Just think. We've got at least another 12 years of JWST observations. This telescope is truly knocking it out of the park for astronomy.
Lol space is fake goofball
Clearly it's not. Your head has nothing in it.@@elka7823
@@elka7823 hahah so funny
Just imagine rolling the dice with ten billion dollars on the line. That is how James Webb Space Telescope do. If we don't find Marvin, I want my money back.
@@Somethinghumblethey delayed it prob ten yrs to begin with. We should have way more info on systems and how they move.
340yrs ago 😮. Wow
My initials are CAS
340 years ago light reach to earth ... So just think about it how much light years away from our earth ..... Mean when we evolving this thing happened.... And now this light reach our earth
"estimated that it exploded 340 years ago as seen from Earth" That's just a weird way to phrase it. If it's located 11,000 light years away, when did it really explode? 340+11,000=11,340 years ago?

One light year is a unit of distance, not time. It represents the distance that light travels in one year. The speed of light is approximately 299,792 kilometers per second. To calculate the distance in kilometers that light travels in one year, you can use the formula:
\[ \text{Distance} = \text{Speed of Light} \times \text{Time} \]
So, \(1 \text{ light year} \approx 9.461 \times 10^{12} \text{ kilometers}\).
It's important to note that a light year is a measure of distance, not time.
goot to know wery useful for me :)
Go, Webb, go!
Another 20 years!
Calling something an “object” that is 13 light years wide is messing with my precepts of scale big time.
it is object bc they can not see , should be academic correct
Black holes are still fkn with my head. The math says that if you pass the event horizon, not only are you pulled into the center (spaghetti like) but also space and time are sort of inverting so your experience of time also spaghettifies and approaches infinity like your mass. It's also a big hollow space with the singular point inside it being where all the dense mass was/still is/exited through a corresponding white hole somewhere/when else. Also Hawking proved black holes are emitting a type of radiation and therefor will eventually reduce and disappear. Talk about one wild ride.
Beautiful and very informative. Thanks Webb!
1:13 thanks for highlighting! I would not have easily noticed those, even with the well done narration! 😁
This is so cool!
Thanks for sharing.
I never thought of a shockwave outpacing the previously ejected gas...
Such an overwhelming number of details to consider!
Exciting (and daunting haha)
Truly Amazing!
Jaw dropping Wow, 340 earth years ago, that's so just happened amazing, thanks for share ❤
I'm confused - the narration says that this massive 'object' is located 11,000 light-years away - but it also only 'happened' 340 years ago...
Would I be right in saying the LIGHt from these objects only ARRIVED on Earth 340 years ago???
Sorry - amateur autonomist here : /
Yes@@sprinkdesign7170
@@sprinkdesign7170yes, the supernova was visible for people living on earth 340 years ago. Probably they've seen a bright star that was not visible before and then it disappeared a few days later...
Itd take roughly 16.75 Million years (give or take) to get there. It takes light 11,000 years to get to here. The vastness of space is mind-blowing.
Edit: via modern spacecraft
Nerding out, which technology do you think might come first:
Generational ships where descendants reach the destination?
Or
Some kind of hibernation system?
:)
@@TragoudistrosMPH definitely a hibernation system as you call it. I don’t see interstellar travel possible for humanity, at least for us being on-board. It would take about 6,300 years to reach Proxima Centauri in a spacecraft moving 5 mi/sec., given the star is roughly 4.2465 light years away.
I believe that reaching the outer planets in our solar system may be possible in the next 100+ years ( maybe many more ) if spacecraft evolves to travel at speeds feasible to make it there within a few years. You gotta think that even spacecraft moving at 20 mi/ sec would decrease the amount of years to get to Proxima Centauri, but that’s still 1,575 (give or take) years then. Betelgeuse (in Orion) is hundreds of light years away from us, so imagine that!
All in all, I firmly believe that it is possible to further innovation and technology to achieve such a task as our solar system being explored. However I do not think that will come in our lifetime. Nor do I think it’s going to be possible at all travel among the stars.
Even though we’ve made so much progress in the last century with everything to medicine, technology, etc., I still think there is quite some time ( if at all, any) before that could happen.
The last two things I’d like to day is that: given stars are that far apart and away from Earth, the only possible scenario would be NASA (or whoever in the future) sending out something to travel interstellar. Even then, it’d take thousands of years for the FUTURE after that to even get data back to us humans. Lastly, because space is expanding faster and faster, galaxies are moving along with it at high speeds, which means you’ll just never catch up to see a star.
This is always mind-blowing
That was amazing!!!
Stupendous. JWST is such an an impressive set of instruments. However lets not forget the team behind putting this technological tour de force into space but also the folk processing these images. How much satisfaction can a job give you? I'd love to be working on this stuff. Maybe in another life..
After these pictures it’s hard to say that we are alone in the Universe!
Mathematically, we cannot be alone in the Universe. And, you're right, these images add credence to the math. Pretty cool, in my opinion! 🖖
❤ Beautiful, amazingly beautiful ❤

