Washington, DC— A team of astronomers has discovered the most-distant body ever observed in our Solar System.  It is the first known Solar System object that has been detected at a distance that is more than 100 times farther than Earth is from the Sun.

The new object was announced on Monday, December 17, 2018, by the International Astronomical Union’s Minor Planet Center and has been given the provisional designation 2018 VG18. The discovery was made by Carnegie’s Scott S. Sheppard, the University of Hawaii’s David Tholen, and Northern Arizona University’s Chad Trujillo.

Washington, DC—An international team including five Carnegie astronomers has discovered a frozen Super-Earth orbiting Barnard’s star, the closest single star to our own Sun. The Planet Finder Spectrograph on Carnegie’s Magellan II telescope was integral to the discovery, which is published in Nature.

Just six light-years from Earth, Barnard’s star is our fourth-closest neighboring star overall, after Alpha Centauri’s triple-star system. It is smaller and older than our Sun and among the least-active known red dwarfs.

To find this cold Super-Earth, the team—which included Carnegie’s Paul Butler, Johanna Teske, Jeff Crane, Steve

Washington, DC—Mars’ organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to new analyses of three Martian meteorites from a team led by Carnegie’s Andrew Steele published in Science Advances.

The group’s analysis of a trio of Martian meteorites that fell to Earth—Tissint, Nakhla, and NWA 1950—showed that they contain an inventory of organic carbon that is remarkably consistent with the organic carbon compounds detected by the Mars Science Laboratory’s rover missions.

In 2012, Steele led a team that determined the organic carbon found in 10 Martian

Washington, DC—NASA should incorporate astrobiology into all stages of future exploratory missions, according to a new report from the National Academies of Sciences, Engineering, and Medicine presented Wednesday by the chair of the study, University of Toronto’s Barbara Sherwood Lollar, and by Carnegie’s Alan Boss, one of the report’s 17 expert authors.

Astrobiology addresses the factors that allowed life to originate and develop in the universe and investigates whether life exists on planets other than Earth. This highly interdisciplinary and constantly adapting field incorporates expertise in biology, chemistry, geology, planetary science, and physics.

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.

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 (DCO) 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

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.

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

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

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

Scott Sheppard studies the dynamical and physical properties of small bodies in our Solar System, such as asteroids, comets, moons and trans-neptunian objects (bodies that orbit beyond Neptune).  These objects have a fossilized imprint from the formation and migration of the major planets in our Solar System, which allow us to understand how the Solar System came to be.

The major planets in our Solar System travel around the Sun in fairly circular orbits and on similar planes. However, since the discovery of wildly varying planetary systems around other stars, and given our increased understanding about small, primordial bodies in our celestial neighborhood, the notion that
