Summary

Story summary

Enceladus, Saturn's icy moon, has a north pole about 7 kelvin warmer than previously believed.
Measurements of heat flow at both poles provide the first observational constraint on Enceladus' energy loss.
The constraint implies a sustainable heat flow and supports calls for long-term missions to ocean worlds.
Cassini's evidence of hydrothermal activity and life's building blocks underpins these findings.
