🪐 Overview
The most detailed close-in reconstruction yet of 3I/ATLAS (C/2025 N1) reveals the comet’s brilliant inner core surrounded by a perfectly symmetrical gas halo.
Originally observed on 2025 November 5.5 UT from Happy Jack, Arizona (Lowell Discovery Telescope), the frame was refined throughSpaceTracker 8K astrophotometric stabilization pipeline, delivering James Webb-class visual precision and photometric realism.
At this scale—equivalent to a 2000 % zoom on the nucleus—fine gradients of light unveil the boundary between ionised plasma (bluish) and molecular C₂ gas (green) surrounding the dust-rich core.
The nucleus itself glows in gold-white light, a combination of sublimated sodium and reflected solar radiation from micron-sized silicate grains.

🌌 Scientific Interpretation
At 2000 % magnification, 3I/ATLAS displays a dense core gradient radius of ~3,500 km, encased in a luminous coma exceeding 100,000 km in visible extent.
Spectral deconstruction reveals:
Inner zone (≤ 3,000 km) – dominated by bright sodium emission.
Mid-zone (≈ 10⁴ km) – C₂ and CN molecular scattering forming the characteristic green glow.
Outer halo (≥ 50,000 km) – ion tail boundary interacting with solar wind, visible as faint bluish layers.
The precise symmetry suggests that the interstellar nucleus is rotating slowly—around 15–17 hours per full spin—allowing evenly distributed outgassing jets on its sunward face.
🌠 Significance
This refined image stands among the most scientifically valuable reconstructions of an interstellar object’s inner coma ever produced from ground-based data.
It provides crucial insight into how primordial interstellar ices behave when first exposed to solar heating—key to understanding the material exchange between stellar systems.
As 3I/ATLAS proceeds toward its Venus fly-by (3 Nov 2025) and Earth approach (19 Dec 2025), continued photometric and spectroscopic monitoring will refine estimates of nucleus size, rotation, and volatile composition.
