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.

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

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.

The WGESP was charged with acting as a focal point for research on extrasolar planets and organizing IAU activities in the field, including reviewing techniques and maintaining a list of identified planets. The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU. The founding president of Commission 53 is Michael Mayor, in honor of

Starting in 2005, the High Lava Plains project is focused on a better understanding of why the Pacific Northwest, specifically eastern Oregon's High Lava Plains, is so volcanically active. This region is the most volcanically active area of the continental United States and it's relatively young. None of the accepted paradigms explain why the magmatic and tectonic activity extend so far east of the North American plate margin. By applying numerous techniques ranging from geochemistry and petrology to active and passive seismic imaging to geodynamic modeling, the researchers examine an assemblage of new data that will provide key information about the roles of lithosphere

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.

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

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
