Washington, DC— A diamond lasts forever, but that doesn’t mean all diamonds have a common history. 

Some diamonds were formed billions of years ago in space as the carbon-rich atmospheres of dying stars expanded and cooled. In our own planet’s lifetime, high-temperatures and pressures in the mantle produced the diamonds that are familiar to us as gems. 5,000 years ago, a large meteorite that struck a carbon-rich sediment on Earth produced an impact diamond.

Each of these diamonds differs from the others in both composition and genesis, but all are categorized as “diamond” by the authoritative guide to minerals—the International

Washington, DC— A small group of volcanic islands in Alaska's Aleutian chain could actually be part of a single, previously unrecognized giant volcano in the same category as Yellowstone, according to work from a research team, including Carnegie’s Diana Roman, Lara Wagner, Hélène Le Mével, and Daniel Portner, as well as recently departed postdoc Helen Janiszewski (now at University of Hawaiʻi at Mānoa), who will present their findings at the American Geophysical Union’s Fall Meeting next week.

The Islands of the Four Mountains in the central Aleutians is a tight group of six volcanos: Carlisle, Cleveland, Herbert, Kagamil, Tana and

Washington, DC— Richard Carlson, Director of Carnegie’s Earth and Planets Laboratory, has been named a Fellow of the American Association for the Advancement of Science. He was selected for his “outstanding research, leadership, innovation, and service to the community in geochemistry and geology.”

The tradition of AAAS Fellows began in 1874 and election for this honor is bestowed upon AAAS members by their peers. This year 489 members have been selected due to their “scientifically or socially distinguished efforts to advance science or its applications.” 

A Carnegie staff member since 1981, Carlson is widely recognized for his use

Washington, DC—New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System’s unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter.

In its youth, our Sun was surrounded by a rotating disk of gas and dust from which the planets were born.  The orbits of early formed planets were thought to be initially close-packed and circular, but gravitational interactions between the larger objects perturbed the arrangement and

Join us to learn about exoplanet science from Johanna Teske, a former Carnegie postdoc who joined our Earth and Planets Laboratory as a Staff Scientist last September. This is the first virtual program in our winter series of online conversations with several of our exciting investigators.  

Teske’s work aims to help scientists better understand the planetary formation process and explain why there is such tremendous planetary diversity in our galaxy. She uses observational data from the telescopes at Carnegie’s Las Campanas Observatory, as well as from space-based telescopes and other facilities, to estimate the interior and atmospheric

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.

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

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

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.

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.

Andrew Steele uses traditional and biotechnological approaches for the detection of microbial life in the field of astrobiology and Solar System exploration. Astrobiology is the search for the origin and distribution of life in the universe. A microbiologist by training, his principle interest is in developing protocols, instrumentation, and procedures for life detection in samples from the early Earth and elsewhere in the Solar System.

Steele has developed several instrument and mission concepts for future Mars missions and became involved in the 2011 Mars Science Laboratory mission as a member of the Sample Analysis at Mars (SAM) team. For  a number of years he journeyed to

Scientists simulate the high pressures and temperatures of planetary interiors to measure their physical properties. Yingwei Fei studies the composition and structure of planetary interiors with high-pressure instrumentation including the multianvil apparatus, the piston cylinder, and the diamond anvil cell. 

The Earth was formed through energetic and dynamic processes. Giant impacts, radioactive elements, and gravitational energy heated the  planet in its early stage, melting materials and paving the way for the silicate mantle and metallic core to separate.  As the planet cooled and solidified geochemical and geophysical “fingerprints” resulted from

Alan Linde is trying to understand the tectonic activity that is associated with earthquakes and volcanos, with the hope of helping predictions methods.  He uses highly sensitive data that measures how the Earth is changing below the surface with devises called borehole strainmeters that measure tiny strains the Earth undergoes.

Strainmeter data has led to the discovery of events referred to as slow earthquakes that are similar to regular earthquakes except that the fault motions take place over much longer time scales. These were first detected in south-east Japan and have since been seen in a number of different environments including the San Andreas Fault in California and
