Voyager 1 was launched in 1977, and for the past 36 years has been trekking across our solar system. NASA confirmed in September that it had finally passed into interstellar space, the first man-made object to do so.

Now about 12 billion miles from our sun, Voyager 1 is still under the influence of the sun's gravity and hasn't technically left the solar system entirely — that could take another several tens of thousands of years. Still, the progress is remarkable and marks the starting point of real deep-space exploration.
