Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

Earth's inner core may have changed shape, according to researchers studying unknown transformations deep within the planet.

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

The Sun, being the perfect storm of "really far" and "really hot", makes it pretty difficult to study its interior structure. But like we can study the Earth's interior by looking at seismic waves ...

Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

Many geologists attribute the great variation in the temperature gradient to complex irregularities in the structure of the earth's crust. Some even maintain that the interior of the earth is cold ...

In a nutshell Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme ...

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found lurking below Africa and the Pacific Ocean, entombed some 1,200 miles below the ...

Potential patches of Earth's ancient crust, sometimes called "sunken worlds," may have just been discovered deep within the mantle, thanks to a new way of mapping the inside of our planet.

Seismologists study Earth’s deep interior by investigating how much these tones are ‘out of tune’, because whole Earth oscillations will sound out of tune or less loud when they encounter ...
