International Observe the Moon Night

Written by Andrea Jones, NASA GSFC

International Observe the Moon Night (InOMN) is an annual worldwide celebration of lunar science and exploration. One day each year, everyone on Earth is invited to unite and observe and learn about the Moon and its connection to planetary science, and share personal and community connections we all have to the Moon.

InOMN 2015 is coming up on September 19, 2015.

We invite you to be a part of it, by hosting or participating in an InOMN event.

Check out the map of registered events on If no one is hosting an InOMN event near you, you can host your own! Invite your friends, family, neighbors, or your whole community to look at and learn about the Moon with you. Events can be any size, from large public events at science centers to backyard gatherings.

Hosting an InOMN Event
A guide that walks you through the process of planning an InOMN event of any size is available on the InOMN website, complete with advertising materials, suggested activities, an InOMN Moon map, evaluation materials, and more.

Worried about cloudy weather obscuring your view of the Moon?
The “Moon as Art” collection, chosen by the Lunar Reconnaissance Orbiter (LRO) team, showcases data and images from LRO – a spacecraft currently in orbit around the Moon – that reveals just how beautiful science can be! High-resolution images, with descriptions, are available here.

Additional beautiful, high-resolution images of the Moon’s surface taken by LRO’s cameras are available here.
