sounds captured for first time
A black hole is a space in which the gravitational pull is strong and everything is trapped. Even light cannot escape. These black holes are usually formed from the dying stars.
released the eerie sounds emanating from black holes 250 lightyears away, this is what scientists say is, in relative terms, extremely close to Earth.
“They are being heard 144 quadrillion to 288 quadrillion times louder than their original frequency,” NASA said.
stated that it increased the pitch of the sound by 57 and 58 octaves to make them audible for the human ear.
The NASA account tweeted: "The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound."
