I remember looking forward to this telescope back in high school. I'm now 35. No one at work gave a shit, but I was so excited when it launched. I've been branded the "space nerd" given my excitement about "some space shuttle" 🙄 but I don't care. This is an incredible feat of engineering that still continues to dumbfound me without having even taken a single photo yet.
Webb is amazing!
i’m in high school and i’ve been labeled a space nerd as well for being excited for the launch, but when webb finally starts functioning everyone will realize why we cared so much.
You are not alone brother, I was super excited about this telescope!!!
People are dumb. Don't give two shits about literally how our universe was created, the first stars, the secrets behind our existence, the history of our universe, habitable planets. Then be hyped about some playboy carti concert.
@@blazo8700 they think they are the center of the universe becuase it fulfills their need to be important when in reality we mean nothing
I have a family member who was one member of a team among many, many engineers that worked on and relentlessly tested the deployment of the solar shield. Whenever a stage of James Webb's deployment was completed, it just made me that much more excited. It's incredible, if not miraculous that not only did nothing go wrong, but the telescope's lifetime is extended from original projections.
Whos your family member?
Cool!!

Without a doubt, SEA produces the very highest quality videos of scientific subjects. Every one of the productions astonishes in its clarity of language and command of cutting-edge knowledge. Ten thumbs up!
Agree,it is a high quality channel !
I think astrum and pbs science are up there too
Why is a 14 year-old narrating this?
Event Horizon, not just elementary stuff.
World Science Festival?
He kinda sounds like a valley girl tho...
My dad was one of them that built one of them rockets in 1996. So my dad will always be rememberd that way even after he passed away 10 years ago 😁
Very few people get the opportunity to do something in life which leaves a mark or a meaningful contribution to future generations. Your father was one of the lucky ones :)
Can't wait to see some of the first photos from the JW telescope! It really is amazing how advanced it is and what it will be able to show us...
Me toooooo. My lady doesn't understand why I'm so excited by this but imagine everything Hubble has learned but 20-30 more years of technical advancements and scientific know-how. I'm beyond excited for this next era of space exploration.
It just feels par for the course in this timeline that it would break somewhere along the way with all of this hype but so far I have been proved wrong and that makes me elated. I trust that all the scientists and engineers did a pretty much perfect job once they realized nothing less would fly...I cant wait either!
Man, imagine how horrible it'd be to die before the images come out...
@@planescaped don't you put that evil on us Ricky Bobby
@E Van You're not gonna be able to see much else it is what it is there's limitations to this kind of stuff
I just want to thank our French partners for flawlessly launching JWST into the precise trajectory it needed to be to reach L2 with little to no need for correction. Tu es notre plus grand ami et nous t'aimons tendrement.
This video gave me so much hype for JWST, keep up the good work!!
@Black_No_Sugar Lay off the coffee there bud.
@Black_No_Sugar 'ight
Seconded!!
Funny seeing you here.
Wonderful work here SEA. As usual. You have created my absolute favorite cosmology channel on the entirety of the internet. Thank you very much.
Great namesake, fantastic movie.
this one is hand down the best! i can barely think of anything that even comes close!
@@cobrazax Yeah, PBS Spacetime is too obtuse and over-complicated and often kinda poorly explained/presented (IMO), and Scishow space is the opposite, over simplified, sensationalized and derpified for the masses.
Anton Petrov and SEA are my two favorite space shows I've seen. Though Anton does tend to dither on too much in an effort to hit that golden 10 minute mark but I don't hold that against him.
Scott Manley is good too.
@@planescaped
Well melodysheep is great too, but i dont think they focus on exactly the same things. He also doesnt explain things with his own voice, if any.
@@cobrazax melodysheep’s videos are of a quality I cannot attain. They are so flawlessly produced I have no problem in admitting they’re head and shoulders above my content, even if our two approaches to content differ a lot. I try and get better with every video though so hopefully in the long, long term I can get to somewhere close to that level. But that’s a way off yet.
what a time to be alive, we get so used to talk about history, things in the past, I can't wait to see what comes next.
@Black_No_Sugar It has already arrived at the L2 point. Currently its cooling down to operation temperature while getting all 18 of its mirrors focused to be able to take the first photographs by may-june this year. Every single operation so far was said to have gone according to plan. If you ask me, there is no price limit for exploration. Money should never stop innovation.
