Two New Studies Boost Case for Detecting Life on Saturn's Moon Enceladus
A new analysis of nearly 1,000 Cassini measurements found Enceladus ice grains split into at least five chemical subtypes, improving searches for biosignatures.
- On Friday, Science Advances published two studies suggesting Saturn's moon Enceladus could harbor life, as new analysis of ice plumes reveals the moon naturally prepares samples for easier detection.
- Saturn's moon Enceladus features a hidden global ocean with plumes ejecting ice particles into space, providing the only extraterrestrial 'body of water' from which scientists can directly analyze samples.
- Led by Frank Postberg, researchers found 'Enceladus actually does a lot of the work for us' by separating and concentrating oceanic constituents into ice grains that accelerate to 1,000 km/h.
- Nozair Khawaja stated 'this was really a surprise to us,' as studies indicate geochemical conditions on Enceladus could support ancient metabolic systems even in highly alkaline environments with pH values of 10 or 11.
- Future spacecraft could identify biosignatures by analyzing individual ice particles, which Postberg described as 'that is great news in the search for life' using currently available technology.

Alien Life Can Survive on This Tiny Moon—We Just Need to Go Find It
Scientists have discovered that Earth-like microbes could potentially survive conditions inside Enceladus’s subsurface ocean, and that detecting signs of life on the moon may be easier than expected, according to a pair of studies.
A study by scientists from Germany and the United States showed that Earth's bacteria Methanothermoccus okinawensis are able to survive and reproduce under conditions that simulate Saturn Encelad's satellite. According to a publication in Science Advances, an ice satellite found signs of a alkaline soda ocean where hydrogen is formed during hydrothermal reactions and transmits RIA News. During the experiment, the carbon and energy exchange of ba…
Two recent studies suggest that microbes exist in the ocean of the ice moon Enceladus and may be more easily detected than previously thought.
The Eismond Enceladus is one of the most promising places for extraterrestrial life. A German research team mimics the conditions in the laboratory and marvels at the growth of a deep-sea individual.

fu-berlin.deGreat news from Saturn’s moon Enceladus in the search for life in space
Planetary scientists from Freie Universität Berlin have published two new studies in Science Advances with promising discoveries about the potential for life on one of Saturn’s icy moons. New evidence indicates that Enceladus might be more supportive of life than once assumed. In fact, spacecrafts already in planning could be used to identify evidence of life there much easier than previously thought, should it exist.
