Following the blow, scientists decided to apply the same sonification technique to the black hole at the center of the galaxy M87. We are talking about the same black hole, a photo of which we saw in 2019 thanks to the Event Horizon Telescope. Data from the Chandra Observatory, the Hubble Space Telescope and the ALMA radio telescope network in Chile were used to “voiced” this particular black hole. In the photos of these three instruments, the black hole is located in the lower left part of the frame. A narrow jet of matter emitted from the vicinity of the black hole extends towards the top and right edges. To distinguish signals from the above-mentioned instruments, scientists assigned the lowest tones to radio waves (ALMA), the middle tones to the optical range (Hubble), and the high tones to x-ray data (Chandra).
The topic of black holes will come back to us soon. A press conference was announced for May 12, 2021, at which we will get to know the latest observational data collected by the Event Horizon Telescope. Quite a lot can be expected from the conference, as the team of scientists behind the discovery argues that the presented data will be groundbreaking and will be supported by rich audiovisual material.

It is therefore possible that we will finally see the much-anticipated photo of a supermassive black hole at the center of the Milky Way. It would certainly be a remarkable achievement. While this object, also known as Sagittarius A *, is close to us, only 26,000 light-years from Earth, it is hidden behind a dense maze of stars and gas that make it difficult to photograph. Is it SgrA *, or something else, we will find out only on May 12.
