Episode Synopsis

Not all dark matter is "dark matter" dark matter. Some is simply dark, well, matter. An Australian radio telescope has found a long filament of cold plasma from the scintillations it produces in the radio waves of background sources. We'll explain all that, and take a deep dive into dust from space and dust from your face in another wide-ranging episode of Walkabout the Galaxy.
