Where on Earth Did the Moon’s Water Come From?

  Water is perhaps the most important molecule in our Solar System. Figuring out where it came from and how it was distributed within and among the planets can help scientists understand how planets formed and evolved. New research from a team including Carnegie’s Erik Hauri demonstrates that water from the interiors of the Earth [continue reading]

Meteorite "Paris" Contains Similar Organics as the Interstellar Medium

  A team of researchers from the Institute of Space Astrophysics (IAS / CNRS-Université Paris Sud) examining the meteorite “Paris”,  was able to highlight the presence of organic components similar to those of the interstellar medium. Fig.2: This photograph shows the Paris meteorite fusion crust (croute de fusion) formed during atmospheric entry partially oxidized (orange) traces (traces d’oxydation) [continue reading]

The Source of Earth’s Water is... Solar System Ice

  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 hydrogen, nitrogen, and carbon—and possibly organic material, too. Understanding where these volatiles came from is crucial for determining the origins of both water and life on the planet. [continue reading]

Newly Found Primitive Mineral in the Allende Meteorite

  In 1969, an exploding fireball tore through the sky over Mexico, scattering thousands of pieces of meteorite across the state of Chihuahua. More than 40 years later, the Allende meteorite is still serving the scientific community as a rich source of information about the early stages of our Solar System’s evolution. Recently, scientists from [continue reading]
