Washington, DC—Carnegie’s Scott Sheppard and his long-time colleague Chad Trujillo of Northern Arizona University received The Europlanet Society’s 2019 Paolo Farinella Prize for “outstanding collaborative work for the observational characterization of the Kuiper belt and the Neptune-trojan population.” 

The prize was established in 2010 in honor of Italian scientist whose name it bears and the winners must be excellent investigators who are no older than 47, which was Farinella’s age when he died, and who have achieved important results in one of his research areas. Each year the Prize focuses on a different one of these topics and in 2019

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.

The newly found exoplanets orbit a star named GJ 357, an M-type dwarf that’s about one-third of the Sun’s mass and located 31

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,

Superdeep diamonds are  tiny time capsules carrying unchanged impurities made eons ago and providing researchers with important clues about Earth’s formation.  Diamonds derived from below the continental lithosphere, are most likely from the transition zone (415 miles, or 670km deep) or the top of the lower mantle. Understanding diamond origins and compositions of the high-pressure mineral phases has potential to revolutionize our understanding of deep mantle circulation.

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.

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

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-

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

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,
