EVENTS

Join us as we celebrate International Observe the Moon Night 2025!

In cooperation with NASA, Custer Observatory will be participating in this special International Observe the Moon Night event. This is a worldwide celebration of lunar science and exploration held annually since 2010. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor.

International Observe the Moon Night is sponsored by NASA’s Lunar Reconnaissance Orbiter mission and the Solar System Exploration Division at NASA’s Goddard Space Flight Center, and other NASA and astronomical organizations that encourage observation, appreciation, and understanding of our Moon and its connection to planetary science and exploration.

This is a weather-permitting event. If the weather is clear, observatory staff will be providing guided tours of the moon and other night sky objects through the many telescopes on site, including the apochromatic Zerochromat telescope in our historic observation dome.

$5 Adult, $3 Children Under 16 , Observatory Members FREE. Your donations allow Custer Observatory to continue to offer programs like this to the community and are greatly appreciated. Donations can be made at the door. Pre-registration is free and will help us guide our preparations for the event. Guests can arrive at any time between the hours of 7pm and 11:30pm.
