Constraints on the Feasibility of Ferrovolcanism on Asteroid 16 Psyche
Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.Abstract Asteroid 16 Psyche's surface appears to be highly metallic, but its bulk density suggests a silicate‐rich interior. Ferrovolcanism has been suggested to explain how a silicate‐rich body could develop a metallic surface. This requires trapping of light elements bearing iron‐rich metallic melt in a core solidifying from the outside inwards.

Paleoceanography and Paleoclimatology, Volume 40, Issue 8, August 2025.Abstract Variations in Earth's orbit and axial tilt induce climatic changes which are recorded in sedimentary deposits. The frequencies of these cyclical variations are integer combinations of the main secular frequencies of the solar system. Analyzing these cycles in sedimentary records can help establish an astronomical time scale for the geological ...

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.Abstract Remote sensing data were deployed to create a lineament map (LM) of central Quebec, Canada. The LM provides a first‐order representation of the geological structures and is shown to co‐align with 45% of the structural features previously mapped in the area.

Ferromagmatic Intrusions on Asteroid (16) Psyche May Be Magnetized
Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.Abstract NASA's Psyche mission will arrive at the metal‐rich asteroid (16) Psyche in 2029. The mission will test whether (16) Psyche is a remnant of a melted, differentiated planetesimal that formed a molten iron metallic core. Previous studies have suggested that a molten metallic core fluid could erupt volcanically, explaining the high metal content ...
