After decades of collecting celestial sounds - from rocket launches and astronaut dialogue to alien lightning and interstellar plasma - NASA recently set up a SoundCloud account, letting it stream the audio clips for anyone to hear.
NASA offers 63 sounds so far. 'A Giant Leap' Neil Armstrong's most famous words when his foot touched the surface of the Moon was the first SoundCloud clip that NASA posted online, 'mother nature network' reported.
NASA made this recording in 2012 with its EMFISIS probe.
Another audio NASA uploaded is 'Saturn Radio'. Saturn is home to dramatic auroras that are a lot like the northern and southern lights that dance around the Earth's poles when solar wind hits the upper atmosphere.
These lights are closely related to the planet's strong radio emissions, first detected by the Cassini spacecraft in 2002.
'Lift Off' are the sounds of the first manned-mission to the Moon, Apollo 11. The clip includes lift off, as well as the applause in the space center.
