The James Webb Telescope discovers the four oldest galaxies at the edge of the universe

Astronomers promised a glimpse into the edge of the universe and didn’t break it. The edge of the universe has been viewed by the infrared space telescope.

and he James Webb Space TelescopeAnd the telescope sent to Earth images of the most distant and oldest of the four galaxies that appeared among the first galaxies in this remote part of the universe to which the telescope was directed, and there does not seem to be anything more distant.

According to the “RT” website, for the first time, scientists were able to see galaxies that formed only 350 million years after the Big Bang. It’s fantastically far away, said astronomer Brant Robertson of the University of California, Santa Cruz. Undoubtedly, the distance was determined correctly.

“By analyzing the telescope’s radiation spectrum that was captured, we realized that the detected galaxies are not imaginary, but in fact at the edge of our vision, that is, a little further than what was seen by the orbiting” Hubble ” telescope,” said astronomer Emma Courtesman, from the University of Hertfordshire in Britain. She noted that this achievement is very exciting.

She added that those distant galaxies correspond to the red deviations “10.38”, “11.58”, “12.63”, “13.20”, and the latter is equivalent to a distance of about 13.5 billion light years. This was officially confirmed.

The Big Bang, which marks the beginning of all things, occurred 13.8 billion years ago. Since then, the universe has expanded and its firstborns have moved away. And when watching them, astronomers plunge into the depths of the past, like archaeologists dig into the soil. And they see what happened when the universe was a newborn, but it seems rich in events.

It is now believed that, before the birth of the first stars, the universe was filled with opaque matter and its molecules gradually coalesced, forming neutral hydrogen. As for the emerging stars, they ionized the hydrogen and made it shine.

It is worth noting that the “James Webb” telescope operates in the infrared range, where the sensitive camera (NIRCam) captures rays from distant space objects that reach us in a distorted form. As a rule, it is shifted to the red region of the spectrum. This phenomenon is called “red shift”. It arises as a result of the expansion of the universe and the distance of galaxies from each other. The farther away a galaxy is, the faster it is receding and the greater the redshift.
