Nature Communications, 2022 All DNA/RNA nucleobases were identified in carbonaceous meteorites. Having been provided to the early Earth as a component in carbonaceous meteorites, these molecules might have played a role for the emergence of genetic functions in early life.

The Nitrogen Heterocycle Content of Meteorites and Their Significance for the Origin of Life
Life, 2018 Carbonaceous chondrites are very primitive meteorites that are rich in carbon. They contain many soluble organic compounds, including nitrogen heterocycles.

Radon on Mars and the Moon derived from Martian and lunar meteorites [PDF]
Scientific ReportsThe radioactive gas radon-222, a fluid and aerosol tracer in Earth’s lithosphere and atmosphere, can also reveal subtle rock physics processes in extraterrestrial environments, such as those involving water, but remains poorly constrained in planetary ...

Connecting asteroids and meteorites with visible and near-infrared spectroscopy [PDF]
Icarus (New York, N.Y. 1962), 2022 • We search for spectral links among asteroid and meteorite classes by comparing 500 asteroid spectra and over 1,000 samples of meteorites over visible plus near-infrared (0.45–2.5 m) wavelengths. • We confirm established links, and also find less common

Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites
Science, 2022 Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids. Samples of the C-type asteroid (162173) Ryugu were retrieved by the Hayabusa2 spacecraft.

Magnetic Recording Stability of Taenite‐Containing Meteorites
Geophysical Research Letters, 2023 Sub‐μm taenite and tetrataenite grains observed in a number of (stony‐)iron meteorite groups are promising sources of paleomagnetic records in meteorites.

Arhaeoastronomical analysis of the Levinsadovka sacrificial complex (South Russia) [PDF]
Archaeoastronomy and Ancient Technologies, 2013 The article presents the results of a study of the unique sacrifice of the Levinsadovka sacrificial complex. On it were found large accumulations of animal bones near the buildings. An analogue of this sacrificial complex in the Northern Black Sea region

Earth’s water may have been inherited from material similar to enstatite chondrite meteorites
Science, 2020 An unexpected source of Earth's water The abundances of Earth's chemical elements and their isotopic ratios can indicate which materials formed Earth. Enstatite chondrite (EC) meteorites provide a good isotopic match for many elements but are expected to

AGU Advances, 2021 Magnetic fields in the early solar system may have driven the inward accretion of the protoplanetary disk (PPD) and generated instabilities that led to the formation of planets and ring and gap structures.

Possible Ribose Synthesis in Carbonaceous Planetesimals
Life, 2022 The origin of life might be sparked by the polymerization of the first RNA molecules in Darwinian ponds during wet-dry cycles. The key life-building block ribose was found in carbonaceous chondrites.
