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 image is shown in a similar coordinate system to that used to display the just-released data from the IBEX mission. The two instruments, one near Earth and the other orbiting Saturn, see very similar images, even though the data from the Cassini instrument is at somewhat higher energy than that from the IBEX instrument.
