Washington, DC—It’s amazing what a difference a little water can make.
The Moon formed between about 4.4 and 4.5 billion years ago when an object collided with the still-forming proto-...
Washington, DC— Brown dwarfs, the larger cousins of giant planets, undergo atmospheric changes from cloudy to cloudless as they age and cool. A team of astronomers led by Carnegie’s...
Washington, DC— Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than...
Many people have heard of Pangaea, the supercontinent that included all continents on Earth and began to break up about 175 million years ago. But before Pangaea, Earth’s landmasses ripped...
Postdoctoral researcher at the Department of Terrestrial Magnetism (DTM), Miki Nakajima, has been awarded the eighth Postdoctoral Innovation and Excellence Award (PIE). These prizes are made through...
Washington, DC— New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of...
Washington, DC— According to one longstanding theory, our Solar System’s formation was triggered by a shock wave from an exploding supernova. The shock wave injected material from the...
Washington, DC—Applying big data analysis to mineralogy offers a way to predict minerals missing from those known to science, as well as where to find new deposits, according to a...

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...
The Anglo-Australian Planet Search (AAPS) is a long-term program being carried out on the 3.9-meter Anglo-Australian Telescope (AAT) to search for giant planets around more than 240 nearby Sun-like stars. The team, including Carnegie scientists, uses the "Doppler wobble" technique...
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...
Andrew Steele uses traditional and biotechnological approaches for the detection of microbial life in the field of astrobiology and Solar System exploration. Astrobiology is the search for the origin and distribution of life in the universe. A microbiologist by training, his principle interest is...
Some 40 thousand tons of extraterrestrial material fall on Earth every year. This cosmic debris provides cosmochemist Conel Alexander with information about the formation of the Solar System, our galaxy, and perhaps the origin of life.
Alexander studies meteorites to determine what went on before...
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...
