Scientists have calculated the most accurate distance to the farthest galaxy in the universe. GN-z11 is estimated to be 13.4 billion light-years from Earth.
As astronomers point out, the farthest and oldest galaxy formed 420 million years after the Big Bang. Nature.
Same GN-z11 It was first recorded in 2016 With the help of the Hubble and Spitzer Space Telescopes. Scientists estimate that a cluster of stars formed 400 million years after the Big Bang. But with the help of the Earth-based Keck Observatory (USA) 10 meter telescope, a new distance from our planet to the galaxy was calculated.
“We looked specifically at ultraviolet light because this is the region of the electromagnetic spectrum in which we hoped to find redshift chemical signatures,” the scientists explained.
GN-Z11, which refers to the recent activity of star formation, has been described as a moderate giant with a young stellar population, a high-brightness galaxy.
It is hoped that more detailed observations will confirm the results obtained and describe the features of the galaxy in more detail.
