Oumuamua (also known as 1I/2017 U1) is a small, rocky object that was discovered in 2017 by the Pan-STARRS telescope in Hawaii. It was initially classified as a comet, but later reclassified as an asteroid. Oumuamua is unusual in that it appears to have come from outside of our solar system, making it the first known object of its kind.
There has been some debate among scientists about the nature of `Oumuamua and its origins. Some scientists have suggested that it could be a piece of alien technology, while others have proposed more mundane explanations, such as that it is a natural asteroid that was ejected from its home system by a gravitational interaction with a larger body.
Overall, the scientific community remains divided on the nature of `Oumuamua and more research is needed to understand its true origins. However, most scientists believe that it is likely a natural object, rather than being of extraterrestrial origin.
