How does IBEX's data add to what we previously knew?

Previously, our only direct look at the boundary was in two specific locations through data collected by the Voyager 1 and Voyager 2 spacecraft as they encountered this region of space. While data from the Voyager craft give two pinpoint, “weather station” views of the interstellar boundary region, IBEX provides a “weather satellite” view over the whole sky. The IBEX results show that a lot of the action is happening away from the two Voyagers. We would not have discovered this without IBEX!
