The Sun moves through the local interstellar medium, continuously emitting ionized, supersonic solar wind plasma and carving out a cavity in interstellar space, called the heliosphere. The Interstellar Boundary Explorer (IBEX) spacecraft has just completed the first all-sky maps of the interstellar interaction at the edge of the heliosphere, by imaging energetic neutral atoms (ENAs) emanating from this region. IBEX all-sky maps and energy spectra provide detailed information about the interaction. Our observations show globally distributed fluxes ordered by the solar wind structure, which are superposed by another, unexpected feature, which is neither seen by the Voyager spacecraft nor predicted by any current model or theory. This talk summarizes the IBEX observations, shares our unexpected results, and discusses some of the possible ideas for what may be missing in our current understanding of the heliosphere’s global interaction.
