Our galaxy is hairy.

Well, that's not quite true. It's more filamentary. Like, loaded with strands, filaments, of gas and dust running through it. These can be light years long, though very narrow. They are thought to form as streams of material in a rotating galaxy converge and collide; it's also possible the turbulence created when stars explode helps this process along.
