Moon was produced by a head-on collision between Earth and a forming planet

Congratulations to Ed Young, Issaku Kohl, Paul Warren, and their collaborators on their paper “Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact” which appears in tomorrow’s edition of Science.

Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon

Research published this week in the Proceedings of the National Academy of Science by EPSS postdoc Beth Ann Bell, graduate student Patrick Boehnke, and Professor T. Mark Harrison, along with Stanford geophysicist Wendy Mao, provides evidence suggesting the existence of life on Earth before 4.1Ga. Their article " Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon" is garnering much attention from national and international news agencies*.

Greetings from the Chairman


In the Department of Earth, Planetary, and Space Sciences, we seek to understand the Earth and the planets. Our students, researchers, and faculty tackle a wide range of problems, from the Sun to the most distant planets, and from the center of the Earth to the tenuous ionized gases of the solar wind. We probe the interior of the Earth using seismic data, laboratory measurements, and computer modeling. We study both the ancient tectonics of the Earth and its ongoing activity. We explore Earth's upper atmosphere using spacecraft to measure magnetic fields and plasmas. Moving outward from Earth, we study other planets, their interiors, surfaces, atmospheres, and particle and field environments.
