One of the amazing properties of black holes is that they cannot emit light or radio waves. However, surrounding materials can emit electromagnetic waves that can be recorded. That’s how NASA managed to capture such a beam in V404, a swan galaxy with a black hole.
The researchers then converted the electromagnetic radiation into sound, allowing them to “hear” the voice of the black hole.
It is located 7,800 light-years from Earth
The system is about 7,800 light-years from Earth, and the black hole pulls in matter and energy from nearby stars. The first data is transmitted as high frequency sound and the second data is transmitted as low frequency sound. Watch the video below.
The V404 Swan system itself is a binary system. It is a black hole with about 12 solar masses and the mass of a star of spectral class G or K. Due to their proximity to each other, black holes drag their mass onto the star, causing a radiative explosion. The V404 Swan system is considered a variable star that changes in brightness over time.
In 1938, 1956 and 1989 it produced powerful bursts of energy and is also a source of X-ray bursts. This is not the first video like this. NASA has previously released images of terrifying black holes. It is located 200 million light years from Earth. The V404 Swan black hole sounds different.
