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

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.

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.

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

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

Volcanologist Diana Roman is interested in the mechanics of how magma moves through the Earth’s crust, and in the structure, evolution, and dynamics of volcanic conduit systems. Her ultimate goal is to understand the likelihood and timing of volcanic eruptions.

Most of Roman’s research focuses on understanding changes in seismicity and stress in response to the migration of magma through volcanic conduits, and on developing techniques and strategies for monitoring active or restless volcanoes through the analysis of high-frequency volcanic seismicity.

Roman is also interested in understanding the seismicity at quiet volcanoes, tectonic and hidden volcanic

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

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

Earth scientist Robert Hazen has an unusually rich research portfolio. He is trying to understand the carbon cycle from deep inside the Earth; chemical interactions at crystal-water interfaces; the interactions of organic molecules on mineral surfaces as a possible springboard to life; how life arose from the chemical to the biological world; how life emerges in extreme environments; and the origin and distribution of life in the universe  just to name a few topics. In tandem with this expansive Carnegie work, he is also the Clarence Robinson Professor of Earth Science at George Mason University. He has authored more than 350 articles and 20 books on science, history, and music.
