Due to space restrictions and volunteer availability, we have limited opportunities.

Astronomy Night tickets are released in stages to give everyone a chance to join us:
• Most tickets unlock automatically 60 days before each event (to the exact time – tix for a 730 pm event will unlock at 730 pm 60 days earlier). Check the reservations page daily in the evenings for any new releases.

• We hold back a small number of tickets every month, which are then released on the 1st of the event month, usually between 6 am and 7 am.

Keep an eye out for Saturdays!
Saturdays are typically reserved for private group events, but if a date is still open by the 1st of the month (which is less common in spring and summer), we’ll add it as an extra Astronomy Night and release those tickets on the 1st.

Occasionally, an event may sell out early due to special bookings, so first- or second-release tickets could be limited or unavailable on that date. While rare, this can happen.

Finally, any last-minute cancellations that open up new ticket availability will be announced on our Facebook, Twitter, and Bluesky accounts.

You can always watch the reservations page for any last-minute openings. You will be able to see all dates coming up in the next 60 days. Astronomy Night dates will only be on Tuesdays, Thursdays, and Saturdays. Gray boxes are already sold out; green boxes indicate at least one available ticket.

At this time, we do not offer a waiting list. It is difficult to maintain with volunteers and would be hundreds of guests long.

We also host a FREE mini-star party at sundown on the south lawn of the University of Denver’s Historic Chamberlin Observatory every month. Weather permitting, look through the observatory’s 20-inch Alvan Clark-Saegmuller refractor telescope and meet fellow amateur stargazers with telescopes on the lawn out front. Ask the experts there about their equipment, or bring your own if you have questions about how it works and what to look at.

You can check our Events Calendar for the next Saturday Open House this month.

Anywhere far away from city lights is best. Earth and Sky maintains a list of crowdsourced locations recommended for sky viewing.
