The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

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 surface ...

Earth's solid inner core, which helps to strengthen its magnetic field, formed about 1.3 billion years ago when the planet was already 3.2 billion yeas old, a study claims. The development of this ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

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 assumed, ...

It is already well known that Earth has an inner core – a solid metallic ball made mainly of iron around 1,500 miles wide. But a new study shows there is another dense sphere within this core – an ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

Scientists have discovered that Mars has an interior structure similar to Earth’s. Results from Nasa’s Insight mission suggest that the red planet has a solid inner core surrounded by a liquid outer ...

Just like the Earth, the Moon has a solid, iron inner core in addition to its fluid outer core. This is the conclusion of a study by researchers from France, who created various models of the lunar ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...
