Ancient Venus Plate Tectonics Revisited
Our research, recently published in Nature Astronomy, sheds light on Venus, a planet with many mysteries. Despite its sweltering conditions...
Origins of Asteroid 16 Psyche
M-type asteroids, of which 16 Psyche is the largest, are generally believed considered to have metal-rich surfaces. The masses, and...
Deciphering the Early Lunar Dynamo
Remanent magnetization of the lunar crust and samples indicates the past existence of an ancient, internally generated magnetic field on...
Tectonics on Venus
Venus, although very similar to Earth in many ways, has undergone a very different geologic evolution. The geologic and thermal...
Structure of Icy Worlds
The moons of Jupiter are some of the most confounding bodies in the Solar System. Ganymede and Callisto, for example,...
Geodynamics of Ceres

Consequences of Lunar Magma Ocean
Several theories have been advanced to explain the origin of the lunar hemispheric dichotomy – an asymmetry between the...
Exoplanet Habitability
With numerous terrestrial-like exoplanets discovered from the Kepler mission, ranging from ~0.5 to ~2 Earth Radius, it is natural to...
Ferrovolcanism
Recent work suggests that solidification of the 100 km radius core of a mostly mantle-stripped body may progress from the...
Lunar Basin Structures
The formation of impact basins played a dominant role in the evolution of ancient planetary crusts. Despite their importance, the...
Early Lunar Chronology with GRAIL
Establishing the absolute and relative chronology of ancient lunar events is of fundamental importance to our understanding of early Solar...
Mars: Coupling Magmatism and Habitability
Several lines of evidence suggest that water – an essential requirement for known life – was once abundant at the...
Mercury: Volcanism & Mantle Dynamics
Analyses of Mercury’s surface by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft have identified a large portion...
GRAIL Reveals Beneath the Lunar Maria
With gravity data acquired by the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft, in conjunction with altimetry data from...
Water in the Deep Moon
Until recently, the Moon had been thought to have a relatively low volatile content due to a combination of its...
Erosion on Mars
Arabia Terra, with an area of approximately 10 million square kilometers centered at (25E, 5N), is an anomalous region along...
