Discover what happens at the outer edges of our solar system, where the solar wind interacts with interstellar space. The Interstellar Boundary Explorer (IBEX) is a mission to study the boundary between the solar system and interstellar space. Voyager 1 and 2 have provided some direct measurements from the boundary region; IBEX collects energetic neutral atoms that come from there to create all-sky maps. Information from the particles (such as energy and direction) show the global structure and dynamic nature of the heliosphere and reveal details that challenge current models of how the solar system interacts with the galaxy.
