Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere. It is not actually sound, and it can be detected through a radio receiver , which is an electronic device that receives radio waves and converts the information given by them to an audible form.
Space weather phenomena can interfere with or damage these satellites or interfere with the radio signals with which they operate. Space weather phenomena can cause damaging surges in long-distance transmission lines and expose passengers and crew of aircraft travel to radiation, [3] [4] especially on polar routes.

Eerie noises have been recorded all over the world recently. NASA is now offering up a possible explanation.
This was the first time that radio waves were detected from outer space. [1] The first radio sky survey was conducted by Grote Reber and was completed in 1941. In the 1970s, some stars in the Milky Way were found to be radio emitters, one of the strongest being the unique binary MWC 349 .
The source can be roughly located at , between New Zealand and South America Scientists/researchers of NOAA speculate the sound to be underwater volcanic activity . The Upsweep's level of sound (volume) has been declining since 1991, but it can still be detected on NOAA's equatorial autonomous hydrophone arrays.
Noise storms can last from hours to weeks, and they are generally observed at relatively low frequencies between around 50 and 500 MHz. Noise storms are associated with active regions . [ 61 ] Active regions are regions in the solar atmosphere with high concentrations of magnetic fields, and they include a sunspot at their base in the ...
This leads to noise at the output of the detector, much like radio static. In addition, for sufficiently high laser power, the random momentum transferred to the test masses by the laser photons shakes the mirrors, masking signals of low frequencies. Thermal noise (e.g., Brownian motion) is another limit to sensitivity
