If there were a variety show in the vast and boundless universe, the black hole at the centre of the M87 galaxy would undoubtedly be the brightest star, attracting the attention of countless interstellar viewers. It is like a deep stage, and the black hole is the most eye-catching focus on the stage. Recently, this black hole has been really hot. An international team of researchers, like photographers of the stars, have teamed up to capture the black hole's remarkable moments. The jet of the black hole is no longer static and cold, but like a dancer, gracefully twisting and turning in the universe, performing a mysterious “swing dance”. The swing of the jet stream is so periodic, just like the dancer with the rhythm of the music, lightly rotating, jumping. Each swing, as if telling the secrets of the deep universe, so that people are full of endless curiosity and reverie to the mysterious universe world.
2019, this black hole also had the first “face”, the first black hole in the history of mankind's protagonist of the photo. Black holes are not only a gravitational big brother, but also very good at “spitting fire”. This is because when a black hole engulfs matter, it produces high-speed jets of plasma, which are like huge columns of light emanating from the poles of the black hole. Recently, an international team of researchers discovered that these jets are not static, but swing regularly, as if they were swing dancing in the universe. The observation was an international bonanza, involving several observatories and research organizations from around the world. They used a variety of telescopes, from radio telescopes to optical telescopes, to capture the “dance” of the black hole jets through different wavelengths. It's like a giant global live show, with all the equipment, pointed at the M87 galaxy, watching the black hole's every move.
So what's so special about this swing dance? The periodic wobble of the black hole jet provides valuable data that can help scientists gain a deeper understanding of the properties and behaviour of black holes. For example, the wobble could be due to variations in the magnetic field around the black hole, or because the black hole itself creates instabilities during its rotation. These findings not only shed light on the internal mechanisms of black holes but may also provide new clues to the evolution of the universe as a whole. After all, black holes can be quite influential in the universe, and their activities may affect the formation and evolution of galaxies. The results of this observation are like a documentary on swing dancing in the universe, revealing the rhythms and rhythms of black hole jets. With this data, scientists can better model and understand the behaviour of black holes and even predict the occurrence of similar phenomena in other galaxies.
This observation is just the beginning. With the advancement of science and technology and the investment of more advanced equipment, scientists will continue to explore the secrets of black holes. Perhaps in the future, we will find more similar “cosmic dance”, further unravelling the mystery of black holes and the universe.
The black hole at the centre of the M87 galaxy, its delicate “swing dance” not only makes astronomers as excited as a child dancing but also makes us, the ordinary people who are full of curiosity about the universe, the vastness of the sea of stars more than an unspeakable awe. Imagine the black hole, the “dancer” in the universe, in the endless time and space, with its jet stream swinging to weave a song and a song of the universe's hymn. He may be in a distant galaxy, silently performing their unique dance, waiting for us to discover, to appreciate them. Just like explorers searching for unknown treasures, we will continue to delve into the uncharted territory of the universe, exploring those mysteries that have yet to be revealed. Let's wait and see, on the stage of the universe, every performance will be unique, let us look forward to that exciting moment together.
