Moon lovers rejoice! International Observe the Moon Night returns on Sept. 19. Here's everything you need to know about how to participate in the annual celebration of Earth's natural satellite both in-person and from the comfort of your home.
International Observe the Moon Night takes place around the first quarter moon in September or October, when the moon is conveniently visible in the late afternoon and evening. It's also an excellent phase for exploring features along the terminator — the boundary between lunar day and night — where long shadows help craters, mountains and other features stand out according to NASA.
The global celebration aims to raise awareness of lunar observation, science and exploration, which has intensified in recent years as NASA and its partners work to return humans to the surface of the moon as part of its Artemis program.
