You were probably already rendering and uploading the video, but that Pillars of Creation photo released yesterday was breathtaking. So emotional too since it was my favorite hubble picture and such an iconic image. Nebulae are truly my favorite.
Yup, we're working on the Space Bites episode now, it'll be in there.

You are my #1 JWST News Anchorman! Thanks for all your passion. Greetings from Germany
Hi Fraser , i dont comment much on any youtube videos , i started watching your channel because i was interested in JW pics, but i find your videos and explanations and overall updates on whats going on in the world of space to be absolutely fantastic, keep up the good work and u have a real gift at presentation that speaks to all walks , thank u .
THE PILLARS OF CREATON PHOTO LOOKS LIKE THE NAME OF GOD IE ALLAH IN ARABIC.
Just in case anyone's wondering; he meant to say 30 *million* light years when referring to the galaxies webb photographed. 30 light years is still within our own backyard :)
Yeah, 30 million. 😀
I’m so grateful I found your channel. 😊 you talk about everything I wanna know about and you put it into terms I can understand. Not many channels like this one. Love it!!! ❤
Oh great, I'm really glad you're enjoying it.
@@frasercain more than you can know. Cuz I usually get stuck and lost into unsolved mysteries on TH-cam and eventually that content can affect my psyche in a negative way. Your just a breathe of fresh air and I have ALWAYS enjoyed anything when it comes to beyond our world. Keep it up!!
@@frasercain My favourite TH-cam channel. And I LOVE TH-cam. PS You didn't mention the giant luck dragon smiley face on the right half of the JWST Carina Nebula image!

@@frasercain constructive criticism:
The information you are conveying, and your narration of the topic are superb.
Lose the background noise!
You added some kind of noise track and it is VERY distracting and annoying.
For me it is unbearable.
Fantastic video Fraser. With discoveries and science happening all the time (and not just with JWST) it's nice to have a "this is what has been done/discovered so far" video. Thank you so much for putting all of this into one place!
yesterdays release of the pillars of creation was absolutely mind blowing. by far the most amazing shot so far.
Released during my 19th birthday lol.
Thanks for the update. JWST's discoveries are definitely worth the money and effort.
Amen
I aint seen anything different from what hubbles been putting out for years.
@@davehoward22 Hubble can't see near as far because it has a smaller mirror. Hubble also can't see through dust (using infrared) to find planets and stars. JWST can see all the way back in time, over 13.6 billion years ago, to about 180,000 years after the Big Bang. It's hugely important. It's not necessarily about what you can see, it's what we can learn. So far, we're learning a lot.
@@davehoward22 then you don't understand what you're looking at. It's not just about "pretty pictures" though that helps with public support for this tax based science missions

That reflection animation at 21:39 BLEW MY FRIGGIN MIND! Holy hell that's complicated, that has to be so precise, so well engineered and designed O.O
Yeah, these engineers put my amazement in the feats of "the Woz" to shame! The JWST is truly astonishing...!
Great overview Fraser! Thank you.
Very good delivery ! I was hooked at every and each of your sentences :)

Just found your channel. Fantastic! I sure don't understand a lot of what you are saying but my grasp of sophomore Astronomy in colllege many years ago helps me appreciate the vastness of this new knowledge.
I look forward to the next Web news and pictures.
Thank you Fraser! Recently you responded to people who felt 'disappointed' by Webb. I feel similarly not because I expected high res images of E.T. - I was just expecting that for the first few months JWST would dominate all space news. Every time a space video showed up on my feed and it wasn't about Webb, I just felt confused 😅 but I know that scientists are working over time interpreting the data, and I just can't wait to get into the meat of the insights. Anyway, thanks again :)
Great video!
Glad you enjoyed it
Great content as always. So cool that we get Webb for x2 the planned operational time. Cannot imagine all that can be done if Webb can observe the Hubble Deep Field in a few hours (took Hubble 10 days). Thanks for a detailed but not too technical channel. Perfect balance.
Thanks a lot, I'm glad you're enjoying them.
This channel is amazing. I really enjoyed it. Thank you so much. I will watch it whenever you come on. Bless you!
Thanks a lot! I'm glad you're enjoying it.
Thanks for the video! :)
Fantastic content. Thanks Frasier.
Absolutely fabulous mind bending amazing reporting
I love your channel...it's concise, interesting, and your updates on the Webb, instant. To be honest, I was going to complain about its high price tag of around $10 billion over a 24-year span then I thought it was really not that expensive considering our national budget of $100 trillion over the same period plus the Webb project kept many scientists employed. Keep up the good work and thanks...
It's about the price of one aircraft carrier.
Great video. Thank you very much
Excellent video on JWST! Thanks Fraser 👍🏻
keep going Fraser greatest place for keeping track of what is going on
I like you very much
I love the clarity of the pictures!
All I can say..
I love you!!
You are by far the best teacher/ explainer of all things complex! You just rule. (And also, the crush prevails!) Xo
Excellent video! Plz consider doing a jwebb update every few months, or so
I've been learning a lot! Thank u
My favourit part are the solar system observations, because they feel more relatable to me. (Though the rest are beautiful and if their science is explained well can also be relatable).
Hi Fraser, great video!
I have a question: why don't they send another JWST to the spot. Pressumably the biggest cost went R&D in design and manufacturing. Now that we have that knowledge, wouldn't the next one be relatively cheap?
Cheers!
I would say that webb has been surprisingly better than expected; I kind of wrote it off long before it launched, thinking that it was doomed.
Pleased to be so very wrong. Webb has been one of the best things about 2022... Which has otherwise been a really crappy sequel to 2020, like 2021 was before it.
War, recession and depression, more plague and regional famine as prelude to truly global cascading disaster.
Thanks for this
Cheers, Anton;)! good idea :D
amazing video thank you
i'm here for the exoplanets
Lots of exoplanet news.

