Europa, Ganymede, and Callisto are key targets in the search for habitability due to the potential presence of subsurface oceans. Detecting complex organic molecules (COMs), essential for prebiotic chemistry, is […]
In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called ‘soda pop geysers,’ are a new and reliable Earth-based analog for […]
A recent study by geophysicists at Washington State University offers insight into how nutrients may reach the subsurface ocean of Europa, one of Jupiter’s moons and a leading candidate for […]
Editor’s note: there are currently two advanced missions heading for the jovian system – Europa Clipper and ESA Juice – to study icy Europa and the other icy worlds orbiting […]
While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean […]
SwRI-led Ultraviolet Spectrograph viewed 3I/ATLAS both when and where most other assets could not.
From Europa to other icy moons, scientists are studying how surface features form and what they might reveal about the potential for life.
During November 2025, ESA’s Jupiter Icy Moons Explorer (Juice) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what […]
Ocean worlds such as Jupiter’s icy moon Europa and Saturn’s counterpart, Enceladus, could be among the most favorable places to discover life beyond Earth—and perhaps even a second, independent origin […]
In the outer solar system beyond Jupiter, water ice is a dominant component of planetary bodies, and most solid objects in this region are classified as icy bodies.
