Did you know that the ionosphere makes noise? Or that that noise is actually possible to record? This recording shows that the ionosphere, part of the upper atmosphere that is ionized by solar radiation, can indeed be recorded. Here you have the opportunity to listen to the electrical static in stereo synchronized from recordings made at the Naval Research Laboratory in Washington DC and at Dartmouth College in Hanover, New Hampshire. Incidentally, this is a Cook classic, especially favored by DJs and spin artists.
