For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.

Both spacecraft carry with them a 12-inch (30 cm) golden phonograph record that contains pictures and sounds of Earth, along with symbolic directions on the cover for playing the record and data detailing the location of Earth.[1][18] The record is intended as a combination of a time capsule and an interstellar message to any civilization, alien or far-future human, that may recover either of the Voyagers. The contents of this record were selected by a committee that included Timothy Ferris[18] and was chaired by Carl Sagan.
