SOHO — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
The Sun-watching veteran has guarded against solar storms for three decades and stumbled onto thousands of sungrazing comets along the way.
Cosmoscope draws SOHO on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where SOHO 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.
