Cryovolcanism’s Song of Ice and Fire

Erik Klemetti, Science Writer by Erik Klemetti 25 September 202316 October 2023

Ocean moons of the outer solar system hint at ice volcanoes, hydrothermal vents, and the tantalizing chance of habitability.

Illustration of a water-covered planet viewed from its surface: In the foreground is rippling water reflecting pink, yellow, and white light from a glowing phenomenon in the distance, in the middle of the illustration. Surrounding the bright phenomenon are bright stars and translucent clouds visible in front of a dark background.
