Tracked daily by the giant antenna dishes of the Canberra Deep Space Communication Complex (managed on NASA behalf by the CSIRO), the Voyager spacecraft are now departing the Solar System and headed into interstellar space for the first time.
Voyager 1 and its twin, Voyager 2, have been speeding through the outer reaches of our solar system and sending back unprecedented data about the bubble of charged particles around our sun. Launched in 1977, the Voyager spacecraft are the most distant human-made object in space.
The Sun generates a bubble around our solar system. A bow wave is produced as the solar system travels through the galaxy.