Thanks! Welcome aboard.
Wow, that was a great update, Fraser. I can't even imagine what JWST will show us in 20 years!

@@kellysam2076 sigh
I believe that the James Webb Space Telescope can image from the near infrared to the mid-infrared , but not the far infrared.
Love your work sir
Slight "mis-speak" correction at 18:44. IC 5332 is 30 Million* light years away, not just 30 light years XD.
I'm really interested in "Galaxy Filaments" I hope we can learn more about that whole process.
Like strands/veins of tomato sauce in a stellate pattern around and in between vacuum-sealed meatballs. Same physics.
if webb would look at pluto or eris or other dwarf planets would you have more than 1 pixel of detail? i remember hubble could BARELY make up the color of pluto before new horizon got there
Hey Fraser, if JWST didn't have such a great launch and instead had a catastrophic 💥... How long and how much would have costed to rebuild it? Since the technology and all the blueprints are available, it should be just a fraction of the cost... Maybe we could think of JWST2, if JWST gets damaged a lot and becomes unusable, we could relatively cheaply rebuild and upgrade it a little...
Great summery !
thanks!
I subscribed!
It perhaps means the big bang itself formed heavier elements. Makes dessert to me. Mass was at that point extremely compressed fusing elements.
Just a hypothesis of mine. But ...I'm not an astrophysicist. I know physics, former NAVY nuke I better know some physics but...
Thanks for this great update!

Hi sir, thanks so much for wonderful video 🙏🙏. Could you pls make an video of how a telescope can get images from such a long distance in just hours and days time.
The light is no longer that far away.
Thanks
when will it take a picture of the andromeda galaxy?

