Voyager 1 is dying. With only two instruments left and its nuclear power fading by four watts every year, humanity's most distant spacecraft will go silent sometime in the early 2030s. Most people think that is the end of the story. It is not even close. When the last signal fades, Voyager 1 will keep moving at 38,000 miles per hour, beginning a journey that will last hundreds of thousands of years, carrying the Golden Record through a darkness no human will ever witness.

This is the full story of where Voyager 1 will die, why that place matters more than you think, and what happens across the 100 trillion miles that come after, from the Oort Cloud to the first stellar flyby to the merger of the Milky Way and Andromeda billions of years from now.

The operating mission is not the main event. It is the first breath.