Finally, an informative science and exploration channel that gives a quality analysis of the JWTS instead of click baiting it every 3 videos.
Not a star nerd, had no real clue why everyone is so excited about James Webb, but I do now, thank you so much for this well made and extremely informative video. I too am now excited for what JW will see.
I couldn't imagine what we can learn from looking even farther back into the universe's lifecycle! Excited doesn't quite encapsulate how i feel about this telescope!
I don’t care what we see, it ain’t worth the money spent on it.
Nice bait try again
Excellent! I was born In 1958 and have grown up during the entire space age... this mission is the culmination of everything that came before it.
Class of “76” !!!!
I could resist the urge to say that most all things are the culmination of what came before but I won't.
I have been waiting for JWST for so many years. I couldn't believe it when it launched. My stomach was in my throat all through the deployment phase. Now we're safely orbiting L2, and things are looking good. Finally, James Webb is where it belongs, instead of sitting in a lab after endless delays.
I loved the book but I’m assuming your username is based on!
@@leonettab7479 Slinky Malinki opened the door....
The James Webb Telescope is so powerful & can see so far back in time it can see Federal Agency NASA’s original promised launch date & budget. In 1996 NASA promised the Webb telescope for a 2007 launch with a $500 million budget. NASA delayed JWST launch 13 times. Current Cost is $11.3 billion to develop, $878 million to operate. 14 years & 1700% over NASA’s promised budget. it's important to remember that, despite the scientific and engineering triumphs, JWST was another serious Nasa management fuck up & yet another irresponsible schedule/budget disaster, 14 years & $9.5 billion over budget. Private industry could have produced & launched the JWST telescope at 1/10 the price in 1/10 the time, had it in place 15 years ago. Nasa is government & Government is greed, waste, incompetence, & corruption.
What else in your throat?
@@warrenwhite9085 I'd like to touch on what you mentioned about the private industry being able to produce results at one tenth the price and time. And that is...you are absolutely correct about that. I am personally extremely relieved that SpaceX exists.
I’ve been subscribed for a while now and I can’t believe this guy isn’t at a million plus subs. This is one of the best astronomy channels on youtube and whenever I get into a conversation about space with people I tell them to come check out this channel. Keep going bro, Ik you’ll get there soon.
@Black_No_Sugar Quit spamming this crap, you have no idea what you're even talking about. Go back to "proving" that the moon is fake or doing your schizophrenic essays about JFK.
I watched this on a dreary and particularly wet Sunday morning and it lifted me into an excited state of deep wonder and gobsmacked fascination, making me forget about my worldly problems for a good 35 minutes. Thank you so much for being able to do that and giving me something to look forward to in the coming years.
Hello Bro Would you want to Know that something is Beyond our Imagination.
Another exceptionally high quality production. Beautifully lucid explanations as always. I loved the Transit Method graphic.
@Black_No_Sugar Murphy's Law is further proven by your existence.
It blows my mind how complex and difficult it must have been to build this telescope, especially knowing that once it's launched, that's it. There's no going up there to fix it. It makes total sense that it took so long and ran so far over budget. It must have been the most stressful 2 weeks of those scientists lives when it launched.
Can't imagine pouring so much time into it n waiting those 2 weeks. What a great feeling when it all went to plan tho, such an amazing piece of engineering. Baffling what we can accomplish when we put our best n brightest on something, plus reasonable funding. We can do anything with a few billion n some geniuses
I'm so glad I only knew about this telescope for about a year. Had I known about it, back when the project started all the delays would have driven me insane because of how exciting of a project this is and how eager I am to know what it discovers!
I feel bad for those who have been waiting since the beginning and the torture they've endured 😭
This wait for the photos is killing me, I can’t imagine waiting 15 years for the launch and then having to hold on for a few more months to capture photos
As far as i've heard, the ariane 5 performed so perfectly on launch, that the jwst needed less fuel than hoped to reach L2, so its predicted lifetime is now over 15 years!
Great Video about a amazing piece of technology :)
I’ve heard upwards of 20 but that HM7 upper stage is pretty impressive for efficiency and exact speed insertions.
I was away spending Christmas with my grandad and staying in a wee cabin with my parents. I insisted on waking my mum to watch the launch because this was one of the most momentous events in my lifetime. I'm still amazed that it went so perfectly, it's almost unbelievable.
