Time To Eat! :) Space Music - One of NASA’s observatories has discovered a giant black hole that hums. Located in the Perseus cluster of galaxies about 250 million light years from Earth, the black hole vibrates at the frequency of a B flat. But it is too low a pitch to be picked up by the human ear. Scientific instruments have placed the note at 57 octaves below middle C on a piano. ow.ly/2ycvDD
