Mysterious interstellar object 3I/ATLAS has reemerged from behind the Sun, allowing astronomers to once again get a glimpse at the rare visitor. However, to Loeb that’s just one out of two possible scenarios. These jets could also be evidence of “thrusters on a technological spacecraft,” as he told NBC News on Monday. “Technological thrusters which point their exhaust towards the Sun would accelerate away from the Sun,” Loeb noted in his latest blog post. But Loeb isn’t ready to give up hope that we could be looking at an alien spacecraft.
