Marsquakes, the Milky Way and swirling gases on Jupiter are represented through sounds in a new NASA compilation, Sinister Sounds of the Solar System, released just in time for Halloween.  The space agency and astronomy researchers have translated data from radio signals and other phenomena into audio tracks for many years, but the recent Halloween-themed release compiles such tracks like never before.  Take a listen by clicking HERE -- if you're not TOO scared of what's out there.
