The Most Distant Galaxies Ever Seen

- Last month, one of the farthest galaxies we've ever seen was confirmed by the Keck telescope. Here we discuss this discovery and how it fits in with other observations of distant galaxies.
Here is a link to the Nature article:

Great work Tony, hope you are having fun
Great discussion. Very excited to learn more.
Awesome video guys!.
What led me to choose physics and astrophysics as a career was a very early fascination with compact objects (i.e., white dwarfs, neutron stars and black holes) and a burning desire to understand them mathematically. The best time in my life was when I, finally, achieved a working understanding of the mathematics of General Relativity and, later, Quantum Mechanics. It gave me the feeling that I was achieving an understanding of how nature actually works. Great video guys!
Getting setup now. See you at 3pm EST.
Good explanation of why things can be farther away then then 13.8 billion lightyears in this one! great video with good facts and great ppl.
looking back in time to just when the galaxies started forming, what is the estimated distance between these distant objects and does the distance between them still suggest that the universe is 13.5 billion years old. Shouldn't these be rather bunched up?
If Hubble took such an image in the opposite direction, would the galaxies still be shown as newly forming galaxies with an estimated age of close to 13.5 billion years. If so, how can the origins of matter be the same in all directions if we are existing within an ever expanding universe?
What do you guys think about the big crunch?
can you tell us what you think will happen when comet ison goes around the sun if it makes it will the earth go thru its tail
Good morning from Greece.i study and search themes like these in amateur way.one question please for the dear scientists.since the universe is so so huge are you believe that we are alone?i've heard so many different things.please someone answer me.thank you and a happy new year.
Why cant they operate both telescopes at the same time? Hubble and james webb?
If the universe was compressed until the big bang, how did the Galaxies get so much separation in the 700 million years mentioned after the big bang and how much further has the separation become in the time the light from the Galaxy took to get here? How far can we see in the opposite direction?
Research Cosmic Inflation. Alan Guth and Lawrence Krauss give some good talks about it that are available on TH-cam.
***** Another video on you tube I like is titled How Big is the Universe?
everything cycles..everything.
and..I don't think black hole's are holes either.
I Love Astronomy.
Hey, Tony! Hey, everyone! :D
I'm not convinced of the big bang or inflation. Seems that when we get greater resolution all galaxies are developed, seems that when the Hubble is trained on a dark patch of sky long enough numerous, formed galaxies appear. I think the evidence is pointing to a spacial infinite universe, only with a chronological beginning in anti-de Sitter space. Anybody for thinking outside the box? CBM should be increasing.
My point is we've seen these so called irregular star clusters interpreted to be undeveloped until subject to greater resolution.
I'm sorry but I don't subscribe to the whole Red Shift paradigm. Also the idea that the Big Bang came out of a singularity demands the singularity be in one place relative to the infinite dimensional preexisting space, you don't get singularities or quantum fluctuations out of nothing, Why am I expected to except incoherent concepts?
Nothing wrong with questioning the promoted assumptions. ( Do you have any videos up, or any papers? Or any recommendations? I'd like to see them).
There was this paper that was published about a month ago theorizing that our universe started when a blockhole exploded. Don't remember the details but it was very compelling and explained current unknowns.
We (they) know the universe is expanding because of the Red Shift and higher and hotter radiation measurements the further out they go.
PlntPeace How do we know that the redshift is due to expansion or due to gravity? Also if the CBR temperature reads hotter as we go out farther and further then the CBR would read lower for our galaxy and it would increase as we consider increasingly distant galaxies, making ours the center of the universe. If CBR would read the same for all galaxies then redshift is due to gravity, thus no expansion is necessary and we could find ourselves in a spatially infinite, overall static universe.
If we invented cameras that were millions of times better than today's and we traveled light years into space, could we then turn around and see back in time, maybe see who was Jack the Ripper or watch the death of the dinosaurs would this be theoretical.
Just gas? Are you so sure?
So, where are the aliens?..
You guys see far far away things but you can't take a good picture of a comment Wow everything's so funny to you.
More fact less I think .
talk too much
