Humanity escapes the solar system
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.

The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. The Voyager spacecrafts are not heading towards any particular star, but Voyager 1 will be within 1.6 light years of the star AC+79 3888 in the Ophiuchus constellation in about 40,000 years.[1]
As the probes are extremely small compared to the vastness of interstellar space, the probability of a space-faring civilization encountering them is very small, especially since the probes will eventually stop emitting any kind of electromagnetic radiation. If they are ever found by an alien species, it will most likely be far in the future as the nearest star on Voyager 1's trajectory will only be reached in 40,000 years.
Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."[2] Thus the record is best seen as a time capsule or a symbolic statement rather than a serious attempt to communicate with extraterrestrial life.
