Saturn's tilt caused by its moons
Two scientists from CNRS and Sorbonne University working at the Institute of Celestial Mechanics and Ephemeris Calculation (Paris Observatory - PSL/CNRS) have just shown that the influence of Saturn's satellites can explain the tilt of the rotation axis of the gas giant. Their work, published on 18 January 2021 in the journal Nature Astronomy, also predicts that the tilt will increase even further over the next few billion years. (2021-01-20)

Testing the waters: Analyzing different solid states of water on other planets and moons
Aside from regular ice, water can exist in the form of peculiar solids called clathrate hydrates, which trap small gaseous molecules. They play a large role in the evolution of atmospheres, but predicting their presence in cryogenic temperatures is difficult. In a recent study, scientists from Okayama University developed statistical mechanics theory to determine their presence in Pluto and some of Jupiter's and Saturn's satellites, providing valuable information to revise existing interpretations.

Origin of massive methane reservoir identified
New research provides evidence of the formation and abundance of abiotic methane -- methane formed by chemical reactions that don't involve organic matter -- on Earth and shows how the gases could have a similar origin on other planets and moons, even those no longer home to liquid water. (2019-08-20)

At the edge of chaos: New method for exoplanet stability analysis
Gaining a full understanding of systems of exoplanets and distant stars is difficult, because the initial positions and velocities of the exoplanets are unknown. Determining whether the system dynamics are quasi-periodic or chaotic is cumbersome, expensive and computationally demanding. In this week's Chaos, Tamás Kovács delivers an alternative method for stability analysis of exoplanetary bodies using only the observed time series data to deduce dynamical measurements and quantify the unpredictability of exoplanet systems. (2019-07-30)

Super salty, subzero Arctic water provides peek at possible life on other planets
A UW team has discovered thriving communities of bacteria in Alaskan 'cryopegs,' trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn's moon Titan, or other bodies farther from the sun. (2019-07-12)

SMU's 'Titans in a jar' could answer key questions ahead of NASA's space exploration

Astronomers see 'warm' glow of Uranus's rings
Two telescopes have measured the faint heat from the main, or epsilon ring, of Uranus, enabling astronomers for the first time to determine its temperature: a cool 77 Kelvin. Earlier images of the rings came from reflected light only. The observations by teams at UC Berkeley and the University of Leicester also show that the rings lack dust, which is common in the rings of other planets, and are comprised of centimeter-sized particles and larger.
