Saturn moon Enceladus’ ice shell likely thinner than expected
A vast ocean of water beneath the icy crust of Saturn’s moon Enceladus may be more accessible than previously thought, according to new research. A new study has revealed that near the moon’s poles, the ice covering Enceladus could be just two kilometers (one mile) thick—the thinnest known ice shell of any ocean-covered moon. The discovery not only changes scientists’ understanding of Enceladus’ structure, but also makes the moon a more appealing target for future exploration, according to the study’s authors.

‘Butterflies of the sea’ record ocean conditions in their shells
The shell of a tiny marine mollusk carries evidence of the ocean conditions that formed it, researchers have found. These “butterflies of the sea” could be used to determine the temperature and carbon dioxide levels of ancient oceans, they said this week at the American Geophysical Union’s Fall Meeting
