A team of geologists from China and the US have found evidence to suggest that snow may be falling within the broiling hot core of planet Earth. Of course, this isn’t your everyday surface snow – the ...

The rotation of Earth’s solid inner core may have recently paused relative to the mantle and crust and now appears to be reversing direction, Nikk Ogasa reported in “Earth’s inner core may ‘reverse’ ...

We know more about the surfaces of other planets than we do about what's inside our own. No drill has ever penetrated Earth's crust, which averages 25 miles thick beneath the continents. So, virtually ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...
