Nature is messy, but 3I/Atlas is precise. Avi Loeb's latest analysis reveals a triple-jet system separated by exactly 120 degrees. We explore why this "lighthouse" behavior suggests the object isn't just tumbling—it's steering.

Overview

New analysis of Hubble Space Telescope images by Harvard astrophysicist Avi Loeb reveals a "symmetric jet structure" on interstellar object 3I/Atlas that is statistically impossible for a natural comet. The object exhibits a precise triple-jet system separated by exactly 120 degrees, alongside a massive "anti-tail" pointing directly at the Sun. With a rotation axis alignment that has a 0.2% chance of happening by accident, Loeb argues we are looking at a "lighthouse" effect—or something engineered.

Images of the jet structure of 3I/ATLAS from the Hubble Space Telescope, processed through the Larson-Sekanina rotation gradient filter, show a variable jet structure. The top panels zoom in on the inner jets within 24,000 kilometers from 3I/ATLAS on November 30, 2025 (top left), and December 27, 2025 (top right). Zooming out to the outer structure extending out to 100,000 kilometers, shown in the lower two panels for December 12 (bottom left) and December 27 (bottom right) is dominated by the anti-tail jet, directed at the Sun towards the lower left corner of the image.

Frequently Asked Questions

Nature is messy. Comets are messy. They are dirty snowballs that tumble randomly through the dark, spewing gas in chaotic plumes. But 3I/Atlas is not acting messy. It is acting... precise. In his latest analysis, Avi Loeb has pointed out a geometric symmetry in the object's jets that looks less like geology and more like engineering.

The Impossible Geometry

Using Hubble images from late 2025, Loeb identified a structure that should make every astronomer uncomfortable. On a small scale (within 10,000 km of the nucleus), 3I/Atlas isn't just venting gas; it is venting it in a pattern.

There are three distinct jets. One points away from the Sun, and the other two point sideways. The kicker? They are separated by almost exactly 120 degrees. In nature, "360 divided by 3" is a suspiciously perfect number to hit by accident. It suggests a balanced, potentially artificial distribution of mass or propulsion.

The "Lighthouse" Effect

Beyond the triple jets, there is the "anti-tail." This massive stream of particles extends 100,000 kilometers towards the Sun—a behavior that defies the solar wind. For this to happen, the object's rotation axis must be perfectly aligned with the Sun.

Loeb calculated the odds of this alignment happening randomly for a tumbling interstellar rock: 0.2%. That is a 1 in 500 chance. He compares the movement of the anti-tail to the "beam of a lighthouse," precessing in a tight, stable cone. Natural comets tumble; 3I/Atlas seems to be locked on target.

Loeb vs. NASA: The "Comet" Debate

While NASA and the ESA are content to label 3I/Atlas a "weird comet," Loeb is tallying the anomalies. We are now up to 15 distinct behaviors that don't fit the standard model:

Non-gravitational acceleration without visible outgassing (initially).

A rotation period that maintains stability despite massive mass loss.

The "impossible" sunward jet.

The symmetric 120-degree separation of inner jets.

Mainstream science says, "It's a rare comet." Loeb asks, "How rare does it have to be before we admit it might be something else?"

What Then? Nature Doesn't Do Math

At What Then Studio, we look for the "too perfect" moments. When you see a rock in the forest, you assume it's nature. When you see a pyramid, you assume intent. The 120-degree symmetry of 3I/Atlas's jets is the cosmic equivalent of finding a pyramid on Mars.

If this object is stabilizing itself using a triple-jet system, we aren't looking at a comet. We are looking at a probe correcting its course. And if it's looking at the Sun, maybe it's recharging.

Frequently Asked Questions

1. What is the "anti-tail"?

An anti-tail is a spike that appears to point toward the Sun, opposite to a normal comet tail. While it can be an optical illusion caused by viewing angles, 3I/Atlas's anti-tail is persistent and physically massive, suggesting a real stream of particles being ejected sunward.

2. Is 3I/Atlas leaving the solar system?

Yes. It is on a hyperbolic trajectory, meaning it will swing past the Sun and be ejected back into interstellar space, likely never to return. This was our one chance to see it.

3. Has NASA confirmed the jets are artificial?

No. NASA maintains that 3I/Atlas is a natural object with unusual properties. The "artificial" theory is primarily championed by Avi Loeb and the Galileo Project based on statistical anomalies in the data.
