Oumuamua

`Oumuamua` is the first detected interstellar object passing through our solar system, identified in 2017. Its unusual shape—elongated like a cigar—and rapid, non-gravitational acceleration puzzled scientists. While some suggested it might be a natural asteroid or comet, others speculated it could be an artificial object, like an alien probe. However, the prevailing view is that it’s a rocky or icy fragment from another star system, providing valuable insights into objects from outside our solar neighborhood. Its discovery highlights the importance of monitoring space for interstellar visitors and enhances our understanding of the diversity of objects traveling through space.
