Is there something strange and alien confined deep inside the Earth? Is it trying to break free and escape into the heavens?

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

How does the inside of the Earth stay boiling hot for billions of years? Henry, age 11, Somerville, Massachusetts Our Earth is structured sort of like an onion – it’s one layer after another. Starting ...

By comparing their results to different models of the Earth's interior, Professor Tkalčić and Dr Ma found that this was best explained by the presence of a vast underground 'torus', or donut ...
