Sunset on the Jets

As the long winter night deepens at Enceladus south pole, its jets are also progressively falling into darkness in this image observed by NASA Cassini spacecraft.

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.

#Enceladus’ subsurface ocean 🌊 has #hydrothermal vents on its seafloor.

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.

#Saturn’s ‘Death Star’ #moon has hidden #ocean under its crust, say scientists
#Mimas, the icy Saturnian moon famed for its resemblance to the Death Star, hides a liquid ocean under its crusty surface. The 250 mile-wide object joins#Titan and #Enceladus (and #Jupiter's #Europa and #Ganymede) in the secret subterranean sea club
Calculations suggest a 45-mile-deep internal body of#water lurks beneath Mimas’s 15-mile-thick icy shell https://www.theguardian.com/science/2024/feb/07/saturn-death-star-moon-mimas-hidden-ocean

A new astronomy cover for the Science Advances Journal, starring Enceladus, the icy moon of Saturn.

Feature article by Wanying Kang (MIT Earth, Atmospheric and Planetary Science Department) on the ocean stress on icy moon ice shells, and its impact on the habitability of these satellites.

Key compounds that could support alien microbes or help #life emerge have been detected in the enormous plume of water that erupts from vents in #Enceladus’ icy shells.

These compounds include hydrogen cyanide, which can be toxic to humans but is also a key building block for synthesizing more complex compounds including amino acids, sugars and nucleobases.

Enceladus might be seen as a favorable #prebiotic system.
