This is the furthest distance any man-made object has ever travelled - and on July 28th, it's long and arduous journey was broken by cosmic changes.
The data received from the Voyager, which travels at six miles an hour, on July 28th showed a five per cent spike in the level of high-energy cosmic rays.
This implies the Voyager is moving out of the heliosheath - the 'protective bubble' around the solar system created from charged particles from the sun. Read More
