An early hint of cosmic dawn has been seen in a distant galaxy

The galaxy found at the dawn of the universe is known as the former evidence Cosmic prevention, The time the universe turned on for the first time.

Following the Big Bang, he scattered the photon of the early hydrogen and helium gas, becoming somewhat opaque cosmos. For next hundred million years, when the stars began to shine, their light had been hydrogen and helium, to give free photon and become a transparent universe, although the exact time is doubtful.

Joris knows Used by the University of Copenhagen in Denmark and his colleagues James Webb Space Telescope (JWST) to study the galaxy named Jades-GS-Z13-1-la. The Galaxy Big Bang has passed 330 million years, making it one of the first known galaxies in the universe.

The ultraviolet lights of the galaxy suggest that it was surrounded by a bubble around 200,000 years of light, which can interact with the cosmic hydrogen of its star light. Seeing evidence at the beginning of the universe “beyond our wildest expectations,” says Witstok.

Michele Trenti At the University of Melbourne agrees that observations match the Cosmic Coverage Process. “It’s amazing and exciting,” Trent says. “I hope that ultraviolet lights emitted from this galaxy to reach Jwsta. We would expect to block the photon that will surround the galaxy of neutral hydrogen.”

The nature of small galaxies is not completely clear; It may be bright because there are many hot and young stars, or because of a powerful black hole. “This would be the first most popular evidence to be a supermassive black hole in the middle of a galaxy,” Trent says.

The astronomers have seen others later, with a similar bubble that is the most popular example of the galaxies, Jades-GS-Z13-1-la.. “It’s a reference,” he says Richard Ellis University College in London. “This galaxy tells us that there should be a while and when the galaxies began from darkness, he pushes again from the beginning.”

Jwst was able to discover the secrets of this galaxy, looking for quite a long time, about 19 hours. Witstok hope is that we will soon see other evidence for the cosmic shade. “We have some candidates,” he said. “We can find even more (back in time), or perhaps the most extreme that is achieved.”
