NASA announced that new data proves that Voyager 1 has officially reached interstellar space, becoming the first man-made object to leave our solar system. Voyager 1 has traveled 12 billion miles from the Sun and spent about one year in a transitional zone. Scientists had witnessed two of the three indicators that the spacecraft had left our system—cosmic rays from the outside and the disappearance of charged particles. They were waiting for the change in the magnetic field to confirm the leap but the wait took longer than they expected. They say the data now shows that Voyager 1 actually left our Solar System back in August 2012.
