We encourage you to interpret ‘observe’ broadly. From backyard viewing to lunar art projects to feeling the Moon through 3D prints, there are many ways to observe, enjoy, and learn about the Moon. Visit our website to find creative observing suggestions, a curated set of hands-on activities, display banners, and to download custom Moon Maps designed especially for this year’s event.
Register your participation, find tips and resources to host and evaluate events, sign up for our newsletter, and much more on the International Observe the Moon Night website: moon.nasa.gov/observe.
