Kind: research · Impact: medium

## In brief

- Scientists report evidence of a primordial heavy water reservoir in the outer solar system.
- The findings are published in Science Advances, Volume 12, Issue 46, November 2026.
- ScienceAlert describes the water as hidden at the edge of the solar system and dating back about 4.5 billion years.

## Why it matters

The finding points to a preserved reservoir of primordial water in the outer solar system, which can inform how water was distributed during the solar system's formation.
