Siderius Nuncius

for Synthesizers, Electronic Sounds, and Signals from Space by John Holland (2005)   (4:18)

At the turn of the sixteenth century, Galileo observed never before seen details of the face of the Moon, the Milky Way, and nebulous stars with a powerful new telescope. These dramatic discoveries helped to establish the eventual acceptance of the heliocentricity of the Solar System.

Galileo also observed for the first time four Moons orbiting the planet Jupiter. In March 1610, he published his findings under the title Sidereus Nuncius, which ultimately caused an international stir. The new twenty-powered ‘spyglass’ or telescope used to make the observations was the first scientific instrument to amplify the human senses. Galileo was credited with being the first person to point the spyglass upward ‘toward the heavens’.

Signals from space include the sounds of Saturn recorded by NASA, Huygens Satellite radio and carrier signals, radar.
