Five key questions in cosmochemistry and geochemistry

Starry night above the Earth

The chemical signatures of rock and space dust hold clues to the deep histories of our planet, Solar System, and life itself—if you know where to look.


Carnegie-led team wins $1.5 million grant to study atmospheres of the galaxy’s most common exoplanets

Carnegie’s Anat Shahar is the lead investigator on an interdisciplinary, multi-institution research team that this spring was awarded nearly $1.5 million from the Alfred P. Sloan Foundation to understand the chemical makeup of our galaxy’s most common planets with a goal of developing a framework for detecting chemical signatures of life on distant worlds.  


Where did Earth's water come from?

As a part of this month's geochemistry/cosmochemistry, Staff Scientist Conel Alexander explains where Earth's water comes from. 


New form of silicon could enable next-gen electronic and energy devices

A team led by Carnegie’s Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic and energy devices with enhanced properties that exceed those of the “normal” cubic form of silicon used today.
