A team of researchers has produced the strongest experimental evidence yet that Earth’s iron core holds enormous quantities of hydrogen, potentially equivalent to 9 to 45 oceans’ worth of water. The ...
Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...
An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core. A team led by scientists from ...
