Gas surrounding these galaxies is suspected to be almost purely hydrogen and helium, the earliest elements in the cosmos.
JWST's sensitive instruments detected this gas, providing insights into early universe star formation processes.
Scientists discovered three galaxies using JWST that are potentially forming when the universe was 400-600 million years old.
Scientists have made a groundbreaking discovery using the James Webb Space Telescope (JWST), as they have identified three galaxies that are potentially forming when the universe was only 400 to 600 million years old. These galaxies, which are surrounded by gas that researchers suspect to be almost purely hydrogen and helium, the earliest elements in the cosmos, were detected due to an unusual amount of dense gas surrounding them. This gas will likely end up fueling the formation of new stars in these galaxies.
The JWST's sensitive instruments were able to detect this gas, providing scientists with valuable insights into the early universe and its star formation processes. According to researchers from NASA, ESA, and CSA, these galaxies are like
Astronomers using the James Webb Space Telescope have found three of our universe’s earliest galaxies, spotted actively forming when the cosmos was just 400 million to 600 million years old.
These galaxies are like sparkling islands in a sea of otherwise neutral, opaque gas.
The JWST’s powerful infrared eye captured how light from the three observed galaxies was absorbed by large, dense reservoirs of neutral hydrogen gas around them.

The article contains some inflammatory rhetoric and appeals to authority but no formal fallacies or direct falsehoods. The author describes the images from the James Webb Space Telescope as showing 'the first “direct” images of galaxy formation' which is an appeal to authority based on the reputation of NASA and other institutions involved in this project. Similarly, when stating that 'you could say that these are the first “direct” images of galaxy formation that we’ve ever seen,”' it is an inflammatory rhetorical statement meant to emphasize the importance and novelty of these findings. However, no formal fallacies or falsehoods are present in the article.

You could say that these are the first 'direct' images of galaxy formation that we've ever seen,
University of Copenhagen researchers have used the James Webb Space Telescope to observe the formation of three galaxies that are more than 13 billion years old, making it the first time in history that formative galaxies have been seen.
These are the first direct images of galaxy formation that scientists have ever seen.
Through the James Webb Space Telescope, researchers were able to see signals from large amounts of gas that accumulate and accrete onto a mini-galaxy in the process of being built.
The discovery contributes important knowledge about the universe and has been published in the prestigious journal Science.
These galaxies were formed about 400-600 million years after the Big Bang, during 3-4% of the universe’s overall lifetime.
