Abstract:
Recent high-resolution imaging from China’s Chang’e 5 lunar mission reveals a series of microstructures in lunar samples that closely resemble vascular wood cells, including vessel elements, fibers, and parenchyma cells. Using annotated electron microscope images and contextual surface photos, this article presents a systematic analysis of these structures, their morphological alignment with terrestrial wood anatomy, and addresses potential abiotic counter-interpretations. Comparative arguments are made against natural geological formation processes, and the lack of earthly analogs is emphasized.

Introduction
The discovery of biological-like microstructures on planetary bodies is of paramount astrobiological significance. This study focuses on several annotated images from the Flickr album “Man‑Made Wood Cells on the Moon” (https://www.flickr.com/photos/fossil_lin/albums/72177720324971951/), where repeated patterns resembling fossil wood tissue appear in high-resolution photos taken by the Chang’e 5 mission. These patterns include elongate tubular structures, rounded or polygonal cross-sections, and aligned fibril-like textures. We systematically assess these images and evaluate whether natural mineral, sedimentary, or impact-related geological processes can plausibly explain their complexity, geometry, and regularity.

Figure-Based Observations

Figure 1. [https://www.flickr.com/photos/fossil_lin/54413342630]

• Red arrows: Indicate cross-sections of large circular and polygonal structures resembling transverse cuts through vessel elements.

• Green arrows: Point to elongate structures with parallel walls and rounded ends, consistent with wood fibers.

• Yellow arrows: Indicate clustered or square-shaped features consistent with parenchyma cells.

• Source: SEM image of Lunar Fragment B001, from Chang’e 5 (originally published by Beijing SHRIMP Center, Phys.org).

Figure 2. [https://www.flickr.com/photos/fossil_lin/54415036991]

• A high-resolution context image from the same Chang’e 5 site. Red arrows show cross-cut wood-cell-like structures visible on the exposed regolith surface. Green arrows trace longitudinal vessel alignments. This supports morphological continuity across scales.

Figures 3–5.

• Additional photos [e.g., https://www.flickr.com/photos/fossil_lin/54367001685] show consistent wood-grain-like textures, clusters of hollow tubes, and repeating biomimetic cell arrangements.

Comparison with Terrestrial Fossil Wood
Terrestrial petrified wood displays the same organization:

• Vessel elements: large, round to oval voids aligned vertically or in cross-section.

• Fibers: narrow, elongate cells that provide structural rigidity.

• Parenchyma: blocky cells arranged between vessels and fibers.

The lunar structures exhibit comparable sizes (often 10–50 µm), alignments, and preservation morphology, despite occurring in regolith with no plausible known biological source.

Discussion: Rebuttal of Abiotic Hypotheses
The following geological processes have been proposed as abiotic alternatives:

1. Differential Erosion / Weathering

• Rebuttal: The lunar environment lacks water, wind, or atmosphere to drive typical erosion. Structures are embedded, not surface-weathered.

Jointing and Fracturing

• Rebuttal: Fractures do not produce repeated cylindrical or polygonal lumens with cell-like wall boundaries.

Mineral Veins / Deposition

• Rebuttal: Vein networks are irregular and do not create ordered circular cellular patterns at this scale.

Ventifacts / Wind Abrasion

• Rebuttal: The Moon’s near-vacuum excludes this mechanism entirely.

Sedimentary Laminations

• Rebuttal: Sediments do not naturally produce transverse ringed structures or hierarchically organized tubes like those seen here.

Absence of Earth Analogs
No known terrestrial igneous, metamorphic, or sedimentary rocks exhibit the precise arrangement of cross-cut hollow cylinders, fiber tubes, and vessel clusters shown in these lunar photos. Despite extensive searches in geological image archives, there are no convincing matches to the Chang’e 5 structures in known Earth rocks.

Conclusion
The lunar microstructures revealed in Chang’e 5 imagery consistently display biological-like features that mirror those of fossilized wood tissue. Their geometry, dimensional consistency, and organization contradict known abiotic geologic mechanisms and lack parallels in Earth’s natural mineralogy. The possibility of artificial or bio-templated origin—while extraordinary—cannot be dismissed based solely on current evidence. These findings warrant further direct investigation of lunar microstructures using in situ spectroscopy and nanoscale imaging.
