I am a little sad at how far the Hubble has fallen in reference to JWST. I know JWST is awesome but Hubble will always be the telescope that opened space to the public.
I don’t see it as a competitive thing. Of course Hubble has been awesome - the excitement is all about the possibilities opened by the technological advancements during the period between Hubble and JWST. Comparisons with Hubble are simply a way of providing frames of reference for that excitement. We are all on the same team!

I read the Commissioning Report (even though it's way over my head, it's not my area of expertise), and it was really interesting.

Persistence of Memory is based in part on Einstein's theories of the relative nature of time. That you'd end up getting weird things like that. Gravitational lensing is also predicted by Einstein's theory and the lensing around the sun was one of the first clear observational proofs. So it's sort of full circle there...
I would like her to address this concern, if it is one. I don't fear clickbait when the good Dr. informs us. Other internet folk don't have her extensive credentials, her nimble span of complex knowledge, her infectious enthusiasm, the power in the rigor of her work. She be good!
Is there a way in which we might put Hubble & JWST images together into one composite image? Or would it be too hard to add the false colours for it to make sense to our eyes?
Your meme reaction videos always make me think of how my husband tells me jokes and I laugh and then try to add some sort of commentary (I'm a sociologist) and he responds (not wanting to really discuss serious stuff), "Thanks for telling me why my joke was not funny, Dr. Academic!" In my brain, I have nicknamed your meme reaction videos the "Dr. Academic" videos, but unlike my jokester husband, I enjoy the humor and the explanations!
I watched the JWST reveal on both NASA and your chammel. I had never seen a bonified nerd party before and was enjoying the feeds umtil I realized : Hey, I am watching too! Lov the channel thanks for all the effort.
Hypothetical question: Would you, from the data recorded by hubble, be able to identify other artificial objects in space. Like, let's say an alien species at a similar point in technological advancement decided that now would be a pretty good time to launch a space telescope (maybe similar to JWST or Hubble), could these see and identify each other? And how close would they need to be for that. And how about bigger objects like spaceships or entire space stations. Or an alien version of the voyager probes.
Something like the Voyager probes would be pretty much impossible to detect, they are way too small. Something far beyond JWST's capabilities would be necessary. A telescope is of a similar size. It's hard enough to detect planets, and they are much bigger than a probe. And we cannot even see planet 9 after all this time, and that's somewhere nearby, in our system and it should be bigger than Earth. Just think of the "pale blue dot" image.
The issue with that is the sheer vastness of space. The closest star to us is Proxima centauri, which is about 4,25 LY from us. So, even if some aliens from there watched us with something good enough to resolve JWST, they wouldn't see it for another 4 and 1/4 of years, because only then the first light reflected from the satelite would arrive there. So unless you're a close stellar neighbour, you won't really be able to see anything for decades / centuries. And if someone from further away ( let's say 100 LY away, which is, BTW, in space terms actually reeeeealy close, since the entire Milky way is at least 100 000 LY across) saw earth, they wouldn't see what we see. They would see a pre-spaceflight species (hell, probably pre-flight species). That's actually one of the solutions of Fermi's paradox - there are a lot of aliens around, but everyone is so far away from us, the light that left their planet while they are around didn't have enough time to reach us yet. Hell, the first civilisations on earth emerged probably no more than 10 000 years ago, so most of our own galaxy wouldn't see us for anything more than a smart animal even if they'd be able to see us at all. The other thing is the size of the artifical objects. We at our current technological level are at best able to observe planets (if we're talking about anything outside the sol system) and even that is possible only because the planets sometimes pass between us and their star. So no, someone with on our technological level wouldn't be able to find JWST, unless they were in our solar system, and since they would lack the means of interstellar travel, that would assume they evolved in our solar system alongside us. TL&DR I'm 99,99% sure someone on our technolgical level wouldn't be able to find any artifical object in our solar system, unless they were observing from within the solar system.
