Mars may have a hardened heart. Marsquake reverberations detected by NASA’s InSight lander revealed that the Red Planet probably possesses a solid inner core, researchers report in the Sept. 4 Nature.

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird acceleration of seismic waves. Experiments recreating the phenomenon in a ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Deep under Africa and the central Pacific lie clusters of geological ...

Mars’ heart is about the size of our moon, and almost twice as dense. Or so suggest the first observed rumblings from a Marsquake and meteorite impact to cross the Red Planet’s heart, researchers ...

Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface. For the decades since ...

Structures that scatter seismic waves deep in Earth's mantle seem to be everywhere researchers look. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

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 ...

The Vandenberg Space Force Base in Santa Barbara, California, serves military space launch missions as well as launches for NASA and commercial entities like SpaceX. But how do all those launches ...
