Listen to sounds from outer space

Listen to an MP3 audio stream of Radio Astronomy, an art and science project which broadcasts sounds intercepted from space. Some of these sounds are rather spooky! From Radio Astronomy:

Radio Astronomy correlates the processes associated with broadcast radio - the transmission of audible information, and the processes of radio astronomy - the observation and analysis of radiated signals from planets, stars and other astrophysical objects. The work synthesizes these two areas. The signals from planets and stars are converted into audio and then broadcast on-line and on-air. The project is a literal interpretation of the term, "radio astronomy". It is a radio station broadcasting audio from space...

Many of the sounds emitted by these objects are fascinating from both an aesthetic and conceptual perspective, prompting comparisons with avant-garde music and electronic sound art. Yet very few people have heard these sounds, considering space to be silent, rather than the rich acoustic environment it turns out to be.