From NASA's JWST FAQ : "[Webb] will be able to see directly the reflected light of [Jupiter sized] planets." "It will also be possible to see very young planets in formation, while they are still hot." "Webb will not have the resolution to see any details on the planets." (Of course, this refers to planets outside our solar system.) So, JWST cannot see things as small and/or as cold as, say, the Earth. Things built by alien civilizations are right out -- even if they build something as big as the Death Star -- even if they build an artificial Earth! Only if an alien civilization were much, MUCH more advanced than us and built something the size of Jupiter (more than 10x the diameter of Earth and more than 1,000x the volume of Earth), or something as hot as a molten planet still undergoing formation, could JWST detect it. BUT, even if it could detect it, it could not see enough detail to distinguish it from an actual, natural planet.
@@D3emonic The true measure should be that of radio transmissions which we have only been broadcasting for 80 or so years. Thus no alien life form will be able to detect us until the 'bubble' has expanded into their sphere of influence and vice versa for us to detect them should they be capable of radio transmission/reception.
Dr. Becky tells you everything you need to know in this video to answer this question yourself. The Hubble doesn't have enough resolution to even be able to see Apollo spacecraft that landed on the moon 250,000 miles away as more than a single pixel. So, no, it isn't going to see another Hubble light years away. Spacecraft are TINY.
I did that Spider-man meme just after the images were revealed, except I did it correctly. He sees better without the glasses after being bitten by the spider, so that's where the JWST image should be.
Your new JWST merchandise is awesome. I ordered the JWST reflection t-shirt. I would have bought the JWST first science image t-shirt, but I think the lower right image should have been moved outward to make the images form a smiley face.
Are we about to reach a point in time when there are not enough people on this planet to study the data from billions of galaxies observed by JWST and future space telescopes?
I like these spontaneous looking up information. don't have to be very produced look and feels like you're just talking to us :). a neat trick to keep cool is to put a bucket of ice water in front of the fan. it'll keep you cool until you need to refreeze the ice again.
I always love when scientists covering really old or large timescales or objects say only because its always so crazy what they say next but somehow in the grandscheme of things it is only.
1:17 Glad to know I'm not the only astrophysicist who appreciates a great SpongeBob meme! Also appreciate the classic SpongeBob narration transitions throughout the video lol
So you turned the fan off for better audio and then had low battery issues on the mic. You have my every sympathy. Your dedication to your channel is admirable.
13:37 - question about the lensing stuff, and in particular where we get multiple images of the same object lensed in different ways: when we're building our "map" of things from that, is it also possible to sort of back-compute an un-distorted shape of what the object would look like, if not lensed?
Just what I was wondering when I saw some of the images on a video the other day. Also about how they can tell which are duplicate images of the same galaxy or if it's possible to get 2 images of a galaxy as it was at different times because the light takes longer to go the other way around the closer objects. Perhaps a time difference of thousands of years apart or hundreds of thousands (or millions) of years?
@@yahccs1 There is always a time difference when the light takes different routes. But when you have a candidate for a reconstruction, you will reconstruct a picture of the galaxy from each image independently, and try to make a progression fit for how the bright points in the galaxy ought to move. So: Possible, but also very processing heavy, plus it takes a hellalot "Say, could this one be a flipped and bent version of that one?" to even get started. Becky's not kidding when she says there will be PhDs earned by people not yet born, on the data Webb collects. :)
@@yahccs1 interesting question. I haven't done the math (nor do I even have the expertise to), but I suspect the difference in time would be _much much_ smaller than what you're talking about... seconds to maybe minutes, at most, I would think. Hmm, well, looking up Einstein radius or Schwarzschild radius could be informative. Indeed, on wiki's Schwarzschild_radius#Black_hole_classification_by_Schwarzschild_radius, one can see a radius of 400AU listed. That'd be 400*~8.3 =3320 light minutes, I guess? Or about 55 hours... which I'd say would be an estimate for the _maximum_ delta between the two arrival times. Could still be interesting in some contexts, maybe, but I think it'd fall short of what you're talking about, sadly.
dr becky please do an overlay review of the cloud at 1.42 . there are new stars in the JWST image and since the hubble photo the cloud has actually moved in areas as well . i like your approach to and knowledge of space and how easily you explain to the novice .