Yours was a wonderful, passionate homage to the JWST and that telescope, its designers, scientists, and engineers are due great praise. However, I would differ slightly about the "new age" characterization for the JWST. Rather, I would see the JWST as an extension (amazing, complex and awe-inspiring!) along the same direction of optical telescopes we have been on for centuries. My candidate for the "new age" in cosmology is the first generation of gravitational wave detectors--LIGO and VIRGO--as they introduced a whole new dimension ("listening" as some call it) to the discovery of the universe.
perhaps in 30 years we will have an array of space based LIGO spanning hundreds of thousands of km, able to detect what is too wide to measure from Earth. So far, LIGO only measures black hole collisions but we could be detecting far lower frequencies from a space based LIGO.
Yes! LIGO! Once again proving that 'ol Uncle Albert was never wrong 😊
Have you also heard of the new LIGMA telescopes?
only legends remember SEA1997
I got tears. This is history in the making. And this here is your best video so far. I am so happy this channel exists. Thank you so much. ❤
I cannot express how much I love your videos... Your style of narrating, the delivery with all of its contents is so amazingly done! Thank you for making so informative and enjoyable videos of such high quality about one of my favorite topics in existence!
I heard recently that the expected operational life is now 20+ years, and that it's pretty much in the bag if nothing breaks. I know it's a zero-sum game with the fuel, and they saved back a lot by the perfect launch. But 20 years ... that's even better than I expected.
I thought that, at L2, the earth and sun's gravity both pull the telescope in (roughly) the same direction, with that collective pull being offset by the centrifugal force of the telescope's orbital loop (ellipse). And the centripetal force in the secondary orbit around L2 derives from it being pulled back toward the centerpoint of that same collective linear pull, of the earth and sun. And it's pretty cool that neither gravity nor the centrifugal force are actually forces at all.
With new technology and development, and the focus on space travel, Im sure there will be a practical way to service Webb in a decades time, and even replace its parts with superior instruments.
Also keep in mind space debris could hit this telescope at any time.
@@CryWolfFilms it's true. I do think (though I'm not sure) that the kind of chronic dings that (so I'm told) have accumulated over the years on ISS are more characteristic of low Earth orbit, as opposed to Webb's big lap around L2. That said, you're right, it could surely happen. One such ding on the primary mirror and we do the unhappy math. Now that you mention it, I guess I don't know what's actually dinging ISS -- i.e. is it human-made junk or natural particles??
JWST had such an efficient launch that it is now expected to last around 15 years now.
Thanks for the way you concluded this video. It is so critical that the next generation of explorers be excited and inspired to continue the journey.
I've been following the JWST's progress over at "The Launch Pad" and it truly is an amazing piece of engineering, bigger than the pyramids.
The near perfect launch on Christmas Day actually extended the telescope's potential lifespan to up to 20 years.
What an amazing documentary, so glad i clicked that video! Great job, i feel so honored to be part of this journey!
i have watched so many James Webb videos but i know after this i will have learned waaay more!
I can't remember being this excited about anything in my whole life. And I'm 61. It's a phenomenal achievement and I can't wait to see what it discovers. Hands down to those 140.000 scientists and engineers responsible for this magnificent instrument.
Fantastic work! Every video you drop is a jewel!
Congratulations to the engineers and scientists at NASA, CSA and ESA for their monumental achievement. I can't put into words how exciting these next few years are going to be!! :D
Wonderful narration and production as always dude. Keep up the great work!
Somehow the CSA didnt get any credit in ur comment sad times indeed
@@halinaqi2194 due to me being uninformed. Sorry about that. Didn't mean to leave Canada out!
Ridiculously absurd.
Thank you for this inspiring and beautiful video about JWST. I love your work.
7:40 - send a third stage guild navigator to Kaitain to demand details from the Emperor. The spice must flow!
Outstanding production work on this chronology of JWST 30 plus years in the making. It is astonishing what “we” are capable of doing at this stage of human history, and makes me wonder how far we will be able to advance the frontier of knowledge in the next decades thanks to the exponential growth and convergence of technologies.
I love these longer videos man. I will watch them over and over again before bed. You have an incredible talent and create some stunning compositions. Keep up the good work and thank you from New York!
