NASA recently tweeted an eerie audio clip that represents actual sound waves rippling through the gas and plasma in the Perseus cluster, which is 250 million light years from Earth.” — posted yesterday (8.22) by Vice‘s Vicky Ferreira.
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. Here it's amplified, and mixed with other data, to hear a black hole! pic.twitter.com/RobcZs7F9e
