It all started in the early 1990s, when the mystery of our universe was revealed through Hubble’s newly functioning lenses penetrating the cosmic veil. Weird outliers, like dim, rapidly moving dots that didn’t fit the usual description, appeared among the brilliant nebulae and galaxies.

At first, these objects were thought to be simple space trash or observational mistakes. However, as they kept multiplying and getting closer to our solar neighborhood, NASA secretly became concerned.

The evidence has grown indisputable as the years passed into decades.
