For the first time, six objects belonging to the ancient universe appeared before the eyes of the inhabitants of the Earth through the extremely sharp lens of James Webb, the most powerful space telescope in the world.
It is 6 galaxies belong to the first universe, existed about 10 billion years ago and may have been completely destroyed or be just a “dry corpse” by now.
According to Sci-News, A research team led by Professor Shardha Jogee from the University of Texas at Austin (USA) searched the huge data warehouse sent by the James Webb Space Telescope and at the same time identified 6 unprecedented cosmic monsters. ancient world, when the universe was only about 25% of its current age.

These galaxies are located between 8.4 and 11 billion light years from Earth.one of the most distant objects ever observed by mankind, appears very clearly and brilliantly in James Webb’s image, suggesting that it was observed at a time when “youth”.
The distance of 8.4 to 11 billion light years also means that light takes that long to reach Earth. what we see is the image “time travel” the past not their current image.
It is possible that many of them no longer exist or have long since stopped forming stars and have become stars. “dried carcass”a ghost as transparent and translucent as some “scary galaxy” aging was observed in closer space.
The image was so clear that scientists even discovered “star bar” – a long band created by stars, extending from the center of the galaxy to the outer disk.
“Stellar bars play a central role in galactic evolution by efficiently redistributing mass and momentum, driving gas flows in the Galactic Nuclear Circle region through gravitational torques and shocks.” – explained Professor Jogee.
These starbars are like an express train carrying raw fuel to the center of the galaxy, helping to form new stars at a rate 10 to 100 times faster than the rest of the galaxy, in addition to contributing to the formation new stars. supermassive black hole at the center of the galaxy.
Scientists filtered these 6 bright cosmic monsters from 348 potential first objects in the James Webb database. Some of them were discovered by the Hubble telescope more than 30 years ago, but the star bar could not be seen because Hubble’s viewing ability was far inferior to that of James Webb.
James Webb is the main telescope operated by NASA, supported and operated by two European and Canadian space agencies, ESA and CSA.
The so-called discovery “shake” scenarios of galactic evolution, and also suggest what happened billions of years ago to vibrant, massive galaxies like the one containing Earth, the Milky Way.
The research has just been published in a scientific journal Letters from astrophysical journals.
