Part 5/11:
A close-up view of Enceladus reveals a moon characterized by a relatively smooth surface with few craters, indicating ongoing geological activity. This activity is driven by subsurface water reservoirs, possibly a global ocean beneath the icy crust near the south pole, under immense pressure. The cryovolcanoes (ice volcanoes) spray an estimated 200 kilograms of water per second into space at velocities exceeding 1,600 km/h, replenishing the E Ring and suggesting active water cycles similar to volcanic processes on terrestrial planets.
