There may be more water on the moon than previously believed, and it could be used as a resource during upcoming missions -- like NASA's return of humans to the lunar surface through the Artemis ...

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

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 ...
