What the evidence shows

Researchers identified phosphate salts in ice grains measured by Cassini. Laboratory experiments and geochemical models helped interpret those measurements.

Why it matters

Phosphorus is part of the chemistry used by terrestrial life. Finding it adds to the case for studying Enceladus as a possible habitat.

What remains unknown

The measurement does not demonstrate organisms or biological activity. How life might originate or persist in the ocean remains an open research question.
