Kind: research · Impact: low

## In brief

- A new study suggests most of Earth's carbon originated in the outer solar system.
- The carbon reportedly arrived only during the late stages of planetary development.
- The claim is based on analysis of magma droplets called melt inclusions.

## Why it matters

The finding bears on how Earth acquired its carbon, a key element for life and planetary chemistry, and on the origin of volatile materials in the inner solar system.
