Do Black Holes Make Sound?

For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.

Do black holes produce noise?

In space you can't hear a black hole scream, but apparently you can hear it sing. In 2003 astrophysicists working with NASA's orbiting Chandra X-ray Observatory detected a pattern of ripples in the X-ray glow of a giant cluster of galaxies in the constellation Perseus.

Is a black hole quiet?

Researchers from the European Southern Observatory say this black hole is unique, because it does not react violently with its environment: it is silent, practically invisible and the closest black hole to Earth. They detail their findings in a study published Wednesday in the journal Astronomy & Astrophysics.
