Europa's leading hemisphere chaos regions have a spectral feature at 450 nm that has been attributed to absorption by crystal defects in irradiated sodium chloride, known as F-centers.

Are Water Plumes Spraying From Europa?

In 2005, images of a brilliant watery plume erupting from the surface of Saturn's moon Enceladus captivated the world.

Water vapor geysers on Europa have been inferred from observations made by the Galileo spacecraft, the Hubble Space Telescope, and the Keck Observatory.

Europa has been spotted to have water outgassing activities by the space and ground-based telescopes as well as reanalysis of the Galileo data (Roth et al. 2014; Sparks et al. 2016, 2017; Paganini et al. 2020; Jia et al. 2018; Arnold et al. 2019).

NASA's Hubble Space Telescope observations of Jupiter's icy moon Europa have revealed the presence of persistent water vapor - but, mysteriously, only in one hemisphere.

The Galileo Near Infrared Mapping Spectrometer (NIMS) collected spectra of Europa in the 0.7-5.2 μm wavelength region, which have been critical to improving our understanding of the surface composition of this moon.

Europa Clipper Hardware Makes Headway

Take a closer look at the complex choreography involved in building NASA's Europa Clipper as the mission to explore Jupiter's moon Europa approaches its 2024 launch date.

One of the clearest but unresolved questions for Europa is the thickness of its icy shell. Europa's surface is resplendent with geological features that bear on this question, and ultimately on its interior, geological history, and astrobiological potential.

Jupiter's moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.

Jupiter's icy moon Europa may be the most promising place in the solar system to find present-day environments suitable for life beyond Earth.
