Washington, DC— The 2018 eruption of Kīlauea Volcano in Hawai‘i provided scientists with an unprecedented opportunity to identify new factors that could help forecast the hazard potential...
Washington, DC— Diamonds that formed deep in the Earth’s mantle contain evidence of chemical reactions that occurred on the seafloor. Probing these gems can help geoscientists understand...
Washington, DC— Carnegie’s Yingwei Fei is the namesake of an iron-titanuim oxide mineral discovered in a meteorite that originated on Mars. Caltech’s Chi Ma announced the find this...
Washington, DC — Volcanic rock samples collected during NASA’s Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those...

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the...
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...
Carnegie scientists participate in NASA's Kepler missions, the first mission capable of finding Earth-size planets around other stars. The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement and popular interest surrounding the discovery of...
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...
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...
Rocks, fossils, and other natural relics hold clues to ancient environments in the form of different ratios of isotopes—atomic variants of elements with the same number of protons but different numbers of neutrons. Seawater, rain water, oxygen, and ozone, for instance, all have different...
