Microscopic remnants from what could be an unidentified space object that crashed into the Pacific Ocean about a decade ago have been found - and a Harvard scientist hopes they are proof of an advanced alien civilization.
Harvard Professor Avi Loeb and his team went on a 'historic expedition' and managed to collect 50 microscopic particle spherules that look like specs of dust, weighing in a collective 35 milligrams off the coast of Papua New Guinea.
Loeb noticed a "runaway fireball" in 2014 that has exploded in the lower atmosphere and fallen into the ocean.
