3I/ATLAS Accelerates on Its Own — Avi Loeb Says an 'Engine' Can't Be Ruled Out

Astronomers detect unexplained acceleration in interstellar object 3I/ATLAS as Avi Loeb suggests an artificial 'engine' can't yet be ruled out.

3I/ATLAS's strange behavior challenges what astronomers know about comets

This is only the third interstellar comet scientists have observed. Its extreme brightening, unusual composition, and intense gas activity offer a rare glimpse into materials and behaviors from outside our solar system, and a reminder that the universe is full of surprises.
