Scientists want to launch telescope to study black holes from space
Black holes are among the most extreme yet fascinating objects in the universe.
Listen to the creepy sound of a black hole 250 million light years from Earth, announced by NASA
Sound waves cannot travel through a vacuum, so there can be no sound in space. However, science can help us "hear" the universe in many ways.
Recently, the NASA Exoplanets account, which specializes in posting scientific information about the universe outside the Solar System of the US National Aeronautics and Space Administration (NASA), posted an article explaining how NASA scientists "hear" the sound of a black hole .
Twenty years ago, NASA's Chandra X-ray Observatory captured the sound waves of a black hole at the center of the Perseus galaxy cluster, 250 million light-years away, in astronomical data. They were pressure waves (sound waves) that stretched 30,000 light-years across the 11-million-light-year-wide Perseus galaxy cluster, which is also the medium through which the sound waves traveled.
The sound waves emitted from this monster black hole are 57-58 octaves away from middle C (C4), well below the limit of human hearing.
Recently, NASA scientist Kimberly Arcand converted this astronomical data into a sound that humans can hear by raising the tone to 57-58 octaves, increasing the frequency 4 billion times compared to the original. This process is called "sonification" of data from black holes.
Below is a "sound" video of the pressure wave data in X-rays emitted from the giant black hole in the Perseus galaxy cluster after being upscaled.
In addition, by “sonifying” the data obtained, Arcand also recorded the sounds of many other objects in the universe such as interstellar clouds or stars… They all have different sounds.
The mysterious history of black holes has been decoded by scientists
One of the common misconceptions about black holes is that they not only swallow matter, but also the history of that matter. The truth about the history of black holes in the universe has finally been revealed.
This is what you would see if you fell into a black hole
No one knows what would happen if you fell into a supermassive black hole like the one at the center of the Milky Way. To answer this question, NASA researchers created a simulation using the Discover supercomputer at the NASA Climate Simulation Center that describes what would happen if you fell into a supermassive black hole like the one at the center of the Milky Way.
