Latest Planetary core Stories
Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.
The inner core of the Earth is simultaneously melting and freezing due to circulation of heat in the overlying rocky mantle, according to new research from the University of Leeds, UC San Diego and the Indian Institute of Technology.
A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground.
Priceless treasure from the bottom of the sea is locked away at Texas A&M University, stacked on floor-to-ceiling racks and kept secure in 15,000 square feet of refrigerated space.
In a recent paper published in Nature Geoscience (*), the geophysicist Mioara Mandea from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earthâ€™s core are changing surprisingly fast, and that this, in turn, effects the magnetic field of our Planet.
New scientific evidence suggests that deep inside the planet Mercury, iron â€œsnowâ€ forms and falls toward the center of the planet, much like snowflakes form in Earthâ€™s atmosphere and fall to the ground.
Geologists at the University of Illinois have confirmed the discovery of Earthâ€™s inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core.
UC Davis researchers studying cores of sediment collected 40 years ago have found evidence for magnetic field vortices in the Earth's core beneath the South Pole. The results contrast with earlier studies at lower latitudes, and could lead to a better understanding of processes in the core.
A University of Toronto-led study has uncovered tiny zircon crystals in a meteorite originating from Vesta (a large asteroid between Mars and Jupiter), shedding light on the formation of planetesimals, small astronomical objects that form the basis of planets.
