Many people have heard of Pangaea, the supercontinent that included all continents on Earth and began to break up about 175 million years ago. But before Pangaea, Earth’s landmasses ripped apart and smashed back together to form supercontinents repeatedly. This cycle has been going on for at least the last 3.0 billion years of Earth’s history, regulating our planet’s geography, climate, and carbon cycles.

Each supercontinent has its quirks, but one, called Rodinia, assembled from 1.3 to 0.9 billion years ago and broken up about 0.75 billion years ago, is particularly odd. A study led by Carnegie's Chao Liu and Robert Hazen (also the Deep Carbon Observatory's executive director),

Postdoctoral researcher at the Department of Terrestrial Magnetism (DTM), Miki Nakajima, has been awarded the eighth Postdoctoral Innovation and Excellence Award (PIE). These prizes are made through nominations from the departments and are chosen by the Office of the President. The recipients are awarded a cash prize for their exceptionally creative approaches to science, strong mentoring, and contributing to the sense of campus community.

Miki is a planetary geophysicist who joined Carnegie in 2015 from the California Institute of Technology, where she received her Ph.D. She uses computational methods to study the formation of planets and their satellites to predict the dynamics

Washington, DC— New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of the star’s seven known planets. If gas giant planets are found in this system’s outer edges, it could help scientists understand how our own Solar System’s gas giants like Jupiter and Saturn formed.

Earlier this year, NASA’s Spitzer Space Telescope thrilled the world as it revealed that TRAPPIST-1, an ultra-cool dwarf star in the Aquarius constellation, was the first-known system of seven Earth-sized planets orbiting a single star. Three of these planets are in the so-called habitable zone—

Washington, DC— According to one longstanding theory, our Solar System’s formation was triggered by a shock wave from an exploding supernova. The shock wave injected material from the exploding star into a neighboring cloud of dust and gas, causing it to collapse in on itself and form the Sun and its surrounding planets.

New work from Carnegie’s Alan Boss offers fresh evidence supporting this theory, modeling the Solar System’s formation beyond the initial cloud collapse and into the intermediate stages of star formation. It is published by The Astrophysical Journal.

One very important constraint for testing theories of Solar System formation is meteorite chemistry.

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 structure,

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,

The WGESP was charged with acting as a focal point for research on extrasolar planets and organizing IAU activities in the field, including reviewing techniques and maintaining a list of identified planets. The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU. The founding president of Commission 53 is Michael Mayor, in honor of

The Anglo-Australian Planet Search (AAPS) is a long-term program being carried out on the 3.9-meter Anglo-Australian Telescope (AAT) to search for giant planets around more than 240 nearby Sun-like stars. The team, including Carnegie scientists,  uses the "Doppler wobble" technique to search for these otherwise invisible extra-solar planets, and achieve the highest long-term precision demonstrated by any Southern Hemisphere planet search.

Alan Boss is a theorist and an observational astronomer. His theoretical work focuses on the formation of binary and multiple stars, triggered collapse of the presolar cloud that eventually made  the Solar System, mixing and transport processes in protoplanetary disks, and the formation of gas giant and ice giant protoplanets. His observational works centers on the Carnegie Astrometric Planet Search project, which has been underway for the last decade at Carnegie's Las Campanas Observatory in Chile.

While fragmentation is universally recognized as the dominant formation mechanism for binary and multiple stars, there are still major questions. The most important of these is the

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 they can tell

Rocks, fossils, and other natural relics hold clues to ancient environments in the form of different ratios of isotopes—atomic variants of elements with the same number of protons but different numbers of neutrons. Seawater, rain water, oxygen, and ozone, for instance, all have different ratios, or fingerprints, of the oxygen isotopes 16O, 17O, and 18O. Weathering, ground water, and direct deposition of atmospheric aerosols change the ratios of the isotopes in a rock revealing a lot about the past climate.

Douglas Rumble’s research is centered on these three stable isotopes of oxygen and the four stable isotopes of sulfur 32S , 33S , 34S, and 36S. In addition to revealing what

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 in
