Washington, DC—A team of astronomers, including Carnegie’s Scott Sheppard, David Tholen from the University of Hawaiʻi Institute for Astronomy, and Chad Trujillo from Northern Arizona University have discovered discovered the most distant object ever observed in our Solar System.

Officially called 2018 AG37, the object is nicknamed Farfarout for just how far away from the Sun it is orbiting—about 132 AU, where 1 AU is the distance between the Earth and Sun. At that distance, it takes an entire millennium to orbit the Sun.

The three colleagues have been surveying the sky since 2012 to map the Solar System beyond Pluto. FarFarOut joins a set of these

Washington, DC— New research led by Carnegie’s Yingwei Fei provides a framework for understanding the interiors of super-Earths—rocky exoplanets between 1.5 and 2 times the size of our home planet—which is a prerequisite to assess their potential for habitability.  Planets of this size are among the most abundant in exoplanetary systems.  The paper is published in Nature Communications.

“Although observations of an exoplanet’s atmospheric composition will be the first way to search for signatures of life beyond Earth, many aspects of a planet’s surface habitability are influenced by what’s happening beneath the planet

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

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.

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

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,

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil

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

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

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.
