JWST Just Found a Galaxy That Is So Old and Extreme That It Is Like a Fossil from the Early Universe

In this episode, we will explore one of the most remarkable discoveries made by the James Webb Space Telescope (JWST): a massive and compact quiescent galaxy, which is a type of galaxy that stopped forming stars and is a possible ancestor of giant elliptical galaxies. We will also learn how this galaxy is surrounded by a complete Einstein ring, which is a rare and spectacular phenomenon of gravitational lensing, where the light from a distant galaxy is bent and magnified by the gravity of a closer galaxy. This discovery is not only stunning to look at, but also has profound implications for our understanding of galaxy evolution and cosmology.

"A long time ago in a galaxy far, far away..."

[reluginbuhl]

It's a real privilege to live in the period of human history when we are able to explore the universe with such amazing technology!

[jansugalski]

This video does not mention the fact that if the universe is much old than 13.8 billion years, which is now taken seriously, this galaxy did not have to quickly stop star formation, because it could be much older than 13 billion years.

[foxcalledneoii]

We could potentially be more open to the possibility the universe didn’t start with a ‘big bang’.

[whatdadsees]

Assuming the universe is static. No one knows how old the universe is or its size. We only know how far our present technology allows us to see. The pictures are fascinating.

[kbnikto]

JWST. It just keeps getting better and better ! What a time to be alive!

[aleleeinnaleleeinn]

I guess astrophysicists don't have any problems changing their minds when provided with real evidence.

[larryyoung]

While I question some of the inferences drawn, this is brilliant science. JWST has expanded by a quantum leap, humanity’s ability to see what exists deep in the past of our universe.

[PenelopePitstop]

So fascinating. I'm no rocket scientist but I love learning about space❣

[gd]

I've said it before and I'll say it again: the universe is a lot older, a lot larger and a lot stranger than previously thought!!!

[renesoucy]

Strange to consider the Milky Way as a baby galaxy, awesome.

[lwdp]

What if this is a time warp and we’re seeing the future, maybe the Milky Way. The universe is weird.

[darrenl]

Great to see a video that explains things in simple terms that I can actually comprehend

[timmyjones]

This video is really awesome finding such a very distant galaxy that changes theories on how old the universe is and challenges the Big Bang Theory.

[skontherck]

Remember the universe is under no obligation to make sense to you. So far, I think a bunch of extra smart primates a few genes away from chimpanzees have made a pretty good start at least.

[proveritate]

Mankind on earth STILL really knows nothing about the very distant galaxies ! Astroscientists guess there's over 500 billion galaxies. And life out there ? They guess and speculate and theorize !. It's a dark enigma ! Totally obscured from us atm !

[DrReinerHutwelker]

Outstanding - the finding, explanation, storyline, and narrator - I like this series very much - thank you - One question: Would we find similar galaxies in the exact opposite direction?

[farhadfaisal]

Just assuming an older universe is not enough, you have to account consistently for other data such as the Hubble constant and CMB radiation spectra etc.

Another possibility to consider is a drastic revision of the current one time Big Bang like cosmological model by something like a cosmology of cyclic phases or eons, of which ours is obviously the current phase, that might have left some signatures of a previous eon, a la, for example, the conformal cyclic cosmology of Roger Penrose.

[lauriefox]

Thank you so much, I learn, the images are outstanding, and the music is soothing.

When they make an even newer and better telescope, they will rewrite everything about the cosmos again
