International Observe the Moon Night is on September 14

Join the global celebration

With the Moon reaching its first quarter on September 14, lunar enthusiasts and curious minds worldwide are gearing up for International Observe the Moon Night. This annual event, which takes place in September or October, invites people from all walks of life to celebrate lunar science, exploration, and personal connections to Earth’s celestial neighbour.

International Observe the Moon Night is a unique opportunity to explore the wonders of the Moon, whether through virtual or in-person events or simply from the comfort of your own home.

This year, the event falls on September 14, with subsequent observations set for October 4, 2025, and October 17, 2026.

Ideal phase

The first-quarter Moon, visible during this time, provides exceptional viewing conditions. The line between night and day, known as the terminator, accentuates the Moon’s cratered surface with striking shadows, making it an ideal phase for observing lunar features.

Participants are encouraged to embrace the theme broadly, engaging in activities ranging from celestial observations to sharing Moon-inspired artwork and stories. Whether hosting a local event, joining an online discussion, or simply observing from a vantage point, International Observe the Moon Night aims to unite people globally in a shared celebration of the Moon.

To connect with fellow lunar enthusiasts, join the conversation on social media using the hashtag #ObserveTheMoon.

The goals of International Observe the Moon Night are to:

• Unite people worldwide in the joy of lunar observation and science.
• Raise awareness about NASA’s lunar science and exploration programmes.
• Empower individuals to delve into Moon and space science through accessible resources.
• Facilitate the sharing of Moon-related stories, images, and artwork.
• Inspire ongoing interest in observing the Moon and the cosmos.

NASA’s Lunar Reconnaissance Orbiter mission and the Solar System Exploration Division at NASA’s Goddard Space Flight Centre sponsor International Observe the Moon Night, with support from various contributors.

Did you know?

Earth’s Moon is the only place beyond Earth where humans have set foot so far.

The brightest and most prominent object in our night sky, the Moon, makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.

According to NASA, the Moon was likely formed after a Mars-sized body collided with Earth several billion years ago.

Earth’s only natural satellite is called ‘the Moon’ because people did not know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. In Latin, the Moon was called Luna, the main adjective for all things Moon-related: lunar.

As you prepare to celebrate International Observe the Moon Night, the Moon awaits your gaze, whether outdoors, online, or from home.
