Hey Fraser… With regard to Starship development, I have a significant worry to do with potentially inadequate protection from the exhaust plume that the 33(?) powerful Raptor engines are set to produce. Firstly, the launch tower is built so close to the storage tanks that fuel the rocket. secondly, after having seen the Artemis rocket plume that was produced with directional channels constructed underneath, in contrast to the lack of any such precautions constructed around the Starship launch tower, I’m not sure where all the exhaust is supposed to go! Thirdly (and perhaps most worryingly as this is a real unknown), if and when the Starship moon lander actually makes it there, I’ve not heard of any reassurance that the engines will be adequately protected from the loose moon regolith that will be kicked up by the rocket plume. Do you share this worry? What are your thoughts?
Absofreakinglutely! And Neil DeGrasse Tyson says that to end his show on here, now, too. It makes me nostalgic every time I hear it - I often think of Horkenheimer, since he was such a part of my younger days. I just love hearing the phrase still in use!
Wow, that Video of the Launch was awesome. In retrospect placing a Camera there was a no brainer as we see it all the time in Model Rocketry but that might be the first time I ever seen one like that. I have seen "first person" perspectives of the secondary stage and what not but never something like this at launch. It just hits differently watching it from that angle, thanks for that.

Hello Fraser! I've been trying to find everywhere for years a modification of the 'quantum eraser delayed choice experiment' that i call "The opposite way experiment".. Originally, the photons hitting the screen will behave as: - If we measure after the/any delay, the screen will display 2 solid lines. - If we don't measure after the delay(or can't acquire knowledge on which slit it passed through), there we get an interference pattern My suggestion is that we introduce a delay into the process, big enough that we can see the result on the screen, and act on changing the setup. - If the screen displays an interference pattern, we will leave the sensors open to 'see the result'. - If the screen displayed 2 solid lines, we will close the sensors. The idea for the delay is that after a photon/electon has passed the slit and we split it with a prism, the one entagled part hits the screen and the other will hit our sensors, but we will send the stream first to a mirror on the moon(i've also heard they used the mirrors to calculate the distance), which would would be ~2.6 seconds (roughly 1.3 lightseconds away *2 for the round-trip). Essentially, we introduce a 2.5 sec window(or find a way to have a bigger delay), in which time we see the pattern on the screen. I assume this specific setup has some flaws and would like to see why it could not work, as it "suggests a paradox"(and we all know that paradoxes means that some of our assumptions is wrong.. the universe does not have glitches)
I get this too. I think its a kind of mania. You have to set up the experiment yourself or move on. If you do the experiment, make a TH-cam video about it.
I live in eastern Canada and my daughter seen an asteroid burning up in the sky on her way home the night of Nov 19. Pretty cool … she said it was bright and had a long tail
First-time viewer, but you have great presentation, so +1 sub. Looking forward to more topical content (I think YT brought me here for the asteroid exploding over Canada story).
Incredible launch and there will be a lot more update on the damage it did to the pad. NASA is trying really hard to keep it under wraps but there's so much footage out there already. That tower was built a wicked long time ago costing billions and now they gotta fix it.. gonna be a while to do that and I'm really interested in how they'll manage that.
That is one weird journey that Artemis will have taken once it returns to Earth! I haven't been following things really closely, and thought it was just going to spend a few days in a "normal" orbit of the moon before coming back. . .
re - 17:00 What do you mean when you say the ELA will be able to "image earth size worlds around sun size stars?" More precisely, what do you mean by "image?" Might we expect it to be the kind of image we just saw of Titan? Or by "image," do you mean that it will take spectrographic readings of planetary atmospheres? What kind of image can we expect to see?
It'll be able to take direct images of exoplanets. It won't be like that Titan pic, it'll be a single pixel. From that they'll be able to detect atmospheres, etc.
At the end of the day the light show was six years late, cost $23,000,000,000.00 and disposable. That means each and every light show will cost $4,500,000,000.00 plus the cost of repairs of any damage caused during the light show.
I can remember in the late 1990s NASA said a small asteroid is about to enter the Earth’s atmosphere and land in the Indian Ocean, and it did. That was the FIRST TIME NASA did that.
This major suggestion for all your future videos. There is still some people out there that when they went to school the metric system Was not being taught yet. We're still part of the Fahrenheit, Inches and feet generation. It would help not only for the understanding portion of your videos but the enjoyment of them if you could please give us the Information with metric as well as the old school of Fahrenheit and feet. Thank you I look forward to seeing more videos.
