A new study found that Earth microbes can survive in simulated conditions of the ocean beneath the ice on Enceladus, Saturn's icy moon. Scientists exposed microorganisms to the moon's expected temperature, pressure and chemistry, and they endured. Researchers say the findings strengthen the case that Enceladus could support life and make future missions to sample its plumes more compelling.

NOAA Fisheries is highlighting a collection of 2.5 million tiny specimens described as perfect little time capsules of ocean chemistry. The samples preserve records of past ocean conditions, helping scientists track changes in temperature, salinity and marine ecosystems over time. The agency frames the collection as a valuable resource for understanding long-term ocean change.

New research explains how Saturn's moon Enceladus transforms its subsurface ocean spray into chemically varied ice grains, shedding light on the processes behind the plumes first observed by the Cassini spacecraft. The findings help scientists understand the moon's ocean chemistry and its potential to host conditions suitable for life.

Researchers at the University of California, Riverside report that shifts in ocean chemistry played a key role in maintaining Earth's oxygen levels, allowing complex life to keep breathing over geological time. The study, covered by Phys.org, explains how chemical processes in the oceans helped regulate the planet's atmosphere across Earth's history.

New findings describe how ocean spray venting from Saturn's moon Enceladus gradually freezes and shatters in space. The icy particles released from vents on the moon's south pole, which come from a global subsurface ocean, are slowly transformed by the extreme cold of space, shedding light on how Enceladus builds its famous plume and feeds Saturn's E ring. Researchers say the process offers fresh insight into the moon's ocean chemistry.
