For years, specialists have observed multiple flashes of light on the Moon. Initially, many believed them to be illusions, ...

The moon's thin atmosphere, called an exosphere, has been a puzzle to science for some time. Two main processes were thought ...

"geologically dead" Moon rocks reveal hidden lunar history As NASA astronauts aim for landings in 2027, geologists find surprises in recently retrieved samples from the far side ...

The moon is made mostly of rocks that are rich in iron and magnesium. The moon's face is covered in craters, which were left by various space objects that slammed into the moon over billions of years.

The new lunar missions should bring back a wider variety of rocks. The Apollo missions were limited to landing in equatorial regions to ensure communication with Earth, but more satellites mean the ...

The moon quickly began to cool. Most of the lunar magma ocean solidified almost right away by geologic standards—about a single millennium. But once about 80% of the magma had solidified, a crust of ...

Now, a study in the journal Nature argues for the earlier age, saying that the ancient Moon also went through a period when it got hot and partially remelted, producing new rocks about 4.35 ...

The collision caused both planets to temporarily splatter apart into globs of gas, magma, and chemical elements before reforming into the bodies we know today to be the Earth and Moon.

Where did the moon’s magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft picked up signs of a high magnetic field in lunar surface rocks. The ...

While the moon once had a weak magnetic field generated by a small molten core, the team's research suggests it likely wouldn't have been strong enough on its own to magnetize surface rocks.

The adjusted timeline from Nimmo’s team may also help explain why minerals on the moon called zircon — which were found in Apollo moon rocks — were estimated to be roughly 4.5 billion years old.
