Recently in the Europa Category

Europa is a prime candidate for life in our solar system, and its deep saltwater ocean has captivated scientists for decades.

Europa is a premier target for advancing both planetary science and astrobiology, as well as for opening a new window into the burgeoning field of comparative oceanography.

Salt water within the icy shell of Jupiter's moon Europa could be transporting oxygen into an ice-covered ocean of liquid water where it could potentially help sustain alien life, according to a team of researchers led by The University of Texas at Austin.

We present maps of surface composition of Europa's anti-jovian hemisphere acquired using high spatial resolution IFU multi-spectral data from the SPHERE instrument on the Very Large Telescope (0.95 to 1.65μm) and the NIMS instrument on the Galileo orbiter (0.7 to 5.2μm).

Included in the payload of science instruments for NASA's Europa Clipper is the Plasma Instrument for Magnetic Sounding (PIMS). Scientists will use PIMS to study the characteristics of plasma around Europa to better understand the moon's ice shell thickness, ocean depth, and ocean salinity.

Europa's surface composition and evidence for cryovolcanic activity can provide insight into the properties and composition of the subsurface ocean, allowing the evaluation of its potential habitability.

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).
