Dynamics of Ocean Worlds Likely Controlled by Their Rotation
New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
Encontrando los océanos ocultos de las lunas usando campos magnéticos inducidos
Un análisis de componentes principales de modelos especulativos puede predecir con más seguridad que las técnicas anteriores la p^ppresencia de un océano subsuperficial en un objeto planetario.
Krypton Isotopes Provide New Clues to Planets’ Pasts
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
Pluto’s Surface Was Recently Sculpted by Icy Volcanism
Geologically young regions of Pluto’s southern hemisphere were likely resurfaced by cryovolcanism, data from the New Horizons spacecraft reveal.
Meteoric Ions Influence Conductance in the Jovian Ionosphere
Meteoric ions dominate the Jovian lower ionosphere due to their long lifetimes. Due to the large densities of the meteoric ions, conductance is enhanced independently of local time.
Life on Mars? Estimating Radiation Risks for Martian Astronauts
New research suggests that to minimize radiation risk for human exploration of Mars, astronauts will need to dig deep for safety.
Impact Structure Hidden Under Arctic Ice Dates to the Paleocene
Greenland’s Hiawatha impact structure, more than 30 kilometers in diameter, is much older than previously thought, new results suggest.
Giant Planet’s Formation Caught in Action
Astronomers took a direct image of a massive protoplanet embedded in a protoplanetary disk. The system provides strong evidence for an as-yet-unconfirmed theory of planet formation.
Mars’s Dust Cycle Controls Its Polar Vortex and Snowfall
On Earth, the water cycle is a dominant climate force. On Mars, it’s the dust.
Saturn’s Powerful Winds Explain Changes in the Length of Its Day
Atmospheric winds moving at more than 7,000 kilometers per hour distort Saturn’s magnetic field, revealing why spacecraft have measured changes in the length of a day on the ringed world.
