The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's surface ... Further out is the mesosphere, and after that, the thermosphere, which begins the transition into ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Underneath the Earth’s crust we know there is a hot mantle and an even hotter outer and inner core, but now experts say we ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

The temperature can change from very hot to very cold, depending on sunlight exposure. It can range from 1,700°C (3,092°F) in the sun to -270°C (-454°F) in the shade.

Rover Spots Possible Evidence of Liquid Water on Modern Mars The radar data revealed underground rock layers bearing a striking resemblance to geological structures on Earth called “foreshore ...

An asteroid that could level a city now has a 3.1-percent chance of striking Earth in 2032, according to NASA data released Tuesday — making it the most threatening space rock ever recorded by ...

Instead, the results suggest that there is much less flow within the mantle than previously believed. Earth’s mantle is the thick layer between the crust and the core. It includes a graveyard of ...
