Was it alien space junk?A wandering interstellar asteroid?Or a weird comet from another sun?Ever since 2017, when astronomers in Hawaii discovered an object they called Oumuamua (Hawaiian for scout) zipping through the solar system, they have been arguing about what it was.Telescopes saw only a tumbling dot that was already on its way back out into the interstellar dark.
