Nearly two weeks after the interstellar object 3I/ATLAS passed closest to Earth, a fresh debate has emerged over its true nature. The renewed scrutiny followed a response from the Central Intelligence Agency that has raised new questions about earlier assessments.
The National Aeronautics and Space Administration had previously stated that its research found no evidence of alien technology. NASA classified 3I/ATLAS as a natural comet and ruled out any link to unidentified flying objects.
Despite that conclusion, concerns have persisted in scientific circles. Harvard astrophysicist Avi Loeb has repeatedly challenged NASA’s findings. He pointed to a series of anomalies that, in his view, do not match the behaviour of a typical comet.
🚨 A Comet… or Something More? Why the CIA Went Silent on 3I/ATLAS
NASA says 3I/ATLAS is just a natural comet. Case closed.
But then the CIA did something strange.
On December 31, 2025, the CIA responded to a FOIA request about 3I/ATLAS by saying it could “neither deny nor… pic.twitter.com/kgZBcOKTH5

According to Loeb, the object displayed an unusual anti-tail that appeared to point away from the Sun. He also highlighted unexpected course changes that seemed inconsistent with gravitational laws. In addition, he raised questions about indications of a nickel-rich shell-like structure.
The controversy intensified after a Freedom of Information Act request filed in November 2025 sought records related to 3I/ATLAS. In its reply, the CIA stated that it could neither confirm nor deny the existence of any relevant documents. While such language is standard for intelligence agencies, it often fuels speculation about classified knowledge.
3I/ATLAS made its closest flyby of Earth on December 19, 2025. It is now travelling rapidly toward Jupiter. Scientists expect the object to leave the solar system entirely by 2030.
For now, NASA maintains that the object poses no threat and is consistent with known cosmic phenomena. Still, the CIA’s guarded response and continued scientific debate ensure that 3I/ATLAS remains one of the most closely watched interstellar visitors in recent years.
