Ancient Moon dust, meteorite traces and Apollo samples are helping NASA scientists rethink where Earth’s water truly came ...

A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth's history could have delivered a major share of Earth's water. A new study by Universities Space Research ...

A close-up view of a portion of a "relatively fresh" crater, looking southeast, as photographed during the third Apollo 15 lunar surface ...

Building on this discovery, Chinese scientists have developed a new lunar crater chronology model. The model allows for precise age estimates of unsampled lunar regions using only crater density ...

It was long thought, up until recently, that asteroids and comets delivered Earth's oceans during the very early Solar System ...

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

Late in 2024, astronomers spotted a new near-Earth asteroid named 2024 YR4. By mid-2025, its improved orbit tracking raised an unusual possibility: the space rock could hit the Moon on Dec.
