I have always been fascinated with our universe with all its mysteries and wonders. So like many other space geeks, I was excited to learn that NASA received confirmation that the Voyager 1 Spacecraft has finally reached interstellar space. After 35 years of space flight, Voyager 1 left our solar system around August 25th 2012.
Even more sensational news was that we now know what interstellar space sounds like. NASA has advised the sounds are produced by the vibration of dense plasma, or ionized gases which were captured by the probe’s plasma wave instrument.
The principle investigator for the Voyager plasma wave investigation Don Gurnett stated “When you hear this recording, please recognize that this is an historic event. It’s the first time that we’ve ever made a recording of sounds in interstellar space”.
Voyager 1 launched on Sept. 5, 1977, about two weeks after its twin Voyager 2 was launched. The two spacecraft toured our solar system, taking close-up looks at the Jupiter, Saturn, Uranus and Neptune systems. Their original mission ended in 1989, but the probes continued to explore the outer reaches of the solar system.
NASA and the Voyager team still communicates with the two spacecraft every day, but the probes’ extreme distances pose a challenge. At the speed of light, it takes about 17 hours for a message to reach Earth from Voyager 1, which is currently about 12 billion miles (19 billion kilometers) from the sun. For many of us this is absolutely remarkable.
Take a listen to the eerie high pitch sounds of interstellar space recorded by Voyager 1 below.

When I was little I wanted to be an astronaut. I loved Star Trek and the idea of exploring the universe in a massive ship with me as the Captain but I wasn’t good at math so I decided to be President of the United States instead. I never really had high hopes for myself. 😉 That is very cool to hear I wish they’d had the technology to have had a video camera sending back live video from it. But 1977 wasn’t there yet.
I am there with you. Voyager was able to take pics as it left the solar system which were very thought provoking for me. So let’s hope we get a pic of interstellar space soon…for some reason I think will be nothing but black fuzz.
I’ve always had this vision that when I die, and am a spirit, that I will leave earth to explore space. I’ve always been interested in space, in exploring it to see just how deep it goes and what lies beyond it. This was very interesting!
@jeremylcarter I very much believe in energy transference so I think it’s possible that when you die the energy that powers you will vibrate throughout the world and possibly throughout the cosmos,just as i think the vibrations and gravitational forces of the universe effect us here on earth,however subtly
YES. I like to imagine myself as the blue dude from the “Watchman”… Dr Manhattan. Be able to think yourself to Mars.
I already spend half the night stargazing,and now that is probably going to increase
While on vacation I recently saw the Milky Way for the first time with my naked eye. It was amazing. Usually can’t see it because of the lights from the city.
