Earth's radiation budget is a core process of the Earth-atmosphere system, closely linked to global climate and environmental ...

The object dubbed Earth's "second moon" is actually a quasi-satellite that's accompanied the planet since 1957 — not a true ...

In a discovery that could rewrite what we know about where water comes from and the building blocks of life in the solar system, researchers have found rare meteorite pieces inside dust brought back ...

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 ...

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

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

Astronomers recently detected a stray quasi-moon in our planet’s orbit, but it's hardly the first stowaway to hang out around Earth. Unlike the Earth's moon, quasi-moons are not gravitationally bound ...

"The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner solar system. Earth and Theia are likely to have been neighbors." When you purchase through ...
