On October 28, 2017, celebrate our Moon in your community through International Observe the Moon Night (InOMN)


InOMN is an annual worldwide celebration of lunar and planetary science. Tens of thousands of people participate each year, from 98 countries and 49 U.S. states (and counting!).

You and your library are invited to join this world-wide celebration by hosting an InOMN event on one day each year to look at and learn about our Moon together. This year’s celebration is on October 28th.

InOMN encourages observation, appreciation, and understanding of our Moon and its connection to NASA planetary science and exploration. Everyone on Earth is invited to join the celebration by hosting or attending an InOMN event — and uniting on one day each year to look at and learn about the Moon together.

This Year’s Theme
In 2017, we are focusing on eclipses, in honor of the total solar eclipse that crossed the United States in August, a lunar eclipse that will occur in January, and past and future eclipses visible around the world. Eclipses are both beautiful to behold, and scientifically interesting. Here are some eclipse-focused activities recommended by the Lunar Reconnaissance Orbiter team that you may want to feature in your event.

InOMN is sponsored by NASA’s Lunar Reconnaissance Orbiter, NASA’s Solar System Exploration Research Virtual Institute (SSERVI), and the Lunar and Planetary Institute.
