Voyager data suggests solar system is squashed

Los Angeles Times : The shell of solar gases that encircles our star system has been dinged up by passing through the rubble of stars that exploded millions of years ago say researchers at the annual meeting of the American Geophysical Union in San Francisco.The data is from the 30-year-old Voyager 2 spacecraft that just passed through what’s known as the termination shock, the boundary of the bubble of energy carried by the solar wind to the far edge of the solar system. Voyager 2 reached the barrier a billion miles closer to the sun than Voyager 1, its companion spacecraft that is taking a more southern path to interstellar space.
