In space, no one can hear Earth scream. That is, unless you happen to have an extra Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) receiver. NASA has two, and they’ve recorded the Earth’s “chorus,” the sound of oscillating radio waves projected by the plasma radiation in the Van Allen Radiation Belt.
Take a listen here.
EMFISIS is actually one of two receivers strapped to Radiation Belt Storm Probes (RBSP), sent into orbit to collect data on the physical dynamics of these radiation belts with hopes of finding patterns providing scientists the capability of making future predictions about said belts.
The sounds recorded, dubbed “Earth’s Song,” bear no resemblance to Michael Jackson. The noises are in 16-bit mono, similar to CD-quality audio out of one speaker, are less like a song, and more like a bunch of crickets with a ’50s science fiction sound effects program. Not that it wouldn’t be easy to sample it into a hip hop track, but that aspiring artist might want to wait until the higher resolution stereo recording is released when the RBSP mission is complete.
