The weather layers of the gas giant planets, Jupiter and Saturn, comprise the shallow atmospheric layers that are influenced energetically by a combination of incoming solar radiation and localised…
Multilayer hazes over Saturn’s hexagon from Cassini ISS limb images
- Environmental Science, PhysicsNature Communications
- 2020
A system of multi-layered hazes above Saturn’s hexagonal-wave cloud tops in the visual range is analyzed, suggesting the formation to be caused by condensation processes, and the vertical distribution of stacked layers by the upward propagation of internal gravity waves.
Features of Saturn’s Equinox in 2010

Abstract— The equator of Saturn is inclined to the orbital plane by an angle of 26.75°, and the period of revolution around the Sun is 29.45 years. Since the orbital eccentricity of Saturn is e ≈…
Deep rotating convection generates the polar hexagon on Saturn
- PhysicsProceedings of the National Academy of Sciences
