Briefings

New research suggests Earth formed with much of its water from reactions between rocky pebbles and a hydrogen-rich atmosphere during the planet's early stages. This process could explain how life's essential ingredient was acquired and may indicate similar mechanisms exist on other rocky worlds.

Key points

• Earth formed with water from reactions between rocky pebbles and a hydrogen-rich atmosphere during the planet's formation.
• The findings suggest similar water-producing processes could be common on rocky planets beyond our solar system.

Context

Research published in Nature Geoscience proposes that Earth acquired essential water during its formation, potentially enabling life. This mechanism may be widespread across the solar system.

Limitations

Evidence is limited to a single study from Nature Geoscience. The specific timeframe of pebble reactions and the exact duration of the hydrogen-rich atmosphere are not specified in the source.
