International Observe the Moon Night is a worldwide public event that encourages observation, appreciation, and understanding of our Moon and its connection to space science, exploration, and human culture. This annual event connects scientists, educators, and lunar enthusiasts around the world.

Door Prizes

Visitors will receive an informational handout with a Moon map and descriptions of objects of interest. Door prizes of NASA’s First Woman Augmented Reality Graphic Novel will be awarded. First Woman tells the tale of Callie Rodriguez, the first woman to explore the Moon. While Callie is a fictional character, the first female astronaut and person of color will soon set foot on the Moon. In-person demonstrations and videos will educate and entertain. Tours of the facility will be provided by observatory members including our 24-inch and 20-inch telescopes and associated domes and equipment. Weather permitting, visitors will have the opportunity to tour the Moon, planets and other celestial objects using our large telescopes.

Upcoming in the Observatory Lecture Series.

We encourage you to come to the observatory to meet our speakers either in-person or virtually on our high-resolution, conference screen and join in our always lively Q&A after presentations. Later, if the weather cooperates, we offer tours and viewing opportunities. Click on the image for more info. You can view past lectures in our video library.
