I will do a post on Voyager 1 and 2, twin sister ships another time.
Voyager 1 has made news because after thirty five years of space travel, she is at the point where she will go into interstellar space.
A lot of this is about the unknown. No one knows what is out there in space as Voyager 1 continues to travel. The images show what was known and what was found  not to be the case in the outer region beyond the solar system. It is confusing because we are finding out about the unknown.
All the pictures are from NASA/JPL.

Voyager 1 was launched on September 5, 1977.
