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.
In space, no one can hear you scream -- but you may hear a knock. When he was alone in a spacecraft in 2003, astronaut Yang Liwei reportedly heard a "knock" despite being alone.
Now NASA is stepping in to provide some insight into what could actually be causing this scary pattern. NASA scientists believe the ominous noises could potentially be the "background noise" of ...
RELATED: Best space photos of 2015. By measuring the sounds, scientists are able to determine the mass and age of each individual star.
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
Quindar tones were named for the manufacturer Quindar Electronics, Inc., now QEI. Glen Swanson, historian at NASA's Johnson Space Center who edited the Mission Transcript Collection, and Steve Schindler, an engineer with voice systems engineering at NASA's Kennedy Space Center, confirmed the origin of the name. "Quindar tones, named after the ...
A few months ahead of the craft's imminent suicide via controlled crash into Saturn, Cassini gave us a rare glimpse into the sounds of the planet it orbits. NASA records bone-chilling sound in gap ...
Sound localization technology is used in some audio and acoustics fields, such as hearing aids, surveillance [1] and navigation.Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival approach, limiting sound localization to two-dimensional space, and are not practical in noisy conditions.
