Harvard scientist Avi Loeb speculated that NASA’s recently released photos of 3I/ATLAS could potentially point to its artificial origins — and even wondered if the so-called comet was purposely targeting and sweeping meteorites out of its path. He posited his theory in a viral new blog post on Medium.

Harvard scientist Avi Loeb analyses NASA's 3I/ATLAS photos, theorising the comet's forward-facing glow could be alien technology designed to actively clear meteors from its flight path.

A new set of deep-space images has reignited one of the strangest scientific arguments of 2025. The photos show sideways jet-like lines shooting out from the interstellar object 3I/ATLAS. Their geometry is so unusual that Harvard astrophysicist Avi Loeb says they may not be natural at all.

NASA's latest release of imagery for interstellar object 3I/ATLAS has triggered new scientific and public scrutiny as the comet-like visitor moves toward its mid-December flyby of Earth. The agency's 19 November publication of HiRISE camera data,

Harvard astronomer Avi Loeb is still not giving up hope that 3I/ATLAS could be an alien mothership and says it's too early to call it.

NASA’s newly released images of comet 3I/ATLAS, in the solar system since July, sparked backlash online as many criticized the blurry, low-quality photos.

NASA on Wednesday released new images of 3I/ATLAS that agency officials say proves the interstellar object is a comet, albeit an unusual one. But Harvard astrophysicist Avi Loeb says Earthlings won’t definitively know until Dec.

The controversial scientist has once again spoken out about his desire to find little green men aboard 3I/ATLAS.

Avi Loeb says 3I/Atlas is gaining speed as new images show unusual tail changes. We unpack the data, comet physics, and whether it poses any risk.

Harvard astrophysicist Avi Loeb warns that ignoring anomalies linked to interstellar object 3I/ATLAS could cause humanity to overlook potential evidence of alien technology.
