A system of categorization that reflects not just a mineral's chemistry and crystalline structure, but also the physical, chemical, or biological processes by which it formed, would be capable of recognizing that nanodiamonds from space are fundamentally different from diamonds formed in Earth's depths.

Catharine “Cassie” Conley joins us from NASA as a visiting scientist working with Andrew Steele.

Geochemistry

In shock-wave experiments, high-powered lasers or guns are used to send a supersonic pressure wave through a sample. This type of dynamic compression can generate immense pressure and allows for the study of impact phenomena in real time.

Planetary Science

Gravity, the fundamental force that shaped our planet, varies across the Earth’s surface, both from place to place and over time. For more than three centuries, scientists have made gravity measurements to define the shape of the Earth.

Planetary Science

As extreme weather, rising seas, and severe droughts bring home the reality of global climate change, we are increasingly aware of the world’s pressing need for carbon-free energy sources and reliable, affordable energy storage systems. 

Planetary Science

Simon Lock of the California Institute of Technology is interested in the formation, structure, and evolution of planets, both in our solar system and in extrasolar systems.

Geochemistry

The research of Associate Professor at Brown University Stephen Parman focuses on the chemical evolution of the Earth, moons, and planets. He will deliver a seminar titled "Tracing volatile recycling in the mantle with noble gases."

Planetary Science

The Geophysical Laboratory's weekly seminar series continues with Heather Watson of Union College, Department of Physics and Astronomy. She will present on "Diffusion of key isotopes in iron meteorites: Constraints on closure temperatures."