This telescope is a prime example of what can be achieved when the best and brightest of all our nation’s space program’s work together.
I remember listening to one of my American buddies stating that he thought it was foolish for the ESA to handle the launch instead of NASA.
Man I was happy to see the ESA help Jam his foot right in his mouth. I mean having such an efficient launch that the ESA saved enough fuel to possibly extend the mission by a decade.
If the ESA hadn’t contributed a penny other than handling that launch it would’ve been worth it as 5 to 10 years of extra telescope time with Webb is darn near priceless to Astronomy!
Amazing!
This is probably in my top 3 favorite channels on TH-cam. Thank you for all your hard work to bring us this excellent content.
Having seen the initial image used to check the individual mirror position correctness I can say the picture was mind blowing. So so so so much clearer than the other infrared telescope and zoomed in so much further and even zoomed in it’s still so clear. That test image discovered a heap of new galaxies as well and I bet someone is measuring and classifying those already.
I've seen several YT videos about JWST and must say yours is easily the best one.
Also, I presume you've seen the official JWST poster, but if not, I urge you to do so. It's a masterpiece. I had to order a professional print for myself.
Fantastic job. You fellas are crushing it with regard to these informational videos.
Those first photos from JWT will probably be as mind-blowing to us as the first images of Earth were to people in the ‘60s
I've been following the jwst project since I was in middle school, and my excitement only continues to grow. Fantastic video.
the man behind SEA is a genius! best space content on YT.. unbelievable
The liftoff guys speech about the birth of the universe was really good
I still remember when I first laid eyes on the full size hubble deep field. It took such a long time for my dial up connection to download, but by the time it was complete I took a couple of puffs of the strongest weed and just looked in shear awe at it. That image broke me down to the deepest parts of my existence
I cant wait to see webbs "Pillars of creation" moment but the thing im most excited for is the unknown unknowns. The questions we are not smart enough to know to ask but may get answers to, and the next set of questions that leads to.
You can always depend upon SEA to produce the finest science videos. This JWST episode is simply fantastic! Thank you, SEA
I’m so fucking lucky to live during this. I set an alarm for 4am to watch lift off and spent Christmas with my very loving but annoyed girlfriend of over 10 years pacing around her moms house watching everything go down live. I’ve been waiting ever since I first heard about this “Mega Hubble” in 2007 when I first started really being interested in space. Humanity can do some good every now and again.
Perfect. Exactly the information I wanted to learn. I watched 20 other videos but none of them covered the material we wanted to learn. None of them covered that next level of detail that this video does.
Thank you so much! Please keep doing more, your channel is just so incredibly good.
You rock SEA !
This video is eloquently and beautifully done. Always happy to see information given in a way that can make the average person excited about science and physics. I'm having a viewing party when the first images come back! So much to look forward to! Thank you for this great video. Best wishes!🙏🥰
"From a tropical rainforest to the edge of time itself, James Webb begins a voyage back to the birth of the universe." - NASA Dude.
Easily the best sendoff in unmanned launch history.
Dude your videos are that kind of candies that you save for later. I'm allways excited if you come out with a new one. I don't watch it right away but when I place myself in a nice comfy space and let myself be amazed...
Keep up!
Great video. The only thing I'd disagree with is the sentence you ended the video with: "For hundreds of years, people will look back on Christmas Day, 2021, as the start of the new age in astronomy." No way. If there's a telescope-related milestone date that will be thought of for hundreds of years, it'll be the launch of the first space telescope. The JWST is obviously a tremendous upgrade, but it's a stepping stone after the Hubble telescope. Ask yourself if you can name the crew on the second manned moon mission if you need evidence.
So you think that there can only be one "new age in astronomy"? And Hubble wasn't the first. OAO-2 was the first imager in space in 1968, an ultraviolet telescope. The original OAO (cleverly named Orbiting Astronomical Observatory) had failed in orbit in 1966 and never returned any data. There was an OAO-3 in 1972 and a whole bunch of others before Hubble in 1990. By the way, that Nancy Grace Roman space telescope (née WFIRST) that you are going to hear a lot about? She was NASA's Chief of Astronomy at this time. Other countries flew space telescopes before Hubble. The Netherlands' first satellite in 1974 was a space telescope. Hipparchos, the ESA survey satellite, whose astrometry data catalog bears its name, flew before Hubble.
