Open AccessCassini spacecraft reveals global energy imbalance of saturn
The global energy budget is pivotal to understanding planetary evolution and climate behaviors. Assessing the energy budget of giant planets, particularly those with large seasonal cycles, however, remains a c...

Open AccessScience goals and new mission concepts for future exploration of Titan’s atmosphere, geology and habitability: titan POlar scout/orbitEr and in situ lake lander and DrONe explorer (POSEIDON)
In response to ESA’s “Voyage 2050” announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn’s largest moon Titan. Titan, a “wo...

The seasonal cycle of Titan's detached haze
Titan's ‘detached’ haze, seen in Voyager images in 1980 and 1981 and monitored by the Cassini Imaging Science Subsystem (ISS) during the period 2004–2017, provides a measure of seasonal activity in Titan’s mes...

Temperature, Clouds, and Aerosols in Giant and Icy Planets
As observations (transit spectra and secondary eclipse spectra) of extrasolar planets accumulate, it has become clear that clouds and haze are prevalent in the Neptune–Jupiter-sized planets. Clouds and haze ha...

Haze cools Pluto's atmosphere
Modelling suggests that Pluto's atmospheric temperature is regulated by haze, unlike the other planetary bodies in the Solar System. The finding has implications for our understanding of exoplanetary atmospher...

Open AccessAerosol influence on energy balance of the middle atmosphere of Jupiter
Aerosols are ubiquitous in planetary atmospheres in the Solar System. However, radiative forcing on Jupiter has traditionally been attributed to solar heating and infrared cooling of gaseous constituents only,...

Open AccessStrong Temporal Variation Over One Saturnian Year: From Voyager to Cassini
Here we report the combined spacecraft observations of Saturn acquired over one Saturnian year (~29.5 Earth years), from the Voyager encounters (1980–81) to the new Cassini reconnaissance (2009–10). The combin...

Equatorial winds on Saturn and the stratospheric oscillation
The stability over time of the zonal jets on the giant planets has been debated. An analysis of observations from the Cassini spacecraft reveals an acceleration of wind velocities in Saturn’s high-altitude equ...

Aerosols in Titan's Atmosphere
Aerosols in Titan's atmosphere play important roles in the transfer of solar and thermal radiation, in Titan's heat balance, in forcing atmospheric dynamics, and as a sink for photochemical reactions. In this ...
