Voyager 1 is the farthest thing humans have ever made. It launched in 1977, flew past Jupiter and Saturn, and has been heading out of the solar system ever since.
In 1990, from 6 billion km away, it turned around and took a photo of Earth: a pale blue dot, smaller than a pixel. Everyone who has ever lived was on it.
In 2012 it crossed the edge of the Sun's bubble of wind, becoming the first spacecraft in interstellar space.
Around November 2026 it becomes the first spacecraft one full light-day from Earth. A message to it takes a day to arrive, and the reply takes another.
It carries a golden record with sounds and pictures of Earth, in case anyone ever finds it.
