The James Webb Space Telescope was sent into space to explore the secrets of the universe and with its help, scientists have learned a lot so far.
This telescope of the American space agency NASA has discovered the oldest and most distant galaxy in the universe. According to one estimate, the formation of the galaxy named JADES-GS-z14-0 took place 29 million years after the Big Bang.
The James Webb Space Telescope also discovered some unique features of this galaxy formed at the beginning of the universe. This galaxy is huge and spans 1,600 light-years, while also being extremely luminous.
Light emitted from this galaxy was observed by James Webb’s mid-infrared instrument, indicating the emission of ionized gas.
Scientists believe that this gas may be a combination of hydrogen and oxygen, and this discovery is also surprising, as it is believed that oxygen did not exist in the beginning of the universe.
The scientists involved in the research in this regard said that all the results show that this galaxy is not like other galaxies. He said that it is possible that in the future, with the help of this telescope, experts will discover more bright galaxies that are even more ancient.
Earlier, James Webb Space had also discovered the oldest black hole in the universe. In November 2023, a statement released by NASA talked about the black hole that came into being 470 million years after the Big Bang.
According to the statement, the black hole formed at the beginning of the universe has never been observed before, which may be 13.2 billion years old. This black hole was discovered in a galaxy called UHZ1. This black hole may be 10 to 100 million times more massive than our Sun.
Scientists said that this is not the biggest black hole in the universe, but such a large size of a black hole formed in the early epoch is unusual.
