Voyager 1 was launched on September 5 in 1977. It is the farthest man-made object to Earth.

The Voyager 1 spacecraft is a 733-kilogram robotic space probe of the outer solar system and beyond, launched September 5, 1977, and is currently operational. It visited Jupiter and Saturn and was the first probe to provide detailed images of the moons of these planets.
Voyager 1 is the farthest man-made object from Earth, traveling away from both the Earth and the Sun at a relatively faster speed than any other probe. Though its sister-craft, Voyager 2, was launched 1 month earlier, Voyager 2 will never pass Voyager 1. Neither will the New Horizons mission to Pluto, despite being launched from Earth at a faster speed than both Voyager craft. During its lifetime Voyager 1 has benefited from a number of gravity assisted speed boosts.[1]
As of July 6, 2007, Voyager 1 is over 15.44 terameters (15.44×1012 meters, or 15.44×109 km, 103.2 AU, or 9.6 billion miles) from the Sun, and has thus entered the heliosheath, the termination shock region between the solar system and interstellar space, a vast area where the Sun’s influence gives way to the other bodies in the galaxy. If Voyager 1 is still functioning when it finally passes the heliopause, scientists will get their first direct measurements of the conditions in the interstellar medium.

Currently, light takes 13.8 hours to reach Earth. Compare that to the other planets in our solar system to get an idea of its distance from Earth.

As a basis for comparison, the Moon is about 1.4 light seconds from Earth, the Sun is about 8.5 light minutes away, and Pluto is at an average distance of approximately 5.5 light hours. As of November 2005, the spacecraft was traveling at a speed of 17.2 kilometers per second relative to the sun (3.6 AU per year or 38,400 miles per hour), 10% faster than Voyager 2.

It is now 21 billion kilometers from Earth.  To have something that far off from us and yet being able to communicate with it, gives us humans an amazing opportunity.  To know what is “out there” and if there is any living presence that can be detected physically?  How long can we keep communicating with it, as it keeps going further and further from us?  Here is a very informative video for that.

Voyager 1 is the crowning glory of human adventure and scientific understanding.  It takes our eyes and ears, if you will, beyond our own solar system.

On a side note, as of now, the probe has not encountered anyone ‘sitting’ out there with a banner or note saying “God – ville”.  So such things showed themselves up.  For whatever it is worth.

Voyager 1 is steaming ahead at top speed and will one say Adios and never be seen again.
