No such thing has been confirmed. The observations of 'Oumuamua showed it exhibited non-gravitational acceleration during its pass through the Solar System which is consistent with solar radiation acting upon a low mass-to-area surface. Making a jump to ALIENS is pure conjecture. https://t.co/hBHt1ikEXa

This link, per Jason Major, is to a draft PDF download of the paper that spurred this discussion. Of course we all want the answer to every cosmic question to be (friendly) aliens, but that low mass-to-area “solar sail” hypothesis is certainly believable, given Oumuamua’s unusual shape.
Original post (and first update)
Oumuamua has been tumbling through interstellar space for a LONG time.
Also, per the reference at that link, it’s apparently red!
Update, July 1, 2018: Huh, that’s weird.
