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 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 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 ...

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.

Moon rocks brought to Earth during NASA's Apollo missions in the 1960s and '70s, as well as data from orbiting spacecraft, have shown that parts of the lunar surface — particularly on the ...

In 2020, the Chang'e-5 spacecraft returned moon rocks from the near side, the first since those collected by NASA's Apollo astronauts and Soviet Union spacecraft in the 1970s.
