Earth — planet, shown live in Cosmoscope, a real-time 3D map of the universe.
The only known world with liquid-water oceans at its surface — and the only one known to harbor life. The terminator you see here is real: this is where sunrise and sunset are happening right now.
Cosmoscope puts Earth 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 Earth 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 Earth where it was on any past date, or where it will be years from now.
