Harvard physicist, Dr. Avi Loeb, suggests that the Manhattan-sized interstellar object 31/ATLAS could be an alien probe with potential to cause destruction.

Scientists estimate the object to be more than 12-miles-wide, speeding at 37 miles-per-second, relative to the sun.

"The consequences, should the hypothesis turn out to be correct, could potentially be dire for humanity," said Avi Loeb.