@Revolvermaster RE: "Pretty impressive that a 1 M object was detected ahead of time!" If a one-meter-sized object was detected three hours before it exploded in the atmosphere, I wonder at what distance that a dinosaur-killer asteroid (10,000 meters) could be detected. I was disappointed that the narrator did not do that extrapolation.
Last year l was driving down an open road. No traffic, no trees, no wind & something from somewhere hit my windshield, causing a pretty substantial Crack. The only thing I think it could have been is a micro meteor. There was no other explanation.
If you are about to run out of stuff to cover Fraser, to address two issues in more detail, adaptive optic system and making pictures with the help of gravity lenses, would be really interesting, I understand the principle, but have difficulty in understand how light/photons are so predictable that scientists can reconstruct rays of light that are mixed together by air or gravity, just a suggestion
@@scott6129- yes, exactly, but how? This is what I do not understand, how do they know where the different photons are supposed to be? What they receive are distorted light from the source, how to reconstruct it?
About 7 years ago i was outside at 3 am, star gazing as per usual, and coming in at a 45° angle, I saw what looked like a flaming nurf football slowly coming down my street... It looked like it was in slow motion, pressing against the atmosphere...it traveled the entire distance of my street, passed my house, and 2 doors down I exploded 4 feet above the ground, making a very loud noise that woke many of my neighbors. I had been looking towards Venus, in the direction of where the sun would rise in the next 2 hrs when I saw the flaming rock fall out of the sky... Didn't even make the news... I looked for fragments but found nothing
4:31 you say early warning system and then you say 3.5 hours is that early ? Can you launch anything in that time, only launch not have time to intercept it ? What if weather conditions are "not right" ? How much time do we need to asses and calculate size and speed of "the impactor"? How much time do we need to build it? ........?
@@frasercain ok, say we have 1 month, now imagine that one larger object which we can detect whole month before collision is coming to us, also imagine that we need impactor of say 1000 kilograms to divert that object from collision course, tell us in this scenario what is the time needed to construct and launch tis impactor and what is the last moment we can hit this object to divert it ? Yes there is lots of imagination here, but also we could go into details if you want, we can calculate the size and mass of object which we can detect month in advance and then calculate precise speed and mass of the impactor needed and construction and launch time and all kinds of stuff but I suspect it would be even worse case than given imaginary example, so let us hope this is the scenario and give us estimation can it be done in this case ? If not than it would be even harder in real case and with even larger objects, if we can do this imaginary scenario in time than we have some hope to do it for real object which will come one day or another. I am not pessimistic, and I do want us to be ready for that day, but this is not even close to what is needed to do such thing when we do detect the objects of that size about which we should worry. One potential solution would be to have something half ready in orbit or on the moon to save some time and have enough fuel to even try to divert the objects of size which we should worry about, and even then what if there is 2 objects, what if we misjudge the size or speed or mass of the object, what if one impactor fails, what if we miss it and now both impactor and the object are coming to us..... it would not be the first time we missed something or did not calculate something correctly or just had bad luck and not done as planned, what then ? What is the backup plan ? If life on the Earth is in question we should have backup of the backup and even more backup plans but we are not sure even if our main plan would work. Again sorry for bad news and dark thoughts but it is reality if it can happen it will, remember ?
It is my limited understanding of space that everything out there is constantly moving. My question is. Does what we see today of something light years away mean that it is no longer in that location?
If an asteroid like the Chelyabinsk one burst over a major city like Toronto I can only imagine the devastation. I mean it's not going to kill anyone directly, but I'd imagine there'd be an awful lot of broken glass etc. and shards falling off a downtown skyscraper's plate glass windows could cause a lot of injuries. Cool they can now potentially give everyone a few hours notice to get out the way.
@1dgram RE: "A 3-day warning of impact is not enough yet. It took months for the Artemis rocket to take off after it was first brought out to the pad." An anti-asteroid launch system would not be as complex or cumbersome as the SLS. The correct model would be a worldwide network of anti-asteroid guided missiles, similar to antiaircraft and antimissile defense systems, but with much greater delta-v.
Watching the launch at the beginning of this video, I was wondering if fuel might be saved by imparting just a little bit of momentum to the rocket (aircraft carrier luanch style).
