Source Regions of Carbonaceous Meteorites and NEOs
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, including young […]
Meteorites and Planet Formation
Meteorites are a remarkable resource. They capture the imagination of people worldwide with their spectacular entry through Earth’s atmosphere as fireballs, and their exotic character of being pieces of other […]
Prebiotic Vitamin B3 Synthesis in Carbonaceous Planetesimals
Aqueous chemistry within carbonaceous planetesimals is promising for synthesizing prebiotic organic matter essential to all life. Meteorites derived from these planetesimals delivered these life building blocks to the early Earth, […]
Dating The Solar System’s Giant Planet Migration Using Chondrite Meteorites
The period of orbital instability that led to the migration of the Solar System’s giant planets to their current orbit occurred between 60 and 100 million years after the beginning […]
Climate Change Threatens Antarctic Meteorites
Using artificial intelligence, satellite observations, and climate model projections, a team of researchers from Switzerland and Belgium calculate that for every tenth of a degree of increase in global air […]
Gamma-Ray-Induced Amino Acid Formation During Aqueous Alteration in Small Bodies: The Effects of Compositions of Starting Solutions
Organic compounds, such as amino acids, are essential for the origin of life, and they may have been delivered to the prebiotic Earth from extra-terrestrial sources, such as carbonaceous chondrites.
Studying Life’s Origins By Simulating a Cosmic Evolution
Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals. Because of amino acids’ relationship to living things scientists are […]
Ryugu Samples Illuminate Terrestrial Weathering Effects On Primitive Meteorites
A groundbreaking study conducted by a team of international scientists has unveiled unprecedented insights into the nature of the asteroid Ryugu and shed light on the composition of water- and […]
Meteorites Were A Likely Source Of Nitrogen For Early Earth
Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That […]
