IC 2184 is remarkable, having an aligned filament looking along our line of sight. Stars form inside filaments. Filaments can stretch for billions of light years in length. ESO/HUBBLE & NASA say that IC 2184 is "two interacting galaxies." This is arbitrary to the proof that hundreds of closely packed galaxies are seen in a vortex state, connected together like beads on strings by filaments, beneath the V shaped location where two filaments intersect.
