Episode overview

Patrick Moore discusses with Professor Samuel Tolansky a startling new theory about an 'invisible' star in the two-star system Epsilon Aurigae. Could this mysterious object be, not an ordinary star at all, but a 'collapsar' or collapsed star within a black hole moving through the galaxy?
