After visiting #OceanWorlds in the outer solar system, #Mars, and #Venus, I got to bring everyone home to #Earth. Earth is very special because it's the only place, after decades of searching, where we know #life exists. We have life thanks to our #Oceans. #PlanetaryScience #Astrobiology 🪐🧪🔭

Beneath icy surfaces, six moons may hide vast oceans of liquid water! Shown to scale, these potential ocean worlds include Europa, Enceladus, Titan, Ganymede, Callisto, and Triton. Could they harbor life? #OceanWorlds #NASA #Astrobiology
An infographic showing six icy moons that may currently host subsurface oceans: Saturn's Enceladus and Titan, Jupiter's Europa, Ganymede, and Callisto, and Neptune's Triton, arranged around an image of Earth for scale. Images were captured by NASA's Cassini, Galileo, and Voyager 2 missions. Earth's image is a composite from the Terra satellite. These moons are key targets in the search for life beyond Earth.

14 Jan 2005: ESA’s Huygens probe landed on Titan 🪐 — still the only landing in the outer Solar System.

Titan remains a top “ocean world”–adjacent target: rich organics, active chemistry, and an incredible natural lab for thinking about prebiotic pathways.

A close-up image of Saturn's moon Enceladus, showcasing its distinctive "tiger stripes" in a false-color blue. These cracks in the icy surface spew plumes of ice particles into space, hinting at the possibility of a subsurface ocean and potentially extraterrestrial life. The image, captured by the Cassini spacecraft, highlights the moon's unique geological activity and its contribution to Saturn's E-ring.
