The James Webb Space Telescope discovered an unusual galaxy. It is so special because its gas shines brighter than stars. This phenomenon is expected to be valuable in studying the history of the early cosmos.
Using the James Webb Space Telescope, astronomers have discovered a galaxy in the young universe whose gas emits more light than its stars. This unusual phenomenon, as scientists emphasize, provides valuable information about the early stages of space development. This is the first such recorded case in history.
The James Webb Space Telescope made another unusual discovery. Thanks to him, a team from the University of Oxford saw a unique galaxy that existed about a billion years after the Big Bang. What is special about this object is that the interstellar gas in the galaxy shines brighter than its stars.

The key to history
This discovery could be crucial for understanding the evolution of the universe. It is the missing link between the first stars and well-formed galaxies.
Research has shown that observations of galaxy 9422 almost exactly match computer models of gas heated by hot giant stars. According to Dr. Harley Katz, the stars are much hotter and more massive than the ones we see in the local universe. This is due to the differences between the early and modern universe.
In the local universe, hot, massive stars typically reach temperatures from 40,000 to 50,000. degrees C. However, according to the team, the stars in the galaxy found have a temperature of more than 80,000 degrees C. According to researchers, the galaxy is in a short phase in which there is a large number of massive, hot stars formed in a dense cloud of gas. This cloud is extremely bright because it is bombarded with lots of photons of light emitted by these stars.
It was expected that there would be such gas in the environment of the first generation of stars – called population III stars. However, scientists emphasize that there are no population III stars in this galaxy. Data from the Webb telescope reveal an excess of chemical complexity.
– The alien stars of the galaxy are different from the ones we know – they may give an idea of the way from primitive stars to understand the types of galaxies we know today, says Dr. Katz.
Despite the important discovery, many questions remain unanswered. Are the observed conditions common in galaxies from that time, or is it a rare occurrence? Could they provide additional information about earlier stages of galaxy evolution? – astronomers ask.
– This is a very exciting time when we can use the Webb Telescope to study a previously inaccessible period in the history of the world – emphasizes Dr. Cameron. – We are just beginning to make new discoveries and gain a wider understanding – he said.
