Voyager 1 Captures Sound in Interstellar Space

For all those who have looked up at the stars and wept, crying “I WILL NEVER KNOW THE SWEET MELODIES OF INTERSTELLAR SPACE” to the silent heavens, relief has come from the sky at long last. After 35 years of space flight, Voyager 1 was the first craft to ever leave our solar system as of August, 2012. Now, in celebration of this feat, Nasa has released a recording of interstellar sound produced by the vibration of dense plasma. This plasma vibrated in increasing tones, telling scientists that it was increasing in density. Via Wired:

Voyager 1′s plasma sensor broke in 1980, so scientists had to get creative, and a little lucky, to figure this out. A massive solar eruption in March 2012 arrived at the location of Voyager 1 about 13 months later, making the plasma around the probe vibrate, NASA officials said.

That vibration helped researchers understand the density of the plasma, determining that it was 40 times more dense than measurements taken in the outer layer of the heliosphere, the bubble of charged particles and magnetic fields that the sun puffs out around itself.

The ramifications of this discovery are still being determined as the Voyager team analyzes the data that the vessel continues to send. Each recording takes about 17 hours to travel from Voyager to Earth, a remarkable feat considering the craft is 12 billion miles from our sun. Nasa researchers are hopeful that, in time, these sound clips will help us understand the far outer reaches of space. Check out the recording, and some information provided by the Voyager team, below.
