Furtherest Known Galaxy Discovered by JWST

The previous oldest known galaxy is GN-z11. Discovered in 2015 (with a redshift z=11.09) it was formed only 400 million years after the universe came into existence at about 32 billion light years away. The shot that discovered this galaxy took a few months to produce from a Hubble deep field shot.

This recent discovery took 12 1/2 hours from the new James Webb Space Telescope (JWST).



Designated GLASS-z13 (a redshift of about z=13) it formed around 300 to 400 millions years after the universe came into existence, about 13.5 billion years ago.

If JWST can pick up in a few hours what it took Hubble months to discover, imagine the discoveries when it starts taking deep fields at lengths that Hubble was doing.

woah that is pretty close to the edge of creation, I wonder if we will be able to see the the creation of the universe at some point.. we are getting pretty close, I wonder what is the limit.

I hope life have spawned in closer to earth, 32 billion light years would take some time to travel by rocket.

They spare no costs and efforts to maybe find intelligent life somewhere in that maybe endless space because they weren´t able to find any intelligence on earth before.
Cheers

I really love the new JWST!!!

Fred..

I see a smaller, fainter one to the left, is that further away?

I think it's like looking at a firework display through the smallest fibre optic and going "ooooh!".

There will always be more, and more, and more beyond anything we can ever view in the blip that is the human race.

That applies to viewing into space and looking through microscopes too imo.

One day they are going to discover that they are looking at the back side of the objects they are pointing at.

in view of the dimensions, the unimaginable distances, the question arises why all this? for what purpose? just so that somewhere in the universe, on a tiny blue dot, people bash each other's heads in all day long? that would be pretty sad. on the other hand, we are able to discover such galaxies. but i can't imagine that all this is just for us and because of us. actually, there should be a lot of life out there. maybe some day we will learn... maybe it would change us for the better.

It might not be able to pick up as 'nice' of pictures as it did before, It was damaged.

Huge Setback for JWS : seriously damaged

The most advanced space telescope by NASA, James Webb Space Telescope has suffered massive damage from asteroid strike. Webb Space Telescope is made up of precious technology and carries one of the largest mirrors on a space telescope to observe phenomena and events in space previously inaccessible to us. And to fulfill the ambition, it is required that the JWST remains operational and continues to take images for years to come. However, concerns are being raised over the longevity of the project after it was revealed that an asteroid strike to the space telescope in May might have left it in a worse shape than previously understood.

So all the pictures they are actually releasing are kinda on the old side. I think it also affected the image quality being sent, granted they haven't explained how much damage was actually done to the mirrors and how it actually affected the project or it's lifespan. But apparently it was big enough to notice a drop in performance or quality, and perhaps even gone offline/signal. They think the next hit will take it offline permanently. Currently it can still take some pictures, which is a good thing. I think it would of been a devastating blow to lose everything at once. But what I don't get is why they didn't 'coat' those mirrors or at least seal it in a gorilla glass or plastic to make it tougher..

They claimed they could not put it inside the ship, but I'm sure there would have been other ways to protect it.. even if they would have built a cage/shield that activated off sensors i think they could of still done something to provide protections to it.. Even something like a self folding/collapsing panel could of at least provided a protection especially if it was meant to take impacts and operated off solar, power wouldn't of been an issue.

Especially when you can consider they are working on self driving cars that apparently is suppose to predict any and every variables from kids playing ball, to animals dashing in front of you. I'm pretty sure they could of done literally anything to account for 'rocks' or shapes of any type to activate it's sensors. So literally no excuse, given those car projects have come a huge way.

And the "backside" is that of the observer in red shorts.

We won't be able to see the moment when the big bang happened as the light never existed for another 380,000 years. pretty damn close though.

No. You won't be able. Never. But worry not: nobody will. You can only see the Universe that is visible to you. 93 billion light years is the observable Universe, the one whose light will reach you, in case you are still around by the time it reaches you. But that's not the Universe: it is just the observable Universe.

I wonder what is the limit.

The entire Universe is believed to be 275 times larger than the observable Universe. Certainly more than 6 trillion light-years in diameter. This means all you will ever get to see will be just a small portion of it. But even such a small portion is enough for you to enjoy the beauty of the design.

I wonder what that "275 times larger than the observable Universe" means, what define it as universe.. stars, planets, galaxies and such.. How did they get such a specific number, what happens past that.. is the universe expanding in such the 275 times larger becomes 276 larger soon, my head hurts thinking about what it is expanding into

Man it would be such a mind # to one day look so far into space that we see earth from the past.

a reply to: loufo

What if in an infinite universe there are trillions of planets with life like ours but it's still rare. And because of the nature of infinity the planets could be so far apart from each other that the laws of physics negate ever perceiving each other.

The mirror has to be on the surface and bare. Any coating or glass on the observing side would distort the immage.

How exactly are you going to detect a single speck of black sand approaching at a million miles per hour for enough out to do anything about it?

I think the next one should be made with extra mirrors and be able to swap out the damaged ones itself. Even if it could just jettison the damaged ones, it would improve the immage by removing interference caused by the damaged mirror sections.

Perhaps making a backup layer of mirrors under the primary. hmm ?

The telescope was built with the knowledge that it would be hit often by micro-meteors. Basically the mirror was made better than it needed to be to give them a buffer. But the size of the meteor that hit it concerns them. They don't know if it is a one-off or will be a more regular event than they anticipated. If there are more of those sized meteors then the life span will definitely be shorter than what was intended. For now they can adjust an compensate.

The farthest observable object from Earth corresponds to the oldest object given the speed of light. The important thing to remember is that distance and the speed of light are tightly connected.

However, the size of the universe depends on other parameters, among others its shape and expansion rate. It also depends on how and what are you measuring. Assuming the Universe is 13.8 billion years old it means you are located at the center of a sphere with a radius of just 13.8 billion light-years: that's the observable Universe for you, now, which means the total diameter of the observable Universe for you is about 28 billion light-years. There are objects beyond the sphere, but you cannot observe them because, as you see, the light from those objects have not have time to reach to you. This works the other way round, too: you cannot be observed by the guys outside your sphere.

If we take into account the fact that the Universe is expanding, then it is a matter of knowing the rate of expansion (a non-trivial computation) to arrive at the real size of the Universe. Depending on what rate you choose, estimates give you a current accepted average value of some 93 billion light-years. But note this is just an average value assuming expansion rate is constant (which is not) and depending on what observable you choose to measure. Apparently, averaging out all those factors the results show your Universe could be some 240 to 280 times larger than the observable universe.

But do not despair. Perhaps the question is not how big the Universe is, or why is it so big, or how it came to be that big, neither how old it is, nor for how long will it last. Perhaps the correct question is this: how many times can it be?
