The results indicate that humans may be lacking fundamental knowledge about the universe, potentially requiring the need for new information on galaxy formation or modifications to cosmology. By conducting a "stress test" on the galaxies, scientists aimed to gain a better understanding of their formation.

This unexpected discovery is a significant departure from what scientists had previously expected and may require a new approach to understanding the universe. The results suggest that something might be wrong with the current cosmological paradigm known as ΛCDM which has long guided scientific thinking about the universe.This is because normal galaxies convert only around 10% of their gas into stars, whereas these newly discovered galaxies are thought to be converting almost all of it, indicating a theoretical possibility. The paper, titled " Stress testing ΛCDM with high-redshift galaxy candidates" published in the journal Nature Astronomy, raises a significant issue for scientists. Similarly, the other five galaxies examined by the researchers contained more stars than would be expected for a cluster of their age. This meant that the researchers were observing an image of the galaxy as it looked 700 million years after the Big Bang, which is only 5% of the current age of the universe.ĭespite its age, the galaxy contained 100 billion stars, which is the same number of stars found in the current-day Milky Way galaxy that has existed for an additional 13 billion years. However, the light that the JWST had detected from the star took 13 billion years to travel to Earth. They estimated that the age of the first star they analyzed was 13.8 billion years old. In February, researchers from Swinburne University in Australia used data gathered by the JWST to examine six galaxies. It unveiled its first official images in July 2021. The JWST's goal is to detect light from the earliest celestial bodies in the universe. Six Galaxies That Are Too Big For Their Age
