Giant Planets May Be “Agents of Chaos”
Two studies suggest that some giants could make it difficult or even impossible for terrestrial planets to remain in a star’s habitable zone.
Astronomers May Have Spotted the Birth of a Planet
Lumps of dust are spiraling around a young star 5,000 light-years away. They could be Jupiter-like planets in the making.
Visualizing the Deep Insides of Planets and Moons
A novel method uses gravity data to determine where density anomalies lie inside planetary bodies.
Air Flow Dynamics in Wet Soils: Challenges and Knowledge Gaps
Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.
Nearby Volcano Planet Likely Fueled by Tidal Heating
A gravitational dance between a newly discovered exoplanet and its host star may be driving extreme volcanism on its surface.
Wind Shear Instabilities Emit Gravity Waves
A new study shows that atmospheric gravity waves can be generated by the Kelvin-Helmholtz instabilities in the wind shear layer.
Quaoar’s Ring Defies Gravity
The dwarf planet’s ring makes astronomers question whether a long-held theory about ring and moon formation needs tweaking.
Months of Gravity Changes Preceded the Tōhoku Earthquake
Using GRACE satellite data, researchers discovered anomalous gravimetric signals that occurred before a seismic event that started deep within Earth.
