Called GN z11, the galaxy is observed as it was 13.4 billion years in the past, and owing to the growth of the universe it’s now more than 32 billion light years from Earth. This means we’re looking at it only 400 million years following the Big Bang, which will be seriously impressive.
The discovery of GN z11 will soon be released on March 8 in The Astrophysical Journal.
We see GN z11 at a period when the universe was just three percent of its present age.”
Because astronomers hadn’t thought it likely to discover something that distant in Hubble pictures, the galaxy, located in the Ursa Major constellation, is particularly intriguing. It was made possible by the high rate of star formation. That makes it quite bright, and let Hubble’s Wide Field Camera 3 to quantify the “redshift” of the galaxy.
GN z11 has only one percent of the mass and is 25 times smaller when compared to the Milky Way. But it’s forming stars at a rate 20 times quicker in relation to the Milky Way, which astronomers said was surprising to get a galaxy that formed shortly following the Big Bang,
As mentioned, this galaxy is pushing at the limits of Hubble, which is unlikely to discover any galaxies further away. But astronomers are anticipating that, together with the start of the James Webb Space Telescope (JWST) in 2018, they’ll have the ability to peer even farther back to the annals of the universe.
This new discovery reveals the Webb telescope will certainly discover many such youthful galaxies reaching back to when the first galaxies were forming
