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

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 ...

For a long time, scientists assumed that Earth's water was delivered by asteroids and comets billions of years ago. This coincided with the Late Heavy Bombardment (ca. 4.1 to 3.8 billion years ago), a ...

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

A 12-pound chunk of the moon that fell to the Earth as a lunar meteorite has been sold at auction for more than $600,000. Boston-based RR Auction announced Friday the $612,500 winning bid for the ...

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

How did meteorite impacts on the Moon influence water being delivered to Earth when both planetary bodies were forming? This is what a recent study publish | Space ...

NASA research using Apollo lunar regolith data refines the Moon’s impact record and places limits on meteorite contributions to Earth’s water over geologic time.

High-precision oxygen isotopes in Apollo lunar soils reveal a persistent impactor fingerprint, showing that impacts contributed only a tiny fraction of Earth's water In a paper published in the ...
