Audio data collected by the Huygens Atmospheric Structure Instrument (HASI), which includes an acoustic sensor, during Huygens' descent, 14 January 2005. This recording is a laboratory reconstruction of the sounds heard by Huygens' microphones. Several sound samples, taken at different times during the descent, are here combined together and give a realistic reproduction of what a traveller on board Huygens would have heard during one minute of the descent through Titan's atmosphere.

Chorus Radio Waves within Earth's Atmosphere

Saturn’s ocean-bearing moon also bears some spooky sounds! Here’s one captured by our Cassini spacecraft.

Cassini: Enceladus Sound

Saturn is a source of intense radio emissions, which were monitored by our Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn.

Cassini: Saturn Radio Emissions #1

During its close flyby of Earth in 2013, NASA's Jupiter-bound Juno spacecraft listened for -- and heard -- a coordinated, global transmission from amateur radio operators using its radio and plasma wave science instrument. The message said "HI" in Morse code. More details about this sound can be found here: http://photojournal.jpl.nasa.gov/catalog/PIA17744

Juno: Morse code "HI" received from Earth

Kepler: Star KIC12268220C Light Curve Waves to Sound

Kepler: Star KIC7671081B Light Curve Waves to Sound

Stardust: Passing Comet Tempel 1

Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013. This sound reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1.

UPDATE (20 Aug 2015): What made the comet sing? Scientists working on Rosetta's RPC instrument have found out why 67P/C-G was singing. Via http://wp.me/p46DHN-1nN

ORIGINAL Citation (Oct 2014): Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased in this recording. This sonification of the RPC-Mag data was compiled by German composer Manuel Senfft (www.tagirijus.de).  Read full details in ESA's Rosetta blog: http://wp.me/p46DHN-Li

A Singing Comet

Sensors in the feet of Rosetta’s lander Philae have recorded the sound of touchdown as it first came into contact with Comet 67P/Churyumov-Gerasimenko. The instrument, SESAME-CASSE, was turned on during the descent and clearly registered the first touchdown as Philae came into contact with the comet, in the form of vibrations detected in the soles of the lander’s feet. 

Technical note: This is the actual sound file; i.e. it is a recording of mechanical vibrations at acoustic frequencies. No modification was necessary except for some technical adjustments (e.g. the .wav format requires amplitude normalization). Actual frequency content and duration are unchanged.

Philae touchdown makes a thud

The Voyager 1 spacecraft has experienced three "tsunami waves" in interstellar space. Listen to how these waves cause surrounding ionized matter to ring. More details on this sound can be found here: http://www.nasa.gov/jpl/nasa-voyager-tsunami-wave-still-flies-through-interstellar-space/

Voyager 1: Three "Tsunami Waves" in Interstellar Space

This recording was produced by converting into audible sounds some of the radar echoes received by Huygens during the last few kilometres of its descent onto Titan. As the probe approaches the ground, both the pitch and intensity increase. Scientists used the intensity of the echoes to speculate about the nature of the surface.

Huygens Alien Descent Radar

Ever wonder how the International Space Station alarms sounds? This emergency alert is the last thing astronauts on the ISS ever want to hear as they work 400 km above Earth in the vacuum of space.   
 
This sound was sent to us by the Columbus Control Centre, near München, Germany, the operations centre for ESA astronauts and the Columbus laboratory, part of the orbiting weightless research centre.

The alarm is sounded on the International Space Station to alert astronauts to life-threatening emergencies such as loss of pressure or fire. The astronauts would immediately convene near their Soyuz spacecraft that serve as lifeboats, but these kind of emergencies are extremely rare and the alarm has sounded only a handful of times despite the Space Station having been inhabited since 2000. 

Most astronauts on a six-month space flight will only ever hear the sound during a practice session.

Regular 'fire-drills' are performed to make sure that even in a worst-case scenario everybody knows what to do. Mission controllers from the international partners that run the Space Station in Russia, USA, Europe and Japan re-enact scenarios with the astronauts in space. In critical situations the teams on ground need to communicate efficiently, act quickly and coordinate a solution between each other and the astronauts flying 400 km above them.

International Space Station siren

This minute-long sound file covers about 4 hours of real time - from when ESA's Huygens probe deployed its main parachute and started transmitting, down to its landing on Titan, Saturn’s largest moon, two and a half hours later and then around an hour on the surface. The sound is a tone whose frequency depends on the strength of Huygens' signal as received by the receiver on board Cassini. This in turn depends on the distance between Cassini and Titan, and on the angle Cassini is seen from the probe.

Cassini-Huygens is a joint NASA/ESA/ASI mission. NASA’s Cassini spacecraft continues to orbit Saturn, making an extensive survey of the ringed planet and its moons. The ESA Huygens probe is the first to land on a world in the outer Solar System - on the surface of Titan, Saturn’s largest moon. Data from Cassini and Huygens may offer clues about how life began on Earth.
