Large impact basins on the near side of the Moon lack the annulus of thickened crust that far-side basins have. The difference can be linked to the thermal structure of the lunar crust.
A new analysis strategy sheds new light on the electrical conductivity of the lunar mantle between 300 and 900 km depth.
A new seismic survey of the Chicxulub impact crater reveals the structure of its peak ring and the sediments that cover it.
Even the strong heating from short-lived aluminium-26 (26Al) would not be able to homogenize the interior of a Mars‐sized planetary embryo.
Mapping boulder fields and boulder tracks highlights the seismic hazard still present on the Moon.
Although Venus does not have plate tectonics today, previous episodes of intense tectonic activity could have resulted in a distribution of crustal thickness and age resembling the plate we see today.
Models link the variety of crater shapes expected on (16) Psyche with the interior structure of this unique asteroid, in preparation for the arrival of the Psyche probe in 2026.
Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.
When the lander MASCOT, carried by Hayabusa2, touched down on asteroid Ryugu, it did not detect a magnetic field, even though meteorites that are spectroscopically similar to Ryugu have trace of one.
Three billion years ago, on Mars, the shores of an ocean may have been flooded by a mega-tsunami. Now the crater left by the bolide impact that probably triggered the tsunami has been identified.
