(Phys.org)—Periodic comet 17P/Holmes is usually a very faint object. However, during its historic outburst in October 2007, when the comet's coma expanded to a diameter greater than that of the sun, it became visible to ...
Earth's mantle, the large zone of slow-flowing rock that lies between the crust and the planet's core, powers every earthquake and volcanic eruption on the planet's surface. Evidence suggests that the mantle behaves differently ...

University of California, Berkeley, seismologists have produced for the first time a sharp, three-dimensional scan of Earth's interior that conclusively connects plumes of hot rock rising through the mantle with surface hotspots ...

Much of what we understand about earthquakes is based on plate tectonics. But for residents of Utah's seismically restless Wasatch Front, a 120-mile-long metropolitan region anchored by Salt Lake City and bounded by the steep ...

(Phys.org)—A team of researchers working on the Borexino Collaboration at Gran Sasso National Laboratory in Italy is reporting that they have detected neutrinos emanating from the Earth's mantle. In their paper published ...
By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: ...

It was a bit like making a CT scan of a patient's head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic images of the mantle beneath ...

A team of geologists in the U.S. has finally found an analyzable sample of the most abundant mineral in the world allowing them to give it a name: bridgmanite. In their paper published in the journal Science, the team describes ...
