A. Symphonies of the planets: NASA Voyager recordings - a series of recordings (5 volumes) that was created from original Voyager recordings. Although space is a virtual vacuum, the sounds were created through the conversion of electronic vibrations. The specially designed instruments on board the Voyagers performed special experiments to pick up and record these vibrations, all within the range of human hearing. The recordings come from a variety of different sound environments and are listed as follows : 1.From the interaction of the solar wind with the planet's magnetosphere, which releases charged ionic particles within a vibration frequency in an audible range (20 - 20,000 Hz). 2.From the magnetosphere itself. 3.From the trapped radio waves bouncing between the planet and the inner surface of its atmosphere. 4.Electromagnetic field noise within space itself. 5.From charged particle interactions of the planet, its moons, and the solar wind. 6.From charged particle emissions from the rings of certain planets. B. Voyager 1, launched on Sept. 5, 1977, has already become the most distant of all human-made objects. Every day, it flies another million miles (1.6 million kilometers) farther from the Sun. Voyager 2 is about 80 percent as far away as its twin. <a href="https://www.last.fm/music/Sound+Effects">Read more on Last.fm</a>.