Telescope related. I’d be curious to have you talk about the observatory on La Palma since the volcano stopped erupting. When did it get back to routine operations?
Becky, are you planning on making a video addressing the recent damage the JWST has suffered due to the collision and how it may impact future researches?
I love that I found you recently (I don't remember how) after recently getting more into physics and that you also watch Kara and Nate 🤣 Edit: spelling
Cool explanation of the resolutions of each and their overlap. I rarely watch the bloopers but this time I did. Don't worry pretty lady, we're not here to watch or judge your hair 😉. Thanks for doing what you do and doing it so well. 😊
Another great video as always. Though there was a lot of white noise throughout the whole video for some reason. I tested my setup to make sure it wasn't me. Tried speakers, headphones, reloaded the video, played different video, etc. Only hearing it on this one.
Oh wow. I didn't realise that you filmed this on one the hottest days of the year and had to turn off your fan to do it. That's dedication. Thank goodness it's cooler now.
5:00 High-resolution horse head very exciting, but worth noting that if University of Arizona is behind the proposal it is surely related only to cheerleading
The only part that bugs me about the Spider-Man meme is that it's backwards. That's the part of the movie where he realizes he has super spider vision I guess, and that his glasses now make his vision blurry! I get why they used it for the meme just because of the imagery, but I can't help but think of how it looks from his end after having gone through spider puberty.
I am really looking forward to JWST looking at Orion. I have a 175MB image of it from Hubble but I can imagine how much more details JWST will reveal. I wonder if we will be able to work out what the cylinder shape is that was spotted in the image - photo artefact, real object, tinsel, etc.
When they state the observation times for images, is that the total time for all filters used, or the per filter time? That would kinda assume the exposure time for each filter is the same or nearly so, is that the case? The JWST 'deep field' used 6 filters, which would mean each filter was the 12+ hours or 2+ hours.
I don't know how optics work so why is it that we get pictures that aren't in the shape of a hexagon similar to the shape of the golden mirrors of Webb? And in the center there is no mirror so there's a hole so why do we get complete images without a hole in the middle?
@@marcuscarana9240 You seem spoiled, you want everything to be handed to you with no effort on your part. That isn't a good way to try to navigate through life! Take some responsibility and put your thinking in gear.
4:40 the one I personally am anticipating, bearing in mind looking at the same things again versus looking at entirely new things is kinda a big deal…but the one I’m looking forward to is the nebula/dust cloud dubbed “the pillars of creation”
Always great to have a fun video from you! One topic that might be worth a dive as I had no idea about it until I saw an article pop up in my feed. The concerns of micro-meteor strikes and how one of the mirrors already took a decent hit! BUT they were able to offset the mirror to null-out most of the impact's effects? Like.... how is that possible? If all the mirrors have to be focused at the same location to get clarity and resolution, how can you adjust the focus of one mirror to account for meteor impact damage? Then there's also the concern of if meteor strikes are going to be more common than originally simulated, thus potentially reducing the life-space of JWST?
You know, that is all good questions, it would be good to hear from someone who actually knows. But bear with me to share a frustration, especially on a site like this dealing with astronomy. The use of correct terms. A meteor is a flash of light as a meteoroid gets burned up entering the atmosphere. If part of it survives to the ground we call that a meteorite. So the gist of all this is a meteor cannot hit a Webb mirror. It was a meteoroid. Now your first reactions might be "why is this guy so nit-picking?" Well as I started out this is not some social club discussion, it is an astronomy and astrophysics channel so we owe it to each other to use correct terminology.
2:30 So would this be angular resolution of the optics and the sensing instrument ,detectors, together? Also Is this different for the spectrum detectors VS the image detectors?
It's based purely on the size of the mirror - the detectors and intermediate optics ultimately limit the resolution we see; some sensors even intentionally undersample the mirror because they value sensitivity over resolution...
