New data from NASA’s Voyager 1 that was launched in space in 1977, indicates the probe has left the Solar System boundary, the influence of the Sun’s bubble of charged particles and entered true interstellar space, after a 36-year odyssey through the Solar System, across more than 11,253,000,000 miles.

Voyager 1 has become the first man-made spacecraft to venture into interstellar space, according to Nasa scientists. They say new data shows the probe has already been traveling through a transitional region outside a solar bubble for around a year.
NASA’s Voyager 1 captures sounds of interstellar space
Scientists managed to work that out after an eruption from the Sun reached Voyager 1 and caused the plasma around it to react in a way that could be sensed.
Plasma outside the so-called heliosphere, which is caused by the Sun’s effects, is more dense and so the vibrations produce deeper sounds.
That led NASA to the conclusion that the probe had entered interstellar space.
Each Voyager (1 and 2) space probe carries a gold-plated audio-visual disc in the event that either spacecraft is ever found by intelligent life forms from other planetary systems.The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from people such as the Secretary-General of the United Nations and the President of the United States and a medley, “Sounds of Earth,” that includes the sounds of whales, a baby crying, waves breaking on a shore, and a collection of music, including works by Mozart, Blind Willie Johnson, Chuck Berry’s “Johnny B. Goode”, Valya Balkanska and other Eastern and Western classics and ethnic performers.
