Earlier research held that meteorite impacts from the solar system's early days were a major source of Earth's water.

For the Moon itself, the story is different. The Moon has far less water than Earth, but for such a dry world it’s important.

A new NASA study of its Apollo lunar soils clarifies the Moon’s record of meteorite impacts and timing of water delivery.

NASA's recent study, using lunar soil samples from Apollo missions, challenges popular theories about meteorites being the primary source of Earth's water.

A new NASA study using Apollo lunar soil samples challenges a long-held theory. It suggests meteorites were not the primary ...

NASA scientists are turning to the Moon to solve one of Earth’s oldest mysteries: where our water came from. A new study led by the US space agency uses Moon soil collected during the ...

Much of what scientists know about the early solar system comes from meteorites – ancient rocks that travel through space and survive a fiery plunge through Earth’s atmosphere. Among meteorites, one ...

Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The discovery not only ...
