As someone who has spent forty years toggling between guitar solos and routing packets, between the harmony of a chord progression and the precision of a network handshake, the arrival of 3I/ATLAS (also designated C/2025 N1) feels like watching an alien chord change in the cosmic symphony. Hereโs a detailed unpacking of what we do know about 3I/ATLAS, what remains puzzling, and how the provocative commentary from astrophysicist Avi Loeb fits (or wildly diverges) from the mainstream view.
1. Discovery, Trajectory & Basic Facts
3I/ATLAS was discovered on 1 July 2025 by the Asteroid Terrestrialโimpact Last Alert System (ATLAS) telescope in Rรญo Hurtado, Chile. (Astrobiology)
Its orbit is strongly hyperbolic, meaning it is not bound to the Sun and is passing through the Solar System only once (unless perturbed). (NASA Science Assets)
Some key numbers: perihelion (q โ 1.35) AU, eccentricity ~6.14, and incoming โhyperbolic excess velocityโ on the order of ~60 km sโปยน. (NASA Science)
Its size is still uncertain: Hubble observations constrain its nucleus to be not more than ~5.6 km diameter (or ~1,444 ft to ~3.5 miles) but some analyses suggest larger bounds (depending on assumptions). (NASA Science)
Age estimates place its origin at 3-14 billion years ago (outside our Solar System, likely from the Galactic thick disk). (Wikipedia)
As a network engineer, I like to visualize orbit parameters like packet paths in a network topology: this one is clearly โforeign-network trafficโ entering our local subnet once, and leaving forever.
2. Composition & Activity: What We Observe
From a โmusic geniusโ vantage Iโm listening for the instrumentation of this cometโwhat materials, what volatiles, what signals it broadcasts.
COโ dominance & water scarcity
Observations by the James Webb Space Telescope (JWST) show that the coma (i.e., the gaseous envelope around the nucleus) is strongly dominated by carbon dioxide (COโ) relative to water (HโO). Specifically a COโ/HโO mixing ratio of ~8.0 ยฑ 1.0 was observed at ~3.32 AU inbound. (arXiv)
Additionally, the SPHEREx mission detected a COโ-rich coma extending to at least ~348,000 km in radius. (SPHEREx)
Water activity was detected via the OH (hydroxyl) emission line using the Neil Gehrels Swift Observatory at ~3.51 AU, with a water production rate ~1.35 ยฑ 0.27 ร 10ยฒโท molecules sโปยน (~40 kg/s) and the implication that >20โ% of the surface might be active. (arXiv)
From a chemistry perspective: this is unusual for comets from our Solar System, which typically have much larger proportions of water relative to COโ at those distances.
Polarimetric & spectral oddities
A recent polarimetric study found a โdeep and narrow negative polarisation branchโ reaching about โ2.7% at ~7ยฐ phase angle and an inversion angle ~17ยฐ. These numbers are outside the usual range for either comets or asteroids. (arXiv)
Spectroscopy in optical/NIR shows a red slope (~10% per 1000 ร between 0.5-0.8 ยตm) flattening at longer wavelengths, consistent with ~30 % water-ice grains mixed with a Tagish Lake-type meteorite analog in the coma. (arXiv)
Nickel (Ni) emission and Ni/Fe anomalies
One of the more striking recent findings: in a paper titled โExtreme Ni I/Fe I abundance ratio in the coma of the interstellar comet 3I/ATLASโ, observations with ESOโs VLT UVES spectrograph found nickel (Ni I) emission at multiple epochs, but iron (Fe I) only detected at smaller heliocentric distances (โค2.64 AU). The Ni/Fe abundance ratio is exceptionally high compared to solar system comets. (arXiv)
Independent commentary (by Avi Loeb) points to a hypothesis of nickel tetracarbonyl (Ni(CO)โ) formation as a plausible mechanism for the high Ni and low Fe, describing the pathway as โa process that we can imagine only because it was used in industryโ. (Medium)
From a network-engineerโs lens: if typical comets are โbroadband trafficโ of ice + dust + standard metals, 3I/ATLAS is presenting a weird encrypted packet type with non-standard headers (Ni without Fe, COโ-rich, unusual tail orientation). As a music lover, itโs like a jazz piece where all your expected cadences are inverted or omitted.
3. Why the Speculation? Avi Loebโs Perspective
Avi Loeb, known for provocative takes (e.g., on 1I/สปOumuamua), brings forward a series of observations and hypotheses about 3I/ATLAS, some of which are more speculative than mainstream. Iโll lay them out respectfully and then comment with my dual-perspective.
Loebโs key speculative points:
He emphasises that the Ni emission without concurrent Fe is unprecedented in known comets, and in his view hints at either exotic chemistry or technological origin. (The Economic Times)
He highlights the observation of an anti-tail (a tail pointing toward the Sun rather than away) and suggests it might represent a โbraking thrustโ or active manoeuvre rather than purely sublimation. (New York Post)
He uses what he calls the โLoeb Scaleโ of object-origin likelihood (0 = natural rock, 10 = confirmed technology) and reportedly assigns 3I/ATLAS a mid-to-high number (though he emphasises it is not definitively artificial). (reddit.com)
Loeb cautions that if this object is technological, the implications โare so huge for humanityโ and that we should maintain open-mindedness. (New York Post)
My commentary (music-meets-network-engineer lens):
As a musician, I adore thematic deviations: when a piece changes key unexpectedly or introduces an instrumentation you didnโt expect, you pay attention. 3I/ATLAS is that in the cosmic concert: COโ-rich, Ni-emitting, Fe-lacking, with an odd tail orientation. These are valid anomalies worthy of investigation.
