Saturn’s Moon Titan Could Have Formed in a Merger of Two Old Moons

by Keith CowingFebruary 11, 2026

Recent research suggests that Saturn’s bright rings and its largest moon, Titan, may have both originated in collisions among its moons.

Dragonfly Mission: Optomechanical Design Of The DragonCam Microscopic Camera

by Keith CowingJanuary 22, 2026January 22, 2026

The DragonCam Microscopic Camera is an instrument being developed for NASA’s Dragonfly mission [1] to Saturn’s moon Titan.

One set of images taken by Huygens is pictured here showing the view from 2 km altitude. It is in Mercator projection, so the N–S/E–W directions cross at right angles but surface areas appear distorted. Sky above horizon is modfied for formatting.- ESA/Astrobiology.com Original image

Cassini Study Found Organics From An Ocean Inside Enceladus

by Keith CowingNovember 19, 2025November 19, 2025

NASA’s Cassini spacecraft captured dramatic plumes, both large and small, spray water ice out from many locations along the famed ‘tiger stripes’ near the south pole of Saturn’s moon Enceladus.

Water-group Ion Irradiation Studies Of Enceladus Ice Analogues: Can Radiolysis Account For Material In And Around The South Polar Plume?

by Keith CowingOctober 27, 2025October 27, 2025

Saturn’s magnetosphere contains trapped plasma and energetic charged particles which constantly irradiate the surface of Enceladus.

The four giant planets as seen by Hubble WFC3/UVIS at different near-UV wavelengths, and processed by Judy Schmidt (note - these images are not shown to scale). The Jupiter and Saturn images are constructed from F343N (red), F275W (green), and F225 (blue), whereas a lack of observations for Uranus and Neptune required us to shift to redder wavelengths: F547M (red), F467M (green), and F336W (blue) for the Ice Giants. Jupiter and Ganymede were observed 2017-02-02 at 12:16UT, Saturn was observed at 2018-06-07 at 00:06UT, Uranus on 2015-08-30 at 10:08UT, and Neptune on 2015-09-02 at 07:58UT. Strong UV absorption is visible at the poles of Jupiter and Saturn due to the nature of highaltitude aerosols and the potential link to auroral chemistry. Red vortices, such as Jupiter’s Great Red Spot and Oval BA (lower left), appear dark due to the blue-absorbing chromophore responsible for their red colours. Uranus’ bright north polar cap of aerosols, and its narrow rings, are just visible in this image. Neptune’s banding, and some bright high clouds (appearing in pink) can be seen in both northern and southern hemispheres. In addition, Saturn’s rings appear reddish due to UV absorption.

Exploring Giant Planet Atmospheres with Habitable Worlds Observatory

by Keith CowingOctober 22, 2025October 22, 2025

Visible and ultraviolet imaging and spectroscopy of Solar System giant planets can set the paradigm for the atmospheric, ionospheric, and magnetospheric processes shaping the diversity of giant exoplanets, brown dwarfs, […]

The continuum-divided spectra of the Saturnian satellites, in the region of the O-D absorption. The red line shows a gaussian fit to the data using a fixed width. Most satellites have separate measurements for the leading and trailing hemispheres, but Hyperion and Phoebe, which are not synchronously rotating, only have single measurements. The O-D absorption is robustly detected at nearly every satellite. -- astro-ph.EP
