Earth & Planetary Science Stories
Washington, D.C.— The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of...
Washington, DC — A team of scientists, including Carnegie's Conel Alexander and Jianhua Wang, studied the hydrogen in water from the Martian interior and found that Mars formed from similar building...
Washington, D.C.—Astronomers have discovered a new super-Earth in the habitable zone, where liquid water and a stable atmosphere could reside, around the nearby star HD 40307. It is one of three new...
Washington, D.C.--Scientists with the Giant Magellan Telescope Organization have completed the most challenging large astronomical mirror ever made. The mirror will be part of the 25-meter Giant...
Washington, D.C. — For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. According to this theory, the shock wave also injected...
Washington, D.C.— Comets and asteroids preserve the building blocks of our Solar System and should help explain its origin. But there are unsolved puzzles. For example, how did icy comets obtain...
Washington, D.C. — In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to...
Washington, DC —Scientists have long believed that comets and, or a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth's volatile elements—which include...

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 -...
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 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...
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...
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...
