Do Uranus’s Moons Have Subsurface Oceans? “In the field of planet formation, we’re not starved for ideas, but we’re starved for actual constraints on the ideas.”Sean Raymond, “Giant Planet’s Formation Caught in Action“ SPACE & PLANETS ARCHIVE 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. by Morgan Rehnberg 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. by Morgan Rehnberg 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. by Carolyn Wilke 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. by Katherine Kornei 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. by Viviane Pierrard 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. by Andrew Poppe 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. by Katherine Kornei 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. by Jure Japelj 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. by Kimberly M. S. Cartier 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. by Katherine Kornei Load more posts Loading… Something went wrong.
