The evolution of early Earth was significantly influenced by collisions of planetary materials with Earth’s surface. It is generally accepted that these events modified the composition of Earth’s atmosphere and […]
Asteroids are small, rocky bodies that can provide clues to the primitive composition of our solar system and how organic material was delivered to Earth. Many of the most primitive […]
Meteorite impacts on Earth are mostly known for forming recognizable craters such as the Barringer Meteorite Crater in Arizona that are easily distinguished in the geologic record. Large airbursts occur […]
Polymorphs of a mineral are different forms that have the same chemical composition but different atomic structures. These different atomic arrangements reflect the pressures and temperatures, and ultimately the geological […]
Understanding the history of asteroid impacts on Earth is important because large impacts play a critical role in the evolution of Earth’s natural systems such as its atmosphere, biosphere, and […]
Evidence of an extraterrestrial origin for the demise of the dinosaurs 66 million years ago was first found in the form of a geochemical signature — an anomaly in the […]
The lunar surface is littered with relicts of impacts large and small that have obfuscated the ancient geologic record of the Moon. Zircon (SiO4) is a mineral often used to look […]
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 […]
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 […]
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 […]
Impacts and Their Role in the Evolution of Life Conference, Tällberg, Siljan Crater Area, Sweden, June 10-13, 2019 The following themes will be covered by the meeting: Impacts, the Early History of […]
Dear impact science colleagues, We would like to announce the following exciting session at the EPSC-DPS Joint Meeting 2019 (September 15–20, 2019 | Centre International de Conférences de Genève (CICG) | […]
A recent study, published in the journal Meteoritics and Planetary Science by Hamann et al. reports new petrographic observations that demonstrate liquid immiscibility in impact melts. Immiscibility is when two […]
Date: May 14 – 17, 2018 Place: Kobe, Japan http://www.impact-res.org/CD2018/Catastrophic_Disruption_2018/Welcome.html CD9 will bring together experts from around the world who study the catastrophic disruption in the Solar System through simulations […]
35th International Geological Congress PLANETARY SCIENCES AND METEORITE IMPACTS SESSION August 27 – September 4, 2016 Capetown, South Africa With the recent increase in the exploration of the planets and solar […]
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 […]
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 […]
