The sequence depicts the environment immediately around the central, rotating pulsar. The twin beams demonstrate the rotation of the neutron star which is surrounded by the equitorial wind (shaded red). As the observer pulls away from the pulsar, first the "inner knot" appears from the upper left, then followed by the "sprite", and finally, the jets which appear on opposing sides of the pulsar.
