Cassini reanalysis finds polar heat on Enceladus, strengthening case for a long‑lived subsurface ocean
A reanalysis of Cassini thermal data shows Saturn’s moon Enceladus is leaking heat from both poles — not just the south — and used temperature measurements to estimate ice‑shell thickness. The balanced heat flow supports a long‑lived subsurface ocean and raises the moon’s potential as an abode for life.
