that The V404 Cygni black hole he is 7800 light years away away from Earth. Although no light leaks from within it, radiation is pushed into space from its edge with great force. On their way, the rays bounce off clouds of gas and dust, as do searchlights in fog.

NASA calls these rays “light echoesAnd I made it sonication One understands the process of pinging data, as it is Chandra Project sound world He does regularly. Pay attention YouTube video It starts out loud:

The black hole with mass in between 5 and 10 suns It sucks in material from a star orbiting Cygni. Matter moves towards it on a disk.

X-rays and cosmic clouds

X-rays are regularly emitted by matter, among other things. They are spread by cosmic gases and dust clouds. Some of them are heading toward Earth and were captured by NASA’s Chandra X-ray Telescope and the Neil Gerrell Rapid Observatory.

From this, astronomers calculated the distance between V404 Cygni and Earth and at what distances the radiation it would emit. With this data, researchers can also learn more about the formation and nature of cosmic clouds.

Noise and musical notes

Now this data has been processed and converted into sounds. The black hole is in the center of the image white wreath Compatible with X ray. Areas where light reverberates when passing through Clouds of gas and dust arise, are red (Swift) and blue (Chandra) shown. They make a ticking sound that increases the noise. Chandra data will be included higher tones Illustrated using Swift depths.

The image was also compiled using data from Digital Sky Survey impregnated. It shows the stars in the background, recognizable by visible light. you match Musical notes Pitches are based on how bright they are. Chandra and Swift’s individual audio files and photometric data can also be heard on Chandra’s website (over here).
