All Things Space, UFOs, etc.Interstellar object caught emitting mysterious metal that suggests ‘technological origin’ Posted on September 2, 2025 by Administrator An interstellar object speeding through our Solar System has been spotted spewing a metal unlike anything seen in natural comets. The Very Large Telescope (VLT) in Chile detected an unusual nickel plume from the object, known as 3I/ATLAS. Unlike natural comets, which always emit nickel alongside iron, 3I/ATLAS shows the metallic element without any detectable iron. Harvard physicist Avi Loeb highlighted the anomaly described in a new study, noting that this nickel signature is a hallmark of industrial production of nickel alloys.
