Voyager 1 Nears Edge of Heliosphere

With absolutely no attempt at hyperbole at all, it is fair to say that this is one of - if not the - biggest achievement of the human race.

For, as we speak, an object conceived in the human mind, and built by our tools, and launched from our planet, is sailing out of the further depths of our solar system - and will be the first object made by man to sail out into interstellar space.

The Voyager 1, built by Nasa and launched in 1977 has spent the last 35 years steadily increasing its distance from Earth, and is now now 17,970,000,000km - or 11,100,000,000miles - away, travelling at 10km a second.

Indications over the last week implies that Voyager 1 is now leaving the heliosphere - the last vestige of this solar system.
