A new seismic survey of the Chicxulub impact crater reveals the structure of its peak ring and the sediments that cover it.
A strategy that combines geologic mapping with data on how the planet’s surface emits and absorbs microwave radiation could potentially identify recent lava flows.
Thermal properties of Martian soil as measured by the InSight lander.
Trapped ions discovered at midlatitudes can have energies exceeding 100 megaelectron volts per nucleon. Their detection adds to our understanding of the powerful radiation environment around Jupiter.
Researchers favor nitrogen ice as the most likely material for the mysterious interstellar object’s composition.
Even the strong heating from short-lived aluminium-26 (26Al) would not be able to homogenize the interior of a Mars‐sized planetary embryo.
An imaging campaign after the 2018 planet-encircling dust storm on Mars revealed a significant increase in detections of enigmatic recurring slope lineae and new insights into how they might form.
Serendipitous observations by the Juno spacecraft while it was en route to Jupiter suggest a Martian source for the dust, but how the dust escapes Mars or its moons remains unknown.
