Webb Telescope Detects Winds That Are Killing Galaxies

Massive Gas Outflows Could Doom Galaxies to Extinction

According to Radiotrek — Світ: Using the James Webb Space Telescope, astronomers have identified powerful galactic winds that strip galaxies of the gas needed to form new stars. This discovery helps explain why massive galaxies in the early universe ceased to exist. The study focused on a galaxy that existed roughly one billion years after the Big Bang, where a colossal stream of cold gas was observed blasting out into space.

This gas serves as the primary raw material for star formation. Scientists warn that if the outflow continues, the galaxy could stop producing new stars entirely in less than 50 million years. Previously, researchers believed supermassive black holes were the only cause of such processes, but the new data points to additional factors at play.

Examining the CRISTAL-02 System

The research centered on a system known as CRISTAL-02, which consists of several galaxies merging with one another. In CRISTAL-02, star formation is occurring twice as intensely as in similar galaxies. The massive young stars forming there end their lives in powerful supernova explosions. These explosions generate strong galactic winds that blow gas out of the galaxy.

"This gas is the main building material for new stars. When it leaves the galaxy, star formation gradually stops, and the galaxy itself begins to fade." - One of the study's authors

The publication was authored by Olena Shvydka. This research opens new avenues for understanding galaxy evolution in the early universe and could have a significant impact on astronomical science.

These findings highlight the importance of studying the interplay between stars, gas, and black holes in galactic evolution. They may reshape our understanding of how galaxies form and develop, as well as the factors that lead to their demise. Further studies in this area could help astronomers better grasp the dynamics of the universe and the evolutionary processes taking place within it.

Understanding the dynamics of galaxy formation is crucial, especially when considering recent findings about star creation processes. For instance, the emergence of mini universes within stars sheds light on the intricate relationships between stellar evolution and cosmic structures. This connection could provide further insights into how galactic winds, like those observed in the CRISTAL-02 system, influence the lifecycle of galaxies.
