The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the ...

This undated illustration shows Earth's inner core. Scientists say that around 565 million years ago, the planet's solid inner core emerged, making life on Earth a possibility.

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have questions, though. US hiring picked up in June, defying economists ...

In June 2024, USC scientists published a study showing that Earth’s inner core has been slowing since 2010. This deceleration slightly affects the planet’s rotation, leading to marginally longer days.

The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer boundary has ...

Recently, scientists have discovered that the Earth's inner core thought to be in a solid state and also an unchanging sphere, may have undergone significant shape changes over the past 20 years.

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

Mars may have a solid inner core within its liquid outer core, according to a new analysis of the planet’s seismic activity. This could help solve several enigmas about Martian geology – but ...
