The Voyager 1 was a very exciting project by NASA that has paid big dividends. The images that it has captured has given us so much knowledge over the years. There is still more to come.
The Voyager 1 will be the first ever manmade object to go beyond the Sun's sphere of influence. The heliopause is the region that Voyager 1 will cover in the next two years before moving out into the Milky Way. It will be interesting to see what information Voyager 1 can send back to Earth after having done that.
