The mysterious Oumuamua object that was spotted in the Solar System could be “a lightsail of artificial origin,” according to a Harvard study published earlier this month.
“Considering an artificial origin, one possibility is that ‘Oumuamua is a lightsail, floating in interstellar space as a debris from an advanced technological equipment,” researchers said in the paper (pdf) on Nov. 1. It noted that the object had “peculiar acceleration” through space.
