These eerie space ‘sounds’ recorded by NASA are creepy enough to make your skin crawl

NASA – Release of Set of Eerie Recordings of Sound from Space

Sky-high to the pits of our universe, magnanimous spacecraft tend to journey the universe, snapping images of astronomic wonders and some of the spacecraft tend to have instruments, with the potential of capturing radio emissions. When the scientists have the possibility of changing these to sound waves the consequences seem to be strange to hear.

NASA has released a set of eerie recordings of sound from space wherein the set of auto files can be accessed through SoundCloud. From the space agency a statement read thus `Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders. Some spaceships have devices capable of capturing radio emissions. When scientists alter these to sound waves, the results are eerie to hear.

Space scientists at NASA at times tend to take signals from beyond the mortal realm of human senses inclusive of radio waves, plasma waves as well as magnetic fields converting them into audio tracks. This smart hack is known as data sonification which helps the researchers `hear’ what tends to go on with their far-flung spacecraft around planets, comets, moons together with the other locations. The consequences often tend to be ear-splitting though at times the audio seems to be scary.

Accumulation of Out-Space Sounds 


The space agency at NASA had mentioned in a release that they have put together an accumulation of 22 outer-space sounds elusive `sounds’ of howling planets and whistling helium which is sure to make your skin crawl. The following are some of the spookiest tract and what they tend to represent:
Juno Crossing Jupiter’s Bow Shock

The First Juno Crossing Jupiter’s Bow Shock is said to be the sound of the spacecraft of NASA moving across the gas giant’s magnetic field where the whistling sound tends to turn abruptly into a deeper boom as the Juno passes from an atmosphere controlled by solar wind to the magnetosphere of Jupiter. Juno of NASA searched around Jupiter every few weeks at a speed of around 130,000 mph working through all types of invisible fields in the progression.

It is said that one of the toughest undetected signals encountered by the robot was Jupiter’s bow shock, the point wherein the magnetic field of the planet pushes back against the howling wind of incoming particles from the sun giving rise to something similar to a sonic boom. The said audio is considered to be about two hours’ substance of electric field signal compressed into few seconds which seems unnerving.

Stardust Passing Comet Tempel 1

It is a recording of a comet flyby in 2011. The Stardust spacecraft of NASA had been bombarded with dust particles from the comet and the is what can be heard in the recording. The spacecraft had been hit by about 5,000 bits of rock, ice and dust, over a period of 11 minutes.

It is said to be one of the few true audio-like recordings from space wherein the sound is the result of the Stardust spacecraft passing through the dust of comet Tempel 1, ringing the body of the robot with debris.

Cassini Saturn Radio Emissions # 1 

The nuclear-powered Cassini spacecraft of NASA had spent 13 years traveling around Saturn and its system of possibly habitable moons. The Radio Emission of Saturn had been recorded with the Cassini spacecraft when it had recently plunged in the atmosphere of the planet bringing about the long mission to an end.

Saturn is said to be a source of intense radio emission which are related to the auroras of the planet near its poles. The said audio track which tends to be scary is actually radio waves that are emanated by the giant planet through an incidence similar to the once which tends to cause auroras on Earth.

NASA’s Polar Satellite – Plasmaspheric Hiss 

The Earth is said to be encircled in plasma, hot, ionized constituent parts created by sunlight crashing in the atmosphere. The Polar mission of NASA that was launched in 1996 had recorded this breath-like hiss of the plasma when it had orbited the planet.

Out beyond the plasmasphere, where the plasma tend to be shaky and comparatively warm, whistler mode waves seem to produce mostly rising chirps similar to a flock of noisy birds and this kind of wave is known as chorus. The same is created when electrons tend to be pushed towards the night area of the Earth which in some instances could be the result of magnetic reconnections.

It could be a dynamic explosion of jumbled magnetic field lines towards the dark area of the Earth. They tend to interact with particles in the plasma, imparting their energy, creating a exclusive rising tone when these low energy electrons hit the plasma.

Jupiter’s Largest Moon Ganymede – Beware 

NASA has not mentioned which spacecraft had recorded these weird radio emissions from the largest moon Ganymede of Jupiter though there was a possibility of the Galileo spacecraft that had orbited the system for around eight years. Irrespective of what the case may be, changing the data into audio tends to make it sound like screams trying to break through from an unearthly plane.

The Mystery of Space Roar


ARCADE – Scientific Instrument Package Sent in Space – Helium Balloon

Early in July 2006, ARCADE – Absolute Radiometer for Cosmology, Astrophysics and Diffuse Emission, a scientific instrument package had been sent in the air through a Helium Balloon. Columbia Scientific Balloon Facility of NASA in Palestine Texas had been the point of launch and had reached an altitude of 120,123 feet at the point one would call `Space. A research scientist at NASA’s Goddard Space Flight Centre, Dr Alan Kogurt who was also the head of the ARCADE team had been looking for unusual Radio Emission which are rather challenging to monitor on ground level due to the increased Radio noise found on the ground.

 The radio emissions stemming from space has been known since the discovery by Nikola Tesla and probably Karl Jansky. It is said that there is a fragment and uniform radio emission which is believed to have been the result of the Big Bang, Cosmic Background Radiation. Dr Kogurt had been hoping to find confirmation of the Cosmic Background as well as a few new radio emission points and what he found was one of those historic `Wow Moments’ in his scientific research. What he has learned is noted in his own words `The universe really threw us a curve’. Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted’

NASA Discovered `Space Roar’

NASA found something known as `Space Roar’ which is a sound that is six times louder than anything one could have ever expected. It is a signal that has been discovered by NASA’s ARCADE instrument that is presently without any explanation.

In space no one could hear you scream since there is no medium through which sound can move. Space roar is not actually a sound but it is radio waves. Space roar had first been discovered by ARCADE and has a very fancy name for some very fancy equipment which NASA had attached to a big balloon which was sent into space. ARCADE had intended to look for radio signals from distant galaxies.

Since radio is so commonly used and also utilised in creating auditory signals, it seems easy to overlook that it is just another form of light. It is much less energetic than the visible light where our eyes are not accustomed for it though it tends to behave in the same manner.

Intended to Pick Faint Radio Signals of Distant Stars

A star releasing radio waves is not much different from the sun releasing visible light. Actually to someone far away or far in the future, the sun possibly is emanating primarily radio waves.ARCADE, when sent out in space was intended to pick up the faint radio signals of distant stars. Instead it received strong blare of radio and the input has been described as `boom’ by those who have been researching on it.

After some research done, the idea had been ruled out that it had been just very loud early stars. They also ruled out that it was coming from the dust of our own galaxy and was just a blast of radio, - `space roar’ which seemed to be part of the background noise with no explained reason. Though space roar has vexed the interest of several, there is yet no explanation for the same.
