The galactic current sheet (GCS) sweeps dust and debris into the Solar System. The 3 interstellar objects, all very recent, may be some of that debris. The idea of panspermia, together with the GCS and its debris, may explain things like the platypus, or jellyfish, etc. Species that are extincted by the end of the cycle get replaced by new species that seemingly pop up out of nowhere. Maybe the really weird ones pop out of the trail left in the cyclical wake of interstellar objects.
"Astronomers using the Very Large Telescope in Chile have made a startling discovery about the mysterious interstellar visitor 3I/ATLAS. New spectroscopic data shows its plume of gas is laced with unusual chemicals, including cyanide and nickel but strangely, no trace of iron. Even more puzzling, the levels of these elements are rising sharply as the object gets closer to the Sun. This is no ordinary comet. Typically, as icy bodies heat up, they release familiar signatures of water vapor, carbon compounds, and metals like iron. But 3I/ATLAS is breaking the rules. The absence of iron, combined with the surge of nickel and toxic cyanide, points to a composition unlike anything we’ve seen in our solar system. Why does this matter? Because 3I/ATLAS didn’t come form here. It comes from another star system, carrying with it the chemical fingerprint of a completely different cosmic neighborhood. Studying it is like analyzing a piece of another stellar system, frozen for eons, and now unraveling under the heat of our Sun. The cyanide emissions in particular raise eyebrows. On Earth, cyanide is deadly—but in interstellar chemistry, it plays a role in forming complex organic molecules. Could 3I/ATLAS be carrying building blocks of life, scattered across the stars? Or is it a fragment of something more exotic, like a shattered planet rich in rare materials?"
