Washington, DC— Carnegie astronomers Stephen Shectman and Alycia Weinberger were selected for the inaugural class of Fellows of the American Astronomical Society in recognition of their “extraordinary achievement and service” to the field. 

The newly established accolade will honor members of the organization for original research, innovative technique and instrumentation development, significant public outreach and educational efforts, and other noteworthy contributions to the society. To launch the program, the AAS selected 200 “legacy” fellows, including Shectman and Weinberger. Carnegie trustee Sandra Faber of UC Santa Cruz and former-

Washington, DC— A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska’s Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes. The findings are published in Scientific Reports by Helen Janiszewski, recently of Carnegie, now at the University of Hawaiʻi at Mānoa, and Carnegie’s Lara Wagner and Diana Roman. 

Arc volcanoes like Cleveland form over plate boundaries where one tectonic plate slides beneath another. They are linked to the Earth’s mantle by complex subsurface structures that cross the full thickness of the planet's crust. These

Washington, D.C.— Carnegie trustee emeritus Frank Press, a National Medal of Science laureate and former president of the National Academy of Sciences, died January 29 at his home in Chapel Hill, N.C. He was 95. Press was active on the Carnegie board of trustees for 14 years and was the Cecil and Ida Green Senior Fellow at the institution’s Department of Terrestrial Magnetism from 1993 to 1997.

A distinguished geophysicist whose contributions to plate tectonics revolutionized the field, Press authored more than 150 papers and co-authored two foundational Earth science textbooks. He also made tremendous contributions to science policy and helped shape the U.S.

Carnegie Earth and Planets Director Richard Carlson

Washington, DC — Richard Carlson, director of Carnegie’s Earth and Planets division, has been chosen to receive the Geochemical Society’s highest honor, the Victor Moritz Goldschmidt Award, in recognition of his forefront research into the formation of the Solar System and the geologic history of the Earth, the society announced Tuesday.

The society will present the award to Carlson at the Goldschmidt Conference, to be held in Honolulu in June.

“I am deeply honored to receive the V.M. Goldschmidt Award, which recognizes our efforts to understand the origin and evolution of Earth’s continental crust on Earth and the consequences of its formation

The Anglo-Australian Planet Search (AAPS) is a long-term program being carried out on the 3.9-meter Anglo-Australian Telescope (AAT) to search for giant planets around more than 240 nearby Sun-like stars. The team, including Carnegie scientists,  uses the "Doppler wobble" technique to search for these otherwise invisible extra-solar planets, and achieve the highest long-term precision demonstrated by any Southern Hemisphere planet search.

CALL FOR PROPOSALS

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

Carnegie scientists participate in NASA's Kepler missions, the first mission capable of finding Earth-size planets around other stars. The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement and popular interest surrounding the discovery of hundreds of planets orbiting other stars. There is now clear evidence for substantial numbers of three types of exoplanets; gas giants, hot-super-Earths in short period orbits, and ice giants.

The challenge now is to find terrestrial planets (those one half to twice the size of the Earth), especially those in the habitable zone of their stars where liquid water and possibly life might exist.

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

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

Geochemist and director of Terrestrial Magnetism, Richard Carlson, looks at the diversity of the chemistry of the early solar nebula and the incorporation of that chemistry into the terrestrial planets. He is also interested in questions related to the origin and evolution of Earth’s continental crust.

  Most all of the chemical diversity in the universe comes from the nuclear reactions inside stars, in a process called nucleosynthesis. To answer his questions, Carlson developes novel procedures using instruments called mass spectrometers to make precise measurements of isotopes--atoms of an element with different numbers of neutrons--of Chromium (Cr), strontium (Sr),

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.

With the proliferation of discoveries of planets orbiting other stars, the race is on to find habitable worlds akin to the Earth. At present, however, extrasolar planets less massive than Saturn cannot be reliably detected. Astrophysicist John Chambers models the dynamics of these newly found giant planetary systems to understand their formation history and to determine the best way to predict the existence and frequency of smaller Earth-like worlds.

As part of this research, Chambers explores the basic physical, chemical, and dynamical aspects that led to the formation of our own Solar System--an event that is still poorly understood. His ultimate goal is to determine if similar
