Join observers from around the world on Saturday, Oct. 4, for NASA\u2019s International Observe the Moon Night. This annual event offers an opportunity for earthlings to celebrate the inspiring bond between Earth and the Moon, and, this year, to share in the excitement of NASA\u2019s preparations for Artemis II. Launching in early 2026, the mission will send four astronauts on a nearly 10-day flight past the Moon and back.<\/p>\n

On Saturday, the Moon will be in a waxing gibbous phase, with most of its face lit up by the Sun. Given these lighting conditions, viewers will be able to see many interesting sites with the unaided eye, binoculars, or telescopes \u2014 depending on local weather. Moon observers will see large, dark patches on the Moon called \u201cmaria,\u201d or \u201cseas\u201d in Latin. Thought to be seas of water for much of recorded human history, maria are large, flat plains of solidified ancient lava. This lava erupted from now-inactive volcanoes possibly for billions of years, starting about 4.4 billion years ago when the Moon formed.<\/p>\n

Depending on the type of viewing equipment used, some observers will be able to see geologic features such as craters, volcanic domes, and bright swirls on the surface thought to have formed in areas of local magnetic fields. This interactive map<\/a>, designed specifically for the Moon\u2019s phase on Oct. 4, highlights areas of interest and offers tips for viewing.<\/p>\n

From backyard viewing, to lunar art projects, to touching your way around the Moon\u2019s surface through 3D prints, there are many ways to participate in International Observe the Moon Night<\/a>, which drew an estimated 1.3 million participants from 127 countries in 2024.<\/p>\n
