Thermal Inertia Controls on Titan’s Surface Temperature and Planetary Boundary Layer Structure
Understanding Titan’s planetary boundary layer (PBL) — the lowest region of the atmosphere influenced by surface conditions — remains challenging due to Titan’s thick atmosphere and limited observations.

The Detection-vs-Retrieval Challenge: Titan As An Exoplanet
Cassini’s observations of Titan’s atmosphere are exemplary benchmarks for exoplanet atmospheric studies owing to (1) their precision and (2) our independent knowledge of Titan.

Measurement of Photochemical Haze Refractive Indices and Hygroscopicity: Influence of CO2 in CH4/H2S/N2 Mixtures
Atmospheric organic hazes are widespread across various planetary bodies and have significant effects on both the surface and atmosphere. In this study, we investigate the optical and hygroscopic properties of […]

Titan In-situ Resource Utilization (ISRU) Sample Return (TISR)
Titan is unique in the outer solar system in that it is the only moon with a thick atmosphere, and the only body in the solar system outside the Earth […]

Cloud and Haze Parameterization in Atmospheric Retrievals: Insights from Titan’s Cassini Data and JWST Observations of Hot Jupiters
Context: Before JWST, telescope observations were not sensitive enough to constrain the nature of clouds in exo-atmospheres. Recent observations, however, have inferred cloud signatures as well as haze-enhanced scattering slopes […]

Titan’s Mysterious Wobbling Atmosphere Is Like A Gyroscope
The puzzling behaviour of Titan’s atmosphere has been revealed by researchers at the University of Bristol for the first time.
![Seasonal distribution of methane clouds in Titan’s troposphere. (a) Latitudinal distribution of clouds observed from Cassini and ground-based observatories [6, 54, 105], overlain on the zonal-mean precipitation distribution averaged over 40 Titan years of a simulation with TAM [57]. Vertical dotted lines indicate the timing of solstices (northern winter solstice and northern summer solstice, NWS and NSS) and equinoxes (northern vernal equinox and northern autumnal equinox, NVE and NAE); thin contours denote isolines of diurnally averaged top-ofatmosphere insolation, and grey shaded regions denote latitudes and times of polar night. (b) A simplified illustration of the expected atmospheric circulation during late northern summer leading to upwelling at northern mid-latitudes, which promotes cloud formation there, as observed by JWST and Keck most recently (see Figs. 4 and 5). -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/05/The-Atmosphere-of-Titan-in-Late.png?resize=1200%2C718&ssl=1)

The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations
Saturn’s moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan’s northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017), but the northern summer […]

Evidence Of Clouds Bubbling Up Over Titan’s Northern Hemisphere
Maunakea, Hawaiʻi – Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have, for the first time, found evidence for cloud convection in the northern hemisphere of Titan, Saturn’s […]
