Oldest Impact Structure on Earth Identified
A study led by Timmons Erickson of Jacobs/NASA Johnson Space Center has identified Yarrabubba, a 70-kilometer-diameter crater in Western Australia, as the oldest impact structure on Earth. Rock samples from […]
Bio-essential Sugars Found in Meteorites
A study published in the Proceedings of the National Academy of Sciences reports the presence of ribose and other bio-essential sugars, including arabinose and xylose, in two carbonaceous meteorites, Murchison […]
Constraining the Impact History of the Moon with Lunar Impact Glasses
Lunar impact glasses are formed when the Moon’s crust melts during an impact event and subsequently quenches as a glass. The observed spectrum of impact glass ages helps to constrain […]

NASA Mars Weathercam Helps Find Big New Crater
Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter. The crater spans […]
NASA Mars Orbiter Examines Dramatic New Crater
Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in […]
