Space Oddities: Bye Bye Bow Shock, HMOs, Binaries, Tyche, Local Fluff, Etc.

Full Story from New Interstellar Boundary Explorer data show heliosphere's long-theorized bow shock does not exist

New data from the IBEX spacecraft show that the heliosphere’s lower speed, combined with higher magnetic pressures found in the interstellar medium, prevent the formation of a bow shock, which for decades was thought to form ahead of the heliosphere as it moved through the galaxy. Instead, these factors combine to suggest the heliosphere creates more of a bow “wave” as it travels through space. Credit: Southwest Research Institute
