In recent research published by myself and my colleague Tony Yeates in the journal Tectonophysics, we investigate what we believe – based on many years of experience in asteroid impact research – is ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, ...

More insights about Earth's core have arrived through some detailed examinations. A team of researchers believes that the inner core is made of two distinct layers. The finding has been explained in ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

The Earth has a shell-like structure. It is divided into a core (inner and outer core), a mantle (lower and upper mantle, separated by a transition zone), and the earth's crust. You are free to share ...

We know more about the surfaces of other planets than we do about what's inside our own. No drill has ever penetrated Earth's crust, which averages 25 miles thick beneath the continents. So, virtually ...

Climate change is having an increasing impact on the structure of Earth's atmosphere, a new international study shows. The research draws on decades of observations to quantify that warming ...
