James Webb Telescope recently discovered six new galaxies. These six galaxies are not the typical galaxies we often find. These galaxies, at the moment, are of great interest to scientists. The surprising thing about these galaxies is that they started forming just a few hundred million years after the Big Bang. To be specific, these galaxies started to form 350 million years after the Big Bang. When scientists observed these galaxies, they said they started to form just 500–700 million years after the big bang.
The real mystery of these galaxies is that they are in a very early stage of formation. In the early stages of galaxy formation, they do not have many stars. These six galaxies are exceptions because they contain the same number of stars as the Milky Way. This means that these galaxies are massive, and they are in the early stages of galaxy formation. These galaxies can be similar to the Andromeda galaxy. This is completely new for scientists, and it challenges the current idea of our understanding of how galaxies are formed.
When scientists initially observed this area of the sky, they believed they had made a mistake in classifying the object as a galaxy. The light they received was far too intense. They initially thought the light was coming from a single star or a quasar. There are a number of parameters that can affect the intensity of light, such as gravitational lensing, etc. But once scientists analyzed the data, they were astonished to see the massive size of these galaxies.
One of the scientists said, “The six galaxies we found are more than 12 billion years old, only 500 to 700 million years after the Big Bang, reaching sizes up to 100 billion times the mass of our sun.” This is too big to even exist within current models. This discovery could transform our understanding of how the earliest galaxies in our universe formed.
Conclusion
With this new discovery, scientists will probably need to reevaluate the cosmological model of how galaxies are formed. James Webb has given us so much new stuff in very little time that scientists can work with. We will undoubtedly discover many more new objects in the future. Some of them will definitely challenge our previous knowledge of the universe, which is necessary for our human race to be a multi-planetary species and study the origin of life.
