"I'm not saying it's an alien technology," Loeb said. "I'm just saying it doesn't look like a very common thing, and actually, the glow that is around this object, usually for comets, you see a trailing tail behind the object and here the glow from the Hubble Space Telescope image is actually in front of the object.
