While orbiting #Saturn, the #Cassini probe spotted magnetic flow tubes empty of #plasma being transported toward the gas giant. Similar observations were recently made by the #Juno probe in the #Jupiter system.
Theoretical models suggest that this influx of plasma-empty magnetic flux tubes balances out an outgoing flow: in this case, the particle flows resulting from the intense volcanic activity of the moons #Io (Jupiter) and #Enceladus (Saturn) : https://www.irap.omp.eu/en/2025/10/what-goes-round-comes-around-inward-propagating-plasma-parcels-spotted-at-jupiter/

For nearly 13 years, the #Cassini probe orbited #saturn, its instruments measuring the energy and particle fluxes between the gas giant and its moons—particularly between Saturn and #Enceladus.
Analysis of the collected data revealed the existence of wave activity characteristic of #Alfvén #waves which occur when Saturn's magnetic field passes close to Enceladus. This is a first, demonstrating the long-distance influence of moons on their host planet.

A small, icy #moon of #Saturn called #Enceladus is one of the prime targets in the search for #life elsewhere in the solar system.
In 2005, #Cassini mission discovered geyser-like plumes of #water vapor and ice grains erupting continuously out of cracks in Enceladus' icy shell.
Organic compounds have been detected with confidence in plume material, including amines, which can be precursors to amino acids.
Much larger macromolecules have also been seen but their exact identity is currently uncertain owing to the limitations of the Cassini instrumentation.

Der Saturnmond #Enceladus scheint ein langfristig stabiles thermisches Gleichgewicht zu besitzen, das durch die starke #Gravitation des Saturn angetrieben wird, eine Art #Gezeitenheizung.
Neben einem ganzen Cocktail aus organischen Verbindungen, der in seinem Ozean nachgewiesen wurde, nährt dies die Hoffnung auf außerirdisches Leben in unserem #Sonnensystem.

Titan's Land of Lakes

http://www.nasa.gov/Explanation:
Saturn's large moon Titan would be unique in our solar system, the only world with stable liquid lakes and seas on its surface ... except for planet Earth of course. Centered on the north pole, this colorized map shows Titan's bodies of methane and ethane in blue and black, still liquid at frigid surface temperatures of -180 degrees C (-292 degrees F). The map is based on data from the Cassini spacecraft's radar, taken during flybys between 2004 and 2013. Roughly heart-shaped, the lake above and right of the pole is Ligeia Mare, the second largest known body of liquid on Titan and larger than Lake Superior on Earth. Just below the north pole is Punga Mare. The sprawling sea below and right of Punga is the (hopefully sleeping) Kraken Mare, Titan's largest known sea. Above and left of the pole, the moon's surface is dotted with smalle

Cassini narrow-angle camera image looking across the south pole of Saturn's icy moon Enceladus on 30 November 2010, 1.4 years after southern autumnal equinox.
Material sprays from cracks in the moon's icy surface known as 'tiger stripes'. The shadow of the body of Enceladus on the lower portions of the jets is clearly seen.

Enceladus is a highly active world, with a global, salty sub-surface #ocean, believed to be the source of its heat.
The presence of liquid #water, heat and the right chemicals (such as phosphorus and complex hydrocarbons) means that its sub-surface ocean could be one of the best places in our solar system for #life to have evolved outside the Earth.
A new study has provided the first evidence of significant heat flow at #Enceladus’ north pole, overturning previous assumptions that heat loss was confined to its active south pole.
This finding confirms that the icy moon is emitting far more heat than would be expected if it were simply a passive body, strengthening the case that it could support life.
The balance between heat production and loss strongly suggests that Enceladus’ ocean can remain liquid over geological timescales, offering a stable environment where life could potentially emerge.

#astrobiology news: New findings from #NASA’s #Cassini mission show that #Enceladus, one of #Saturn’s moons and a top contender for extra-terrestrial life, is losing heat from both poles – indicating that it has the long-term stability required for life to develop.

Evidence of significant heat flow at #Enceladus's north pole, overturning previous assumptions…
…infrared observations from the Cassini Composite InfraRed Spectrometer (CIRS)…found that the surface at the north pole was around 7 K warmer than predicted. This discrepancy could only be explained by heat leaking out from the ocean below…
…strengthening the case that it could support life.

Meanwhile in #Enceladus:
' While the new findings do not show that there is life on Enceladus, Khawaja said they indicate there are complex chemical pathways at play that could lead to the formation of substances that could be biological relevant.
The results, he added, support plans by the European Space Agency (ESA) to investigate the moon for signs of life. "I think all the signals are green here for Enceladus," Khawaja said. '

While direct exposure to high #radiation dose is indeed not favourable for biological activity, ionizing radiation can, and in some cases is known to produce a number of biologically useful products.
One such mechanism is the production of biologically useful products via charged particle-induced #radiolysis.
By combining energy deposition calculations with the energy requirements of microbial cells, it is possible to define the radiolytic #habitable zone for #Mars, #Europa, and #Enceladus, capable of sustaining microbial #metabolism.
Calculations suggest that bacterial cell density could be highest in Enceladus, followed by Mars and Europa.

I'm glad we're having this conversation now. I believe Humanity could find a purpose beyond mere survival, and that is to bring Life to a mostly dead and empty Universe.
But how dead is that Universe, we'll have to go out there and find out before we starting building biospheres on worlds such as Enceladus.
It's time we had better goals in life than raping this planet for money.#Space #Panspermia #RareEarthHypothesis #Enceladus #LateStageCapitalism