Dr. Becky, I searched and didn't find what I was looking for, I'd like to know the schedule for JWST & Trappist-1 System. If anyone knows when JWST will be looking at Trappist-1 please let me know, thanks you
I found it :). There are three programs looking at the Trappist system in the first 12 months. Two programs have already started their observations, one looking for signs of atmospheres around all of the planets, the other looking at Trappist 1-c in particular. There's already been over 24 hours total of observing time, up till yesterday, with more time in the future, as yet unscheduled. None of the data from these programs has an exclusivity period, so once the data has been processed and analyzed, there should be not much delay in publication of the preliminary results. The third program is also looking at Trappist 1-c, with another 17 hours of observing time in November, but they have an exclusivity period of up to 12 months, so it could be a while before anything is published from that study.
@@EnglishMike Thank you Mike, From what I kinda remember Trappist-1 system is the number one object they want to investigate/study, I can not wait for these results. I can see us building gravitational lensing telescopes next if JWST comes up with amazing results, number one result being techno signatures. Trappist-1c is .90 "Earth Like". But T-1d & T-1e could also have life, I forget their index numbers but not far off "c"s .90 ... think they're both around .85 SETI has taken a very long hard look at the Trappist-1 system & heard nothing. Funny thing is we're looking for liquid water, & I heard somewhere these planets might not have any land, and be ocean worlds. Wounder how long it would take to mine asteroids so we can build O'Neil Cylinders to travel to Trappist-1 it being 39 light years away, they'd need to be generational ships & have radiation shielding & we'd most likely need to develop working nuclear fusion reactors first. And the robots to mine asteroids, and we could always use the mined out asteroids as O'Neil Cylinders, if we pick the ones with the right shape and made of the right materials. A very neat thing about these planets, their neighboring planets are so close they're bigger in their sky than our moon is for us. And they zip around their Sun, two closest planets a years in only hours long, and T-1f I think is year is 4 days. Having a planet larger than our moon rise & fall in the sky every few hours/days might be a bit unnerving. By the way in my opinion, building on Mars would just be us being stuck in another planet's gravity well, a dead planet at that, to me it is pointless, building O'Neil Cylinders makes sense to me since we can travel in them.

Holy dear, thank you Dr. Becky. You have answered many of the questions I have had regarding space and our understanding of it in this video!
If the micro meteor strikes continue at this pace and severity, is there any new projections of how long JWT will last as a high-level telescope
I would like her to address this concern, if it is one. I don't fear clickbait when the good Dr. informs us. Other internet folk don't have her extensive credentials, her nimble span of complex knowledge, her infectious enthusiasm, the power in the rigor of her work. She be good!
@@lancewedor5306 I'm hoping that any deformations that result - short of real damage - can be corrected with software just as was done for Hubble.
Sorry about the heat Dr Becky, hope you have a great rest of your day, and it starts cooling off soon for you.
Dr Becky: The sun is very hot
Me: This is the PhD Astrophysicist content I'm looking for
I love these space meme review videos when you do them, they're so fun and silly.
Is there a way in which we might put Hubble & JWST images together into one composite image? Or would it be too hard to add the false colours for it to make sense to our eyes?
I accidentally ran across your channel Dr. Becky. I love it. Thank you. I wished I had seen it earlier. I had some great Star Trek memes to send you.
I am not going to get that horsehead nebular meme out of my head for a while. That was brilliant!!!!
Absolutely! I just sent it to a friend who's a professor of optics at the local university. He loved it!
Love the way this FUN vid about memes gets into angular focus and the formula for it within 2 minutes.
Your meme reaction videos always make me think of how my husband tells me jokes and I laugh and then try to add some sort of commentary (I'm a sociologist) and he responds (not wanting to really discuss serious stuff), "Thanks for telling me why my joke was not funny, Dr. Academic!" In my brain, I have nicknamed your meme reaction videos the "Dr. Academic" videos, but unlike my jokester husband, I enjoy the humor and the explanations!
Haha! I love this 😂
I'm the one adding the extra commentary to memes in my relationship. I don't think she minds though. :P
I watched the JWST reveal on both NASA and your chammel. I had never seen a bonified nerd party before and was enjoying the feeds umtil I realized : Hey, I am watching too! Lov the channel thanks for all the effort.
