NASA's intrepid Voyager 2 probe crosses into interstellar space

Data from instruments aboard the spacecraft showed it crossed the outer edge of the heliosphere, a protective bubble of particles and magnetic fields produced by the sun, on Nov. 5, the U.S. space agency said.The boundary crossed by the intrepid probe as it journeys a bit more than 11 billion miles (18 billion km) from Earth is called the heliopause, a place where the hot solar wind runs up against the interstellar medium, the soup of stuff residing between the stars of our Milky Way galaxy."Thi
