Kind: research · Impact: low

## In brief

- Scientists report that rocky pebbles reacting with hydrogen under extreme heat can produce water in minutes.
- The proposed process could generate hundreds of oceans' worth of water in Earth's early fiery atmosphere.
- The idea challenges the long-held view that Earth's water was delivered by icy comets or asteroids.

## Why it matters

It offers an alternative explanation for the origin of Earth's water, which bears on how habitable planets form and where water comes from in planetary systems.
