The voice of a nearby monster: NASA turned the light “echo” of a black hole into sound
One of the amazing features of black holes is that light and radio emission cannot escape from it. However, the surrounding material may emit electromagnetic radiation that can be detected. And now NASA was able to detect such radiation from the star system V404 Cygnus, where there is a black hole. After that, the researchers translated the electromagnetic radiation into sound, which made it possible to “hear” the voice of the black hole.
This system is about 7,800 light-years from Earth, and the black hole is sucking matter and energy from a nearby star. The beat data was obtained from the Chandra X-ray Observatory and the Neil Gerels Swift Observatory. The data of the first is represented by high-frequency sounds, the second – by lower ones. You can watch the video with sound below.
The V404 Cygnus system itself is dual. It contains a black hole with a mass of about 12 solar masses and a star of spectral type G or K. Due to the close proximity of the two to each other, the black hole pulls mass from the star.
V404 Cygnus is considered a variable star, meaning its brightness changes over time. In 1938, 1956 and 1989, it produced powerful bursts of energy, and the system also generates bursts of X-rays.
This is not the first video of its kind. Earlier, NASA published a recording of the eerie sound of a black hole. It is located at a distance of 200 million light years from Earth. The black hole from V404 Cygnus sounds different.
