Washington, D.C.—On March 17, the tiny MESSENGER spacecraft completed its primary mission to orbit and observe the planet Mercury for one Earth-year. The bounty of surprises from the mission has...
Washington, D.C.— Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at...
Washington, D.C.— An international team of scientists led by Carnegie’s Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a...
Washington, D.C. — Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth’s...

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 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 -...
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...
Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjø...
Scott Sheppard studies the dynamical and physical properties of small bodies in our Solar System, such as asteroids, comets, moons and trans-neptunian objects (bodies that orbit beyond Neptune). These objects have a fossilized imprint from the formation and migration of the major planets in...
With the proliferation of discoveries of planets orbiting other stars, the race is on to find habitable worlds akin to the Earth. At present, however, extrasolar planets less massive than Saturn cannot be reliably detected. Astrophysicist John Chambers models the dynamics of these newly found giant...
