    NASA's Voyager 1 is now 11 billion miles from Earth. The spacecraft has entered a new region between our Solar System and interstellar space. The data from Voyager over the past year reveals a new region where the wind of charged particles from Sun has diminished, and particles from inside the solar system seem to be "leaking" out into interstellar space.
