Dark Moon, Dramatic Plume

Below a darkened Enceladus, a plume of water ice is backlit in this view of one of Saturn most dramatic moons. This image was captured by NASA Cassini spacecraft.

Enceladus the Powerhouse

This graphic, using data from NASA Cassini spacecraft, shows how the south polar terrain of Saturn moon Enceladus emits much more power than scientists had originally predicted.

Ring Backdrop

Saturn moon Enceladus brightly reflects sunlight before a backdrop of the planet rings and the rings shadows cast onto the planet. NASA Cassini spacecraft captured this snapshot during its flyby of the moon on Nov. 30, 2010.

Encroaching Shadow

This image from NASA Cassini spacecraft, one of those acquired in the survey conducted by the Cassini imaging science team of the geyser basin at the south pole of Enceladus, was taken as Cassini was looking across the moon south pole.

Craters Crowd the North

This view from NASA's Cassini spacecraft shows battered terrain around the north pole of Saturn's icy moon Enceladus. Craters crowd and overlap each other, each one recording an impact in the moon's distant past. The moon's north pole lies approximately at the top of this view from Cassini's wid...

I love the detail in the cover image, showing white #DNA strands and #molecules erupting from #Enceladus’ #cryovolcanoes ❄️🌋

It transforms a beautiful but vague snapshot into a highly precise, readable map of a cryovolcano in action!

Preventing Data "Washout"

If Cassini had taken an exposure long enough to make those faint outer plumes visible to a standard camera, the brightly lit crescent of Enceladus itself would have turned into a giant, blown-out blinding white smear, destroying all the data near the surface. False-color processing allows scientists to look at the brightest areas and the dimmest areas at the exact same time without losing details to glare or shadow

Fountains of Enceladus - Image #2

Recent Cassini images of Saturn's moon Enceladus backlit by the sun show the fountain-like sources of the fine spray of material that towers over the south polar region. The image was taken looking more or less broadside at the "tiger stripe" fractures observed in earlier Enceladus images. It s...

Brilliance Beyond the Rings

The Cassini spacecraft looks past the illuminated side of Saturn rings to the brilliant moon Enceladus.

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.

With Enceladus making the headlines for the detection, in data taken by the Cassini spacecraft Cosmic Dust Analyzer, of phosphates originating in its subsurface ocean, let's enjoy this 2015 Nature cover featuring some simulated eruptions from fractures in the moon's surface.
