According to ESA scientists, the light recently detected by the James Webb Space Telescope has traveled 13.4 billion years.

The James Webb Space Telescope has looked back further than ever before to see the most distant and oldest galaxies on record. According to the European Space Agency (ESA), the light from these galaxies has traveled more than 13.4 billion years to reach Earth. The scientists are preparing two publications of the findings.

Scientists investigated the redshift of light detected by a telescope. We can talk about redshift when light travels for a long time in the universe, so the expansion of the universe shifts its wavelength in the red direction of the electromagnetic spectrum.

The James Webb Space Telescope has used this method since its inception to detect light from ancient galaxies. During the current observations, European Space Agency (ESA) scientists measured the redshift of the light and found it to be on the very edge of the spectrum.

According to them, the observed galaxies existed when the universe was younger than 350 million years ago.

Hulk has discovered a total of four new old galaxies. These are JADES-GS-z10–0, JADES-GS-z11–0, JADES-GS-z12–0, and JADES-GS-z13–0, he says Interesting geometry.

Using spectroscopy, the scientists showed that hydrogen and helium were present, but heavier elements such as oxygen, carbon and nitrogen were absent. Old galaxies are known to be mostly hydrogen and helium, so they can rely on that to make sure they actually see one.
