A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that the moon has a solid inner core, similar to Earth’s, composed of iron with a ...

Deep beneath the Earth's surface, the inner core has long been thought of as a solid sphere, steadily growing as the outer core cools and crystallizes. However, a new study suggests that the inner ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications. Data from NASA's InSight mission has revealed that ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our understanding of lunar history and cosmic origins.

The change in shape could be happening where the edge of the solid inner core touches the extremely hot liquid metal outer core. The research is published in the scientific journal Nature Geoscience.

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Earth’s inner core is less solid than previously thought, reveals new research. American scientists have detected structural changes near the planet’s center. Changes to the inner core have ...
