The researchers found the farthest thing available – a potential galaxy called HD1 which they estimate is 13.5 billion light -years away. It is 100 million light years farther than the largest galaxy today. GN-z11.
The HD1 is very bright in ultraviolet light, indicating the strongest activity in the galaxy. Therefore, scientists initially thought that a star star, or someone who casts stars at a higher altitude. But on closer inspection, astronomers find that the potential galaxy produces more than 100 stars each year – 10 times higher than normal stars.
Now, researchers are considering two new things to explain the amount of energy released from the galaxy. On the other hand, there is large black hole 100 million times as much as the sun at its center; It is the oldest black hole ever known. On the other hand, HD1 is probably home to some of the earliest stars in the universe, which astronomers have not been able to observe to this day.

“The first population of stars formed in the universe was much larger, brighter and hotter than modern stars,” said Fabio Pacucci, lead author of the study. publishing astronomer and astronomer at the Harvard-Smithsonian Center for Astrophysics. spoken in a language.
These stars, called Population III Stars, which are thought to emit higher levels of ultraviolet light than normal stars, can explain the brightness of HD1.
If the stars of HD1 are confirmed to be Human III stars, it will mark the first time these stars have been seen.
Astronomers saw HD1 during 1,200 hours of observation with the Subaru Telescope in Hawaii, VISTA Telescope in Chile, the UK Infrared Telescope, and NASA are currently on vacation Spitzer Space Telescopethen verify its distance with the information gathered by the Atacama Large Millimeter / Submillimeter Array (ALMA) in Chile. The team will soon be watching HD1 with The James Webb Space Telescope confirm their reckoning again, they said.
