Voyager 1 recorded plasma music while traveling outside the heliosphere


Space.com reports that Voyager 1 is the farthest manmade object to leave the Solar Sytem. Yes, in a sense we are now an interstellar species. Not in the way I imagined, but it still cool, ok?

How about the music Voyager 1 has detected? Space.com:

Voyager 1’s ‘plasma wave instrument’ detects electrons that are excited when solar storms interact with the ionized gas that surrounds it. They occur at frequencies up to a few thousand hertz, so it can be translated to audio via loudspeakers.

Basically, that means that the plasma makes sure that the electrons on the antennae are moving up and down with a certain frequency and thus this can be interpreted as a “sound”. Pretty neat.