As a network engineer, Iโm sleuthing for protocol anomalies: missing handshake, unexpected payload, odd routing. If a comet is โexpected traffic,โ this one is more like an unknown protocol or even a disguised spoof.
But: anomalous โ artificial. Cavernous data flows exist in nature; exotic chemistry can arise under unusual formation conditions (e.g., high-radiation environments, low metallicity, unique parent star systems). Loeb is right: we must consider all possibilities, but as an engineer I also demand reproducible logs and error-checking before declaring โforeign packet source.โ
Loebโs stance: he isnโt (to my reading) claiming itโs alien tech, but rather saying: โGiven the oddities, we should remain humble and keep all options open.โ Thatโs healthy scientific posture but inevitably draws sensational headlines.
4. Outstanding Questions (and My Speculative Plays)
Here are some of the puzzles I find especially tantalising, with my engineer/harmonist speculation:
Question
What the data shows
My speculative thought
Why such a high COโ/HโO ratio?
JWST measured COโ/HโO โ 8.0 ยฑ 1.0, unusually high for a comet at ~3.3 AU. (arXiv)
Could suggest formation beyond the COโ ice-line in its parent system, or heavy radiation exposure depleting HโO ice. Imagine a string section missing the violins.
Why Ni but little/no Fe?
VLT spectra show Ni emissions at multiple epochs; Fe only appears (if at all) at smaller distances, producing an extreme Ni/Fe ratio. (arXiv)
One speculation: nickel-carbonyl (Ni(CO)โ) or Ni bound organometallics sublimating easily; iron might be locked in larger refractory phases not yet sublimating. In music terms: youโre hearing a drum solo but missing the bass line.
Why an anti-tail / sun-pointing jet?
Observations report a tail (or coma extension) toward the Sun rather than the usual away-from-Sun tail. (IFLScience)
Could be an anisotropic outgassing jet caused by local geometry. Or (speculatively) a manoeuvre-like effect. As an engineer: if the exhaust points toward the Sun, something is intentionally โbrakingโ the motion relative to solar gravity.
Why no large visible dust tail (yet) or what appear to be standard โcometโ features?
Some images show only a faint coma, not a huge dust tail. (Astrobiology)
Perhaps the dust grains are large and not being accelerated by radiation pressure, or sublimation is dominated by COโ/CO rather than HโO so the dust dynamics differ. Or the nucleus is so large/massive that dust ejection has less net effect.
What is its origin star/region?
Age estimate 7.6-14 billion years; trajectory from direction of Sagittarius, i.e., near the Galactic centre region for departure. (Wikipedia)
Perhaps formed in a low-metallicity, early-type star system. If so, its chemistry may differ markedly from Solar-System comets, producing the unusual composition.
5. My Conclusion: Symphony of the Unknown
From my vantage of forty years of listening to music, learning networks, and reading science, hereโs how I frame 3I/ATLAS:
It is every bit worthy of attention: we are looking not at a run-of-the-mill comet, but at a visitor from another star system, bringing its own โinstrumentationโ and playing a tune we havenโt heard before.
The major findings (COโ-dominance, unusual Ni/Fe, anti-tail) are real and documented in peer-review or arXiv. The anomalies are not just hype.
That said, the most dramatic speculation (technological origin, alien spacecraft) remains just thatโspeculation. Good speculation, thought-provoking, but not yet with conclusive evidence.
I personally lean toward a novel natural object hypothesis: a comet/planetesimal from a very different star system, formed under unusual conditions (different metallicity, different radiation history) so its composition and activity deviate from Solar-System norms. As my music analog: itโs jazz from another planet, not necessarily a beamed-in radio transmission.
But I also reserve the possibility that if future data reveals genuine manoeuvre-like behaviour (non-gravitational acceleration inconsistent with outgassing, highly directed jets, artificial materials) then we might need to reconsider more exotic scenarios.
6. What to Watch Next
If youโre as curious as I am, here are the things Iโll be tuning my sensors (and ears) for:
High-resolution images from missions (e.g., the HiRISE camera on the Mars Reconnaissance Orbiter reportedly imaged 3I/ATLAS near Mars) to better resolve nucleus size, shape, and dust environment. (Daily Galaxy)
Additional spectroscopic campaigns measuring Ni/Fe, CN, CO, OCS (carbonyl sulphide) and other volatiles as the object approaches perihelion (~29 October 2025) and recedes.
Precise astrometric tracking to detect non-gravitational acceleration (i.e., residual โthrustโ not explained by outgassing) which could hint at active processes.
Continued polarimetric and dust-tail morphology studies to understand grain size distributions and outgassing geometry.
Cross-comparison: how does 3I/ATLAS compare with 1I/สปOumuamua and 2I/Borisov? Are we seeing a spectrum of interstellar visitors or a special outlier?
Final Thought
In the grand network of cosmic events, 3I/ATLAS is a rare packet injected into our Solar-System subnet, carrying payloads that challenge expectations. As a musician, I feel the dissonance and want to resolve it into new harmony. As an engineer, I log the anomalies, check the protocols, and await confirmation. Avi Loebโs voice reminds us: maybe this isnโt just another cometโbut until the data plays out, the melody remains unresolved. Either way, being a part of this moment is exhilarating.
