What's happening in the depths of distant worlds?

The physics and chemistry that take place deep inside our planet are fundamental to the existence of life as we know it. But what forces are at work in the interiors of distant worlds, and how do these conditions affect their ...

Tackling a 40 million-year-old conundrum

Silicate minerals are the major components of most rocks. When these minerals on the Earth's surface come into contact with water, they partially dissolve as they react with carbon dioxide in the water. This dissolved material ...

Mountain growth influences greenhouse effect

Taiwan is an island of extremes: severe earthquakes and typhoons repeatedly strike the region and change the landscape, sometimes catastrophically. This makes Taiwan a fantastic laboratory for geosciences. Erosion processes, ...

Making simulated cosmic dust—in the microwave

Cosmic dust is the key to the chemical evolution of stars, planets, and life itself, but its composition is not well understood, and we can't currently collect samples for analysis. A few examples have arrived on Earth as ...

Why is the Earth's F/Cl ratio not chondritic?

Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental ...