It weighs about 2500 metric tons at launch. An F35 about 13. Probably very unfeasible. But there's a plan to basically slingshot a much smaller rocket.
Does NASA or anyone else have an APP to track asteroid impacts and tell the public about them. It would have been great to watch this latest asteroid land in southern Ontario. Can anyone provide any insight or ideas?
Fraser -- Apologies if I misheard what you said at about 17 min 48 sec, but it's Johns Hopkins University -- please make sure we can hear the "s" at the end of both words in the name.
Crazy accurate because I came home from work at 3am was smoking my vape went to go inside then watched the asteroid hit the atmosphere and burn up super cool I've never seen a proper asteroid in my life you could see the huge flame trail and everything pretty cool
I am a long time subscriber and really enjoy the information you give to us.. but I have a serious question regarding the layers of the galaxies and their distance... With the ever expansion of the universe, how is it that the closest galaxies are spiral, then to have all of the farther elliptical galaxies described as galaxies that have collided
Because you can see all the distant spirals any more. They're not bright enough. If you look at a city from a few km away, you can't see all the candles. They're there, they're just not bright enough.
Artemis was SO BRIGHT that many of our cameras just could not focus... I know my Nikon and my telescope camera both just went into ' bright ball ' mode Next time, I'll make sure I have a set of stacked lens filters to reduce that much glare, especially on my telescope camera I use to record video onto my laptop.
I try to go to most of them and if not, at least go out in my back yard. I could see the glow a good minute-minute and a half before the ' live ' show on TH-cam showed the launch and felt the ground shaking all the way down in Palm Bay, Florida before I could see the light from the Artemis engines over the trees... both cameras were just showing a ball of bright light... even my cell phone. I've been playing with a small telescope and have my laptop connected to it with a nice smooth ball joint on the tripod... one of these days, I'll get it right and be in the right place at the right time. You have a GREAT SHOW !
It was only 3 hours because it was so freaking tiny! We're getting really great at finding the biggest ones, pretty good at finding the medium sized ones, and fairly decent at finding the ones that are small enough to cause significant damage. This one was miniscule, though, and the fact that they found it at all, at that size, is incredibly impressive!
Why would you want three years to worry about how bad the devastation was going to be. One hour would be to long to wait for a planet killer asteroid to collide with the earth!
For asteroid impacts can we predict the exact angle and height in the atmosphere it'll explode? I've thought about what would've happened if the Chelyabinsk event had been seen days or weeks before impact. It would've been this huge event the entire world remembered. For the city I think it would've led to mass panic and probably more injuries than actually occurred. Yes in hindsight we know it was just minor damage but really think about it, this thing packed the punch of good sized nuclear weapon. So now imagine this being announced weeks ahead of time and not knowing exactly where it would strike, the whole world waiting to hear the random place a nuke sized explosion more than capable of wiping out a city would hit. Then as it narrows to Russia and then Chelyabinsk telling the people there "hey this thing is going explode off over (or maybe in) your city" is going to lead to immediate chaos and panic as people try to flee the city. Even if we knew that it's angle would led to an air burst too high to do much more than blow out windows, I still think people wouldn't want to risk it and would've fled the city.
That map is amazing but I’m a bit confused, doesn’t take much. If spiral galaxies become elliptical galaxies, why aren’t they the nearest and youngest objects on the map? Thanks Fraser.
I've always wondered why, as the ship (or whatever it is) is about to go around the moon why on the way to the moon it doesn't drop a little satellite and kick it back behind it so that as it's on the dark side of the moon it can relay the signal back to Earth while it's out of comms.. Wouldn't that like NOT cost a lot of money and be a really SUPER GREAT idea??
I don't expect NASA to do the same sort of marketing /PR video feeds SpaceX does. The Engineers get what they need/want and I realize they're not doing it for my entertainment.
It appears to be pretty well debunked at this point. Here's a recent science paper that refutes the evidence: www.sciencedirect.com/science/article/abs/pii/S0012825211000262
All the images are in the pipeline, then given to scientists, and they'll only be published after months of analysis? And in this pipeline there's no space for a single lousy image to be shown to the general public? Well, that really makes sense. As much sense as Artemis being incapable of sending one image of Earth in which the Earth is big enough to be identified as Earth beyond doubt. Someone commented under that clip that it's really problematic to send high resolution images from space LOL. Sure, sending one image is a problem, but streaming 4K video is not a problem at all:) And I wonder what kind of camera is installed on the Artemis? Because by the quality of the streamed images, it's probably some kind of USB webcam. I was even so optimistic that I expected they would slap some moderately priced zoom lens on the camera, but of course webcams don't have that option... On the other hand, that image of Titan is awesome! OK, it had to be upscaled, probably to save bandwidth, and the choice of colors are really a matter of artist's preference, but what's really important is that it looks very round, so much so that it almost looks unnatural. You're absolutely right about one thing, though - we haven't seen anything yet...
