Earth's Moon: Formation, Composition and Orbit

The new moon of May 2024 will see the bright constellations of summer begin to rise just as those of winter sink below the horizon.

The full moon of April 2024, called the Pink Moon, will occur during the evening hours of April 23. Later that night, Mars and Saturn will rise in the predawn hours.

This month's new moon, which occurs on April 8, is a special one: It will cause a total solar eclipse, the last such event to grace the contiguous United States for two decades.

The moon reaches its first quarter moon phase on Dec. 19, crossing the sky in the Pisces constellation as the last half-moon of 2023.

November is when the winter constellations of the Northern Hemisphere become more prominent; it's the time of year when Orion, Taurus and Gemini are visible almost all night long.

A lunar eclipse visible to potentially millions of stargazers across the Eastern Hemisphere on Saturday offered an early skywatching treat before Halloween.

The final supermoon of the year, the Harvest Moon of September, gave skywatchers the final lunar thrill of the season.
