Nat Astron
. 2025 Feb;
9(2):199-210.
PMID: 39990238
Organic matter in meteorites reveals clues about early Solar System chemistry and the origin of molecules important to life, but terrestrial exposure complicates interpretation. Samples returned from the B-type asteroid...

Nat Astron
. 2025 Jan;
7(2):182-189.
PMID: 39776490
Initial analyses showed that asteroid Ryugu's composition is close to CI (Ivuna-like) carbonaceous chondrites -the chemically most primitive meteorites, characterized by near-solar abundances for most elements. However, some isotopic signatures...

Spitzer F, Kleine T, Burkhardt C, Hopp T, Yokoyama T, Abe Y, et al.
Sci Adv
. 2024 Sep;
10(39):eadp2426.
PMID: 39331721
The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu/CI chondrites formed...

Morita M, Yui H, Urashima S, Onose M, Komatani S, Nakai I, et al.
Anal Chem
. 2023 Dec;
96(1):170-178.
PMID: 38155534
Characterization of the elemental distribution of samples with rough surfaces has been strongly desired for the analysis of various natural and artificial materials. Particularly for pristine and rare analytes with...

Yokoyama T, Wadhwa M, Iizuka T, Rai V, Gautam I, Hibiya Y, et al.
Sci Adv
. 2023 Nov;
9(45):eadi7048.
PMID: 37939187
Studies of material returned from Cb asteroid Ryugu have revealed considerable mineralogical and chemical heterogeneity, stemming primarily from brecciation and aqueous alteration. Isotopic anomalies could have also been affected by...

Nguyen A, Mane P, Keller L, Piani L, Abe Y, Aleon J, et al.
Sci Adv
. 2023 Jul;
9(28):eadh1003.
PMID: 37450600
Preliminary analyses of asteroid Ryugu samples show kinship to aqueously altered CI (Ivuna-type) chondrites, suggesting similar origins. We report identification of C-rich, particularly primitive clasts in Ryugu samples that contain...

Science
. 2023 Jan;
379(6630):372-376.
PMID: 36701465
Meteorites record processes that occurred before and during the formation of the Solar System in the form of nucleosynthetic anomalies: isotopic compositions that differ from the Solar System patterns. Nucleosynthetic...

Sci Adv
. 2022 Dec;
8(50):eade2067.
PMID: 36525483
The extraterrestrial materials returned from asteroid (162173) Ryugu consist predominantly of low-temperature aqueously formed secondary minerals and are chemically and mineralogically similar to CI (Ivuna-type) carbonaceous chondrites. Here, we show...

Sci Adv
. 2022 Oct;
8(46):eadd8141.
PMID: 36264823
Little is known about the origin of the spectral diversity of asteroids and what it says about conditions in the protoplanetary disk. Here, we show that samples returned from Cb-type...
