1 day ago · The 120 g of material came from the near-Earth asteroid 101955 Bennu, which OSIRIS-REx visited in 2020. ... Amino acid molecules lack rotational symmetry – think of how, no matter how much you twist or turn your left hand, you will never be able to superimpose it on your right hand. As such, amino acids can randomly be either left- or right ...

2 days ago · Abundant Ammonia and Nitrogen-Rich Soluble Organic Matter in Samples from Asteroid (101955) Bennu - 2025 ... We detected amino acids (including 14 of the 20 used in terrestrial biology), amines, formaldehyde, carboxylic acids, polycyclic aromatic hydrocarbons and N-heterocycles (including all five nucleobases found in DNA and RNA), along with ...

Jan 29, 2025 · The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) mission collected pristine material from the well-characterized surface of primitive...

Jan 31, 2025 · I've been waiting to see the results of analyzing the samples of asteroid (101955) Bennu returned by the OSIRIS-REx mission, and they've just come out. At right is a shot of the probe collecting a sample in 2020; the capsule was returned to Earth in 2023. ... The total concentration of amino acids in the Bennu sample is several-fold higher than ...

4 days ago · NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino acids and nucleobases found in DNA and RNA. The presence of ammonia and formaldehyde suggests conditions ripe for forming complex molecules in space. ... (101955) Bennu” by Daniel P. Glavin, Jason P. Dworkin, Conel M ...

Jan 29, 2025 · Here we show that Bennu samples are volatile rich, with more carbon, nitrogen and ammonia than samples from asteroid Ryugu and most meteorites. Nitrogen-15 isotopic enrichments indicate that...

We detected amino acids (including 14 of the 20 used in terrestrial biology), amines, formaldehyde, carboxylic acids, polycyclic aromatic hydrocarbons and N-heterocycles (including all five...

Introduction: Samples collected from the surface of carbonaceous B-type asteroid (101955) Bennu and returned to Earth in September 2023 by the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith

(101955) Bennu. This absorption is indicative of carbon species, including organics, on the sur-face. Aims. We aim to describe the composition of the organic matter on Bennu by investigating the spectral features in detail. Methods. We use a curated set of spectra acquired by the OSIRIS-REx Visible and InfraRed

We identified ammonia and complex suite of amino acids and amines of extraterrestrial origin in Bennu aggregate samples. The distinct distribution may reflect a unique parent body formation environment, chemical composition, and/or alteration history.
