It's nuts how much engineering is crammed into to this thing
It's just amazing how long we have come ❤ that itself deserves a Nobel Prize
Facts!
far*
I love how Issac Newton pokes out but stays in the shadows
Despite what he claimed, he really was a giant of science.
I didn't know that about the James Webb Telescope. Thanks for letting us know in your easy way of explaining it to us. It's much appreciated.
5:30 I feel like you didn't really explain why these light sources are infrared. You're talking about age of the light. Not the Doppler shift that is occuring due to these objects moving away from us rapidly
It's the expansion of the universe that causes the light to stretch into the infrared.
EXCELLENT explanation of JWST.
Great video, connecting Webb with the past. Well done 👏👏👏
Admin forgot intro😂
And I liked it!
Amazing Video! I hope RUclips shows it to lots of people, I'd love to see another video for all of the amazing images the James Webb created
Great. Video. Really learned a lot.
The immense pride for humanity’s inquisitiveness and ability to pull out such feats after watching such videos🥺
A truly awesome creation!
What awesome video!!! Keep up the great work man!
Waiting for that "whole another video" covering the JWST work from day zero in space until now.
9:00 The amount of gold by volume is 2.5 cubic centimeter, 2.5 ml, or 1/2 teaspoon.
Speaking of time machines, I ponder this: if FTL communication is actually possible, and say we make contact with a advanced civilization some 10,000 light years away, would it be possible for them to aim an ungodly powerful telescope at Earth, and see Earth as it was ten millennia ago? They could then send digitized copies of these photos via FTL, and we would have perhaps clear sharp photos of the Earth from back then? Pretty crazy, right?
Thanks to the amazing fiability of Ariane 5 launcher, the telescope just won a few years of life
I wish there was a dedicated space telescope that specifically looks at/searches within our stellar neighborhood. Deeply searches stars/exoplanets within 10ly, currently 30 solar systems... then 20ly , currently 117 solar systems.
Great content! Thank you!
I was so inspired by our SHuttle program, I was hurt emotionally with the Challenger incident, I was sad when i was reading how the Hubble was being delayed because of the Challenger. I was so excited when we were able to restart the Shuttle program. I became so sad again with the Columbia incident. then excited when we returned again, then sad when we retired the program. became so excited with the Webb telescope launch, and have such great feelings today about our program with NASA and also Elon's SpaceX. one thing I am confused by, with a telescope, if you can see far enough, like say to Pluto, you see pluto just slightly faster then the light reaching us naturally.. so in a sense, naturally we are seeing the past, but a telescope brings us to a closer present time. how is it everyone says we are seeing the past with James Webb telescope, and not a more closer representation of the present? if the light we see today is passing us by, from what ever amount of light years away an object is, then how do we see something that already past us by using the Webb telescope?
Hey, remember all the people in your comments that were constantly begging SpaceX to come save the Starliner crew (even though it isn't necessary)?
Why all the crickets, all of a sudden?
Did something happen to the Falcon 9?
Great stuff!
Wonder if we could use the gateway station to get to JWS if needed?
It's also runs on a space rated IBM PowerPC G3.
Another awesome and informative video. Additionally, the audio was much better, with only a few moments of sounding overprocessed (and not at all like an AI reproduction of your voice. Nor like the alternative narrator, who is preferred to the AI-sounding one.)
12:08 There is no such thing as "degrees Kelvin" as Kelvin is dimensionless, so it's simply "Kelvin".
Hubble 2 can't wait.
So cool…. Thx👍
11:24 The graphic says -223C, but you said -233C. Which temperature is the cold side?
98th!!!! YESSSSS!!!
17:20 SpaceX fandom and all aside, what is starship supposed to do with Webb? Its not build to be serviced
12:05 It's not "which is just seven degrees Kelvin."
It's just seven kelvin (7 K), not seven degrees kelvin (7 ºK).
Degrees Kelvin (°K) has not been used for over 55 years.
Make video on HWO: revamp version of jems web telescope
infinitely more watchable with the original narrator.
The big bang theory explains why light cannot go on forever.
We create telescopes to see the light of things that are very far away. We create microscopes to see the light of things that are very small. That which we observe , particularly with microscopes, has no idea we and our world even exist. It is too large for their senses to comprehend. What makes us think 'something' incredibly large is not observing us? And more to the point, can we create something to see the light from something inestimably larger than ourselves? And what if our space is their microscopic world? Just pondering stuff....
You really do not understand how big the observable universe is, do you? We can see 93 billion lights years wide. Aint nothing like that out there.
Don't be condescending. You obviously don't understand the question. @@filonin2
cool
I wished we made multiple ones and launched them in rapid succession. It could save cost in the end like how Spirit and Opportunity was.
Economy of scale doesn´t apply to 2 pieces
First! Miss ya Itsyeboi!
first what???
Which means it’s 15 years behind a high school science teacher average class being taught!!!!
Firsty first!
I'm. The First here
All the tons are metric.
Hartstikke leuk maar dit gaat in tegen het Europees recht dat iedere Europeaan heeft om te wonen en leven binnen Europa
Degrees kelvin is not such a thing

Cheese
James Webb was a guy who actively reported gay colleages to the fascists - not a person who deserves having a miracle of science named after him.
NASA did an investigation of that and made a report about it. If you have any evidence that they don't have, feel free to share it with them.
Galileo DIDN'T invent the telescope. Some unfortunately anonymous Netherlander did.
Galileo read about the invention. Over the 1609-1610 winter, Galileo built his own. Galileo was the FIRST to study the heavens with the telescope, reporting revolutionary discoveries in 1610.
(A possibility exists that the telescope predates 1609. If so, it was a classified top-secret high-tech military instrument.)
Check your facts first - Galileo did not invent the telescope ...
Let Elon Musk do the next one. It will be better and cheaper.
Something is wrong with your Video, it's very grainy and has many video artefacts.
Auto tune or AI generated voice over? Either way sounds pretty shite.
Real engineering does it better 😅
Woh! £150m for one instrument! That's crazy!
*My country gives £3b to Ukraine for a war they can't win...
Can someone explain to me why we should spend 10 billion dollars on JWST? Seems like a waste and that money should have gone to something more useful. What does JWST actually do for us?
If you think understanding how the universe works and came to be is a waste of money then boy are you not going to like the military budget that spends that much money every 4 days, always. $874 billion/year. JWST was paid for over a very long time as well.
@@filonin2 right I know what it can teach us. But the bottom line is that it doesn’t do anything for us. Cool we get to see some phenomenon but it’s not exactly going to power our cities. Or cure any illnesses, or advance any technologies. My point is simple, I think the 10 billion could have been spent elsewhere like fusion or fission reactor research. Or nuclear thermal propulsion. Just better uses of the money could have been found. And the universe was made by god btw.
#1. The money isn't spent "out there" in space. It's spent here on Earth. And the cost is spread over the lifetime of the mission - about 20+ years or longer if nothing critical breaks.
#2. This is fundamental research that gives us knowledge about the nature of the universe. It's for the same reason the Large Hadron Collider - which studies the subatomic realm - was built. Part of "How did we get here?", "Is there anybody else out there?", "How will it all end?" questions humans have been asking for millennia.
...And, of course, there is education, prestige (all nations love to brag about having the best [blank] in the world), technology development, etc.
Will discoveries made using the JWST make your life any easier? I doubt it. When Galileo built his own "spyglass" for the Italian Navy (yeah... They had military funding back in the 17th century), it didn't change the quality of life for the average person. It 'only' forced us to change the way we perceive all of creation and our place in it.
