NASA just released the sound of a black hole, and it’s as cool as it is disturbing. NASA’s Exoplanets Twitter account released the audio from the Perseus galaxy cluster, 240 million light years from Earth. becomes audible for the first time. Scientists say the black hole sends out pressure waves that cause ripples in the hot gas, which can translate into a note. To be clear, however, the actual note is one that humans cannot hear. This is about 57 octaves below middle C. But the folks at NASA say they changed the note so we could hear it, amplified it, and then mixed it with other data they have about black holes.
