Sonic Transit of Venus
Robert Alexander is an astronomical “sonification specialist”. He uses his musical training to take non-audible data and convert them into soundscapes to provide NASA scientists with a novel way to study the emissions from our Sun.
NASA satellites are constantly collecting data along the extreme range of emissions from the Sun. Alexander first compresses days of data into just seconds and then assigns different emissions (such as the various excited states of carbon) to different tones.
Above, he used signals collected during the 2012 Transit of Venus to help create a larger musical composition (listen to the full 17-minute version here). Listen to more of his solarsonic creations at NPR.
