Where Earth's Water Originally Comes From | Naked Science | Spark
Spark・2 minutes read
Earth's water origin remains a mystery, with researchers exploring comets, meteorites, and theories of water condensation in the early solar system to understand its source, with possible links to Jupiter's gravity and deep Earth water. Computer models suggest Earth-like planets could form with water, increasing the possibility of finding planets with liquid water and potential alien life.
Insights
- Analysis of Halley's Comet water reveals a crucial difference in the ratio of heavy to light hydrogen compared to Earth's water, indicating comets may not be the source of all Earth's water.
- Mathematician Morbidelli proposes a theory on how water from the asteroid belt reached Earth, suggesting Jupiter's gravity played a crucial role in mixing wet and dry materials, leading to Earth's water composition.
