The Story
A new NASA study published on January 25, 2026, casts doubt on the long-held belief that meteorites were a primary source of Earth’s water. The research suggests that meteorites only delivered a small amount of water to our planet over the past four billion years. This finding necessitates a re-evaluation of prevailing theories about the origin of Earth’s oceans and the planet’s early hydration.
Key Points
- The NASA study indicates that meteorites contributed only a small fraction of Earth’s water.
- The research spans the past four billion years.
- The study challenges the dominant theory of meteoritic delivery of water.
Key Takeaways
- Current scientific understanding of Earth’s water origin needs revision.
- Alternative sources of Earth’s water might have been more significant than previously thought.
- The early history of Earth’s atmospheric and geological processes demands further investigation.