I've been showing off several new images from JWST every week. This might be the first of my videos you've seen. Want almost live images of Earth, check out the feed from DSCOVR: epic.gsfc.nasa.gov/
hi Fraser! great episode, fist time i saw that Artemis launch booster video. I have a question though: are you aware of any planetarium apps that can show the stars/constellations (edit: or the entire night sky, for that matter) as they are now? as if there was no light delay and we saw everything in their current actual positions?
I live 10 miles from Kennedy and I’ve never seen something so spectacular launch. It was like the sun rising. I thought at first it blew up cuz the ball of fire was massive
Not sure if, but im thinking this is what hit over Grimsby Ont . people are on the escarpment searching for pieces. Are we sure that everything burned up? wouldnt want to waste my time walking my dog... while time spent with the dog is never a waste, it would be cool to find more then cool sticks
Does anyone else think the moon looks fake in these videos…? Particularly the shot from the Orion capsule.. great channel though and I’m glad I subbed!
It's just low quality. It's hard to compete with the much better cameras and telescopes that watch the Moon. But I'm sure we'll see much better images once Orion returns and the terabytes of data get processed.
Still hoping to see that 100 meter diameter OWL telescope some day 🙂 They are European Southern Observatory (ESO) telescopes so they are named by committee rather than by who donated the most money to build them like for example the Keck telescopes (Keck Foundation, founded by an oil executive).
The has been some news that people are pushing for a bigger version of JWST that see's in the same frequencies as Hubble. They want to call it The Carl Sagan Observatory. If it gets built it will have a 12 meter set of mirrors. Dr Becky's channel th-cam.com/video/BIgQpXObjFI/w-d-xo.html
It’s sad that a dude can smash up perfectly good trucks for millions of subs and views, yet FC and his extremely informative space channel it’s only at 350 subs ( not to snooze at) but we all know who’s deserving of way more .
@@frasercain 😂all fun aside. I’ve been absolutely fascinated with all things space since the age of about 12. Guys like yourself make layman’s like me understand the more technical points of all things associated with it. Thanks for your hard work giving us these awesome vids. PS. I still can’t get my tiny chimp brain fully around gravitational lensing, which intrigues me probably the most out of all things .

RE: "Pretty impressive that a 1 M object was detected ahead of time!"
If a one-meter-sized object was detected three hours before it exploded in the atmosphere, I wonder at what distance that a dinosaur-killer asteroid (10,000 meters) could be detected. I was disappointed that the narrator did not do that extrapolation.
Hi from Wales 🏴. Just discovered your channel by chance. It is a pleasure to subscribe you and I’ve hit that bell too 🔔.
Last year l was driving down an open road. No traffic, no trees, no wind & something from somewhere hit my windshield, causing a pretty substantial Crack. The only thing I think it could have been is a micro meteor. There was no other explanation.
If you are about to run out of stuff to cover Fraser, to address two issues in more detail, adaptive optic system and making pictures with the help of gravity lenses, would be really interesting, I understand the principle, but have difficulty in understand how light/photons are so predictable that scientists can reconstruct rays of light that are mixed together by air or gravity, just a suggestion
@@scott6129- yes, exactly, but how? This is what I do not understand, how do they know where the different photons are supposed to be? What they receive are distorted light from the source, how to reconstruct it?
@@scott6129 - work on a Saturday?
When will james webb will see Uranus
I live in the Hamilton Ontario Canada area. and i felt it at 3:30am and it was loud.
About 7 years ago i was outside at 3 am, star gazing as per usual, and coming in at a 45° angle, I saw what looked like a flaming nurf football slowly coming down my street...
It looked like it was in slow motion, pressing against the atmosphere...it traveled the entire distance of my street, passed my house, and 2 doors down I exploded 4 feet above the ground, making a very loud noise that woke many of my neighbors.
