Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an unusual “buttery” state of matter, one that challenges long-standing ...

Earth’s inner core is surprisingly soft, and wiggling iron atoms may help explain why. The innermost part of our planet is a solid iron ball smaller than the moon and almost as hot as the surface of ...

The Earth’s inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet. The snow is made of ...

A model of iron atoms on the move in Earth's inner core. The model demonstrates how iron atoms are expected to move about in the Earth’s inner core over 10 picoseconds.. One picosecond is one ...

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from snapping the moon in half to causing a gravitational wave apocalypse – and subjects them to the ...

If the explorers from Journey to the Center of the Earth were to journey to the center of Mars instead, they definitely wouldn’t come across the subterranean oceans or live dinosaurs they encountered ...

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...
