TONIGHT is International Observe the Moon night, where astronomers across the world celebrate the astronomical body's importance to our planet.
NASA is encouraging everyone to take time out to observe the moon as it passes the first quarter phase and appears brightly iluminated in the night sky.
The event is designed to get people, young and old, to observe the moon and its surface, either through a telescope, online or, depending on yor location, with the naked eye.
Noah Petro, deputy project scientist for NASA's Lunar Reconnaissance Orbiter, told Space.com: "It's very exciting, especially if somebody doesn't do it normally."
NASA's official website says: "International Observe the Moon Night (InOMN) is an annual worldwide public event that encourages observation, appreciation, and understanding of our Moon and its connection to NASA planetary science and exploration, as well as the cultural and personal connections we all have with Earth's nearest neighbour.
