Voyager 1 is about to reach a distance of one light-day from Earth, marking a cosmic milestone as it ventures deeper into interstellar space with fresh discoveries about the solar system's edge.
·Voyager 1 nears one light-day distance from Earth, revealing new data about the heliopause boundary
·Voyager 2 plasma observations show the heliopause and interstellar medium interaction raising new questions
·NASA is mapping the true shape of the solar system's outer wall
·Both probes continue transmitting stunning discoveries from the edge of our solar system
·Voyager missions demonstrate a route for leaving the solar system altogether
