Small magnetic waves have been discovered at Earth's core, with each oscillation working on a seven year cycle. Earth's magnetic field is generated by electric currents generated by the movement of ...

Shaking from large earthquakes provides hints about something different at the center of the planet. By Kenneth Chang The inner core of the Earth appears to hold an innermost secret. Geology textbooks ...

A new study could help us understand how our planet was formed. Scientists report that their research shows that Earth's inner core is solid -- a finding made possible by a new method for detecting ...

Scientists calculated the diameter of Earth's innermost core using earthquake waves that bounced through the planet 'like ping-pong balls.' When you purchase through links on our site, we may earn an ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at ...

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had ...
