Voyager 1 and Voyager 2 are now in the most outer area of our solar system, where to our knowledge no man made machine or humans ever been. Voyager 1 and Voyager 2 was sent out to space by NASA in 1977. Since then, 34 years ago, it have been sending incredible images and information back to earth. The last information it sent took some 16 hours + to reach our earth.
Soon, very soon V1 and V2 will continue traveling OUT of our solar system.
Read that once again - they will travel across the border of our solar system.
And no one knows exactly what will happen to V1 and V2 or what they will meet. This is in my view one of the most exciting things going on right now.
