Illustration of the thermal structure of Titan’s atmosphere and its atmospheric processes. It illustrates the high-altitude photochemistry of N2 and CH4, leading to the formation of more complex organic molecules, aerosols, and cloud systems. It also depicts surface–atmosphere interactions and highlights the methane cycle (evaporation, condensation, and precipitation). -- Nature via PubMed

Titan’s Organic World

by Keith CowingMay 24, 2026May 24, 2026

Titan, Saturn’s largest moon, possesses a dense N2–CH4 atmosphere driving complex organic chemistry. The interplay among photochemistry, aerosol formation, organic cloud condensation, and surface deposition makes Titan a natural laboratory […]

Titan is an abode of NH3. (A) Titan captured by the Cassini Imaging Science Subsystem. The thick atmosphere of Titan is visible by a haze across the surface and a lack of surface details. Saturn’s other moon, Tethys, is observed behind Titan. Image credits: NASA/JPL-Caltech/Space Science Institute. (B) False-colour mosaic of Titan obtained by the Visual and Infrared Mapping Spectrometer of Cassini. Colours correspond to atmospheric (red) and surface features (green and blue). The inset image indicates the possible occurrence of a cryovolcano on the surface. Cryovolcanic slurries of water, NH3, and methanol have been tentatively observed on the surface.

Ammonia As A Parameter Shaping Habitability On Icy Moons

by Keith CowingMay 6, 2026May 6, 2026

The search for life now extends beyond the traditional habitable zone to include the icy moons of Jupiter and Saturn. These moons feature ice-covered surfaces overlying substantial oceans formed primarily […]

Astrobiology Exploration: Dragonfly Rotorcraft Hardware Integration and Parachute Test

by Keith CowingApril 24, 2026April 24, 2026

NASA’s Dragonfly rotorcraft is beginning to take shape – literally – with the delivery of the panels that make up the rotorcraft lander’s body. Built from ultra‑lightweight honeycomb panels designed […]

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I. Fujii/L-INSIGHT [Kyoto University], Illustrator: Shinichiro Kinoshita

How Jupiter Cultivated More Large Moons Than Saturn

by Keith CowingApril 8, 2026April 8, 2026

The two largest planets in our Solar System, Jupiter and Saturn, also have the largest satellite systems, or the most moons. At present, Jupiter’s reported moon count stands at more […]

Subsurface Ocean Salinity And Dissipation Rate Inferred From Enceladus Ice Shell Morphology

by Keith CowingMarch 31, 2026March 31, 2026

The habitability of Enceladus’ subsurface ocean and the detectability of potential biosignatures depend on efficient ocean circulation and suitable ocean conditions.

Fully corrected and calibrated albedos of Titan (yellow), Saturn (green), Uranus (blue), and Neptune (red) covering 0.3 µm to 2.1 µm, offset for clarity. Regions of strong telluric absorption are masked in lighter shades, and it should be noted that they are less reliably corrected. The flat regions in the UV were flagged as bad pixels in all images by X-shooter. We also highlight a vertical discontinuity between the VIS and NIR arms of Titan, which is likely due to weather inconsistency. The colors used for these objects are the same in the following figures. -- Astronomy & Astrophysics

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.
