A mystery object hurtling through space could be emitting a "technological signature" as it heads toward Earth, a boffin fears. Harvard professor Avi Loeb said 3I/Atlas could even clearing the path from any hazardous micrometeorites that could damage it.

Nasa tried to quash claims the interstellar visitor was an alien spacecraft on Wednesday, but Loeb claims the latest pictures show glowing plume in the direction of motion ahead of it.
