GN-z11: Astronomers push Hubble Space Telescope to limits to observe most remote galaxy ever seen

Astronomers have discovered a galaxy that formed just 400 million years after the Big Bang explosion — the most distant galaxy found to date.
Key points:

Galaxy GN-z11 is 13.4 billion light years from Earth Finding sets new cosmic distance record Galaxy formed when the universe was only 3 per cent of its present age

Located a record 13.4 billion light years from Earth in the direction of the constellation Ursa Major, the galaxy, named GN-z11, was first spotted two years ago in a Hubble Space Telescope deep-sky visible light survey.

Absolutely amazing. But who thought up the crazy name “GN-z11”. Galaxies don’t have names like that.

I was under the impression they all have numbers, even though some get fanciful names, the numbers are their correct coordinates and description.

and it isn’t 13.4 billion light years from earth but 13.4 billion years ago.

https://en.wikipedia.org/wiki/GN-z11

The object’s name is derived from its location in the GOODS-North field of galaxies and its high Doppler z-scale redshift number (GN + z11). GN-z11 is observed as it existed 13.4 billion years ago, just 400 million years after the Big Bang. Its distance is therefore widely (and mistakenly) reported as 13.4 billion light years.

in fact it is probably around 45.3 billion light years from earth

… was?

is.

the universe is expanding. we are seeing the light from this galaxy that it emitted 13.4 billion years ago. at that time it was 13.4 billion light years, in fact less but i can’t be bothered working out how the expansion has affected that distance, away from the earth, if the earth had existed then. it’s complicated.

ChrispenEvan said:

Well, we can see it.

X billion years ago, the object that emitted that light was X billion light years away. In the intervening time, space has expanded a lot.

we see the light that it emitted 13.4 billion years ago. the galaxy isn’t there any more.

mmm that it is. I do have the feeling though that the universe was expanding before the actual earth we know coalesced into existence

it was.

the universe has been expanding ever since the Big Bang happened.

Well that all seems a bit complex.

it’ll do your head in sibeen.

but really it is just a matter of us being so used to seeing something happen when it does rather than waiting 13.4 billion years after the event to see it happen. except some shows that people OS see now and we have to wait 13.4 billion years before we get to see it in Oz, unless we torrent or hula or whatever.

It is probably a bit confusing that a supernova is being seen say today and the light from it happened so far in the past.

Wouldn’t that be illegal and frowned upon?

The interesting part is that if you could see it the day it happened, you never would.

i think it is ok if you have a euro seedbox.

see marcus’ second post re the distance the galaxy was from us when the light was emitted and the distance it is from us today.

I imagine a number of its stars would have burnt out by now, wouldn’t they have consisted of a large number of the very first stars which had a quite short (relatively speaking) lifespan

Thanks CE

yep, it would be a pretty old galaxy with lots of supernova happening over its life, i would imagine. might have merged with another.
