IBEX map of the heliosphere

Data from NASA's Interstellar Boundary Explorer (IBEX) enabled scientists to create this map of the complex interactions occurring at the edge of the solar system in the summer of 2009. NASA's Voyager 1 and Voyager 2 spacecraft reached the termination shock in 2004 and 2007, respectively, taking point measurements along their travels out of the solar system. Before IBEX, there was only data from these two points at the edge of the solar system. While exciting and valuable, the data they provided about this region raised more questions than they resolved. IBEX has filled in the entire interaction region, revealing surprising details completely unpredicted by any theories. IBEX completes one all-sky map every six months.
