NASA has announced that the first human-made object left the confines of our solar system a year ago. It is now traveling beyond the heliosphere, or sphere of our sun’s influence. NASA made the announcement on September 12, 2013 that the Voyager 1 spacecraft – launched from Earth in 1977 – has now officially entered interstellar space. NASA also released this video, in which the sounds of interstellar space can be heard. In fact, the science team used these sounds to help determine the density of space through which Voyager 1 is now passing.

The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

Bottom line: Sounds of interstellar space, from the amazing Voyager 1 spacecraft.
