The Voyager 1 spacecraft over 14.7 billion miles from
  Earth at the limit of the 'Heliosheath', where particles
  streaming from the sun hit the gases of the Milky Way
  galaxy. Launched in 1977, Voyager 1 photographed
  active volcanoes on moon Io past Jupiter (1979), and
  discovered 3 new moons by Saturn. Its final photo
  shows Earth as a grainy speck bathed in rainbow rays
  of our Sun (1990). (SA Jun 15,2011)
