The space probe Voyager I was launched 30 years ago, and is still operational. Voyager is more than 103 astronomical units away from Earth (an astronomical unit is 93 million miles, so that’s roughly 9.5 billion miles away). Signals from the probe take 13 hours to reach earth, traveling at the speed of light. A Wired slideshow features some of the better images taken from the Voyager program since 1977. This image is a composite of photos of Jupiter and its moons taken in 1979. Link
