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.
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.
CMEs generate plasma shock waves in space, similar to the sonic boom caused by aircraft flying faster than the speed of sound in Earth's atmosphere. The solar wind 's equivalent of a sonic boom in the solar-system plasma medium can accelerate protons up to millions of miles per minute – as much as 40 percent of the speed of light. [ 10 ]
Until now, scientists have held that these “chorus waves” form at points in space along the Earth’s magnetic field – which resembles that of a large bar magnet – out to about 51,000 km ...
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 ...
NEW YORK (AP) — Scientists have detected cosmic waves that sound like birds chirping in an unexpected place. These bursts of plasma, called chorus waves, ripple at the same frequency as human hearing. When converted to audio signals, their sharp notes mimic high-pitched bird calls.
3GP is defined in the ETSI 3GPP technical specification. [1] 3GP is a required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia Broadcast/Multicast Service (MBMS) and Transparent end-to-end Packet-switched Streaming Service ().