Best news this week! TY
"You can imagine ... answers," but that doesn't mean they will; rather, more likely, they will have more questions.
New telescopes are question factories.
First let me say you are very good at explaining this and keeping it not overly geeky sort a speak. I have a question about the galaxies we are just now seeing is it possible they no longer exist and what we see is the ghost of them from billions of years ago?
They certainly do still exist, in some new form, but galaxies evolve quite a lot over time. They may have merged with other galaxies, or become larger and changed their shape, and most of the bright stars that we see in them would have died billions of years ago since they were short lived. Many galaxies have probably stopped forming new stars and become 'red and dead' elliptical galaxies, but many are like our spiral galaxy, slowly running out of star forming gas but still producing new stars at a slower rate and those new stars shine bright blue in the spiral arms.
Thank you for a clear and concise presentation! What a wonderful expenditure of tax money.
I have a breakthrough in cosmology and physics. Particles exist at the speed of light so gravity doesn’t affect them according to Einstein’s relativity. Instead of invoking dark matter and dark energy, do some thought experiments in general relativity and you will understand that rate of time and the measure of distance are relative to the amount of matter and mass there is in the vicinity. The speed of light literally depends on these two variables of time and distance.
As you observe a galaxy you are actually seeing differing rates of time and differing measures of distance. The result is that you are seeing differing speeds of light (because of the rate of the passing of time and measures of distance) relative to where we are since the measures of time and distance are both dependent on the amount of matter and gravity there is in the vicinity. (The speed of light isn’t actually changing, the measures of time and distance are changing *which effectively changes the speed of light as we observe it over GREAT distances.)*
The result is that distance is greatly expanded (not expanding) where there is no matter between us and distant galaxies (causing redshift) eliminating the need for dark energy and the movement of the outer spiral arms of galaxies is at a faster rate of time causing them to move faster as we observe them eliminating the need for dark matter. This also means that plasma jets shooting out from the center of galaxies isn’t seven times the speed of light. It’s that the distance is expanded and the rate of time is faster the less matter there is in the vicinity.
There is no such thing as a nonsensical infinitely expanding universe or an imaginary inflaton and there is no such thing as imaginary invisible dark matter.
Distance is *merely* greatly expanded between the black holes in galaxies (causing the redshift) so the universe is not infinitely expanding as is claimed. An infinitely expanding universe is nonsensical. Not only is distance greatly expanded where there is no matter between galaxies, time runs at a much faster rate where there is no matter.
Distances within the galaxies are vast so when we observe another galaxy, we are literally observing differing rates of time and differing measures of distance still within the limits of other galaxies, not to mention the *extreme* distances *between* galaxies where there is no matter to dilate time and distance.
That means the distances between the galaxies are greatly expanded, (not expanding) and time between the galaxies is running at a much faster rate *which allows for us to see fully formed distant galaxies in the first place.*
Great, public a paper in a scientific journal, get it peer reviewed and develop experiments to confirm your theories.
Globular clusters are cool.
What is the website at 22:17 ? Can find any mention of it in the description.
Thanks for the updates and info on one of Webb’s modes. It sounds like a minor problem now and assume it will eventually get fixed. As far as this telescope and it’s relationship to earth, distance from earth and is it in an orbit around earth? This all must have been covered earlier after its launch but I missed it. Is it’s distance from earth stationary? Since it has ample fuel It can move itself away from earth, or where ever it is. There’s too much here for us who know little about the universe to wrap our brains around because our minds are relative to that which exists on our own planet. Things like speed and distance and images of nebula that look like clouds in the sky. This also includes time travel. I have a hard time relating our own galaxy as small. Distant stars so huge they dwarf our own sun. Black holes that are terrifying but what do they do that makes them terrifying? If someone could compile an idiots guide to all of this it would be great.
Here's a video I did on Webb a few years ago: th-cam.com/video/TXiU1YxWyzY/w-d-xo.html
Hi Fraser, a question for you. How far away was what we observe as the CMB when the light was actually emitted, or when recombination occurred?
THE PILLARS OF CREATON PHOTO LOOKS LIKE THE NAME OF GOD IE ALLAH IN ARABIC.
Okay….. you launch a multibillion dollar telescope into space with an expected lifetime. You find out out after it launches, it’s lifetime is literally doubled. Now that’s a good day. If that’s not a good day I don’t know what is.
What if we send LUVOIR to the solar gravitational focus opposite of the direction of the most distant object Webb will see? What would we see? What about double or triple gravitational lens effect in a row?
A 1-meter telescope at that point would let us see a 1-megapixel image of an exoplanet. I can't even imagine what LUVOIR would do there. But you only get one target.
@@frasercain not if it is orbiting the Sun. Imagine LUVOIR at the Sagittarius A* gravitational focus.
Mr. Cain you have a soothing voice
24:40 existential crisis realizing that the instrument may survive longer than you do. At least I got one.
Blows my mind. Can't take it.
Just wait for what we learn in the next 20 years.
So space 🌌 is continuously expanding in all directions from what point? Where is the exact center of the universe? The sun is our star and there's billions of stars what makes our sun or planet the center?
@@NightmareDoesntLikeThis just like the rest of humanity you don't have any clue how many stars are out there, at best it's a guess, and billions does equate to any number higher than itself in this case, because it's just a "random guess".
There must be a cosmic horizon for the cosmic background radiation. I guess maybe we already can't see all of what once was visible from anywhere.
I wonder if what facilitated the creation of numerous stars early after the bang is the fact that the newly-created matter is physically closer, as the universe has had less time to expand. That perhaps "still warm" spacetime, from having just condensed heat-energy into matter. Perhaps exponentially increasing the rate of star formation.
Thoughts? Questions? Concerns?
I´m presuming that IC5332 is 30 *million* light years away, not 30? (@ 18:43)
30 light years is pretty close for a star, much less a galaxy :-)
It bugs the hell out of me how the subtitles say Fraser Kane. Other than that love the videos. I've been falling asleep listening to Fraser and Pamela for 10 years lol.
@ Fraser Cane "cycle 1 data"
I was unaware that telescope data from Hubble and James Webb is only available to the public after one year, is this correct?
Is this a matter of syndication or access?
I could be a little off on this so don't quote me but I believe it depends on why the observation was done. Like if a scientist has a proposal of something very specific they want to observe and it gets approved then the observational data is confidential for a year. But if the observation is just generic, like part of a sky survey or something along those lines, then it is available right away to the public. Again I could be a little off but I think that's how it typically works. I remember Dr. Becky talking about it in one of her JWST videos a while back.
That's exactly right. If you look through the Cycle 1 list, you can see that some have 12 months before data release while others are released immediately.
Re the distance to IC5332, I think you need to shift the decimal point about 6 places to the right. Hate it when that happens.😊
Yeah, 30 million light years
Is there a website where these (or some of these) research papers are publicly available? I probably won't understand any of it but I would love to take a peek.

