Washington, DC— Up to now scientists thought that the trace amounts of carbon on the surface of the Moon came from the solar wind. Now researchers at the Carnegie Institution’s Geophysical Laboratory have detected and dated Moon carbon in the form of graphite—the sooty stuff of pencil lead—which survived from the late heavy bombardment era 3.8 billion years ago.

Planetary Science

Washington, DC—Scientists at the Carnegie Institution’s Geophysical Laboratory, with colleagues, have discovered a much higher water content in the Moon’s interior than previous studies.

Washington, DC — The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans.

Washington, DC—An unprecedented study of bald eagle diet, from about 20,000 to 30,000 years ago to the present, will provide wildlife managers with unique information for reintroducing Bald Eagles to the Channel Islands off California.