Hubble was the first of the "Great Observatories" program. I'd call JWST the upgrade to Spitzer, another Great Observatory, rather than Hubble. It can't see very far into the visible and not at all into the ultraviolet. Its bread and butter is IR.
Pete Conrad. Al Bean and Richard Gordon. I can name them all.
😎
Idk there has been pretty hot talk lately about James Webb
Let's see what it manages to show us. *That* is what will ultimately cement its place in history.
I do have hopeful expectations.
I think it will be thought of as more than just Hubble v2.0
@@Markle2k nope. Didn’t say there could only be one age of astronomy. The past gets compressed as you move into the future though. Can you name 10 people who were alive in the 1500s without using some kinda reference materials? There aren’t that many dates that people have memorized related to astronomy. Do you know the launch date of the Hubble telescope off the top of your head? The JWST is a huge upgrade. I’m excited. You’re probably excited. We are the sorta folks who watch SEA videos though. I was just saying that if there’s any telescope that people are still talking about in a few hundred years, it’s gonna be the Hubble. Something unforeseen could happen. Maybe the JWST discovers undeniable proof of alien life somewhere or it’s course-correcting thrusters fail and it falls out of orbit ends up crashing into the space station or something. A miracle or tragedy could make it memorable for sure. If all we get are higher resolution images or a look a bit further into the past though, there’s no way this project will be something people are familiar with in, like, 2350 or something.
Best content there is, wonderfully explained. We're so fortunate to witness all of this.
Your videos are unbelievable, the best quality of anyone!
Probably the best channel on TH-cam. Simply outstanding.
Great, great video. Thank you for sharing such informative and high quality content with us!
This was beautiful. I can't wait to see the first images from Webb. We are going to learn so much it might be overwhelming for some. This is indeed a special time to be at in the universe, I just wish humanity would come together for the greater good so we can learn even more and even possibly (if there is intelligent life) finally figure it all out. Humans can do amazing things if we all just come together.
I always look forward to new content from you! Thank you 😊 🙏
Two friends came by to say happy Christmas, both in a hurry to get home and watch the launch, but neither of us knew the other two guys was going to watch it. Long story short, my tv was on and we were all space nerds that ended up watching it together.
Absolutely love your content! Thank you for everything you do!
Favorite video on JWST I've seen. Clear, concise, and informative. Thank you for putting so much work into it!
Feels microscopicly broken down to digestible bits for retention. Love it
These are the best space documentaries currently on the net , keep up the good work
Your content is incredible. Thanks for the effort you put in to each and every video you post. Every single one makes me feel like a child again full of wonder and curiosity. I hope to see many more of them in the future.
i think they should name the next telescope or satellite SEA, in honor of this channel's hard work and dedication to the field...
Looking forward to the future.
Great job as always
In my humble opinion your voice is by far the best documentary narrative voice in existence. Thank you for continually uploading, SEA!
Really good work! Informative and upbeat. Really enjoyed the video. Thank you.
loving the content lately, thanks a ton
I have been waiting for this for years! I am so damn exited for the first pictures!
Possibly the best Webb documentary and universe formation lesson I've ever seen. I learned so much. Bravo!
I was hoping you would have made a video on this, I heard about this project for the first time last year, the details alone were nuts between cost and time of production.
Excited to see what secrets we can uncover from the universe!
honestly ur videos are amazing and well made!! I didn't even know Webb took so long to be developed, even b4 I was born! ( I was born in '05)
Great narration and explanation of what the James Webb telescope has done and will do!!
This video was fantastic. The aspects of the project which it covered were all super relevant, and it paid due respect to all those involved for their incredible achievements. Most importantly, it felt like the information was succint, which made for an enjoyable experience for this layman! Can't wait to view some more of your videos. Awesome stuff!
You truly are my favorite to watch and listen…out of my many ppl I have subscribed to. You Are straight and to the point but not boring! You really are the best
I adore your content. Never stop bro. 🤜🤛
I was actually wondering if SEA had already uploaded a new video since the last one three months ago, then I came, checked and realised my expectations were fulfilled hahaha Now after watching this new piece of information, I feel even more excited about all the descoveries and amazing new-coming images we'll see from this groundbreaking masterpiece, the James Webb Telescope UwU
Never expected an UwU in this comment section 😂
I really like the way you express, it makes it possible for people like me to understand subjects as complex as astrophysics, i really admire you for the work you invest to get the best video quality i have seen about this subject. Thank you very much
You make the kind of content that helps answer and look further into the deepest questions of our existence...This is my way of saying I'm very grateful to have come across your chanel and content... Keep it up bro... Bulelani from Cape Town South Africa 🙏🏽

I genuinely love your channel so much, please continue to make videos these are so amazing!
