One of the more recent approaches of studying astronomy and development of planets, stars & galaxies is "stellar seismology": collecting radiowaves from far distant space objects and compressing them into audible soundwaves. Here is the fourier spectrum of a "recording" taken over 60 days, from HD49933, as shown by the Institute d'astrophysique spatiale:
More revealing than looking at this graph is to listen to the sound of space on Jodcast - be patient, they talk a bit for about the first 5 minutes - which is really interesting, but some of you might just want to hear planets sing.. they'll sing, no worries..
A short article about the most recent study can be found here on BBC, also containing a few more sample sound files.
Isn't that eerily like whale singing?
We got one more, from an earlier study, also reported about on BBC: listen to micro-flares of the sun!
