International Observe the Moon Night

International Observe the Moon Night (InOMN) is a worldwide, public 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, and to celebrate the cultural and personal connections we all have with Earth’s nearest neighbor.

A Global Celestial Celebration

Each year, thousands of people participate in InOMN at museums, planetaria, schools, universities, observatories, parks, businesses, and backyards around the world. Anyone, anywhere can host an International Observe the Moon Night event: events range from small family gatherings to community events drawing hundreds of visitors. InOMN events do not need to follow a set agenda: hosts can tailor their events to match their available resources and expertise, and the needs and interests of their communities.

InOMN and the 2017 Solar Eclipse

The moon is the central player in the total solar eclipse in August – and the highlight of International Observe the Moon Night.

After watching the new moon cross in front of the sun during the solar eclipse, catch it in another part of its orbit, and see how the sun’s light illuminates a spectacular lunar landscape, on October 28, 2017 – the next International Observe the Moon Night.

InOMN is an annual event, so you can continue to observe and learn about the moon and its connection to planetary science – and each of us – year after year.