I had been looking towards Venus, in the direction of where the sun would rise in the next 2 hrs when I saw the flaming rock fall out of the sky...
Didn't even make the news...
I looked for fragments but found nothing
I live in Southern Ontario ... all the Tim Horton's locations are operational.
May the coffee be with you.
Well, that's what's important.
how big can we make an impactor with current tech? and what yield would it have? still want them to use Casaba howitzer though
4:31 you say early warning system and then you say 3.5 hours is that early ? Can you launch anything in that time, only launch not have time to intercept it ? What if weather conditions are "not right" ? How much time do we need to asses and calculate size and speed of "the impactor"? How much time do we need to build it? ........?
You'd get days or even weeks notice for a larger object.
@@frasercain ok, say we have 1 month, now imagine that one larger object which we can detect whole month before collision is coming to us, also imagine that we need impactor of say 1000 kilograms to divert that object from collision course, tell us in this scenario what is the time needed to construct and launch tis impactor and what is the last moment we can hit this object to divert it ?
Yes there is lots of imagination here, but also we could go into details if you want, we can calculate the size and mass of object which we can detect month in advance and then calculate precise speed and mass of the impactor needed and construction and launch time and all kinds of stuff but I suspect it would be even worse case than given imaginary example, so let us hope this is the scenario and give us estimation can it be done in this case ? If not than it would be even harder in real case and with even larger objects, if we can do this imaginary scenario in time than we have some hope to do it for real object which will come one day or another. I am not pessimistic, and I do want us to be ready for that day, but this is not even close to what is needed to do such thing when we do detect the objects of that size about which we should worry. One potential solution would be to have something half ready in orbit or on the moon to save some time and have enough fuel to even try to divert the objects of size which we should worry about, and even then what if there is 2 objects, what if we misjudge the size or speed or mass of the object, what if one impactor fails, what if we miss it and now both impactor and the object are coming to us..... it would not be the first time we missed something or did not calculate something correctly or just had bad luck and not done as planned, what then ? What is the backup plan ? If life on the Earth is in question we should have backup of the backup and even more backup plans but we are not sure even if our main plan would work. Again sorry for bad news and dark thoughts but it is reality if it can happen it will, remember ?
Sorry for the Artemis issue. I parked my spaceship in the way by accident. 😬
Thanks for the news, Fraser!
Stay safe there with your family! 🖖😊
It is my limited understanding of space that everything out there is constantly moving.
My question is. Does what we see today of something light years away mean that it is no longer in that location?
Would 2 Vera Rubins (1 each in the southern and northern hemispheres) make us asteroid proof?
Could they not have provided an energy light source for the CubeSat units?
Great work mate!
If an asteroid like the Chelyabinsk one burst over a major city like Toronto I can only imagine the devastation. I mean it's not going to kill anyone directly, but I'd imagine there'd be an awful lot of broken glass etc. and shards falling off a downtown skyscraper's plate glass windows could cause a lot of injuries. Cool they can now potentially give everyone a few hours notice to get out the way.
What was the name of the website of the universe map??
A 3 day warning of impact is not enough yet. It took months for the Artemis rocket to take off after it was first brought out to the pad.
@1dgram
RE: "A 3-day warning of impact is not enough yet. It took months for the Artemis rocket to take off after it was first brought out to the pad."
An anti-asteroid launch system would not be as complex or cumbersome as the SLS. The correct model would be a worldwide network of anti-asteroid guided missiles, similar to antiaircraft and antimissile defense systems, but with much greater delta-v.
@@spaceman081447 The earlier an asteroid can be impacted, the further it can be deflected.
Watching the launch at the beginning of this video, I was wondering if fuel might be saved by imparting just a little bit of momentum to the rocket (aircraft carrier luanch style).
It weighs about 2500 metric tons at launch. An F35 about 13. Probably very unfeasible. But there's a plan to basically slingshot a much smaller rocket.
Does NASA or anyone else have an APP to track asteroid impacts and tell the public about them. It would have been great to watch this latest asteroid land in southern Ontario. Can anyone provide any insight or ideas?
Just because twas a meter in diameter doesn't mean that it is certainly "harmless". Harmless at many velocities perhaps.
It does mean it is harmless as rocks that size burn up into small rocks and dust.
So shouldn't we be seeing spiral galaxies farther away and elliptical closer up? Farther away is approximately longer ago?
