Instruments on board NASA's Voyager 1 spacecraft, which nine years ago left our solar system's outer reaches, have picked up the faint, monotonous sound. These vibrations, called persistent plasma waves, were identified at radio frequencies in a narrow bandwidth during a three-year period as Voyager 1 travels interstellar space. The new study reveals steady vibrations unrelated to solar activity that could be a constant feature in interstellar space. "There are conceptual designs being made for future probes whose intended purpose is to reach further than the Voyager spacecraft.
