NASA has released a short audio clip of a black hole from a nearby galaxy. Here is how the Black Hole sounds to human ears.
Black Holes are the most interesting heavenly bodies to look at, even though we only managed to get our first actual glimpses of one. A Black Hole is theoretically known to have so much gravity that nothing escapes its clutches, not even light. And since space is majorly filled with vacuum, we cannot hear it too. However, NASA has now managed to figure out how a black hole sounds. We had gotten sounds of a black hole earlier in the year and now NASA has come up with remixed sounds of the same.
The Perseus Galaxy cluster has a Black Hole at its center that sits 200 light years away from Earth. Earlier this year, scientists had managed to record its sounds via the NASA Chandra X-Ray observatory and now, the same recording has been re-released with additional data obtained about the Black Hole. NASA has released the clip on its social media handle, where the data obtained from the observations has been fused into the sound recordings. The result is a highly scary groan that logically defines a Black Hole the best.
Black Hole sounds scary!
The short audio clip released by NASA is a remixed version of the original and it goes on to show, or rather make us hear how the pressure waves are rippling through the hot gas surrounding the event. The sound resembles vastly of groaning and rumbling, which is similar to the background scores in most horror movies.
For those who wonder how we are able to hear a Black Hole 200 light years away when the space is said to be all vacuum, there is a simple explanation. This Perseus Black Hole is surrounded by lots of gas material and NASA scientists have managed to pick up the data from the same media.
“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,” says NASA via its NASA Exoplanets handle.
Scientists have more to discover on Black Holes in the coming years. We have only got our first blurry glimpse at an actual black hole image, which seems largely similar to the artist renditions we have seen in images and sci-fi movies.
