Oumuamua, the first interstellar object discovered in the solar system, has sparked renewed interest in how to distinguish between natural objects and possible technological signatures. The new study highlights that most of the solar system has not yet been scanned at sufficient resolution to definitively rule out small artificial objects. Credit: NASA, ESA, and J. Olmsted and F.
