It’s core to life on Earth.
The Earth's core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
The Earth has a powerful magnetic field.
A strange patch of extremely strong magnetic field occurred over Jordan in 1000BC. Could we be about to face another one?
Signals from violent earthquakes are helping reveal the landscape of the planet's insides.
What’s north would become south.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
Dating the Earth’s enigmatic inner core: a Pluto-sized ball of iron that is super hot and frozen at the same time.
The Earth's inner core is more than half a billion years older than previously thought, shows a study. The results could help us better understand the processes that shape the planet's surface.
No Earths were harmed in the making of this image.
The discovery of a thickly viscous layer which traps sinking plates below Earth's surface has wide implications, not least as a cause of earthquakes.
Magnetic traces suggest iron crystals in the innermost core are aligned east-west, rather than north-south.
