Voyager 1 — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
Launched in 1977 with a golden record of Earth’s sounds, Voyager 1 crossed into interstellar space in 2012. Its faint signal now takes nearly a full day to reach home.
Cosmoscope draws Voyager 1 on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Voyager 1 is right now, how far it has travelled from the Sun, and how long its radio signal takes to reach Earth. Scrub the timeline to replay the route that took it there.
