Washington, DC— Planet-hunting is an ongoing process that’s resulting in the discovery of more and more planets orbiting distant stars. But as the hunters learn more about the variety...
Washington, DC—A team of astronomers from Carnegie and Western University in Ontario, Canada, has discovered one of the youngest and brightest free-floating, planet-like objects within...
Washington, D.C.—Scientists have long been puzzled about what makes Mercury’s surface so dark. The innermost planet reflects much less sunlight than the Moon, a body on which surface...
Washington, DC— A team of scientists including Carnegie’s Dina Bower and Andrew Steele weigh in on whether microstructures found in 3.46 billion-year-old samples of a silica-rich rock...
"What is most astonishing about rare minerals is that the processes that ultimately forms most of them comes from biology," Bob Hazen tells the Los Angeles Times. "As life changes...
The world’s 2500 rarest minerals have now been categorised for the first time, revealing intriguing implications. Most have been formed in processes directly or indirectly related to living...

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...
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...
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...
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...
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...
