Washington, DC— The discovery that our galaxy is teeming with exoplanets has also revealed the vast diversity of planetary systems out there and raised questions about the processes that shaped them. New work published in Science by an international team including Carnegie’s Jaehan Bae could explain the architecture of multi-star systems in which planets are separated by wide gaps and do not orbit on the same plane as their host star’s equatorial center.

“In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline—sometimes a very steep one,”

Washington, DC— The composition of Earth’s mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie’s Jonathan Tucker and Peter van Keken along with colleagues from Oxford that was recently published in Geochemistry, Geophysics, Geosystems.

During its evolution, our planet separated into distinct layers—core, mantle, and crust. Each has its own composition and the dynamic processes through which these layers interact with their neighbors can teach us about Earth’s geologic history.

Plate tectonic processes allow for continuous evolution of the crust and play a key role in our planet

Washington, DC— When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions found deep inside the planet?

New work led by Carnegie’s Sally June Tracy examined the crystal structure of the silica mineral quartz under shock compression and is challenging longstanding assumptions about how this ubiquitous material behaves under such intense conditions. The results are published in Science Advances.

Washington, DC— In September, astronomer Johanna Teske will join Carnegie’s Earth and Planets Laboratory as a Staff Scientist. Teske has been with Carnegie since 2014, first as the inaugural Carnegie Origins Postdoctoral Fellow and currently as a NASA Hubble Fellow. 

“I’m thrilled to be able to continue my career at Carnegie and to be the first Staff Scientist hired at the newly formed EPL,” Teske said. “This institution has shaped my approach to research and I am excited to advance to the next stage of my career as one of its faculty.”

Established in June of 2016 with a generous gift of $50,000 from Marilyn Fogel and Christopher Swarth, the Marilyn Fogel Endowed Fund for Internships will provide support for “very young budding scientists” who wish to “spend a summer getting their feet wet in research for the very first time.”  The income from this endowed fund will enable high school students and undergraduates to conduct mentored internships at Carnegie’s Geophysical Laboratory and Department of Terrestrial Magnetism in Washington, DC starting in the summer of 2017.

Carbon plays an unparalleled role in our lives: as the element of life, as the basis of most of society’s energy, as the backbone of most new materials, and as the central focus in efforts to understand Earth’s variable and uncertain climate. Yet in spite of carbon’s importance, scientists remain largely ignorant of the physical, chemical, and biological behavior of many of Earth’s carbon-bearing systems. The Deep Carbon Observatory (DCO) is a global research program to transform our understanding of carbon in Earth. At its heart, DCO is a community of scientists, from biologists to physicists, geoscientists to chemists, and many others whose work crosses these

Alan Linde is trying to understand the tectonic activity that is associated with earthquakes and volcanos, with the hope of helping predictions methods.  He uses highly sensitive data that measures how the Earth is changing below the surface with devises called borehole strainmeters that measure tiny strains the Earth undergoes.

Strainmeter data has led to the discovery of events referred to as slow earthquakes that are similar to regular earthquakes except that the fault motions take place over much longer time scales. These were first detected in south-east Japan and have since been seen in a number of different environments including the San Andreas Fault in California and

Hélène Le Mével studies volcanoes. Her research focuses on understanding the surface signals that ground deformations make to infer the ongoing process of the moving magma  in the underlying reservoir. Toward this end she uses space and field-based geodesy--the mathematics of the area and shape of the Earth--to identify, model and interpret this ground deformation.

She uses data from radar called Interferometric Synthetic Aperture Radar (InSAR), and data from the Global Positioning System (GPS) to characterize ground motion during volcanic unrest. She also collects gravity data, which indicate changes in mass and/or density underground. These data sets,

What sets George Cody apart from other geochemists is his pioneering use of sophisticated techniques such as enormous facilities for synchrotron radiation, and sample analysis with nuclear magnetic resonance (NMR) spectroscopy to characterize hydrocarbons. Today, Cody  applies these techniques to analyzing the organic processes that alter sediments as they mature into rock inside the Earth and the molecular structure of extraterrestrial organics.

Wondering about where we came from has occupied the human imagination since the dawn of consciousness. Using samples from comets and meteorites, George Cody tracks the element carbon as it moves from the interstellar medium, through

Some 40 thousand tons of extraterrestrial material fall on Earth every year. This cosmic debris provides cosmochemist Conel Alexander with information about the formation of the Solar System, our galaxy, and perhaps the origin of life.

Alexander studies meteorites to determine what went on before and during the formation of our Solar System. Meteorites are fragments of asteroids—small bodies that originated between Mars and Jupiter—and are likely the last remnants of objects that gave rise to the terrestrial planets. He is particularly interested in the analysis of chondrules, millimeter-size spherical objects that are the dominant constituent of the most primitive