Fraser -- Apologies if I misheard what you said at about 17 min 48 sec, but it's Johns Hopkins University -- please make sure we can hear the "s" at the end of both words in the name.
Crazy accurate because I came home from work at 3am was smoking my vape went to go inside then watched the asteroid hit the atmosphere and burn up super cool I've never seen a proper asteroid in my life you could see the huge flame trail and everything pretty cool
Oh, I'm so jealous. That must have been amazing, but a little scary.
I am a long time subscriber and really enjoy the information you give to us.. but I have a serious question regarding the layers of the galaxies and their distance...
With the ever expansion of the universe, how is it that the closest galaxies are spiral, then to have all of the farther elliptical galaxies described as galaxies that have collided
Because you can see all the distant spirals any more. They're not bright enough. If you look at a city from a few km away, you can't see all the candles. They're there, they're just not bright enough.
I think i saw the asteroid! It was crazy cool to see it break apart and move so slow in the sky
I've been out looking for it, it landed in my area where I live. If I find anything I will be sure to let you know. Lots of folks out there looking !
Hah, good luck!
Couple of years ago saw a fire ball over Toronto, headed west. Anyone else see it?
Artemis was SO BRIGHT that many of our cameras just could not focus... I know my Nikon and my telescope camera both just went into ' bright ball ' mode Next time, I'll make sure I have a set of stacked lens filters to reduce that much glare, especially on my telescope camera I use to record video onto my laptop.
Oh wow, that's really interesting. You don't realize just how bright it's going to be and how difficult to account for it.
I try to go to most of them and if not, at least go out in my back yard. I could see the glow a good minute-minute and a half before the ' live ' show on TH-cam showed the launch and felt the ground shaking all the way down in Palm Bay, Florida before I could see the light from the Artemis engines over the trees... both cameras were just showing a ball of bright light... even my cell phone. I've been playing with a small telescope and have my laptop connected to it with a nice smooth ball joint on the tripod... one of these days, I'll get it right and be in the right place at the right time.
You have a GREAT SHOW !
On the lack of live SLS launch video, what do expect for $23 billion dollars?
Honestly we need a 3-year warning if the rock is big enough to be truly threatening.
Three hours is definitely the last minute....
It was only 3 hours because it was so freaking tiny! We're getting really great at finding the biggest ones, pretty good at finding the medium sized ones, and fairly decent at finding the ones that are small enough to cause significant damage. This one was miniscule, though, and the fact that they found it at all, at that size, is incredibly impressive!
3 years? So society can get a head start on completely destroying the planet before the asteroid does?
@@MaryAnnNytowl Thanks!!
Why would you want three years to worry about how bad the devastation was going to be.
One hour would be to long to wait for a planet killer asteroid to collide with the earth!
Will 3 hours notice be sufficient to do anything?
Get away from windows so you don't get hit by shattering glass like what happened with Chelyabinsk.
How do I get the new Johns Hopkins map?
My question is, Why can't they slow down the Orin Capsel before it hits the ATM of earth. They had to build a new heat shield.
Who are these people actually disappointed with the James Webb? I want names.
For asteroid impacts can we predict the exact angle and height in the atmosphere it'll explode? I've thought about what would've happened if the Chelyabinsk event had been seen days or weeks before impact. It would've been this huge event the entire world remembered. For the city I think it would've led to mass panic and probably more injuries than actually occurred. Yes in hindsight we know it was just minor damage but really think about it, this thing packed the punch of good sized nuclear weapon.
So now imagine this being announced weeks ahead of time and not knowing exactly where it would strike, the whole world waiting to hear the random place a nuke sized explosion more than capable of wiping out a city would hit. Then as it narrows to Russia and then Chelyabinsk telling the people there "hey this thing is going explode off over (or maybe in) your city" is going to lead to immediate chaos and panic as people try to flee the city. Even if we knew that it's angle would led to an air burst too high to do much more than blow out windows, I still think people wouldn't want to risk it and would've fled the city.
I wasn't aware of anybody being disappointed with the James Webb
You should read my comments.
I'm glad the graphic at 3:44 is fictional---
We're in Eugene, Oregon and it's heading right for us! 😜
That map is amazing but I’m a bit confused, doesn’t take much. If spiral galaxies become elliptical galaxies, why aren’t they the nearest and youngest objects on the map? Thanks Fraser.
Because we can't see the spiral galaxies that are more than a few billion light years away. They're there, just dim so we can't see them.
