Researchers at the University of Cologne and the University of Masaryk in Brno (Czech Republic) have discovered the fastest known star, orbiting the black hole at a recorded time. The star, S4716, orbits the Sagittarius A *, a black hole in the center of our Milky Way, for four years and reaches a speed of 8,000 miles per second. The S4716 reaches close to 100 AU (a star unit) in a black hole — a small distance by astronomical standards. One AU covers 149,597,870 miles.The Astrophysical Journal published the study. Near the dark hole in the center of our galaxy lies a cluster of dense galaxies. This cluster, called the S cluster, is home to more than a hundred stars that vary in brightness and size. The S stars are moving very fast. S2 was described as acting like a huge man in front of you in a theater, blocking your view of what's important. Florian Peissker, lead author of a new study. The S2 thus frequently blocks the view of the galactic center. However, in short we can see the surrounding area of ​​the central black hole." By continuing to refine analytical methods, as well as visions covering nearly two decades, the scientist has now unequivocally identified a star around a large black hole in the middle in just four years. A total of five telescopes saw the star, four of the five being combined into one large telescope to allow for a more precise and detailed observation. It was completely unexpected for the star to be travelling so quickly, approaching so close to a large black hole, and following a stable course. indicated the limit that may be reached. seen with traditional telescopes,” says Peissker. In addition, this discovery sheds new light on the origin and emergence of a fast-moving star in the heart of the Milky Way. "In the short term, the compact orbit of the S4716 is strange," said Michael Zajaček, a astronomer at Masaryk University in Brno who participated in the study. Near the black hole, stars could not easily develop. Observation of S4716 — A Star with a 4-Year Orbit Around Sgr A *, by Florian Peißker et al., Astrophysical Journal (2022)..
