Bernard Burke, distinguished MIT astrophysicist and former staff scientist at Carnegie's Department of Terrestrial Magnetism, died August 5. He was 90. 

Burke, who joined the department's in 1953, was an integral member of its astronomy group until he left to be professor of physics at MIT in 1965, where his work shifted to, among other things, the detection of gravitational lensing. He also played a key role in the development of Very Long Baseline Interferometry (VLBI), which enables high-resolution imaging of cosmic structures. He was elected to the National Academy of Sciences in 1970 and served as president of the American Astronomical Society from 1986 to 1988. He was an

Washington, DC—Blue diamonds—like the world-famous Hope Diamond at the National Museum of Natural History—formed up to four times deeper in the Earth’s mantle than most other diamonds, according to new work published on the cover of Nature.

“These so-called type IIb diamonds are tremendously valuable, making them hard to get access to for scientific research purposes,” explained lead author Evan Smith of the Gemological Institute of America, adding, “and it is very rare to find one that contains inclusions, which are tiny mineral crystals trapped inside the diamond.”

Inclusions are remnants of the minerals from the rock in which the diamond crystallized and can tell

Washington, DC—Twelve new moons orbiting Jupiter have been found—11 “normal” outer moons, and one that they’re calling an “oddball.”  This brings Jupiter’s total number of known moons to a whopping 79—the most of any planet in our Solar System.

A team led by Carnegie’s Scott S. Sheppard first spotted the moons in the spring of 2017 while they were looking for very distant Solar System objects as part of the hunt for a possible massive planet far beyond Pluto.  

In 2014, this same team found the object with the most-distant known orbit in our Solar System and was the first to realize that an unknown massive planet at the fringes of our Solar System, far beyond Pluto, could

Washington, DC—A team of scientists including Carnegie’s Michael Ackerson and Bjørn Mysen revealed that granites from Yosemite National Park contain minerals that crystallized at much lower temperatures than previously thought possible. This finding upends scientific understanding of how granites form and what they can teach us about our planet’s geologic history. Their work is published in Nature. 

Granites are igneous rocks comprised predominately of the minerals quartz and feldspar.  They are the link between igneous processes that occur within the Earth and volcanic rocks that solidified on Earth’s surface.

“Granites are the ultimate product of the processes by which

The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) mission to orbit Mercury following three flybys of that planet is a scientific investigation of the planet Mercury. Understanding Mercury, and the forces that have shaped it is fundamental to understanding the terrestrial planets and their evolution. This is the first orbital mission around the innermost planet. It took years of planning and complex trajectory to reach Mercury. Carnegie scientists have led the way revealing results that have redefined what we thought we knew about Mercury and the other rocky planets. For more information see http://messenger.jhuapl.edu/


Following Andrew Carnegie’s founding encouragement of liberal discovery-driven research, the Carnegie Institution for Science offers its scientists a new resource for pursuing bold ideas.

Carnegie Science Venture grants are internal awards of up to $100,000 that are intended to foster entirely new directions of research by teams of scientists that ignore departmental boundaries. Up to six adventurous investigations may be funded each year. The period of the award is two years,

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 disciplinary lines,

Starting in 2005, the High Lava Plains project is focused on a better understanding of why the Pacific Northwest, specifically eastern Oregon's High Lava Plains, is so volcanically active. This region is the most volcanically active area of the continental United States and it's relatively young. None of the accepted paradigms explain why the magmatic and tectonic activity extend so far east of the North American plate margin. By applying numerous techniques ranging from geochemistry and petrology to active and passive seismic imaging to geodynamic modeling, the researchers examine an assemblage of new data that will provide key information about the roles of lithosphere structure,

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, combined with the surface

Volcanologist Diana Roman is interested in the mechanics of how magma moves through the Earth’s crust, and in the structure, evolution, and dynamics of volcanic conduit systems. Her ultimate goal is to understand the likelihood and timing of volcanic eruptions.

Most of Roman’s research focuses on understanding changes in seismicity and stress in response to the migration of magma through volcanic conduits, and on developing techniques and strategies for monitoring active or restless volcanoes through the analysis of high-frequency volcanic seismicity.

Roman is also interested in understanding the seismicity at quiet volcanoes, tectonic and hidden volcanic microearthquake

Peter van Keken studies the thermal and chemical evolution of the Earth. In particularly he looks at the causes and consequences of plate tectonics; element modeling of mantle convection,  and the dynamics of subduction zones--locations where one tectonic plate slides under another. He also studies mantle plumes; the integration of geodynamics with seismology; geochemistry and mineral physics. He uses parallel computing and scientific visualization in this work.

He received his BS and Ph D from the University of Utrecht in The Netherlands. Prior to joining Carnegie he was on the faculty of the University of Michigan.

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 Solar
