Europa — moon orbiting Jupiter, shown live in Cosmoscope, a real-time 3D map of the universe.
Beneath a cracked shell of ice lies twice as much liquid water as all Earth’s oceans — one of the most promising places to look for life.
Cosmoscope puts Europa at its true position in the solar system, computed from JPL-derived ephemeris and updated continuously. Open the live 3D view to see, in real time, how far Europa is from the Sun and from Earth right now, how many minutes or hours light takes to cross that gap, and how fast it is moving along its orbit. Scrub the timeline to place Europa where it was on any past date, or where it will be years from now.
