How Titan Maintains Its Atmosphere
Southwest Research Institute partnered with the Carnegie Institution for Science to perform laboratory experiments to better understand how Saturn’s moon Titan can maintain its unique nitrogen-rich atmosphere.

Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores
With the recent realization that there likely are stably-stratified regions in the interiors of both Jupiter and Saturn, we construct new non-adiabatic, inhomogeneous evolutionary models with the same microphysics for […]

Hubble Celebrates A Decade Of Tracking Outer Planets
Encountering Neptune in 1989, NASA’s Voyager mission completed humankind’s first close-up exploration of the four giant outer planets of our solar system. Collectively, since their launch in 1977, the twin […]

Titan Has An Insulating Methane-rich Crust Up To Six Miles Thick
Saturn’s largest moon Titan is the only place other than Earth known to have an atmosphere and liquids in the form of rivers, lakes and seas on its surface. Because […]

A Combined 3D Model Applied To Cloudy Warm Saturn Type Exoplanets Around M-dwarfs
Warm Saturn type exoplanets orbiting M-dwarfs are particularly suitable for in-depth cloud characterisation through transmission spectroscopy due to their favourable stellar to planetary radius contrast.

Sulfur in the Giant Planets, their Moons, and Extrasolar Gas Giant Planets
We review sulfur chemistry of the gas giant planets and their moons where sulfur compounds are observed. The major S-bearing gas in the upper atmospheres of the giant planets is […]

Classifications For Exoplanet and Exoplanetary Systems
When a star is described as a spectral class G2V, we know its approximate mass, temperature, age, and size. At more than 5,700 exoplanets discovered, it is a natural developmental […]

A Photochemical PHO Network For Hydrogen-dominated Exoplanet Atmospheres
Due to the detection of phosphine PH3 in the Solar System gas giants Jupiter and Saturn, PH3 has long been suggested to be detectable in exosolar substellar atmospheres too. However, […]

Twin Worlds, Divergent Fates: How Obliquity has Differently Shaped Pluto’s and Triton’s Landscapes and Climates
Triton and Pluto are believed to share a common origin, both forming initially in the Kuiper Belt but Triton being later captured by Neptune. Both objects display similar sizes, densities, […]