Oh imagine if we could travel in time to 1608 and bring Hans Lippershey back with us to today. I think he'd be impressed.
My only hope is that the public does expect JWST to deliver more stunning images than Hubble.
It can't and won't.
Its immense mirror is made to deliver good resolution at IR frequency, but due to the physics of light, its absolute angular resolution is actually much worse that that of the HST (about 40 times worse).
I do worry about the likely PR disaster time-bomb this will create within a year or so.
The "seeing further, but not better" aspect is not discussed enough, and the size of the mirror is way oversold by media, abundantly belittling the fantastic HST, and giving, I believe the false impression of a "quality quantum leap"...
With the telescope in space, I understand it will not be an enormous issue, but it could handicap funding of further developments (such as unmanned maintenance), shorten the life span of the program, or the development and launch of later space observatories.
Even the spectacular images from Hubble were false coloured in wild colours, ostensibly to better show data but probably also to please the public and secure more funding.
@@Tom_Quixote Well... "False colour" yes and no.
Yes, all the pictures done by HST were technically in B&W, at given wavelengths, depending on the sensor and filters used. But wavelength = colour.
And so no, as HST's detection range is still centred on the visible spectrum (spreading to with near IR and UV as well), so, in that sense, it is not completely "made up". So what the picture-processing people of nasa did was definitely "enhanced for effect" in some cases, but not completely psychedelic nutyness either.
The main issue however: JWST will definitely see stuff that were invisible to HST, but it will not be able to provide the same amount of fine details and the same type of awe inspiring poster material. Remember that JWST will be looking at targets much further away, and therefore much smaller than the ones HST sees, couple that with its lower intrinsic resolution, and it means a trade of "artistic quality" for quantity and scientific value. Great stuff, but I am afraid the hype lead the public to believe something else.
For SEA videos, I hit the like button before even watching them They're always amazingly good content.
Best in-depth JWST video I have watched... Just Brilliant 🙂. The story telling art is mesmerising. Thank you so much for your efforts SEA.
I wonder what the JWT would find in places like the Boötes Void. Maybe it's not so much of a void anyway, but filled with some of the Universe's first galaxies. I'm so much looking forward to the first images from this incredible piece of engineering. And a big thanks for another fantastic video, SEA. Greetings from Denmark
Yeah, I so want for it to look into the big voids like hubble did in it's time... can't wait
Another Great Video. #SEA
SEA and David Butler are two gems of astronomy topics on TH-cam , i respect the effort they put in their videos
I've been present from the creation of the space age and the earliest touches of space by man. From the X - 15 through sputnik and Glen. From one small step for mankind to hubble and the dreams of returning to the moon. I've watched and dreamed of space and what we could learn. And learn we did. But nothing like what we are soon to learn from James Webb. How amazing to live in these times.
Imagine if America didn’t spend 1.5 trillion developing a jet that still does absolutely nothing for anyone. Could have over a hundred of these things looking everywhere
I get your point but but easy to say in hindsight. We can never khow how something will turn out until it does. What if the laungh rocket had exploded.... would you then say $10 billion was wasted and we should have used that money for this or that?
Given amerikas technological and scientific decline, I had doubts the decaying and decrepit uS would ever be able to get this off the ground. Clearly, the ESA was doing all the heavy lifting on this one. Still, way behind schedule and way over-budget are features, not bugs, for projects where amerikans are involved. I doubt the uS will ever be capable of anything other than relatively simple projects of very limited scope after this.
It sounds like you had a messy relationship with the United States - and are still bitter about being dumped.
@Jay Tee Not as focused on genders as you seem to be?
Sea, your work is beautiful. Its breathtaking, meditative, inspiring and most of all I love your pacing as you tell the story. It is mesmerizing. Your work is as worthy and better than many full budget PBS documentaries. Thank you!
always a good day when SEA released another video. Great work as always! I tell everyone about your channel and videos.
