Our nearest celestial neighbor revolves around Earth every 27 days at a distance of roughly 240,000 miles. Formed billions of years ago alongside our planet, the moon has played a major role in world religion and culture, and it is the only celestial body humanity has visited—so far. Discover the fascinating facts about the moon in our collection of the internet's best resources.
Hours of research by our editors, distilled into minutes of clarity.
Photos taken at the Cerro Tololo Inter-American Observatory in Chile in March 2025 captured a blood moon and the Milky Way galaxy within the same field of view. The moon appears red from the bluer parts of its reflected sunlight being scattered by Earth's atmosphere.
On March 2, 2025, Firefly Aerospace landed its Blue Ghost craft on the Moon. The private company then operated the craft for two weeks, conducting surface operations and becoming the first private space company to have a fully successful mission on the Moon. This short video captures pristine, dramatic footage of the mission's successful touchdown.
Anyone who has visited large bodies of water virtually anywhere on Earth notices low and high tides occur at regular intervals, a process primarily driven by the moon’s gravitational pull. This explainer details how the motion of the Earth and Moon interact to create tides.
Twelve astronauts have walked on the moon to date, and they all agree that our lunar neighbor smells like gunpowder. Scientists argue this scent comes from unstable minerals that cling to their suits and the rocks they return to the ship. Notwithstanding, space itself has a different smell, often compared to steak or metal, which experts believe, rather poetically, is the smell of dead stars.
The moon’s influence on our planet has mystified humans throughout history. A common reaction to the moon's perplexing power has been the belief that it can influence people's minds and even drive them mad. For example, the term "lunatic" originates from the Latin word for moon, luna. From ancient Greek and Roman texts to Michael Jackson's "Thriller," uncover the enduring mentions of lunar abilities and find emerging research on the topic in this Literary Hub article.
That familiar orb in our night sky must have come from somewhere. The most widely accepted theory about the Moon's origin is the giant-impact theory, suggesting the Moon formed as a result of a massive collision between early Earth and another small planet named Theia. Analysis of samples brought back from the Apollo missions revealed chemical similarities between the Earth and Moon, supporting this theory. The Moon's formation stabilized Earth's orbit and reduced polar motion, contributing to our planet's relatively stable climate. In this piece, planetary scientists weigh in on the best theories explaining the origins of the moon.
From modulating our tides to impact our climate, Earth's lone natural satellite plays a key role forming the planet's habitat. Before diving into the rest of the resources on this page, check out NASA's overview of the basics of the Moon—how it got its name, its size and distance from Earth, its structure, and much more.
Twelve Central Illinois residents are asked to share their thoughts on where they were when the first people landed on the Moon. This almost one-hour program is a collaboration of Eastern Illinois University's Booth Library, the EIU Department of History, and WEIU, and it premiered at EIU's Booth Library, January 24, 2019.
The Space Launch System is intended to be the most powerful rocket ever built by NASA. Possible missions include returning to the moon and perhaps even reaching Mars. This speculative and mostly silent video uses animation to explore the inner workings of the SLS, showing it launching and in space flight.
NASA's Artemis mission plans to see humans return to the moon by 2025, with long-term plans to build the first lunar base on its surface. To begin, astronauts will dwell for days at a time in SpaceX's Starship, which is capable of landing and taking off again from the moon. Over time, NASA plans to harvest minerals from the lunar surface to construct an oxygen pipeline as well as the rest of the base. Watch this video to see a sophisticated, detailed description of NASA's plans for the base.
From roughly 60 miles above the Earth's surface to farther than light has traveled during the entire age of the universe, space has captured human imagination for millennia. Explore the final frontier with the best resources curated from across the internet.
