Washington, DC— A diamond lasts forever, but that doesn’t mean all diamonds have a common history. 

Some diamonds were formed billions of years ago in space as the carbon-rich atmospheres of dying stars expanded and cooled. In our own planet’s lifetime, high-temperatures and pressures in the mantle produced the diamonds that are familiar to us as gems. 5,000 years ago, a large meteorite that struck a carbon-rich sediment on Earth produced an impact diamond.

Each of these diamonds differs from the others in both composition and genesis, but all are categorized as “diamond” by the authoritative guide to minerals—the International

Washington, DC— A small group of volcanic islands in Alaska's Aleutian chain could actually be part of a single, previously unrecognized giant volcano in the same category as Yellowstone, according to work from a research team, including Carnegie’s Diana Roman, Lara Wagner, Hélène Le Mével, and Daniel Portner, as well as recently departed postdoc Helen Janiszewski (now at University of Hawaiʻi at Mānoa), who will present their findings at the American Geophysical Union’s Fall Meeting next week.

The Islands of the Four Mountains in the central Aleutians is a tight group of six volcanos: Carlisle, Cleveland, Herbert, Kagamil, Tana and

Washington, DC— Richard Carlson, Director of Carnegie’s Earth and Planets Laboratory, has been named a Fellow of the American Association for the Advancement of Science. He was selected for his “outstanding research, leadership, innovation, and service to the community in geochemistry and geology.”

The tradition of AAAS Fellows began in 1874 and election for this honor is bestowed upon AAAS members by their peers. This year 489 members have been selected due to their “scientifically or socially distinguished efforts to advance science or its applications.” 

A Carnegie staff member since 1981, Carlson is widely recognized for his use

Washington, DC—New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System’s unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter.

In its youth, our Sun was surrounded by a rotating disk of gas and dust from which the planets were born.  The orbits of early formed planets were thought to be initially close-packed and circular, but gravitational interactions between the larger objects perturbed the arrangement and

Join us to learn about exoplanet science from Johanna Teske, a former Carnegie postdoc who joined our Earth and Planets Laboratory as a Staff Scientist last September. This is the first virtual program in our winter series of online conversations with several of our exciting investigators.  

Teske’s work aims to help scientists better understand the planetary formation process and explain why there is such tremendous planetary diversity in our galaxy. She uses observational data from the telescopes at Carnegie’s Las Campanas Observatory, as well as from space-based telescopes and other facilities, to estimate the interior and atmospheric

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

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

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.

Peter Driscoll studies the evolution of Earth’s core and magnetic field including magnetic pole reversal. Over the last 20 million or so years, the north and south magnetic poles on Earth have reversed about every 200,000, to 300,000 years and is now long overdue. He also investigates the Earth’s inner core structure; core-mantle coupling; tectonic-volatile cycling; orbital migration—how Earth’s orbit moves—and tidal dissipation—the dissipation of tidal forces between two closely orbiting bodies. He is also interested in planetary interiors, dynamos, upper planetary atmospheres and exoplanets—planets orbiting other stars. He uses large-

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

Cosmochemist Larry Nittler studies extraterrestrial materials, including meteorites and interplanetary dust particles (IDPs), to understand the formation of the Solar System, the galaxy, and the universe and to identify the materials involved. He is particularly interested in developing new techniques to analyze different variants of the same atom—isotopes—in small samples. In related studies, he uses space-based X-ray and gamma-ray instrumentation to determine the composition of planetary surfaces. He was part of the 2000-2001 scientific team to hunt for meteorites in Antarctica.

Nittler is especially interested in presolar grains contained in meteorites and in what

While the planets in our Solar System are astonishingly diverse, all of them move around the Sun in approximately the same orbital plane, in the same direction, and primarily in circular orbits. Over the past 25 years Butler's work has focused on improving the measurement precision of stellar Doppler velocities, from 300 meters per second in the 1980s to 1 meter a second in the 2010s to detect planets around other stars. The ultimate goal is to find planets that resemble the Earth.

Butler designed and built the iodine absorption cell system at Lick Observatory, which resulted in the discovery of 5 of the first 6 known extrasolar planets.  This instrument has become the de
