Potential Metabolic Viability On Asteroid Chemistry
While it has been long supposed that asteroids played a role in the delivery of important prebiotic compounds to early Earth, the exact nature of the interactions between asteroidal material […]
The Variety And Origin Of Materials Accreted By Bennu’s Parent Asteroid
The first bodies to form in the Solar System acquired their materials from stars, the presolar molecular cloud and the protoplanetary disk.
Workshop On Bennu And Ryugu: Samples From The Early Solar System
The Workshop on Bennu and Ryugu: Samples from the Early Solar System is scheduled for October 7–9, 2025, at the Lunar and Planetary Institute (LPI) in Houston, Texas.
NASA’s Bennu Samples Reveal Complex Origins, Dramatic Transformation
Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2020, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. Its […]
Asteroid Bennu Is A Time Capsule Of Materials Bearing Witness To Its Origin And Transformation Over Billions Of Years
Asteroid Bennu — the target of NASA’s OSIRIS-REx sample return mission, led by the University of Arizona — is a mixture of materials from throughout, and even beyond, our solar […]
Astrogeology: Asteroids Bennu And Ryugu Are Part Of The Polana Family
A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the […]
Formation of Lactic Acid (CH3CH(OH)COOH), a Metabolic Keystone for the Molecular Origins of Life, in Interstellar Ice Analogues
Lactic acid (CH3CH(OH)COOH)–a key biorelevant hydroxycarboxylic acid–is ubiquitous in living organisms and critically linked to the molecular origins of life due to its fundamental role in metabolic pathways.
Astrochemistry: Abiotic Origin Of Citric Acid Cycle Intermediates
The molecular framework for protometabolism-chemical reactions in a prebiotic environment preceding modern metabolism-has remained unknown in evolutionary biology.
An Unexpected Mineral Discovered In A Grain Of Asteroid Ryugu
The pristine samples from asteroid Ryugu returned by the Hayabusa2 mission on December 6, 2020, have been vital to improving our understanding of primitive asteroids and the formation of the […]
