Scientists report that the first object from another star system found speeding through our solar system in 2017 was not an alien spaceship. Astronomers named the cigar-shaped object Oumuamua, but they still do not know exactly what it is. Its strange shape and movements made some scientists wonder whether Oumuamua was some kind of technology from a distant world. They wondered whether alien beings had created the object to explore the universe. But after studying records from the 2017 sighting, an international team of researchers wrote that “we find no compelling evidence to favor an alien explanation.” Scientists followed Oumuamua from October 14, 2017, until January 2, 2018. They raced to collect as much data as possible as it passed through our solar system. Then it became too difficult to see, even using the most powerful telescopes.
