Astronomers have discovered a new most distant galaxy yet called z8_GND_5296. This new galaxy is located at a distance of 30 billion light-years. Hubble Space Telescope is used to discover this new far-off galaxy.
However, its distance is measured using a ground-based Keck Observatory in Hawaii. The international team of astronomers analyzed its color to measure the distance. Apparently, galaxy looks to be 13.1 billion light years away, but it actually is 30 billion light-years far away from the earth. This difference comes because of the expansion of the Universe.
This new most distant galaxy "is helping scientists shed light on the period that immediately followed the Big Bang," according to BBC. Texas University's Steven Finkelstein, who is the leader of the research team, said, "This is the most distant galaxy we've confirmed. We are seeing this galaxy as it was 700 million years after the Big Bang."
The study of this new most far away galaxy is published in Nature by title "A galaxy rapidly forming stars 700 million years after the Big Bang at redshift 7.51." Finkelstein also said, "One very interesting way to learn about the Universe is to study these outliers and that tells us something about what sort of physical processes are dominating galaxy formation and galaxy evolution. What was great about this galaxy is not only is it so distant, it is also pretty exceptional."
