Washington, DC—New work from an international team of astronomers including Carnegie’s Jaehan Bae used archival radio telescope data to develop a new method for finding very young extrasolar planets. Their technique successfully confirmed the existence of two previously predicted Jupiter-mass planets around the star HD 163296. Their work is published by The Astrophysical Journal Letters.

Of the thousands of exoplanets discovered by astronomers, only a handful are in their formative years. Finding more baby planets will help astronomers answer the many outstanding questions about planet formation, including the process by which our own Solar System came into existence.

Washington, DC— NASA’s Curiosity rover has discovered new “tough” organic molecules in three-billion-year-old sedimentary rocks on Mars, increasing the chances that the record of habitability and potential life could have been preserved on the Red Planet, despite extremely harsh conditions on the surface that can easily break down organic molecules.

“The Martian surface is exposed to radiation from space and harsh chemicals that break down organic matter, so finding ancient organic molecules in the top five centimeters, from a time when Mars may have been habitable, bodes well for us to learn the story of organic molecules on Mars with future missions that will drill deeper,” said

Washington, DC—A team of scientists led by Carnegie’s Shaunna Morrison and including Bob Hazen have revealed the mineralogy of Mars at an unprecedented scale, which will help them understand the planet’s geologic history and habitability. Their findings are published in two American Mineralogist papers.

Minerals form from novel combinations of elements. These combinations can be facilitated by geological activity, including volcanoes and water-rock interactions. Understanding the mineralogy of another planet, such as Mars, allows scientists to backtrack and understand the forces that shaped their formation in that location.

Washington, DC—A team of researchers including Carnegie’s Bob Hazen is using network analysis techniques—made popular through social media applications—to find patterns in Earth’s natural history, as detailed in a paper published by Proceedings of the National Academy of Science. 

By using network analysis to search for communities of marine life in the fossil records of the Paleobiology Database, the team—including researchers at Harvard University and Rensselaer Polytechnic Institute—was able to quantify the ecological impacts of major events like mass extinctions. Their work may help humanity anticipate the consequences of a “sixth mass extinction,” which the rate of species

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

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 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, forging a

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,

Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic processes.

Shirey’s past, current, and future studies reflect the diversity of continental rocks, encompassing a range of studies that include rocks formed anywhere from the deep mantle to the surface crust. His work spans a wide range of geologic settings such as volcanic rocks in continental rifts (giant crustal breaks where continents split apart), ancient and present subduction zones

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

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

Viktor Struzhkin develops new techniques for high-pressure experiments to measure transport and magnetic properties of materials to understand aspects of geophysics, planetary science, and condensed-matter physics. Among his goals are to detect the transition of hydrogen into a high-temperature superconductor under pressure—a state predicted by theory, but thus far unattained—to discover new superconductors, and to learn what happens to materials in Earth’s deep interior where pressure and temperature conditions are extreme. 

Recently, a team including Struzhkin was the first to discover the conditions under which nickel oxide can turn into an electricity-conducting metal. Nickel
