Carnegie mineralogist Robert Hazen
May 28, 2021

Washington, DC—Carnegie Mineralogist Robert Hazen—who advanced the concept that Earth’s geology was shaped by the rise and sustenance of life—will be honored with the 2022 International Mineralogical Association’s Medal for Excellence. The prize recognizes “outstanding scientific publication in the field of mineralogical sciences.”

The medal was created to honor a lifetime of achievement in and outstanding contributions to the fields of mineralogy, geochemistry, petrology, crystallography, and applied mineralogy.  Hazen will be its 11th recipient.

Washington, DC— The cause of Earth’s deepest earthquakes has been a mystery to science for more than a century, but a team of Carnegie scientists may have cracked the case.

New research published in AGU Advances provides evidence that fluids play a key role in deep-focus earthquakes—which occur between 300 and 700 kilometers below the planet’s surface. The research team includes Carnegie scientists Steven Shirey, Lara Wagner, Peter van Keken, and Michael Walter, as well as the University of Alberta’s Graham Pearson.

Most earthquakes occur close to the Earth’s surface, down to about 70 kilometers.  They happen when stress builds up at

Washington, DC— A team of astronomers including Carnegie’s Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an assistant professor at the University of Colorado Boulder, spotted an extreme outburst, or flare, from the Sun’s nearest neighbor—the star Proxima Centauri.

Their work, which could help guide the search for life beyond our Solar System, is published in The Astrophysical Journal Letters.

Proxima Centauri is a “red dwarf” with about one-eighth the mass of our Sun, which sits just four light-years, or almost 25 trillion miles, from the center of our Solar System and hosts at least two planets, one of which may

Washington, DC— The 2018 eruption of Kīlauea Volcano in Hawai‘i provided scientists with an unprecedented opportunity to identify new factors that could help forecast the hazard potential of future eruptions.

The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could be for nearby communities.

Very viscous magmas are linked with more powerful explosions because they can block gas from escaping through vents, allowing pressure to build up inside the volcano’s plumbing system. On the other hand, extrusion of more viscous

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

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.

Marilyn Fogel’s thirty-three year career at Carnegie’s Geophysical Laboratory (1977-2013), followed

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.

Carnegie was once part of the NASA Astrobiology Institute (NAI).Carnegie Science at Broad Branch Road was one of the  founding members of the 1998 teams who partnered with NASA, and remained a member through several Cooperative Agreement Notices (CANS):  CAN 1  from 1998 - 2003, CAN 3 from 2003 - 2008, and CAN 5 from 2009 - 2015. The Carnegie team focused 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

Scott Sheppard studies the dynamical and physical properties of small bodies in our Solar System, such as asteroids, comets, moons and trans-neptunian objects (bodies that orbit beyond Neptune).  These objects have a fossilized imprint from the formation and migration of the major planets in our Solar System, which allow us to understand how the Solar System came to be.

The major planets in our Solar System travel around the Sun in fairly circular orbits and on similar planes. However, since the discovery of wildly varying planetary systems around other stars, and given our increased understanding about small, primordial bodies in our celestial neighborhood, the notion that

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

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,

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
