Is this interstellar object a sign of alien life?

Technology Nov 24, 2025

An interstellar object called 3I/ATLAS is about to pass relatively close to Earth before heading toward Jupiter.
What makes it interesting? Harvard's Avi Loeb thinks its odd acceleration could be the result of alien technology at work.
As it nears Jupiter, Loeb suggests it might be seeding the planet with technological devices.

NASA vs. the alien theory

NASA says 3I/ATLAS is just a comet made of ice and dust, with its path shaped by sunlight.
But Loeb isn't convinced—he believes something more advanced could be steering it.
This disagreement has sparked fresh debates among astronomers about whether we're seeing natural space stuff or something much stranger.
