Well, the verdict is in. The Moon is not made of green cheese after all. A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, a solid ball with a density ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

The mystery behind what is inside the Moon, or more specifically, what makes up the inner core of Earth's closest neighbor, may have finally been solved. Newly published research published in the ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the ...

Peering into a hidden metal world Earth’s inner core sits more than 5,000 kilometers below the surface, a solid ball of mostly iron and nickel surrounded by a liquid outer core that powers the ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

In 2019, scientists detected a strange wobble deep below the Earth’s surface that oscillates roughly every 8.5 years. Now, by mapping minute changes in the Earth’s rotation, the team has come up with ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
