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

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 may still be geologically active, judging from the way the lunar far side is wrinkling as the moon contracts. At least, that's what planetary scientists who have discovered 266 lunar ...

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

Quick facts about the moon. How far away it is: An average of 238,855 miles (384,400 kilometers) from our planet How big it is: 2,159 miles (3,475 km) across, or about one-fourth our planet's size ...

We think the moon formed after a colossal collision between Earth and another huge object created two balls of molten magma. But we don’t know exactly when or how. Now, scientists have made new ...

The moon's far side is pockmarked by craters and has fewer of the near side's flat, dark plains carved by lava flows. Why the two halves are so different remains a mystery, said study co-author ...

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 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.

Having completed developing the synthetic moon rocks, the research center had a new project ready for Team 116: measuring NASA’s airless flexible tires’ contact footprint, or the portion of the tires ...

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.

The authors compared the abundance of 70 elements in Moon rocks with their presence in Earth’s mantle and crust. They found a lack of elements that turn more easily to gas than lithium. This ...
