New research confirms the existence of a regular, long-term fluctuation in sea level, perhaps caused by processes in Earth’s core.
Saturn’s oddly symmetrical magnetic field can be explained by models in which the active dynamo region is overlain by a thick, stable layer cooled more strongly at the poles.
New simulations of Earth’s outer core have reproduced magnetic fields that—for the first time—match paleomagnetic data collected from rocks.
The strength of Earth’s magnetic field in the distant past can tell scientists whether the planet’s magnetic poles were steady or prone to frequent reversals.
How old is Earth’s inner core? High-pressure and high-temperature experiments suggest that our planet’s inner furnace may be much younger than expected.
A new tomographic method based on correlations of seemingly chaotic earthquake coda waves yields otherwise unobservable arrivals, thus greatly improving illumination of the deep Earth.
New research using a highly complete earthquake catalog shows that 72% of M4+ mainshocks are preceded by foreshocks, implying that foreshock activity is much more prevalent than previously thought.
Silicate melts containing H2O in the lowermost mantle are surprisingly dense and may stagnate there, trapping primordial volatiles and potentially causing some of the ultra-low velocity zones.
