Washington, DC— Carnegie scientists Michael Walter and Robert Hazen have been elected 2019 Fellows of the American Geophysical Union.

Fellows are recognized for visionary leadership and scientific excellence that has fundamentally advanced research in the Earth and space sciences. “Their breadth of interests and the scope of their contributions are remarkable and often groundbreaking,” said the organization in its announcement of the new class.  

The Director of Carnegie’s Geophysical Laboratory, Walter is an experimental petrologist whose research focuses on early Earth’s history, shortly after the planet accreted from the cloud of gas

Washington, DC—Some volcanoes take their time—experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when they pose a danger to their surrounding areas, but Carnegie’s Diana Roman and Penn State’s Peter LaFemina are trying to change that.

“Dormancy, brief unrest, eruption—this is a familiar pattern for many volcanoes, and for many parents,” joked Roman. “But for some volcanoes the unrest is anything but brief—potentially lasting for decades.”

It turns out that these so-called “persistently restless volcanoes” experience three different

Pasadena, CA— Sometimes there is more to a planetary system than initially meets the eye. 

Ground-based observations following up on the discovery of a small planet by NASA’s Transiting Exoplanet Survey Satellite (TESS) revealed two additional planets in the same system, one of which is located far enough from its star to be potentially habitable.  These findings were announced in Astronomy & Astrophysics by an international team that included several Carnegie astronomers and instrumentation specialists.

A $2.7 million multi-disciplinary, multi-institutional NSF-Frontiers of Earth Science grant has been awarded to a team led by Carnegie’s Lara Wagner to study an active flat slab in Colombia. A flat slab is produced when a tectonic plate descends to depths of about 30 to 60 miles (~50-100 km) then flattens and travels horizontally for hundreds of miles before descending farther into Earth’s mantle. Flat slabs are unlike standard subduction, in which a tectonic plate descends more steeply beneath another plate directly into the Earth. 

Because flat slabs travel horizontally directly beneath the overriding continents for hundreds of miles, they have more extensive

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.

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

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.

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

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-

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil

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

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
