Audio clips reveal noises made by alien moons, comets and rocket launches
comments
What does it sound like to land on the surface of Saturn's moon Titan or fly past the Martian moon Phobos?
Thanks to the European Space Agency you can listen to these sounds - and more - recreated by processing data from various spacecraft.
The amazing collection of clips include some that have been artificially amplified to be audible to humans, and others that are simply as they originally sounded.
The recent launch of a Soyuz rocket that took two European satellites into orbit can also be heard in one amazing clip. It took off from French Guiana at 9.46pm GMT on Friday 27 March (pictured), carrying two satellites that will expand Europe's Galileo system
The various noises from space are shared on Esa's esaops Soundcloud page.
One clip uses audio data collected by the Huygens probe as it descended onto the surface of Saturn's moon Titan on 14 January 2005.
The spacecraft carried with it acoustic sensors on the Huygens Atmospheric Structure Instrument (Hasi), which recorded the surroundings as the probe descended.
According to Esa they 'give a realistic reproduction of what a traveller on board Huygens would have heard during one minute of the descent through Titan's atmosphere.'

Elsewhere, the famous sounds of comet 67P Churyumov-Gerasimenko, as heard by the Rosetta spacecraft and Philae probe, are also replayed.
Rosetta's Plasma Consortium (RPC) recorded oscillations in the comet's magnetic field at 40 to 50 millihertz.
The 'music' was far below the frequency heard by humans - which typically ranges from 20 hertz to 20 kilohertz - but increasing the frequencies makes the noise audible.

The landing of Philae on the surface of 67P on 12 November 2014 is also heard in a brief clip, which is the actual recording of mechanical vibrations as it made its touchdown.
Philae subsequently bounced twice on the surface before coming to rest in an unknown location, wedged under a cliff somewhere in partial darkness.
Scientists at Esa are hoping that the probe will wake up in the coming weeks as sunlight recharges its batteries, letting them perform more key science on the surface.
Philae's first landing on the surface, seen here as pictured from the Rosetta spacecraft, can be heard in a short clip. The probe then bounced twice before coming to rest in an unknown location
The recent launch of a Soyuz rocket that took two European satellites into orbit can also be heard in one amazing clip.
It took off from French Guiana at 9.46pm GMT on Friday 27 March, carrying two satellites that will expand Europe's Galileo system - a civilian-run analogue to the US-run Global Positioning System (GPS).
Other launches include the radar imaging satellite Sentinel-1A, which is tracking Earth's environmental changes, and 1999's XMM-Newton X-ray observatory.
Put the internet to work for you.
