The Sound of a Fermi Gamma-ray Burst
The NASA blog has posted a video, turning the above data-capture graph of ‘a gamma-ray burst, the most energetic explosions in the universe’ (above) into a piece of music:
What does the universe look like at high energies? Thanks to the Fermi Large Area Telescope (LAT), we can extend our sense of sight to “see” the universe in gamma rays. But humans not only have a sense of sight, we also have a sense of sound. If we could listen to the high-energy universe, what would we hear? What does the universe sound like?
… In translating the gamma-ray measurements into musical notes we assigned the photons to be “played” by different instruments (harp, cello, or piano) based on the probabilities that they came from the burst. This particular conversion is a fairly simple one; We built this on work done by other members of the LAT team (Luca Baldini and Alex Drlica-Wagner) who explored converting our data into music in different ways.
In the beginning of the song, before the burst starts, the harp plucks out a few lonely notes. After about half a minute, the piano joins in on top of the harp background, and the notes begin to pile on more and more rapidly. The cello enters the scene as the burst begins in earnest.

Very impressive piece of motion graphics exploring the operation and implications of mobile data. Of particular interest (to those in the US especially) is how long metadata is stored by mobile service providers.
Information technology has become a ubiquitous presence. By visualizing the processes that underlie our interactions with this technology we can trace what happens to the information we feed into the network.