"PhD students using this data that are not even born yet"... well, that kinda blew my mind just finishing mine lol
Brilliant video again Becky! Can’t wait for the new images. Just a quick mention, there’s a small issue with the audio :)
Hypothetical question: Would you, from the data recorded by hubble, be able to identify other artificial objects in space. Like, let's say an alien species at a similar point in technological advancement decided that now would be a pretty good time to launch a space telescope (maybe similar to JWST or Hubble), could these see and identify each other? And how close would they need to be for that. And how about bigger objects like spaceships or entire space stations. Or an alien version of the voyager probes.
Something like the Voyager probes would be pretty much impossible to detect, they are way too small. Something far beyond JWST's capabilities would be necessary. A telescope is of a similar size. It's hard enough to detect planets, and they are much bigger than a probe. And we cannot even see planet 9 after all this time, and that's somewhere nearby, in our system and it should be bigger than Earth. Just think of the "pale blue dot" image.
The issue with that is the sheer vastness of space. The closest star to us is Proxima centauri, which is about 4,25 LY from us. So, even if some aliens from there watched us with something good enough to resolve JWST, they wouldn't see it for another 4 and 1/4 of years, because only then the first light reflected from the satelite would arrive there. So unless you're a close stellar neighbour, you won't really be able to see anything for decades / centuries. And if someone from further away ( let's say 100 LY away, which is, BTW, in space terms actually reeeeealy close, since the entire Milky way is at least 100 000 LY across) saw earth, they wouldn't see what we see. They would see a pre-spaceflight species (hell, probably pre-flight species).
That's actually one of the solutions of Fermi's paradox - there are a lot of aliens around, but everyone is so far away from us, the light that left their planet while they are around didn't have enough time to reach us yet. Hell, the first civilisations on earth emerged probably no more than 10 000 years ago, so most of our own galaxy wouldn't see us for anything more than a smart animal even if they'd be able to see us at all.
The other thing is the size of the artifical objects. We at our current technological level are at best able to observe planets (if we're talking about anything outside the sol system) and even that is possible only because the planets sometimes pass between us and their star. So no, someone with on our technological level wouldn't be able to find JWST, unless they were in our solar system, and since they would lack the means of interstellar travel, that would assume they evolved in our solar system alongside us.
TL&DR
I'm 99,99% sure someone on our technolgical level wouldn't be able to find any artifical object in our solar system, unless they were observing from within the solar system.
From NASA's JWST FAQ : "[Webb] will be able to see directly the reflected light of [Jupiter sized] planets." "It will also be possible to see very young planets in formation, while they are still hot." "Webb will not have the resolution to see any details on the planets." (Of course, this refers to planets outside our solar system.)
So, JWST cannot see things as small and/or as cold as, say, the Earth. Things built by alien civilizations are right out -- even if they build something as big as the Death Star -- even if they build an artificial Earth! Only if an alien civilization were much, MUCH more advanced than us and built something the size of Jupiter (more than 10x the diameter of Earth and more than 1,000x the volume of Earth), or something as hot as a molten planet still undergoing formation, could JWST detect it. BUT, even if it could detect it, it could not see enough detail to distinguish it from an actual, natural planet.
@@D3emonic The true measure should be that of radio transmissions which we have only been broadcasting for 80 or so years. Thus no alien life form will be able to detect us until the 'bubble' has expanded into their sphere of influence and vice versa for us to detect them should they be capable of radio transmission/reception.
Dr. Becky tells you everything you need to know in this video to answer this question yourself. The Hubble doesn't have enough resolution to even be able to see Apollo spacecraft that landed on the moon 250,000 miles away as more than a single pixel. So, no, it isn't going to see another Hubble light years away. Spacecraft are TINY.
Always enjoy your videos, your enthusiasm is infectious. ❤️ ya
I did that Spider-man meme just after the images were revealed, except I did it correctly. He sees better without the glasses after being bitten by the spider, so that's where the JWST image should be.
Your new JWST merchandise is awesome. I ordered the JWST reflection t-shirt. I would have bought the JWST first science image t-shirt, but I think the lower right image should have been moved outward to make the images form a smiley face.
