Galaxy z8_GND_5296 is the most distant ever discovered ...


An international team of astronomers has detected a furthest galaxy ever discovered.
Astronomers say that the newly discovered galaxy is 30 billion light years away from the Earth. The distant galaxy is named as z8_GND_5296.

The Universe is expanding and everything is moving away from us. So, light waves are stretched. This makes objects look redder than they actually are.

Astronomers rate this apparent changing of the colour on a scale which is called redshiftThey found that this galaxy has a redshift of 7.51. This is a record holder redshift that beats the previous which had a redshift of 7.21.



Galaxy z8_GND_5296 formed stars at an incredible rate, about 330 per year. which is more than a hundred times faster than our Milky Way galaxy.
The astronomers believe that the light came from the galaxy, shows it as it was 13.1 billion years ago.






z8_GND_5296 is also turning gas & forming stars at a very fast pace, pumping out about 100 times more stars than the Milky Way galaxy, so it may be brighter than the other candidate galaxies.
It contains a surprisingly high percentage of elements heavier than hydrogen and helium.
Scientists said that, Those elements are forged by nuclear fusion, so either the galaxy contains the exploded remains of lots of massive stars or it formed in a region of space that had been previously seeded with the remnants of a prior generation of stars.
