Abstract

High-magnification imaging of materials from Mars-related meteorites (NWA 16788, NWA 2737), asteroid Ryugu (C0068 and associated particles), and Chang’e-5 lunar samples consistently reveals microstructures resembling organized fibrous, tubular, and cellular architectures. These include vessel-like conduits, fiber bundles, concentric wall structures, and polygonal or circular compartments with uniform diameters, rounded wall profiles, and branching morphologies similar to terrestrial vascular and woody tissues.

Across these bodies, the recurring presence of aligned tubes, parallel fiber arrays, cell-wall-like laminae, and hierarchical modular organization suggests a non-random pattern incompatible with known mineral growth, melt-segregation, or shock-fracture processes.

We propose that these structures represent fossilized or templated biological microarchitectures, or the remnants of engineered composite materials, preserved through mineral replacement across multiple planetary materials. Their scale consistency, symmetry, and functional patterning motivate consideration of an extraterrestrial or technologically influenced origin.

1. Introduction

Meteorites, asteroid-returned samples, and lunar regolith fragments sometimes preserve fine microstructures whose morphology exceeds the predictive capacity of known abiotic processes. While previous research has emphasized chemistry (e.g., organics, isotopes), the morphological dimension—particularly at tens to hundreds of microns—remains critically underexplored.

Here, we conduct a cross-body morphological assessment of nine high-resolution images from:

• NWA 16788 (Martian meteorite) (see figure and description here.)

• NWA 2737 (Chassignite)   

   (see figures and descriptions here and here.)

• Chang’e-5 lunar samples   

   (see figures and descriptions here and here.)

• Asteroid Ryugu particles   

   (see figures and descriptions here, here, here and here)

These samples exhibit recurring “modules” or “cells” showing:

• Circular and polygonal compartments

• Fibrous and tubular bundles

• Branching channels

• Laminar wall structures

• Morphologies strongly analogous to woody tissue, tracheids, vessel elements, xylem fibers, and engineered carbon-fiber composites

Such architectures are not characteristic of known igneous cooling, shock metamorphism, or diffusion-limited aggregation patterns. We therefore evaluate whether the observed structures align better with:

1. Fossilized biological microstructures, or

2. Templated / engineered composite materials formed by an unknown technological process.

2. Results

2.1 NWA 16788 (Martian meteorite): Tubular and fibrous wood-like elements

The NWA 16788 image displays a network of parallel fibers, branching tubules, and rounded cell cross-sections. Walls are smooth and sharply bounded. Several structures resemble terrestrial vessel elements, showing consistent diameters (50–200 μm). Such regularity is not typical of igneous microfractures or vesicle remnants.

2.2 NWA 2737 (Chassignite): Concentric laminae and fiber bundles

Two images from NWA 2737 reveal:

• Concentric wall layering, analogous to S1/S2/S3 laminae in wood

• Elongated tracheid-shaped compartments

• Fiber bundles arranged with directional uniformity

The organization suggests a growth-templated architecture rather than random cracking or shock deformation.

2.3 Chang’e-5 lunar samples: Honeycomb and vessel-like structures

Both lunar images exhibit:

• Tubular conduits resembling vascular vessels

• Elongated fibers

• Circular to elliptical cell cross-sections

• A honeycomb-like compartment arrangement

These are not common in basaltic vesicle textures, which lack concentric walls and rarely form uniform modular arrays.

2.4 Asteroid Ryugu particles: Micro- to nano-scale woody ultrastructure

Ryugu images show:

• Aligned nano-fibrils

• Tubular bundles

• Laminar sheets

• Cross-sectional circular units

These features resemble degraded plant fibers or engineered carbon-fiber composites. Their hierarchical organization suggests a multi-level template.

3. Discussion

3.1 Structural recurrence across planetary bodies

The multi-body recurrence of similar morphologies—vessel-like tubes, fibrous bundles, cell-like compartments—reduces the likelihood of coincidental abiotic generation.
Shared traits include:

• Repeating diameters

• Smooth lumens

• Laminar walls

• Parallel fiber alignment

• Hierarchical nano- to macro-architecture

These traits do not match known outputs of igneous or metamorphic processes.

3.2 Limitations of abiotic models

We evaluated several geological mechanisms, including:

• Vesicle formation

• Melt contraction cracks

• Shock fracturing

• Olivine exsolution

• Serpentinization

None adequately explain:

• Concentric cell-wall laminae

• Vascular-like tubes

• Uniform fibers

• Branching networks

• Nano-fibrillar bundles

3.3 Biogenic or engineered templates

The structural similarity to terrestrial wood, vascular tissues, and engineered fiber composites suggests that these architectures may derive from:

1. Ancient biological structures that underwent mineralization,

2. Engineered composite materials transported or distributed across multiple bodies, or

3. Unknown planetary processes capable of templating organized microstructures.

4. Conclusion

Repeated observation of organized, wood-like architectures in meteorites, asteroid samples, and lunar fragments indicates a cross-body pattern not easily explained by known geological processes. The evidence supports further consideration of a biogenic or technological origin preserved through mineral replacement.

5. Methods

Images were evaluated using morphological comparison to terrestrial biological and engineered structures, focusing on compartment geometry, laminar wall features, and fiber organization. No chemical or crystallographic data were available.
