A Carnegie-led survey of exoplanet candidates identified by NASA’s Transiting Exoplanets Satellite Survey  (TESS) is laying the groundwork to help astronomers understand how the Milky Way’s most common planets formed and evolved, and determine why our Solar System’s pattern of planetary orbits and sizes is so unusual.

What do you do when you come face-to-face with a seismologist's worst nightmare: battery soup? For the geophysicists at the Earth and Planets Laboratory, it means it's time to innovate. 


EPL’s Top Questions in Geophysics and Geodynamics

Earthquakes and volcanic eruptions are some of the most powerful events on our planet. They remind us that we aren’t standing on “solid ground.” Instead, there are massive machinations and billions of years of planetary evolution at work beneath our feet. They also offer scientists a rare window into the internal workings of our planet.

In this article, EPL’s geophysicists and geodynamicists highlight five questions that we’re working on to better understand the story of our planet.


Behind the Scenes: In the Geophysics Lab with Steven Golden


Steven Golden is an Observational Geophysical Technician at the Carnegie Science Earth and Planets Laboratory. He works with the staff geophysicists Lara Wagner, Diana Roman, and Helene Le Mevel to process and archive seismic, volcanological, and other geophysical data.


Postdoc Spotlight: Nate Sime uses math to study planetary interiors

Nate Sime is a computational physicist who joined Carnegie as a Postdoctoral Fellow in 2018 after receiving his Ph.D. in Mathematics from the University of Nottingham and working for a time as a Research Associate at the ​​University of Cambridge. He builds scalable mathematical models and tools that help shine a light on the complex physical phenomena that built our planet.
