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 census. They will then be able to tell what percentage of stars have planets, how many systems are similar to our own, and the different characteristics these systems exhibit. The ultimate goal is to find planets that resemble the Earth. Image courtesy NASA

Erik Hauri, who found water on the Moon, dies at 52
September 6, 2018

Washington, DC—Carnegie geochemist Erik Hauri, whose work upended our understanding of the Moon’s formation and the importance of water in Earth’s interior, died Wednesday in North Potomac, MD, following a battle with cancer. He was 52.

Hauri joined Carnegie as a staff scientist in 1994 and spent nearly 25 years investigating the geochemistry of the Earth, Moon, and other celestial objects.  Hauri had a particular interest in water, which he called the most-important molecule in our Solar System, saying that understanding where it came from and how it got distributed among the planets and various other bodies would unlock the secrets of how our Solar System evolved.

Stellar “swarms” help astronomers understand the evolution of stars
August 28, 2018

Washington, DC—New work from Carnegie’s Jonathan Gagné and the American Museum of Natural History’s Jacqueline Faherty identified nearly a thousand potential members and 31 confirmed members of stellar associations—stars of similar ages and compositions that are drifting together through space—in our own corner of the Milky Way. Their research, published in The Astrophysical Journal, could help astronomers understand the evolution of stars and the properties of future exoplanet discoveries.

“Like a swarm of birds flying together in the sky, the common velocities of stars in an association tell us that us that they are related,” Gagné explained. “This teaches us something about

Bernard Burke, who co-discovered Jupiter’s “voice,” dies at 90
August 10, 2018

Bernard Burke, distinguished MIT astrophysicist and former staff scientist at Carnegie's Department of Terrestrial Magnetism, died August 5. He was 90. 

Burke, who joined the department's in 1953, was an integral member of its astronomy group until he left to be professor of physics at MIT in 1965, where his work shifted to, among other things, the detection of gravitational lensing. He also played a key role in the development of Very Long Baseline Interferometry (VLBI), which enables high-resolution imaging of cosmic structures. He was elected to the National Academy of Sciences in 1970 and served as president of the American Astronomical Society from 1986 to 1988. He was an

What makes diamonds blue? Boron from oceanic crustal remnants in Earth’s lower mantle
July 31, 2018

Washington, DC—Blue diamonds—like the world-famous Hope Diamond at the National Museum of Natural History—formed up to four times deeper in the Earth’s mantle than most other diamonds, according to new work published on the cover of Nature.

“These so-called type IIb diamonds are tremendously valuable, making them hard to get access to for scientific research purposes,” explained lead author Evan Smith of the Gemological Institute of America, adding, “and it is very rare to find one that contains inclusions, which are tiny mineral crystals trapped inside the diamond.”

Inclusions are remnants of the minerals from the rock in which the diamond crystallized and can tell

Marilyn Fogel Endowed Fund for Internships

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 by four years at the University of California,

Carnegie Science Venture Grants

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 years,

Rosetta Mission

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.

The Deep Carbon Observatory

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 disciplinary lines,

William Ludington

The Ludington lab investigates complex ecological dynamics from microbial community interactions using the fruit fly  Drosophila melanogaster. The fruit fly gut carries numerous microbial species, which can be cultured in the lab. The goal is to understand the gut ecology and how it relates to host health, among other questions, by taking advantage of the fast time-scale and ease of studying the fruit fly in controlled experiments.

Michael Walter, Director

Experimental petrologist Michael Walter became director of the Geophysical Laboratory beginning April 1, 2018. His recent research has focused on the period early in Earth’s history, shortly after the planet accreted from the cloud of gas and dust surrounding our young Sun, when the mantle and the core first separated into distinct layers. Current topics of investigation also include the structure and properties of various compounds under the extreme pressures and temperatures found deep inside the planet, and information about the pressure, temperature, and chemical conditions of the mantle that can be gleaned from mineral impurities preserved inside diamonds.
