Graphic combines one of the possibilities for the bright ribbon of emission seen in the IBEX ENA maps with an image of the IBEX spacecraft. The galactic magnetic field shapes the heliosphere as it drapes over it. The ribbon appears to trace the area where the magnetic field is most parallel to the surface of the heliosphere (the heliopause). Credit: SwRI
