The recent observation of young stars near the Milky Way’s central black hole raises intriguing questions. This discovery contradicts predictions about star formation in hostile environments.
Clusters of new stars have been discovered near the central black hole of the Milky Way (also called “our galaxy”, or sometimes…), in a chaotic region where they should not exist.

In the vicinity of the supermassive black hole (In astrophysics, a supermassive black hole is a black hole whose mass is approximately one million…) of our galaxy (A galaxy is, in cosmology, an assembly of stars, gas, dust and…), gravitational and radiative forces create a very unfavorable environment for the birth of stars. However, for decades, astronomers have observed young stars near this galactic center. One particular cluster, known as IRS13, was discovered more than 20 years ago. These stars are around 100,000 years old, which is very young compared to the Sun (4.6 billion years) or even to the Milky Way (13.6 billion years).
Florian Peißker, astronomer at the Institute of Astrophysics (from the Greek astro = star and physiqui = physics) is a branch. ..) from the University of Cologne, said that analyzing this cluster could be the key to understanding the presence of these young stars in such a hostile region. According to the new research, these stars may have migrated from the galactic periphery and ultimately been trapped by force. , and also, metaphorically, a…) gravitational force of the central black hole. During their passage, they created an arcing shock, stimulating the formation of other stars.
The James Webb Space Telescope also identified signs of water ice in the galactic center near IRS13, further evidence of new star formation. These discoveries continue to puzzle astronomers, but also open new avenues for understanding the complexity of our Universe (The Universe is the set of all that that exists and the laws that govern it.).
