New single crystal paleointensity data show that the geomagnetic field was renewed in the early Cambrian after near collapse in the Ediacaran Period. This implies that the innermost/outermost structure of the inner core formed 450 million yrs. ago.

Tungsten isotopes between the Earth and Moon are compared in this new study. The authors find that traditional models of Moon formation are very unlikely to reproduce the Moon's Earth-like isotopic composition.

Pluto’s subsurface ocean may have formed early due to accretionary heating, a comparison of thermal evolution modelling with observed tectonic structures suggests.

A late onset of inner-core growth is inferred from ultra-low palaeomagnetic field strengths about 565 million years ago, as measured in magnetic inclusions in Ediacaran crystals.

Reanalysis of radiometric data from Cassini indicates that Titan does not contain a subsurface ocean, as strong tidal dissipation observed in its gravity field is not consistent with the presence of a liquid layer.

Lunar rock and zircon ages were reset by a remelting event driven by the Moon’s orbital evolution, reconciling existing discrepancies in estimates for the formation time of the Moon and the crystallization time of its magma ocean.

Analysis of the Moon's topography reveals that when its largest basins are removed, the lunar shape is consistent with processes controlled by early Earth tides, and implies a reorientation of the Moon's principal shape axes.

Water plume eruptions on Saturn’s icy moon Enceladus are delayed relative to the peak tidal stresses. Simulations suggest the delay can be explained by the moon’s interior structure and the presence of a subsurface ocean.

Saturn’s satellite Enceladus shows higher heat loss than expected and a wide range of surface ages. Numerical simulations indicate that occasional catastrophic overturn events could be responsible for both observations by recycling portions of the icy lid to the interior, which would cause transiently enhanced heat loss.

Magnetic palaeointensity data from the Barberton Greenstone Belt (South Africa) as well as the Jack Hills (Western Australia) show nearly constant palaeofield values between 3.9 Ga and 3.4 Ga, providing evidence for stagnant-lid mantle convection.

The New Horizons mission has revealed Pluto and its moon Charon to be geologically active worlds. The familiar, yet exotic, landforms suggest that geologic processes operate similarly across the Solar System, even in its cold outer reaches.

Volcanism in the enormous Tharsis region on Mars migrated from south to north. Numerical modelling suggests that this migration as well as the current location of the region can be explained by net rotation of the lithosphere relative to the mantle.

Giant icy volcanos (cryovolcanos) on Pluto are unique in the imaged solar system and provide evidence for unexpected, active geology late in Pluto’s history.

Pluto’s subsurface ocean and thickness variation in its ice shell may be maintained by a layer of methane clathrates forming an insulating cap to the ocean, according to calculations of thermal evolution and viscous relaxation.

The volatile-ice-filled basin informally named Sputnik Planum is central to Pluto’s geological activity; this ice layer is organized into cells or polygons, and it is now shown that convective overturn in a several-kilometre-thick layer of solid nitrogen can explain both the presence of the cells and their great width.

Molecular diagnostics for tuberculosis have focused on predicting drug susceptibilities in a binary manner (i.e., strains are either susceptible or resistant). Here, CRyPTIC Consortium researchers use whole genome sequencing and a quantitative assay to identify associations between genomic mutations and minimum inhibitory concentrations in over 15,000 Mycobacterium tuberculosis clinical isolates.

More than 20 GW of power are necessary to balance the heat emitted by Enceladus and avoid the freezing of its internal ocean. A very porous core undergoing tidal heating can generate the required power to maintain a liquid ocean and drive hydrothermal activity.

Calculating the age of the Earth's solid inner core has proved to be a tricky business. But the suggestion that there is more potassium in the core than had been thought could help to reconcile differing estimates.

Experiments show that magnesium oxide can dissolve in core-forming metallic melts at very high temperatures; core formation models suggest that a giant impact during Earth’s accretion could have contributed large amounts of magnesium to the early core, the subsequent exsolution of which would have generated enough gravitational energy to power an early geodynamo and produce an ancient magnetic field.

The measurement of magnesium isotope ratios at improved accuracy suggests that planetary compositions result from fractionation between liquid and vapour, followed by vapour escape during accretionary growth.

Nanomagnetic imaging has been used to obtain a palaeomagnetic time series of two pallasite meteorites, revealing that their convection was driven by core solidification, which would have caused long-lived magnetic fields in the cores of early Solar System planetary bodies.

Single-crystal paleointensity measurements of Apollo samples suggest that if the Moon’s core produced a magnetic field, it disappeared by 4.36 billion years ago, possibly allowing a record of Earth’s Hadean atmosphere to be preserved in the lunar regolith.

An ultra-weak magnetic field from Earth’s core lasting for at least 26 million years may have contributed to Earth’s oxygenation and further diversification of the Ediacaran fauna, according to single-crystal paleointensity data from igneous rocks in South Africa and Brazil.

Geophysical and meteorological measurements by NASA’s InSight lander on Mars reveal a planet that is seismically active and provide information about the interior, surface and atmospheric workings of Mars.

A network of parallel ridges on the northwestern border of Sputnik Planitia on Pluto are the traces of debris material deposited by a glaciation of icy nitrogen that happened early in Pluto’s history, and left there once the N₂ ice disappeared by sublimation.