One giant leap for meme-kind.
Fantastic explanation of the resolution equation in the context of the telescopes in question.
Are we about to reach a point in time when there are not enough people on this planet to study the data from billions of galaxies observed by JWST and future space telescopes?
no worries, AI is training hard every day, data is what AI lives for so we can live for memes 😝
So glad you haven't burst into flames, yet. Really love and appreciate what you do. Keep it up. And do whatever you can to stay cool.
I like these spontaneous looking up information. don't have to be very produced look and feels like you're just talking to us :).
a neat trick to keep cool is to put a bucket of ice water in front of the fan. it'll keep you cool until you need to refreeze the ice again.
I always love when scientists covering really old or large timescales or objects say only because its always so crazy what they say next but somehow in the grandscheme of things it is only.
Hi Becky, I really like this episode -> using a meme as a "bridge" for the explanation. 👍👍
Hey, can you PLEASE make video about the anti Dimensions Theory
At 15:51 it looks like there's a Hoag's object/galaxy in the background as well. Nice
Hey Becky.. Thanks for an another interesting video. Love from India. ❤️
1:17 Glad to know I'm not the only astrophysicist who appreciates a great SpongeBob meme! Also appreciate the classic SpongeBob narration transitions throughout the video lol
Yay I was in the video! I'm big time now 😁
Great stuff, Dr. Becky!
Thanks for the awesome meme!!!
So you turned the fan off for better audio and then had low battery issues on the mic. You have my every sympathy. Your dedication to your channel is admirable.
Dr. Becky.. you make this stuff fun.. thanks for that..
13:37 - question about the lensing stuff, and in particular where we get multiple images of the same object lensed in different ways: when we're building our "map" of things from that, is it also possible to sort of back-compute an un-distorted shape of what the object would look like, if not lensed?
Just what I was wondering when I saw some of the images on a video the other day. Also about how they can tell which are duplicate images of the same galaxy or if it's possible to get 2 images of a galaxy as it was at different times because the light takes longer to go the other way around the closer objects. Perhaps a time difference of thousands of years apart or hundreds of thousands (or millions) of years?
@@yahccs1 There is always a time difference when the light takes different routes. But when you have a candidate for a reconstruction, you will reconstruct a picture of the galaxy from each image independently, and try to make a progression fit for how the bright points in the galaxy ought to move. So: Possible, but also very processing heavy, plus it takes a hellalot "Say, could this one be a flipped and bent version of that one?" to even get started. Becky's not kidding when she says there will be PhDs earned by people not yet born, on the data Webb collects.
:)
@@yahccs1 interesting question. I haven't done the math (nor do I even have the expertise to), but I suspect the difference in time would be _much much_ smaller than what you're talking about... seconds to maybe minutes, at most, I would think.
Hmm, well, looking up Einstein radius or Schwarzschild radius could be informative. Indeed, on wiki's Schwarzschild_radius#Black_hole_classification_by_Schwarzschild_radius, one can see a radius of 400AU listed. That'd be 400*~8.3 =3320 light minutes, I guess? Or about 55 hours... which I'd say would be an estimate for the _maximum_ delta between the two arrival times. Could still be interesting in some contexts, maybe, but I think it'd fall short of what you're talking about, sadly.
Hello There! always with the best videos!
The noise floor on your audio track was a bit high. Keep up the great work Dr Becky 🤩
yay another meme review! Hoping for another one, soon
Bought your book! Have you ever listened to the Nightwish songs about space?
You've been peak space nerd as long as I've been watching your videos. :) this is a good thing.
dr becky please do an overlay review of the cloud at 1.42 . there are new stars in the JWST image and since the hubble photo the cloud has actually moved in areas as well . i like your approach to and knowledge of space and how easily you explain to the novice .
Wonderful to appreciate the humor! Keep it up!
We are also dealing with a heatwave over here in the states. I’m in Northeastern region the U.S. and it’s been like a high of 95°F (35°C) this week.