Has Webb looked at Betelgeuse yet?
I've always wondered why, as the ship (or whatever it is) is about to go around the moon why on the way to the moon it doesn't drop a little satellite and kick it back behind it so that as it's on the dark side of the moon it can relay the signal back to Earth while it's out of comms.. Wouldn't that like NOT cost a lot of money and be a really SUPER GREAT idea??
I don't expect NASA to do the same sort of marketing /PR video feeds SpaceX does. The Engineers get what they need/want and I realize they're not doing it for my entertainment.
Oh, it’s pure entertainment.
@@Withoutmixture wow! What do you mean?
Hey Fraser! Could a shadow "travel" faster than light?
No. Shadows travel at the speed of light because they are the inverse of light.
So, about that map of the Lagrange points in the Universe at the dawn of time... LOL 😀, thanks for the update.
What is your take on the Younger Dryas impact theory?
It appears to be pretty well debunked at this point. Here's a recent science paper that refutes the evidence: www.sciencedirect.com/science/article/abs/pii/S0012825211000262
@@frasercain thanks for the info I will check it out
All the images are in the pipeline, then given to scientists, and they'll only be published after months of analysis? And in this pipeline there's no space for a single lousy image to be shown to the general public? Well, that really makes sense. As much sense as Artemis being incapable of sending one image of Earth in which the Earth is big enough to be identified as Earth beyond doubt. Someone commented under that clip that it's really problematic to send high resolution images from space LOL. Sure, sending one image is a problem, but streaming 4K video is not a problem at all:) And I wonder what kind of camera is installed on the Artemis? Because by the quality of the streamed images, it's probably some kind of USB webcam. I was even so optimistic that I expected they would slap some moderately priced zoom lens on the camera, but of course webcams don't have that option...
On the other hand, that image of Titan is awesome! OK, it had to be upscaled, probably to save bandwidth, and the choice of colors are really a matter of artist's preference, but what's really important is that it looks very round, so much so that it almost looks unnatural.
You're absolutely right about one thing, though - we haven't seen anything yet...
I've been showing off several new images from JWST every week. This might be the first of my videos you've seen. Want almost live images of Earth, check out the feed from DSCOVR: epic.gsfc.nasa.gov/

hi Fraser! great episode, fist time i saw that Artemis launch booster video.
I have a question though: are you aware of any planetarium apps that can show the stars/constellations (edit: or the entire night sky, for that matter) as they are now? as if there was no light delay and we saw everything in their current actual positions?
I live 10 miles from Kennedy and I’ve never seen something so spectacular launch. It was like the sun rising. I thought at first it blew up cuz the ball of fire was massive
I'm jealous. :-)
So...
What's the deal with the astroid hitting Norway?
Not sure if, but im thinking this is what hit over Grimsby Ont . people are on the escarpment searching for pieces. Are we sure that everything burned up? wouldnt want to waste my time walking my dog... while time spent with the dog is never a waste, it would be cool to find more then cool sticks
Ask about Star / Galaxy formation. Does it use the boiling point of Hydrogen or Lithium (1% after big bang)?
I saw this while driving home the other week.
Wow, that must have been intense.
Does anyone else think the moon looks fake in these videos…? Particularly the shot from the Orion capsule..
great channel though and I’m glad I subbed!
It's just low quality. It's hard to compete with the much better cameras and telescopes that watch the Moon. But I'm sure we'll see much better images once Orion returns and the terabytes of data get processed.
Are you aware of any DARPA missions to possibly use Rail Gun Tech. to deflect asteroids ?
Hey great reporting 👍
Sooo is the next telescope after the extremely large telescope going to be called the unbelievably large telescope? Eventually we’ll run out of terms!
It was going to be called the "Overwhelmingly Large Telescope." There's an XKCD comic for you: xkcd.com/1294/
Still hoping to see that 100 meter diameter OWL telescope some day 🙂 They are European Southern Observatory (ESO) telescopes so they are named by committee rather than by who donated the most money to build them like for example the Keck telescopes (Keck Foundation, founded by an oil executive).
The has been some news that people are pushing for a bigger version of JWST that see's in the same frequencies as Hubble. They want to call it The Carl Sagan Observatory. If it gets built it will have a 12 meter set of mirrors. Dr Becky's channel th-cam.com/video/BIgQpXObjFI/w-d-xo.html
