The oldest history of our universe seen through telescope
Astronomers are slowly getting a glimpse of what our universe was like 13 billion years ago, a discovery that could revolutionize our understanding of how the universe formed. In July 2022, scientists will observe the early history of our universe through the James Webb Space Telescope. From this picture, scientists can know what our space looked like billions of years ago.
Research related to this has been published in the journal Nature on Wednesday. The researchers estimate that they have observed smaller and smaller galaxies. But he has made an even greater discovery. They found six massive galaxies 13.1 billion years old, the same age as our Milky Way galaxy.
bigger galaxy than expected
The James Webb Space Telescope observed six massive galaxies 500 million to 700 million years after the Big Bang. The mystery is fundamentally changing accepted ideas about how galaxies formed, CNN reports. “These galaxies are much larger than expected,” said co-author Joel Leja, assistant professor of astronomy and astrophysics at Penn State University. We expected these galaxies to be smaller and lighter than 13 billion light-years away, but the galaxy was found to be almost as mature as it is today.
the first picture came in july
The James Webb is the most modern telescope ever built. It can also clearly see infrared light which is not visible to humans. It is able to capture the light coming from distant galaxies and fainter stars. It released its first photo in July 2022, after which Leja and his colleagues began the study. He was absolutely stunned after seeing the pictures. The distant galaxies were much larger than expected and looked like a point.
According to the Big Bang Theory, the universe began with a big bang 13.8 billion years ago. After this, Anant Galaxy was formed. The now discovered galaxy is also about 13.1 billion light-years away. That is, it has taken 13 billion years for the light to come from here. What we are seeing today happened 13 billion years ago and the situation would have been different today.
Yet the Galaxy fully matured 13 billion years ago. One of the biggest surprises for scientists is how these galaxies grew so rapidly in the early universe. According to the theory we have now, these galaxies should have been clouds of dust and gas. According to Leja, the discovery calls into question the theory of the earliest times of the Galaxy.