All memes were hilarious! 😂
Btw, Dr. Becky could you please make another part of "A day in life of an astrophysicst". A humble request. :)
Telescope related. I’d be curious to have you talk about the observatory on La Palma since the volcano stopped erupting. When did it get back to routine operations?
Becky, are you planning on making a video addressing the recent damage the JWST has suffered due to the collision and how it may impact future researches?
I love that I found you recently (I don't remember how) after recently getting more into physics and that you also watch Kara and Nate 🤣
Edit: spelling
Award winning bloopers segment Dr. Becky!
I'm 5 minutes in now. Loving the memes so far, but living the questions and straight solving the questions even more ^^
that was a nice video, really excited for all new discoveries awaiting us!
Cool explanation of the resolutions of each and their overlap.
I rarely watch the bloopers but this time I did. Don't worry pretty lady, we're not here to watch or judge your hair 😉. Thanks for doing what you do and doing it so well. 😊
Some amazing pics and discoveries due in the next years but what about the reported damage it sustained recently?
Another great video as always. Though there was a lot of white noise throughout the whole video for some reason.
I tested my setup to make sure it wasn't me. Tried speakers, headphones, reloaded the video, played different video, etc. Only hearing it on this one.
That was probably her fan. She turned it off briefly at one point.
Don't worry. When you get older, you'll stop noticing these things...!
Read the popup at 0:13 : problems with her mic (low battery).
Static audio noise like this is very easy to remove. Just use Audacity to filter our the noise after sampling it in a "quiet" part of the audio track.
Oh wow. I didn't realise that you filmed this on one the hottest days of the year and had to turn off your fan to do it. That's dedication. Thank goodness it's cooler now.
5:00 High-resolution horse head very exciting, but worth noting that if University of Arizona is behind the proposal it is surely related only to cheerleading
You are good moods Dr.Backy you're made me smiling
I remember the photos of the Horsehead Nebula when I was a kid. It's my favorite, just because, and that first meme was great. Thanks.
The only part that bugs me about the Spider-Man meme is that it's backwards. That's the part of the movie where he realizes he has super spider vision I guess, and that his glasses now make his vision blurry! I get why they used it for the meme just because of the imagery, but I can't help but think of how it looks from his end after having gone through spider puberty.
Iirc, the actual light collecting sensor on the HST is ~7 megapixels
Could you make a RUclips Short explaining the gravitational lensing with the wineglass example so it can be linked to when someone asks about it?
love your passion for the universe. thanks for sharing with us
I am really looking forward to JWST looking at Orion. I have a 175MB image of it from Hubble but I can imagine how much more details JWST will reveal. I wonder if we will be able to work out what the cylinder shape is that was spotted in the image - photo artefact, real object, tinsel, etc.
When they state the observation times for images, is that the total time for all filters used, or the per filter time? That would kinda assume the exposure time for each filter is the same or nearly so, is that the case? The JWST 'deep field' used 6 filters, which would mean each filter was the 12+ hours or 2+ hours.
I don't know how optics work so why is it that we get pictures that aren't in the shape of a hexagon similar to the shape of the golden mirrors of Webb? And in the center there is no mirror so there's a hole so why do we get complete images without a hole in the middle?
Because you don't know how a reflector telescope works. Do a web search to understand its general operation then you will understand.
@@txmike1945 I asked for answers. Not instructions.
@@marcuscarana9240 You seem spoiled, you want everything to be handed to you with no effort on your part. That isn't a good way to try to navigate through life! Take some responsibility and put your thinking in gear.
@@txmike1945 Your comments provide no answers to my questions. Shoo.
Dr. Becky please also comment on the accident of jwst with microasteriod, recently in news ,will it cause harm to jwst further in future .
I have built a fully operational warp drive in my garage. Which star system should I head toward first?
Listening do you babble, Becky… I kept repeating the same sound. Mhum. Truth. Total respect, and I love your tubers!
4:40 the one I personally am anticipating, bearing in mind looking at the same things again versus looking at entirely new things is kinda a big deal…but the one I’m looking forward to is the nebula/dust cloud dubbed “the pillars of creation”
Love the video but please investigate that static grey noise in the mic audio.
