They are revolutionaries, the first data ever coming to earth from the confines of the solar system , a step away from the big leap into interstellar space. We are sending the historic spacecraft Voyager 1 , launched by NASA in 1977, and are published in Nature show that the theories that have so far described the extreme boundaries of the solar system are not worth more '. The new data sent from Voyager 1 have an entirely new framework of the border area, called the heliopause , where the effect of solar wind ends and interstellar space begins.

These not only indicate that Voyager 1 is now on the verge of leaving the solar system, but contradict the current theories of physics have provided so far, namely that the speed 'of the solar wind, ie the swarm of particles given off by the Sun, does not undergo abrupt changes in the vicinity 'of the heliopause.
There would, in short, a sudden jump in the Solar System and its exterior, but the entrance into interstellar space would be gradual and progressive. Exactly the opposite of when it was believed, namely that there was a sudden and sharp boundary between the warm flow of the solar wind and the cold interstellar medium. Traveling from more 'than 33 years, Voyager 1 and' the first man-made vehicle on the verge of crossing the boundaries of interstellar space and is 'also the most space object' absolute distance from Earth: up to 117 times the distance between Earth and Sun ( Unita 'Astronomy ), over 16 billion miles. Designed to visit Jupiter and Saturn, the probe 'was considered a messenger from the beginning of humanity'. On board it has a gold record called Voyager Golden Record, on which are recorded images and sounds of Earth.
