Scientists think six icy moons 🧊 in our solar system may currently host oceans of liquid water 🌊 beneath their outer surfaces. Arranged around #Earth 🌎 are images from NASA spacecraft 🛰️ of, clockwise from the top, Saturn's moon #Enceladus, Jupiter's moons #Callisto and #Ganymede, Neptune's moon #Triton, Saturn's moon #Titan, and Jupiter's moon #Europa, the target of NASA's @europaclipper mission. The worlds here are shown to scale.

The images of the Saturnian moons were taken by NASA's @cassinisaturn. The images of the Jovian moons were taken by NASA's Galileo mission. The image of Triton was taken by @nasavoyager 2. The image of Earth was stitched together using months of satellite-based observations, mostly using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.
