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

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

CALL FOR PROPOSALS

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

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.

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.

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.

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.

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),

What sets George Cody apart from other geochemists is his pioneering use of sophisticated techniques such as enormous facilities for synchrotron radiation, and sample analysis with nuclear magnetic resonance (NMR) spectroscopy to characterize hydrocarbons. Today, Cody  applies these techniques to analyzing the organic processes that alter sediments as they mature into rock inside the Earth and the molecular structure of extraterrestrial organics.

Wondering about where we came from has occupied the human imagination since the dawn of consciousness. Using samples from comets and meteorites, George Cody tracks the element carbon as it moves from the interstellar medium, through
