Insecure border in the form of galactic cosmic rays


The detection advise that the defensive border that separate our solar system from the rest of the galaxy lack the bow shock, because confirmed in the current scientific theories and could have implication on how much radiation (in the form of galactic cosmic rays) enters our solar system. For about a quarter of a century, researchers believed that the heliosphere is moving through the interstellar medium at a rate fast enough to form a bow shock. However, IBEX data have shown that the heliosphere actually moves through the local interstellar cloud at 83,685 kilometers per hour, about 11,200 kilometers an hour slower than previously thought. The bow shock would ionize gas or plasma changes abruptly and discontinuously in density in the region of space that is ahead of the heliosphere.
