Scientists have known about ice in the dark, deep craters at the moon's poles, some of the coldest known places in the universe, but voyaging into one just wouldn't be likely.

The Moon Has More Water and Ice Hidden All Over Its Surface Than Originally Predicted

Scientists discovered that water is stored in tiny patches all across the moon's surface, not just in the deep, freezing craters of its south pole

Halloween features a full moon every 19 years, and it's always a blue moon.

Nations must sign and uphold the agreement if they plan to join NASA's mission to send astronauts back to the moon

The projected path for 2020 SO, a space object that astronomers predict will become Earth's mini-moon in October, possibly staying until May 2021. The blue object in the center of the circle is Earth.

Earth May Soon Get Another Mini-Moon, but It's Probably Just a Piece of Space Trash

It could be an asteroid—or, as one astronomer suggests, it could be a rocket booster from the 1960s

On Earth, most people are familiar with ultraviolet radiation’s harmful effects on our skin, but in space, astronauts are also subjected to galactic cosmic rays, accelerated solar particles, neutrons and gamma rays.

Moonwalking Humans Get Blasted With 200 Times the Radiation Experienced on Earth

The new findings will inform how much shielding future astronauts will need to safely explore the moon

The blue areas in this composite image from the Moon Mineralogy Mapper (M3) aboard the Indian Space Research Organization's Chandrayaan-1 orbiter show water concentrated at the Moon's poles. Homing in on the spectra of rocks there, researchers found signs of hematite, a form of rust.

Why Is the Moon Covered in Rust? Even Scientists Are Stumped by This Metal Mystery

Without oxygen and water, how is the substance

Here, scientists at the Goddard Geophysical and Astronomical Observatory use the visible, green wavelength of light to shoot lasers at the Lunar Reconnaissance Orbiter. The laser facility at the Université Côte d’Azur in Grasse, France, developed a new technique that uses infrared light, which is invisible to the human eye, to beam laser light to the Moon.

Scientists Shot Lasers at a Lunar Orbiter for a Decade. Then, One Bounced Back

The success might help scientists troubleshoot problems with a data-collection project that dates back to the Apollo era

Goodnight Exomoon takes the classic children’s book Goodnight Moon and explores planetary science in a way that is relatable for the very young.

Inspire Your Toddler’s STEM Career With This ‘Goodnight Moon’ Parody

Astronomer Kimberly Arcand releases her new children’s book ‘Goodnight Exomoon’

To understand the ozone's composition, scientists analyzed sunlight that filtered through the Earth's atmosphere and reflected off the moon.

Scientists Use Moon as Mirror in Hunt for Extraterrestrial Life

The Hubble Telescope captured reflections of ultraviolet light to test for ozone layers

NASA has allotted $35,000 to be split among the three winning designs.

NASA Needs Your Help Designing a 'Lunar Loo'

Entries need to balance size, weight, functionality in microgravity and lunar gravity—and, of course, user experience

A near-infrared, color image taken by NASA's Cassini spacecraft shows the sun glinting off of north polar seas on Saturn's largest moon, Titan. Similar glints were spotted from Earth in 2000 at Titan's equator but Cassini found no evidence of liquid there.
