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.

Washington, DC— An international team of astronomers released the largest-ever compilation of exoplanet-detecting observations made using a technique called the radial velocity method. They demonstrated how these observations can be used to hunt for planets by detecting more than 100 potential exoplanets, including one orbiting the fourth-closest star to our own Solar System, which is about 8.1 light years away from Earth. The paper is published in The Astronomical Journal.

The radial velocity method is one of the most successful techniques for finding and confirming planets. It takes advantage of the fact that in addition to a planet being influenced by the gravity of the star it

Yingwei Fei, a high-pressure experimentalist at the Geophysical Laboratory, and Peter Driscoll, theoretical geophysicist in the Department of Terrestrial Magnetism, have been awarded a Carnegie Science Venture Grant for their project “Direct Shock Compression of Pre-synthesized Mantle Mineral to Super-Earth Interior Conditions.”

The project is an entirely new approach to investigate the properties and dynamics of super-Earths—extrasolar planets with masses between one and 10 times that of Earth. They will use the world’s most powerful magnetic, pulsed-power radiation source, called the Z Machine at Sandia National Laboratory, to generate shock waves that can simulate the intense

Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth’s interior. Analysis by Carnegie’s Marion Le Voyer and Erik Hauri of crystals containing completely enclosed mantle magma with its original carbon content preserved has doubled the world’s known finds of mantle carbon. The findings are published in Nature Communications.

Overall, there is a lot about carbon chemistry that takes place below Earth’s crust that scientists still don’t understand. In particular, the amount of carbon in the Earth’s mantle has been the subject of hot debate for decades. This topic is of interest

Washington, DC—New research from a team including Carnegie’s Steven Shirey, Emma Bullock, and Jianhua Wang explains how the world’s biggest and most-valuable diamonds formed—from metallic liquid deep inside Earth’s mantle. The findings are published in Science.

The research team, led by Evan Smith of the Gemological Institute of America, studied large gem diamonds like the world-famous Cullinan or Lesotho Promise by examining their so-called “offcuts,” which are the pieces left over after the gem’s facets are cut for maximum sparkle. They determined that these diamonds sometimes have tiny metallic grains trapped inside them that are made up of a mixture of metallic iron and nickel

The NASA Astrobiology Institute (NAI) Carnegie Team focuses on life’s chemical and physical evolution, from the interstellar medium, through planetary systems, to the emergence and detection of life by studying extrasolar planets, Solar System formation, organic rich primitive planetary bodies, prebiotic molecular synthesis through catalyzing with minerals, and the connection between planetary evolution to the emergence, and sustenance of biology. This program attempts to integrate the sweeping narrative of life’s history through a combination of bottom-up and top-down studies. On the one hand, this team studies processes related to chemical and physical evolution in plausible prebiotic

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.

The WGESP was charged with acting as a focal point for research on extrasolar planets and organizing IAU activities in the field, including reviewing techniques and maintaining a list of identified planets. The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU. The founding president of Commission 53 is Michael Mayor, in honor of

Andrew Steele joins the Rosetta team as a co-investigator working on the COSAC instrument aboard the Philae lander (Fred Goesmann Max Planck Institute - PI). On 12 November 2014 the Philae system will be deployed to land on the comet and begin operations. Before this, several analyses of the comet environment are scheduled from an approximate orbit of 10 km from the comet. The COSAC instrument is a Gas Chromatograph Mass Spectrometer that will measure the abundance of volatile gases and organic carbon compounds in the coma and solid samples of the comet.

Alycia Weinberger wants to understand how planets form, so she observes young stars in our galaxy and their disks, from which planets are born. She also looks for and studies planetary systems.

Studying disks surrounding nearby stars help us determine the necessary conditions for planet formation. Young disks contain the raw materials for building planets and the ultimate architecture of planetary systems depends on how these raw materials are distributed, what the balance of different elements and ices is within the gas and dust, and how fast the disks dissipate.

Weinberger uses a variety of observational techniques and facilities, particularly ultra-high spatial-

Viktor Struzhkin develops new techniques for high-pressure experiments to measure transport and magnetic properties of materials to understand aspects of geophysics, planetary science, and condensed-matter physics. Among his goals are to detect the transition of hydrogen into a high-temperature superconductor under pressure—a state predicted by theory, but thus far unattained—to discover new superconductors, and to learn what happens to materials in Earth’s deep interior where pressure and temperature conditions are extreme. 

Recently, a team including Struzhkin was the first to discover the conditions under which nickel oxide can turn into an electricity-conducting metal. Nickel

Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic processes.

Shirey’s past, current, and future studies reflect the diversity of continental rocks, encompassing a range of studies that include rocks formed anywhere from the deep mantle to the surface crust. His work spans a wide range of geologic settings such as volcanic rocks in continental rifts (giant crustal breaks where continents split apart), ancient and present subduction zones

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 types of