Another great video. Up the irons |m|
Thanks, I'm glad you enjoyed it.

Yay!
Enjoy!
James Webb is gorgeous what a absolute powerful machine it's really a Beast ,but watching this makes me ask the question are we alone out here spinning on this blue rock we call Earth ? 🤔
I can assure you the first usage of JWST were for classified military purposes. Confirmed by one of the project directors on JWST, not from NASA, but Northrop.
But it’s great majority of its use now is for the scientific community (I think… because the guy wouldn’t tell me more lol)
It's logical, early in the universe more matter was compacted into less space, the temperature was higher, blue giants formed quickly and went supernova quickly. Time/entropy was higher in a hotter more compact universe, this explains the speeding up of early Galactic evolution. A hotter universe also increases the speed of light. The redshift is due to light slowing over time as temperatures cooled.
*I Was thinking a year already 🤔 that felt quicker than my first prison sentence!* 😂
I'm guessing all the juicy stuff will come in a year or so when the boffins start publishing. An exciting time to be alive, I feel like an armchair Magellan!
Exactly, once all the journal articles start dropping we'll get all the good stuff.
How do the pictures from Webb compare to ground based Telescopes?
@Fraser Cain When stars are created in nebulas, what happens to all the remaining dust and gas? I just recently read an article about the Eagle nebula and it mentions that all that dust and gas will be gone in a few million, maybe it was a few hundred million years from now.
@John Smith I guess I left out a few things by not mentioning the planets, comets, and asteroids. I had rushed my comment. Now, the Ort cloud helps make more sense. It doesn't seem to be visible from Earth though. From a nearby star system such as Alpha Centauri, would one be able to see any slight remnants of a nebula?
Please can you help us with website sites/ link where we can see pictures of exoplanets and stars? I'd love to zoom in
Stars and exoplanets are typically only one (1) pixel.
LOL your thumbnail looks like the skill tree to undecember a game im playing.
I want to know why the Webb telescope has not been doing extensive imaging and analysis on the closest star(s) to us? Alpha Centauri A and B and Proxima Centauri. All of these distant galaxies and exoplanets are just eye candy and won't lead to anything.
The relative nearness of the Alpha Centauri system makes it obvious that we should be really looking it over; now that we have the means to do so with Webb. If we were to send a purpose-built robot spacecraft beyond our own solar system, the Alpha Centauri system should be the obvious candidate. Assuming the robot's systems are all functioning upon arrival, it can recharge from one of the Alpha Centauri suns and begin beaming information back to us. That's assuming we've also maintained the legacy receiving systems able to handle the info coming across the 4+ light year distance. If nothing else, if the robot is even half the distance, it will be a lot closer than we are and can beam back very useful information.
Wild speculation here. Let's say we use a nuclear rocket to achieve 5% speed of light by the time the spacecraft gets past Pluto. I'm guessing at that speed it will take a century to get to A.C. No I'm not going to do the calculations! Obviously, in order for the spacecraft to maintain a permanent and USEFUL presence at Alpha Centauri, it will have to slow down. That braking could be done by deploying a solar sail trailing the craft. Assuming the AI can do its job, the craft will find an orbit most suitable for its survival. Using solar energy and ion thrusters, it will maintain itself there and send back information.
Yeah, communications will be effectively one way due to the time delay. If we sent instructions via a powerful signal to the spacecraft, we wouldn't get any confirmation for 9 years! But, the EPIC quality of such a mission would be worth it. Far better than eye candy that Webb is currently giving us.
I'm always indecisive if I watch the live show or the recorded and illustrated 🤔😏
This one didn't have a live show.
@@frasercain you are right, and thanks for answering, love all your videos 👏👏👏
JWST is not a "far infrared" telescope; it covers near-IR and part of mid-IR.
Does redshifting stop somewhere? Can light shift down to radio waves so we could "hear" distant galaxies?
No, whenever anything is moving, the light is redshifted compared to you.
Imagine what we would get to see if JWST was to look at the Homunculus nebula surrounding Eta Carinae
Does this mean that we may have to create a "Generation 4" type stars/galaxies? Having rather mature structures earlier than we thought, with heavier elements, may give us a whole new epoch to study.
Hello!!!
Morning!
If you get trolled for this video, look at the last SciManDan 'Flat Earth Friday' where Bob and Jeran from 'globe busters' have been looking into this video.
Nice nice niceeeeeee!!!!
