"New results from NASA's Interstellar Boundary Explorer (IBEX) reveal that the bow shock, widely accepted by researchers to precede the heliosphere as it plows through tenuous gas and dust from the galaxy, does not exist." - Maria Martinez, SwRI Roadrunner, June 2012 So Voyager must actually be traversing some part of the heliopause rather than the bow shock front as has been reported in the popular press. Even NASA's own website has a story as recently as this spring that, while not specifically mentioning the theorized "bow shock" front, has an image depicting it. However, NASA's IBEX mission reports the solar system's bow shock front is reportedly missing. Hmmm.... curiouser and curiouser!