Yes!! 💫
❤ you JWT
Thank you!
Amazing
There's a point in my career in my work with keck that granted the win for the virtual release of SRB-8 that launched CAS-A after STS 112b at the pad.
340 light years , 17 lightyears across … so 15,000km/s expansion .
Very very nice
I would have liked to have gotten an idea of where it actually is, in the Sky. Your image needs some context, I feel.
Beautifull cassiopeia, good nice James Webb Space telescope.
The dark voids are caused by minute fragments of what? The star? Or debris in orbit around the star?
Do galaxies spin clockwise or counter clockwise, or both? I wonder what causes it to spin besides gravity.
(JWST) Just Wonderful Space Telescope
Are the six-point star shapes an artefact of the hexagonal mirrors on JWST?
Yep! That and the struts.
Dr Becky has a CZcams short that goes into quick detail on hubble, JWST, and Euclid artefacts!
Longer vids exist for a more paced explanation
I love it
The universe. ❤❤
I still think we are in same time! Can you ever dream of seeing future. Everything is now! The present is the gift! Peace
76 trillion miles across.... can't even.....
Oh my god 😢
Excellent
What is this interstellar medium you speak of . . .
Oh oh do ic-1101 next I wanna see ton 618 ... I don't care the
At she isn't the biggest anymore. I still love that Galaxy
We should get pics once a week with the tech we have.
That's about how often we do.
This light reached us 42 years after Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 - 8 January 1642) had died in condemnation from the religious moralizers of his time. 🧐🖖🏻
So the reflection is a hundred seventy ly behind. That means we are seeing light that came from the supernova 340 years earlier when it first blew up.
How about a video on JWST study of planets atmosphere looking for markers for life. Anything else is not really pushing forward what we know today
It's going to be a year or two before we start seeing that kind of stuff. Taking single images of bright milky way objects only takes a short time. Whereas spectra on Earth sized planets will take dozens if not hundreds of runs to stack all the datasets to filter out the noise and get clear results. I'm on the edge of my seat waiting for this bit too.
Wish they took requests. But Hubble didn’t. Sooo. I’ll just throw it out there. NGC 7510. I’d like a better look than what I can find on the internet.
❤
please post these kind of images and information about it everyday
hey space nerds :) given the tecnology ( faster then speed of light or something) could we watch a super nova explosion at a safe distance ??
Tough question since it’s theoretical
this is insane!!!!

I'm kinda confused. If the explosion happened 340 years ago, then wouldn't the light from that explosion take 11,000 years to get to us? since that's the distance between the earth and the CasA?. Can someone please explain? Im dumb :p
I hope this helps: Cassiopeia A is thought to have exploded 10,000 years ago. The light from the explosion was finally seen on Earth 340 years ago, not 340 years *after the explosion.*
Beethoven died almost 200 years ago. If you're just now hearing about, it's not because it took 200 years for the news to reach us. He died two centuries ago. You're just now learning about it, 200 years after the fact.
Some cutting and pasting:
"The light from the exploding star reached Earth 320 years ago. ( . . . )." Cas A "resides 10, 000 light-years away (. . . ) so the star actually blew up 10, 000 years before the light reached Earth in the late 1600s."
It took me a while to understand how that works.

Real time 11,340 years ago from today is when it happened.. they are talking that the light finally reached us 340 years ago
That was nicely explained!, Thanks a lot, Relly appreciate it man! @@TheStockwell
got it!, Thanks a lot for the reply. :D@@nervani19tft93
@@likhitnamdar4985 I read your question and thought, "It's simple. Because the explosion is, um, no. Wait. If it's that many light years away, then logically the light took - damn it! I'm confused, now!"
I had to look it up on several websites before I found an explanation which made sense to me.
Anyway, happy Frank Sinatra's birthday! 🥃🐧
that however was not my question
Cassiopeia eh!
Why dose the James web leave lines in stars like normal telescopes sure this is James web actual make this image
where are the newly discovered planets, thats what im more concerned about😫
Why do deep space objects appear to never change?
They do! Remember how we found planets with Kepplar? We waited to see planets block light from a star.
Far away, details are hard to notice. Up close (or zoomed in), we can see the changes. :)
It's worth mentioning that most stellar evolution takes millions or billions of years. So, from our human perspective, it seems like most objects in space do not change.
It looks like a right mess
Anybody else 👀 see the 😈 demon face in the shot @ 2:16 / 2:46

The left over tech from our draconian, world-spanning spying and intercontinental ballistic nuclear missile program sure is cool!
Bruh. Facts.
Yet this is one of those innocent, internationally cooperative things that brings a sliver of hope... to some of us.
Paz y luz 💫
The technology was developed specifically for this mission - it's not "left over tech" from whatever you think it comes from.

@@TheStockwell... actually, the person isn't wrong when looking in the larger scope.
Unfortunately, military applications develop much of our technology
HOWEVER you are correct to point out how scientists explicitly planned and pushed the envelope to make this outstanding machine a reality.
Neither aspect should be neglected :)
(It's a great reminder that if budgets were reversed, we'd have hundreds of telescopes and a few 'amazing' weapons.
I just looked it up Jwst $10 billion
Latest US carrier by Ford $77 billion projected but $120 billion is now expected...
We have 11 of 21 carriers on Earth... )
Edit JWST was 10 not 13 billion (more depressing)
If i may try a different slant on this. If the US did not have a powerful and sometimes aggressive military you might have other more populous nations and their domestic US acolytes, diverting you from space science / astonomy. You could possibly end up feeding the hungry millions instead thereby exacerbating the population crisis.
@@TheStockwell uh huh. Shall we compare lists on tech it used that were developed under DARPA and other Pentagon programs with whatever it is you imagine was developed for whichever mission it is you're on about? I bet if we compare the tech to that being used on Palestinians right now, we'd find a lot of overlap. There is nothing the US does with "space explorarion" rhat isn't tied up with weapons manufacturing, and international theft..
I can’t believe this is a real picture.

Most men's games are associated with "hitting the target" (football, hockey, billiards, basketball, etc.). It seems that there is something with innate instincts, and maybe sexual - purposefulness is attracted by emptiness (a gate, a hole). And here there is such a huge void (the Universe), and even with a lot of black holes... It looks like astrophysics has a great future!... Well, about the growth of the "intellectual potency" from man to humanity - see from the DrSci: "Biophysics of Evolution of Intellectual Systems" // Biophysics, 2022, Vol. 67, No. 2, pp. 320-326.
