted signage in case of rain or thunder. Ample seating is available.
  • Clouds alone will not cancel any events. Events will continue at their regularly scheduled times.
