Washington, DC— The discovery that our galaxy is teeming with exoplanets has also revealed the vast diversity of planetary systems out there and raised questions about the processes that shaped them. New work published in Science by an international team including Carnegie’s Jaehan Bae could explain the architecture of multi-star systems in which planets are separated by wide gaps and do not orbit on the same plane as their host star’s equatorial center.

“In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline—sometimes a very steep one,”

Washington, DC— The composition of Earth’s mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie’s Jonathan Tucker and Peter van Keken along with colleagues from Oxford that was recently published in Geochemistry, Geophysics, Geosystems.

During its evolution, our planet separated into distinct layers—core, mantle, and crust. Each has its own composition and the dynamic processes through which these layers interact with their neighbors can teach us about Earth’s geologic history.

Plate tectonic processes allow for continuous evolution of the crust and play a key role in our planet

Washington, DC— When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions found deep inside the planet?

New work led by Carnegie’s Sally June Tracy examined the crystal structure of the silica mineral quartz under shock compression and is challenging longstanding assumptions about how this ubiquitous material behaves under such intense conditions. The results are published in Science Advances.

Carnegie's Paul Butler has been leading work on a multiyear project to carry out the first reconnaissance of all 2,000 nearby Sun-like stars within 150 light-years of the solar system (1 lightyear is about 9.4 trillion kilometers). His team is currently monitoring about 1,700 stars, including 1,000 Northern Hemisphere stars with the Keck telescope in Hawaii and the UCO Lick Observatory telescope in California, and 300 Southern Hemisphere stars with the Anglo-Australian telescope in New South Wales, Australia. The remaining Southern Hemisphere stars are being surveyed with Carnegie's new Magellan telescopes in Chile. By 2010 the researchers hope to have completed their planetary

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 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

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

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

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

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

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
