energetic neutral atom emission

Full sky image of the energetic neutral atom emission from the sheath of hot particles formed in the region where the solar wind collides with the interstellar medium (the heliosheath).  The data are shown in galactic coordinates.  The emissions are weak in the vicinity of the galactic poles, which suggests that the interstellar magnetic field is strongly influencing the distribution of the hot charged particles in the heliosheath.
