Oumuamua, the first interstellar object spotted in the solar system, could very well be an alien spacecraft, two Harvard researchers say.
The size of a stadium, Oumuamua is flat and elongated, and accelerated as it tumbled past the sun. It's very different from the typical asteroid or comet, and in a paper that will be published Nov. 12 in The Astrophysical Journal Letters, Avi Loeb and Shmuel Bialy write that it "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization."