Yeah did you not see the warning at the beginning of the video?
@@DrBecky ahh whoops!
Always great to have a fun video from you! One topic that might be worth a dive as I had no idea about it until I saw an article pop up in my feed. The concerns of micro-meteor strikes and how one of the mirrors already took a decent hit! BUT they were able to offset the mirror to null-out most of the impact's effects? Like.... how is that possible? If all the mirrors have to be focused at the same location to get clarity and resolution, how can you adjust the focus of one mirror to account for meteor impact damage? Then there's also the concern of if meteor strikes are going to be more common than originally simulated, thus potentially reducing the life-space of JWST?
You know, that is all good questions, it would be good to hear from someone who actually knows. But bear with me to share a frustration, especially on a site like this dealing with astronomy. The use of correct terms. A meteor is a flash of light as a meteoroid gets burned up entering the atmosphere. If part of it survives to the ground we call that a meteorite. So the gist of all this is a meteor cannot hit a Webb mirror. It was a meteoroid. Now your first reactions might be "why is this guy so nit-picking?" Well as I started out this is not some social club discussion, it is an astronomy and astrophysics channel so we owe it to each other to use correct terminology.
These are hilarious! And I love your reactions to them, as well! ❤️❤️
13:20 Could you use some mathematical transformations to reverse the distortion of theses images rendering them back to their original shape?
2:30 So would this be angular resolution of the optics and the sensing instrument ,detectors, together? Also Is this different for the spectrum detectors VS the image detectors?
It's based purely on the size of the mirror - the detectors and intermediate optics ultimately limit the resolution we see; some sensors even intentionally undersample the mirror because they value sensitivity over resolution...
Dr. Becky, I searched and didn't find what I was looking for, I'd like to know the schedule for JWST & Trappist-1 System. If anyone knows when JWST will be looking at Trappist-1 please let me know, thanks you
I found it :). There are three programs looking at the Trappist system in the first 12 months. Two programs have already started their observations, one looking for signs of atmospheres around all of the planets, the other looking at Trappist 1-c in particular. There's already been over 24 hours total of observing time, up till yesterday, with more time in the future, as yet unscheduled. None of the data from these programs has an exclusivity period, so once the data has been processed and analyzed, there should be not much delay in publication of the preliminary results. The third program is also looking at Trappist 1-c, with another 17 hours of observing time in November, but they have an exclusivity period of up to 12 months, so it could be a while before anything is published from that study.
@@EnglishMike Thank you Mike, From what I kinda remember Trappist-1 system is the number one object they want to investigate/study, I can not wait for these results.
I can see us building gravitational lensing telescopes next if JWST comes up with amazing results, number one result being techno signatures.
Trappist-1c is .90 "Earth Like". But T-1d & T-1e could also have life, I forget their index numbers but not far off "c"s .90 ... think they're both around .85
SETI has taken a very long hard look at the Trappist-1 system & heard nothing.
Funny thing is we're looking for liquid water, & I heard somewhere these planets might not have any land, and be ocean worlds.
Wounder how long it would take to mine asteroids so we can build O'Neil Cylinders to travel to Trappist-1 it being 39 light years away, they'd need to be generational ships & have radiation shielding & we'd most likely need to develop working nuclear fusion reactors first. And the robots to mine asteroids, and we could always use the mined out asteroids as O'Neil Cylinders, if we pick the ones with the right shape and made of the right materials.
A very neat thing about these planets, their neighboring planets are so close they're bigger in their sky than our moon is for us. And they zip around their Sun, two closest planets a years in only hours long, and T-1f I think is year is 4 days. Having a planet larger than our moon rise & fall in the sky every few hours/days might be a bit unnerving.
By the way in my opinion, building on Mars would just be us being stuck in another planet's gravity well, a dead planet at that, to me it is pointless, building O'Neil Cylinders makes sense to me since we can travel in them.
As we go back further and further in time, the memes just get better and better! Thank you universe.....
Why is it, when someone means "farther and farther" they write "further and further?"
