New Developments:

1. The Hubble Space Telescope captured something unusual.
2. Three evenly spaced jets — not random, not chaotic — emerging symmetrically from the nucleus of 3I/ATLAS.
3. Now, the debate is no longer whether the object is active — it’s whether its behavior is natural, engineered, or misunderstood.

[USA HERALD] - In a newly published analysis, Harvard astrophysicist Avi Loeb and Italian observer Toni Scarmato examined high-resolution images captured by the Hubble Space Telescope between November 30 and December 27, 2025.

Using a specialized image-processing method known as the Larson–Sekanina rotational-gradient filter, they removed the circular glow around the nucleus of 3I/ATLAS. What remained was stark:

• Three close-in jets spaced roughly 120 degrees apart
• A large sunward anti-tail on a broader scale
• Periodic “wobbling” behavior in the jet orientation

The most prominent jet oscillates with a period of approximately 7.2 hours. The total brightness of the object varies with a nearly identical 7.136-hour rhythm and swings by about 30 percent.

That synchronization is what has drawn attention.

Here’s what Loeb’s team is saying:

• 3I/ATLAS spins roughly every 7.1 hours.
• Its spin axis does not line up perfectly with its internal shape.
• That misalignment causes a wobble — like a slightly off-balance spinning top.
• As it wobbles, its jets appear to shift from tight beams to wider fan shapes.
• That shift causes the brightness to rise and fall.

Two additional jet periods were detected:
• Jet 2 at 2.9 hours
• Jet 3 at 4.3 hours

Those numbers add up to 7.2 hours — reinforcing the rotation interpretation.

Loeb’s conclusion: the triple-jet system could be caused by natural sublimation of ice pockets. But he does not rule out the alternative — that the jets could represent technological thrust mechanisms.

That is the unresolved question.

Why This Matters

3I/ATLAS is approximately 2.6 kilometers in diameter. According to prior measurements, only about 1% of its brightness comes from sunlight reflecting off its surface. The rest is from active material being expelled.

In other words — it’s not just drifting. It’s doing something.

Multiple jets positioned symmetrically could stabilize rotation. In spacecraft engineering, thrusters are arranged symmetrically to prevent tumbling.

Natural comets also vent gas in multiple directions — but usually in irregular patterns tied to uneven heating.

The debate is over symmetry and timing.
