Voyager, 30 years on
Voyager 1 was launched on the 5th September, 1977.
Still operational after 30 years, Voyager 1 is now more than 103.2 astronomical units away from the Sun.
Astronomers believe it has now entered the solar system's heliosheath - the termination shock region between the sun's solar wind and interstellar space.
Signals from Voyager 1 take 13 hours to reach Earth, travelling at the speed of light.
Wired has an excellent slide show of Voyager-related images. Worth a browse.
