Evidence Blasted Into Space: Mystery Why Some Meteorites Look Less Shocked Solved
Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery […]
The Source Of Hydrogen In Earth’s Building Blocks
Due to their isotopic similarity to terrestrial rocks across a range of elements, the meteorite group that is thought to best represent Earth’s building blocks is the enstatite chondrites (ECs).
A Case Study of Interstellar Material Delivery: Alpha Centauri
Interstellar material has been discovered in our Solar System, yet its origins and details of its transport are unknown. Here we present α Centauri as a case study of the […]
Phosphates on Mars and Their Importance as Igneous, Aqueous, and Astrobiological Indicators
This paper reviews the phosphate phases in meteorites and those measured by landed spacecraft, what they reveal about past igneous and aqueous conditions on Mars, and important implications for potential […]
Antarctic Search for Meteorites Program (ANSMET) Report October 2024
Early last February, ANSMET returned home from a short but successful field season: we recovered 208 meteorites in just over two weeks in our first return to Antarctica since the […]
Sea Foam Contains Hemoglycin From Cosmic Dust
In-falling cosmic dust has left evidence of meteoritic polymer amide in stromatolites, both fossil and modern.
The Sun’s Birth Environment: Context for Meteoritics
Meteorites trace planet formation in the Sun’s protoplanetary disk, but they also record the influence of the Sun’s birth environment.
Unraveling the Interface Chemistry Between HCN And Cosmic Silicates By The Interplay Of Infrared Spectroscopy And Quantum Chemical Modeling
Understanding the interaction between hydrogen cyanide (HCN) and silicate surfaces is crucial for elucidating the prebiotic processes occurring on interstellar grain cores, as well as in cometary and meteoritic matrices.
Astronomers Clarify How Organic Macromolecules Are Formed
An international team of researchers led by the University of Bern has used observation-based computer modelling to find an explanation for how macromolecules can form in a short time in […]
