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.
