A new study of radar experiment data from the Cassini-Huygens mission to Saturn has yielded fresh insights related to the makeup and activity of the liquid hydrocarbon seas near the […]

The Solar System Could Have Formed in a Low-viscosity Disc: A Dynamical Study From Giant Planet Migration to the Nice Model
In the context of low-viscosity protoplanetary discs (PPDs), the formation scenarios of the Solar System should be revisited. In particular, the Jupiter-Saturn pair has been shown to lock in the […]
A Simplified Model for the Forced Libration of Icy Moons with Subsurface Oceans: Application to Enceladus and Mimas
In this work, we investigate a minimalist model capable of accurately replicating the forced librations of an icy moon with a subsurface ocean.
A Pole-to-Pole Map Of Hydrocarbons In Saturn’s Upper Stratosphere And Mesosphere
We analyze data from the final two years of the Cassini mission to retrieve the distributions of methane, ethane, acetylene, ethylene, and benzene in Saturn’s upper stratosphere and mesosphere from […]
Formation Of The Four Terrestrial Planets In The Jupiter-Saturn Chaotic Excitation Scenario: Fundamental Properties And Water Delivery
The Jupiter-Saturn chaotic excitation (JSCE) scenario proposes that the protoplanetary disk was dynamically excited and depleted beyond ~1-1.5 au in a few Myr, offering a new and plausible explanation for […]
Radio Observations As An Extrasolar Planet Discovery and Characterization: Interior Structure and Habitability
Detection of radio emission from Jupiter was identified quickly as being due to its planetary-scale magnetic field. Subsequent spacecraft investigations have revealed that many of the planets, and even some […]
Dragonfly Rotorcraft Astrobiology Mission To Titan Confirmed
NASA has confirmed its Dragonfly rotorcraft mission to Saturn’s organic-rich moon Titan. The decision allows the mission to progress to completion of final design, followed by the construction and testing […]
Orbital Eccentricity Led To A Young Underground Ocean On Mimas
Saturn’s moon Mimas could have grown a huge underground ocean as its orbital eccentricity decreased to its present value and caused its icy shell to melt and thin.
Signs Of Life Are Detectable In A Single Ice Grain Emitted From Icy Moons
The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of […]
Water-Ice Dominated Spectra of Saturn’s Rings and Small Moons from JWST
JWST measured the infrared spectra of Saturn’s rings and several of its small moons (Epimetheus, Pandora, Telesto and Pallene) as part of Guaranteed Time Observation program 1247.
