Washington, DC— What does a gestating baby planet look like? New research in Nature by a team including Carnegie’s Jaehan Bae investigated the effects of three planets in the process of forming around a young star, revealing the source of their atmospheres.

In their youth, stars are surrounded by a rotating disk of gas and dust from which planets are born. Studying the behavior of the material that makes up these disks can reveal new details about planet formation, and about the evolution of a planetary system as a whole.

The disk around a young star called HD 163296 is known to include several rings and gaps. Using 3-D visualizations taken by the Atacama Large

Washington, DC—Move over Jupiter; Saturn is the new moon king.

A team led by Carnegie's Scott S. Sheppard has found 20 new moons orbiting Saturn.  This brings the ringed planet’s total number of moons to 82, surpassing Jupiter, which has 79. The discovery was announced Monday by the International Astronomical Union’s Minor Planet Center.

Each of the newly discovered moons is about five kilometers, or three miles, in diameter. Seventeen of them orbit the planet backwards, or in a retrograde direction, meaning their movement is opposite of the planet's rotation around its axis. The other three moons orbit in the prograde—the same direction

Washington, DC—There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA’s WFIRST space telescope, according to new models of gas giant planet formation by Carnegie’s Alan Boss described in an upcoming publication in The Astrophysical Journal.  His models are supported by a new Science paper on the surprising discovery of a gas giant planet orbiting a low-mass star.

“Astronomers have struck a bonanza in searching for and detecting exoplanets of every size and stripe since the first confirmed exoplanet, a hot Jupiter, was discovered in 1995,” Boss explained.

Washington, DC—Carnegie’s Scott Sheppard and his long-time colleague Chad Trujillo of Northern Arizona University received The Europlanet Society’s 2019 Paolo Farinella Prize for “outstanding collaborative work for the observational characterization of the Kuiper belt and the Neptune-trojan population.” 

The prize was established in 2010 in honor of Italian scientist whose name it bears and the winners must be excellent investigators who are no older than 47, which was Farinella’s age when he died, and who have achieved important results in one of his research areas. Each year the Prize focuses on a different one of these topics and in 2019

Carnegie was once part of the NASA Astrobiology Institute (NAI).Carnegie Science at Broad Branch Road was one of the  founding members of the 1998 teams who partnered with NASA, and remained a member through several Cooperative Agreement Notices (CANS):  CAN 1  from 1998 - 2003, CAN 3 from 2003 - 2008, and CAN 5 from 2009 - 2015. The Carnegie team focused 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

Superdeep diamonds are  tiny time capsules carrying unchanged impurities made eons ago and providing researchers with important clues about Earth’s formation.  Diamonds derived from below the continental lithosphere, are most likely from the transition zone (415 miles, or 670km deep) or the top of the lower mantle. Understanding diamond origins and compositions of the high-pressure mineral phases has potential to revolutionize our understanding of deep mantle circulation.


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

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,

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

Geochemist and director of Terrestrial Magnetism, Richard Carlson, looks at the diversity of the chemistry of the early solar nebula and the incorporation of that chemistry into the terrestrial planets. He is also interested in questions related to the origin and evolution of Earth’s continental crust.

  Most all of the chemical diversity in the universe comes from the nuclear reactions inside stars, in a process called nucleosynthesis. To answer his questions, Carlson developes novel procedures using instruments called mass spectrometers to make precise measurements of isotopes--atoms of an element with different numbers of neutrons--of Chromium (Cr), strontium (Sr),

Volcanologist Diana Roman is interested in the mechanics of how magma moves through the Earth’s crust, and in the structure, evolution, and dynamics of volcanic conduit systems. Her ultimate goal is to understand the likelihood and timing of volcanic eruptions.

Most of Roman’s research focuses on understanding changes in seismicity and stress in response to the migration of magma through volcanic conduits, and on developing techniques and strategies for monitoring active or restless volcanoes through the analysis of high-frequency volcanic seismicity.

Roman is also interested in understanding the seismicity at quiet volcanoes, tectonic and hidden volcanic

Peter van Keken studies the thermal and chemical evolution of the Earth. In particularly he looks at the causes and consequences of plate tectonics; element modeling of mantle convection,  and the dynamics of subduction zones--locations where one tectonic plate slides under another. He also studies mantle plumes; the integration of geodynamics with seismology; geochemistry and mineral physics. He uses parallel computing and scientific visualization in this work.

He received his BS and Ph D from the University of Utrecht in The Netherlands. Prior to joining Carnegie he was on the faculty of the University of Michigan.
