Earth & Planetary Science Stories
Washington, D.C.— Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven...
Washington, D.C.—A team of scientists, including Carnegie’s Alan Boss, has discovered two Earth-like planets in the habitable orbit of a Sun-like star. Their work is published in Science Express.

Washington, D.C.—New theoretical modeling by Carnegie’s Alan Boss provides clues to how the gas giant planets in our solar system—Jupiter and Saturn—might have formed and evolved. His work was...
Washington, D.C.— Mineral evolution is a new way to look at our planet’s history. It’s the study of the increasing diversity and characteristics of Earth’s near-surface minerals, from the dozen that...
Washington, D.C.— Researchers still have much to learn about the volcanism that shaped our planet’s early history. New evidence from a team led by Carnegie’s Frances Jenner demonstrates that some of...
Washington, D.C.—After extensive analyses by a team of scientists led by Carl Agee at the University of New Mexico, researchers have identified a new class of Martian meteorite that likely originated...
Washington, D.C.— An international team of scientists, including Carnegie’s Paul Butler, has discovered that Tau Ceti, one of the closest and most Sun-like stars, may have five planets. Their work is...
Washington, D.C. — Oceanic crust covers two-thirds of the Earth’s solid surface, but scientists still don’t entirely understand the process by which it is made. Analysis of more than 600 samples of...

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...
Carnegie's Paul Butler has been leading work on a multiyear project to carry out the first reconnaissance of all 2,000 nearby Sun-like stars within 150 light-years of the solar system (1 lightyear is about 9.4 trillion kilometers). His team is currently monitoring about 1,700 stars, including 1...
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 -...
Alan Boss is a theorist and an observational astronomer. His theoretical work focuses on the formation of binary and multiple stars, triggered collapse of the presolar cloud that eventually made the Solar System, mixing and transport processes in protoplanetary disks, and the formation of gas...
Alan Linde is trying to understand the tectonic activity that is associated with earthquakes and volcanos, with the hope of helping predictions methods. He uses highly sensitive data that measures how the Earth is changing below the surface with devises called borehole strainmeters that...
Peter Driscoll studies the evolution of Earth’s core and magnetic field including magnetic pole reversal. Over the last 20 million or so years, the north and south magnetic poles on Earth have reversed about every 200,000, to 300,000 years and is now long overdue. He also investigates...

Washington, D.C.— In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are...
Washington, D.C. — Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the...
Carnegie geochemist Erik Hauri, whose work upended our understanding of the Moon’s formation and the importance of water in Earth’s interior, died Wednesday in North Potomac, MD,...
