Many years ago, NASA’s Voyager 1 left Earth. And now, on a recent star trek, the craft departed our solar system, moved past cosmic purgatory (a real thing), entered interstellar space, and brought home supernatural sounds of the beyond (cue Twilight Zone music).
How did Voyager 1 hear this deep, dark area of space? Via plasma! While traveling through the space between the stars, Voyager 1 recorded vibrations made by the very, very dense plasma of interstellar space, and sent back to Earth the very first recordings of the sound caused by this über-dense ionized gas, which you can hear for yourself in the video below:
To celebrate this grand achievement. 2 TEDx Talks on the wonders of space exploration:
Tour the solar system from home: Jon Nguyen at TEDxSanDiego
Not all of us can board a spacecraft to tour the universe. At TEDxSanDiego, NASA engineer Jon Nguyen demos NASA’s "Eyes on the Solar System" software — a free-to-use program that allows users to navigate our solar system without ever having to leave home. Look out for a Voyager 1 cameo at the 5-minute mark.
A sense of place from space: Joseph P. Allen at TEDxSonomaCountry.
