Robot Spider Alien Hoax Spreads Across Social Media

In a striking example of social media misinformation, a fabricated story about alien robotic spiders discovered in Antarctica has been circulating on Facebook since October 2025, prompting numerous inquiries from concerned individuals.

The widely shared post claimed scientists had found microscopic robotic spiders of extraterrestrial origin on Earth’s polar ice sheets, allegedly detached from interstellar comet 3I/ATLAS during its closest approach to our planet. According to the false narrative, these mechanical arachnids were collecting data from Antarctic ice and transmitting it to deep space.

A thorough investigation revealed no credible evidence supporting any element of this story. Despite the post describing the purported discovery as “sending global shockwaves,” not a single legitimate news outlet, scientific publication, or research institution has reported such a finding. The complete absence of corroborating sources beyond social media strongly indicates the fabricated nature of this claim.

Further examination exposed multiple factual inconsistencies that definitively debunk the story. The Facebook post stated that the mechanical spiders detached from 3I/ATLAS during its closest approach to Earth—an event that hasn’t actually occurred yet. According to the European Space Agency, the comet’s closest approach to our planet is scheduled for December 19, 2025, nearly two months after the post first appeared.

NASA tracking data provides additional contradictory evidence. Animations produced by the space agency show that the sun has been positioned between Earth and 3I/ATLAS for much of the period since the comet’s discovery, making any supposed detachment and landing on Earth physically impossible under the timeline proposed.

The image accompanying the posts contained several telltale signs of digital manipulation or AI generation. Despite claiming to show Antarctica, the northern lights are clearly visible in the upper portion of the image—an astronomical impossibility since auroras occur near the respective magnetic poles and are not visible across both hemispheres simultaneously. The alleged “spiders” depicted in the image show inconsistent anatomy, with varying numbers of legs, and the closeup inset differs significantly from the specimens shown in the wider shot.

The source of the misinformation appears to be a Facebook page called “Space Lane,” which has a documented history of publishing fabricated extraterrestrial stories. The page frequently posts sensationalist content about supposed alien contact, often referencing 3I/ATLAS, which is indeed a genuine interstellar comet discovered in 2025.

This isn’t the first time claims about 3I/ATLAS have been subject to fact-checking. Previous viral misinformation suggested the comet was “most likely” an alien spacecraft heading toward Earth—a claim also thoroughly debunked.

Interstellar comet 3I/ATLAS has garnered significant scientific interest as one of the few observed objects to enter our solar system from elsewhere in the galaxy. Like ‘Oumuamua before it, the comet provides astronomers with rare opportunities to study material formed around other stars. However, legitimate scientific discussion about the comet focuses on its composition, trajectory, and origin—not unfounded claims about robotic spiders.

Social media platforms continue to struggle with the proliferation of science-related misinformation. Posts like these exploit public fascination with space exploration and potential extraterrestrial life, often generating significant engagement despite their fictional nature. The episode serves as a reminder of the importance of consulting established scientific sources when encountering extraordinary claims online.
