interplanetary probe Voyager 1 was the first man-made object has left the solar system – said the U.S. National Aeronautics and Space Administration (NASA).
interstellar space but there is no clearly demarcated boundary and NASA has only recently obtained evidence that the probe was outside the range of a continuous stream of particles emitted by the Sun Elementary – that defeats the so-called heliopause. According to the measurements on-board instruments it happened around August 25 last year.
addition heliopause electromagnetic interaction sun is balanced by the influence of other stars. Does not apply to the gravitational field.
Voyager 1, which embarked on a cosmic journey 5 September 1977 year is currently about 19 billion miles from Earth. To overcome this distance radio waves require more than 17 hours. Nuclear is a thermocouple probe apparatus to sustain operation for about 2025 years.
Voyager 2, which launched less than two weeks before his namesake identical and also continues to send signals away from Earth now 15 billion kilometers. The main mission was to investigate the two probes of Jupiter, Saturn, Uranus and Neptune, which have carried out until 1989. Just like the sun, will now circulate around the center of our galaxy orbits the circulation time calculated in millions of years. In the event of a possible encounter with an extraterrestrial civilization, they were provided with plates of visual resource of information about our planet and its inhabitants.
