Heliosphere's long-theorized bow shock does not exist

  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. Stars travel through the galaxy surrounded by a bubble of charged gas and magnetic fields, rounded at the front [continue reading]
