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.

Washington, DC—Applying big data analysis to mineralogy offers a way to predict minerals missing from those known to science, as well as where to find new deposits, according to a groundbreaking study.

In a paper published by American Mineralogist, scientists report the first application to mineralogy of network theory (best known for analysis of e.g. the spread of disease, terrorist networks, or Facebook connections).

The results, they say, pioneer a potential way to reveal mineral diversity and distribution worldwide, their evolution through deep time, new trends, and new deposits of valuable minerals such as gold or copper.

Several of our geochemistry, cosmochemistry, and astrobiology experts at Carnegie's Department of Terrestrial Magnetism and Geophysical Laboratory study the Moon—how it formed and the source of its water and minerals. For Moon day, we're taking a look back at some of our favorite Carnegie Moon news from the past few years. Take a look! 

Research may solve lunar fire fountain mystery

Tiny beads of volcanic glass found on the lunar surface during the Apollo missions are a sign that fire fountain eruptions took place on the Moon’s surface. Now, scientists from Brown University and the Carnegie Institution for Science have identified the volatile gas that drove those eruptions.   MORE

The NASA Astrobiology Institute (NAI) Carnegie Team focuses 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 minerals, and the connection between planetary evolution to the emergence, and sustenance of biology. This program attempts to integrate the sweeping narrative of life’s history through a combination of bottom-up and top-down studies. On the one hand, this team studies processes related to chemical and physical evolution in plausible prebiotic

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.

The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) mission to orbit Mercury following three flybys of that planet is a scientific investigation of the planet Mercury. Understanding Mercury, and the forces that have shaped it is fundamental to understanding the terrestrial planets and their evolution. This is the first orbital mission around the innermost planet. It took years of planning and complex trajectory to reach Mercury. Carnegie scientists have led the way revealing results that have redefined what we thought we knew about Mercury and the other rocky planets. For more information see http://messenger.jhuapl.edu/

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.

Seismic waves flow through Earth’s solid and liquid material differently, allowing Earth scientists to determine various aspects of the composition of the Earth’s interior. Broadband seismology looks at a broad spectrum of waves for high-resolution imaging. Lara Wagner collects this data from continental areas of the planet that have not been studied before to better understand the elastic properties of Earth’s crust and upper mantle, the rigid region called the lithosphere.

By its nature seismology is indirect research and has limitations for interpreting features like temperature, melting, and exact composition. So Wagner looks at the bigger picture. She integrates her data with

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

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 types of

With the proliferation of discoveries of planets orbiting other stars, the race is on to find habitable worlds akin to the Earth. At present, however, extrasolar planets less massive than Saturn cannot be reliably detected. Astrophysicist John Chambers models the dynamics of these newly found giant planetary systems to understand their formation history and to determine the best way to predict the existence and frequency of smaller Earth-like worlds.

As part of this research, Chambers explores the basic physical, chemical, and dynamical aspects that led to the formation of our own Solar System--an event that is still poorly understood. His ultimate goal is to determine if similar
