Voyager 1 Has Left the Solar System

artist's rendition from www.nasa.gov 
Here's something to ponder: Voyager 1 is the first human-made craft to travel beyond the Milky Way solar system. Over 9.5 billion miles away. A distance I cannot begin to comprehend. It is traveling through the heliopause, which, according to the American Heritage Science Dictionary, is "the region surrounding the solar system at which pressure from the interstellar medium (made up mostly of hydrogen and helium), and the solar wind can penetrate no further. It is considered to be the outer boundary of our solar system."

What does this even mean? I apprehend the definition, but am totally awestruck by the scope of what it is describing. Something launched from Earth the same year Apple Computer was incorporated, Rod Stewart's Tonight's the Night (Gonna be Alright) was Billboard's #1 Hit, and Harvey Wallbangers were a popular drink in the discos. Voyager 1 is still going.... leaving us farther and farther behind

What do you think about Voyager 1's adventure?
