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.

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

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 ...

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

Observations of nearby red dwarf stars reveal rare carbon and oxygen isotopes, offering direct evidence of stellar nucleosynthesis and the chemical evolution of the Milky Way.
