3I/ATLAS is, without any exception or uncertainty, an interstellar comet. It is not an alien spacecraft, and there is zero evidence to suggest otherwise.

The claims are striking, the visuals compelling, and the engagement high. Unfortunately, the science is neither mysterious nor alien.

This pattern is now familiar. Whenever an unusual astronomical object is detected, social platforms quickly fill with pseudo-scientific speculation.

Algorithms reward content that shocks, not content that informs, and bad actors have access to increasingly sophisticated tools to fabricate imagery that appears authentic at first glance. The claims around 3I/ATLAS represent a textbook case of how misinformation metastasises in real time.

Experts Say No Threat To Earth

“So that’s going to be around twice the distance of  Earth and sun, it is going to be passing the Earth on the other side. So there’s a lot of distance,” Gurdemir said.

Gurdemir is also the director of the Planetarium at UTA, where they can track various celestial events in space, including interstellar visitors.

Life forms from other galaxies and planets is a much deeper conversation for him. That could mean water or a plant. 3I/Atlas does mean alien forces will veer toward Earth with high-powered lasers zapping down buildings.

“There is no information to say this is anything other than all the ordinary visiting comment, which happened before in  2017 in 2019, and now in 2025,” he said.

University of Texas at Arlington Astrophysicist Levent Gurdemir said the visitor to our solar system probably originated from a disk around another star. It became known as 3I/Atlas.

“3I/Atlas, as much as we can tell so far, is a comet coming from interstellar comet coming from outside of the solar system,” Gurdemir said.

According to NASA, an Asteroid Terrestrial-impact Last Alert System in Chile reported the speeding object on July 1. NASA also noted that there are additional discoveries dating back to June 14.  

It was called “3I” because it is the third known interstellar object from outside of our solar system. The ATLAS comes from the Asteroid Terrestrial-impact Last Alert System.

“We’ve seen a lot of things in the sky moving across, sometimes it’s a satellite,” Gurdemir said. “Sometimes it’s a meteor. Sometimes it’s an— you know, the comet.”

3I/ATLAS – (TRUE FACTS)

Comet 3I/ATLAS is the third known interstellar object to pass through our solar system, arriving from beyond our Sun’s neighborhood.

Discovered in July 2025, it follows a hyperbolic orbit, moving too quickly to be captured by the Sun’s gravity, and will leave the solar system after its flyby.

Scientists are examining its unusual composition—particularly its high carbon dioxide ice-to-water ice ratio—to gain insight into how other star systems form.

Key Facts About 3I/ATLAS

• Origin: An interstellar comet from another star system, likely ejected billions of years ago.
  
  
• Discovery: Detected on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii.
  
  
• Orbit: Hyperbolic, meaning it is unbound and will pass through the solar system just once before heading back into deep space.
  
  
• Speed: Travels at roughly 250,000 km/h (155,000 mph) at its closest approach to the Sun.
  
  
• Composition: Early observations by the James Webb Space Telescope revealed a strikingly high carbon dioxide ice-to-water ice ratio of 8:1, a clue to the conditions in distant planetary systems.
  
  
• Closest Approach: It poses no threat to Earth, passing at about 270 million km (1.8 astronomical units).
  
  
• Visibility: Observable with ground-based telescopes through September 2025, it became too close to the Sun to see until early December 2025, when it will emerge on the opposite side.

Tech Business News reports that six deepfake videos purporting that the interstellar object 3I/ATLAS is actually an alien spaceship are circulating widely on Facebook — and that Meta has so far refused to remove them, despite multiple reports.

The synthetic-media attacks are not a harmless prank: they risk eroding public trust in real science and amplifying conspiratorial narratives about a comet that, in truth, is entirely natural.

Many of the posts falsely assert that NASA has “confirmed” non-human technology, often accompanied by AI-rendered videos depicting spacecraft-like structures or “leaked” telescope footage.

A number of circulated images show sharp metallic surfaces or structured geometric patterns — telltale signs of AI-generated artifacts but convincing enough to those unfamiliar with astronomical imaging.

Meanwhile, deepfake videos impersonating scientists have begun appearing, echoing the same unfounded storylines.

The reality, however, is far more grounded — and scientifically valuable.

3I/ATLAS is not an alien craft but an active comet. As with any comet, its structure is well understood: a solid icy nucleus surrounded by a coma, the hazy envelope of gas and icy dust that forms as sunlight warms the nucleus and causes material to sublimate into space.

The resulting glow and tail are natural, predictable phenomena. Variations in brightness — another feature miscast online as evidence of propulsion or artificial lighting — are completely normal for active comets and often result from shifts in outgassing as they approach or recede from the Sun.

The “3I” designation simply indicates that it is the third recognised interstellar object to pass through our solar system, following 1I/‘Oumuamua and 2I/Borisov.

Interstellar comets are rare, but they are not inexplicable. They are believed to be ejected from other planetary systems through gravitational interactions and travel for millions of years before entering ours.

Yet the mythmaking around 3I/ATLAS highlights a growing challenge for science communication. The tools for fabricating persuasive misinformation are evolving faster than the public’s ability to develop media literacy.

At the same time, official astronomical images — often low-resolution, faint, or highly processed — cannot compete visually with stylised, AI-fabricated “evidence.” When those fabrications align with cultural expectations of what a “spaceship” should look like, the debunking becomes even more difficult.

Editorially, this moment calls for renewed vigilance. Journalists, educators, and scientific institutions must not only report the facts but also contextualize why false stories spread and how to recognise them.

Social media companies, for their part, must confront the role their platforms play in amplifying fabricated content, especially when it impersonates legitimate scientific sources.

3I/ATLAS, has drawn the interest of Harvard astronomer Avi Loeb, who is well-known for his provocative claims that earlier interstellar visitors might be remnants of an extraterrestrial civilization.

Although most astronomers now agree that the new object is likely a comet, Loeb continues to suggest that it could have been sent by an intelligent species beyond our solar system — and he shows no signs of retreating from that possibility.

Observations led Loeb and his colleagues to an intriguing — if admittedly far-fetched — question: could the mysterious object be generating its own light?

After discussing the data with fellow Harvard astrophysicist Eric Keto, Loeb proposed that the “simplest interpretation” of 3I/ATLAS’s unusually “steep brightness profile” is that its nucleus “produces most of the light.”

If true, that would imply the object is much smaller than currently estimated, putting it closer in scale to the first two interstellar objects ever observed, ’Oumuamua and 2I/Borisov.

Loeb floated two possibilities: either 3I/ATLAS is naturally emitting radiation because it is a “rare fragment from the core of a nearby supernova rich in radioactive material,” or it is a “nuclear-powered spacecraft, with the dust emitted from its leading surface being debris collected during interstellar travel.”

He considered the first scenario “highly unlikely,” and said the second would “require better evidence to be viable.”

Loeb has also argued that the object’s unusual trajectory — including conspicuously close passes by both Earth and Jupiter — and its lack of a visible tail challenge the idea that it’s simply a comet.

Interestingly, 3I/ATLAS is expected to pass extremely close to Mars this fall, offering a rare chance for direct observation. Loeb has suggested using NASA’s Mars Reconnaissance Orbiter to aim its instruments at

Editors Comment

3I/ATLAS is a remarkable object — not because it is alien, but because it offers researchers another rare opportunity to study material from beyond our solar system.

That alone is extraordinary. Turning it into the centerpiece of a conspiracy does not enhance the wonder of the universe; it obscures it.
