The Halloween season is upon us once again. (Finally!)
So yes, we're about to take on the challenge of linking frequency control to Halloween. Can it be done? Maybe. Will it be done? Yes. (We never let the word "impossible" stop us in the past.)
In this post, you're going to discover the dark, creepy side of frequency control by listening to some of the scariest sounds that can be found in outer space.
It's a fairly well-known fact that sound can't travel through space. Space is a giant vacuum, and sound can't travel through vacuums. So how can we hear the dark sounds found within our universe?
A scientific process called data sonification is used on various satellites and spacecrafts to convert radio, microwave, x-ray, and other frequency waves into audio that humans can hear.
Let's start with some of the sounds emitted by our own planet. These plasma wave sounds were captured in Earth's atmosphere by NASA's radiation belt storm probes. This type of plasma wave is called chorus and is created when electrons are pushed towards the night side of Earth — which in some cases may be caused by magnetic reconnection, a dynamic explosion of tangled magnetic field lines on the dark side of Earth.
No, this isn't Darth Vader that you hear. Some scientists think this plasmaspheric hiss is caused by the electrical discharge of lightning strikes on earth. Hiss waves are key shapers of the near-Earth environment, including the Van Allen radiation belts, doughnut-shaped rings of high-energy particles that encircle the planet.
If you've been following Bliley Technologies, you may know that one of our space crystals was used on NASA's Cassini mission around Saturn to allow for the sending and receiving of data, images, and video during the mission.
Saturn is a source of intense radio emissions. Cassini captured some of these awesome frequencies, which were converted to the sound you hear above. It's crazy to think that this data was sent back to earth from Saturn through our crystal!
Are Saturn's radio emissions sounds not scary enough for you? Give the radio sounds of Jupiter's largest moon, Ganymede, a listen. This radio emission data was captured by the Galileo spacecraft, and it kind of sounds like alien life communicating. Are you sure you looked at this closely enough, NASA?
Yes, we can even hear black holes. Black holes are one of the most amazing wonders of our universe. Take a listen above to what actual x-rays from a black hole sound like. Eerie, right?
We hope you enjoyed listening to these scary sounds from space! It's pretty amazing that we can hear these creepy radio frequencies from millions of miles away.
