Space roar
Encyclopedia
The space roar is a natural phenomenon
picked up as a radio signal from outer space
. A NASA
team led by Alan Kogut discovered the roar. Described as a loud hiss, the team discovered the signal while trying to find traces of heat from first generation stars using an Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission
(ARCADE). This instrument is designed to detect radiation at centimeter wavelengths. Though signals from radio galaxies have been detected before, the space roar sounds six times louder than predicted. NASA scientists have yet to explain the space roar's source, but have currently ruled out primordial stars and all other known radio sources, as the space roar itself is six times louder than all other radio emissions currently discovered in the universe. The roar currently limits the study of the universe's earliest stars.
Natural phenomenon
A natural phenomenon is a non-artificial event in the physical sense, and therefore not produced by humans, although it may affect humans . Common examples of natural phenomena include volcanic eruptions, weather, decay, gravity and erosion...

Outer space
Outer space is the void that exists between celestial bodies, including the Earth. It is not completely empty, but consists of a hard vacuum containing a low density of particles: predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, and neutrinos....

Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission
Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission is a program which utilizes balloon satellite instrument package intended to measure the heating of the universe by the first stars and galaxies after the big bang and search for the signal of relic decay or annilhilation...
