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

Washington, DC— Carnegie scientists Michael Walter and Robert Hazen have been elected 2019 Fellows of the American Geophysical Union.

Fellows are recognized for visionary leadership and scientific excellence that has fundamentally advanced research in the Earth and space sciences. “Their breadth of interests and the scope of their contributions are remarkable and often groundbreaking,” said the organization in its announcement of the new class.  

The Director of Carnegie’s Geophysical Laboratory, Walter is an experimental petrologist whose research focuses on early Earth’s history, shortly after the planet accreted from the cloud of gas

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

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

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

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.

Hélène Le Mével studies volcanoes. Her research focuses on understanding the surface signals that ground deformations make to infer the ongoing process of the moving magma  in the underlying reservoir. Toward this end she uses space and field-based geodesy--the mathematics of the area and shape of the Earth--to identify, model and interpret this ground deformation.

She uses data from radar called Interferometric Synthetic Aperture Radar (InSAR), and data from the Global Positioning System (GPS) to characterize ground motion during volcanic unrest. She also collects gravity data, which indicate changes in mass and/or density underground. These data sets,

Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic processes.

Shirey’s past, current, and future studies reflect the diversity of continental rocks, encompassing a range of studies that include rocks formed anywhere from the deep mantle to the surface crust. His work spans a wide range of geologic settings such as volcanic rocks in continental rifts (giant crustal breaks where continents split apart), ancient and

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.
