Extreme magnetic fields near our galaxy’s black hole are preventing stars from being born, JWST discovers

Stars are architectural engineers for almost all chemical elements in the universe, including those decisive in life as we know them, such as carbon and oxygen. However, despite contracts of research, the aspects of the formation of stars are vague like thick clouds and gaseous darkness in which children’s stars are included. The James Web telescope notes on the Saga C (SGR C), a region that forms stars in the heart of the Milky Way and it appears to be fewer stars than expected, highlighting some of these mysterious operations.

Despite the residence of one of the most stars environments in Galaxy-only 200 light years away from the super black hole Sagittarius a* – It contains wide reserves of molecular gas, SGR C does not generate many stars as astronomers estimate this. In 2023, and James Web telescope for space (JWST) Equipped astronomers with the first infrared data for this stellar custody, allowing them through the mysterious blanket of gas and dust and the study of its young stellar residents in more detail.

A new analysis of these observations has now been revealed about dozens of bright hot plasma threads that resemble a needle, some of which are several light years, coordination inside and outside the SGR C

“We certainly did not expect these threads,” said Robin Fedriani, a post -PhD researcher at the Gutto Institute at A. statement. “It was a completely steadfast discovery.”

Federiani and his colleagues are suspected that these newly discovered threads are carved by nearby magnetic fields, which are extended and amplified by turbulent movements of gas around the black hole in the middle of our galaxy, bow*. this Black hole It has a mass of about four million times from our sun and the exercise of the tidal forces on its surroundings.

These magnetic forces may be strong enough to counter the collapse of the typical gravitational stars of molecular clouds, and instead, the materials are limited to dense strands seen in JWST photos, which helps to clarify the reason for the formation of SGR C less than the expected stars, according to the new paper.

“For the first time, we see directly that the strong magnetic fields may play an important role in suppressing the formation of stars, even in small standards,” the world of astronomical physics from the University of Colorado Bolder, which led one Among the two new papers, JWST notes, he said in another statement.

“This is an exciting field of research in the future, where the influence of strong magnetic fields, in the midst of our galaxy or other galaxies, has not been seen on the entire star environment,” has not been considered Samuel Crowe from the University of Virginia, second A new paper, added in the same statement.

Bali and his team used JWST data to conclude that two huge young stars near the SGR C Nursery Center are located between parallel parallels, which are likely to track the walls of the cavities created by strong stellar winds.

Due to the extremist environment in which it lies, the notes showed that SGR C has expelled many of its stars, indicating that the nursery can fade in a few hundred thousand years-and flashing the eye in the context of the history of the universe of 13.7 billion years.

“It is almost the end of the story,” Bali said in the statement.
