7:36 "I am the star". Yes you are Dr Smethurst.
Quit simping :3
Yeah! I did my degree dissertation on the JWST. 10 years ago... Wow. :) Can't wait for its launch...
hey how much does it weight approximately? is the delays because of constraints of the particular launch vehicle?
When in space it won't matter how much it weighs! ;) And delays are inevitable when working on a multinational, multi billion dollar science venture. The launch vehicle is well established, so that shouldn't contribute much to delays. It's more likely that funding isn't always steady, combined with complex cutting edge science technologies would cause project planning to go awry sometimes.
okay but my quest ion how muchit weighs in space. its weight on earth DOES matter.
So you dont know?
I know, you're right it does matter! I couldn't remember and thought it was 5tonnes or so. But a quick search and according to the website it's more like 6.2tonnes: jwst.nasa.gov/facts.html
thx man.
Dr Smethurst is great addition to the Sixty Symbols contributors. Great video, thanks.
Kieran Garland - Agreed. She is a great comminicator.
"We need to be astronomically prepared." lol
Becky is great, more Becky please!
She's got a very positive attitude, yes. Note how she talks about watching paint dry and getting excited to wait for a signal that may need a processing time of 10.000 years forward and 10.000 back
i like that she's smart and pretty and doesn't use the word "like"
@@--Valek-- yeah because she's is not a stuck up American
As Arthur C Clarke said “either the universe is teeming with life or we are completely alone, both are equally terrifying”.
She's baaack. Becky Becky Becky !!
She's the Star :D
Been following news on James Web ever since I learnt about it some 4 years or so. I try not to think about it too much because I feel like failure at any point before it starts sending down scientific data will be so much of a heartbreak. I can't say what it's like for the scientists, etc even more directly involved.
I hope it all works out and scrapes even more detail about our wonderful universe. Thank you sixty symbols for these videos!
By far the most exciting space exploration project of the next 5 years.
Mars 2020 maybe? :D
More like 25 years
We're in 2019 and they still keep postponing the launch...
Well, I've got bad news for you. We're well into 2020 and the launch is still delayed.
Feb 2021 still not launched 🤷♂️
I've been waiting so long for this.
I'm so glad it's still going.
Regarding the 20 thousand year wait period for a return signal, keep in mind that both sides could continuously keep transmitting new information. So we could actually get a lot of information transmitted back and forth, rather than just getting to send one brief message every 20 thousand years.
Eh, but assuming we were the first to initiate, it would take a minimum of 20,000 years for us to get that constant flow of info.
This proves something more: people that believes in telepathy and stuff could make a demonstration that their methods work. They say ''thoughts are quicker than light''.
So, prove it?
"Regarding the 20 thousand year wait period" I honestly thought you were talking about the wait for the launch of the JWST
My favourite sixty symbols person. Actually you're tied with merrifield and Copeland.
I couldn't handle the stress of launching something like that. o_O
I love how Dr Berky explain James Web's functionality... Looking forward to the first images.
Brady, thank you for the recent sixty symbols videos. I've been missing them recently.
Dr. Smethurst. Thank you for simplifying and explaining. Truly fascinating!
I've been looking forward to this thing for so many years. I'm going to be so excited when it finally comes on line.
I love seeing engaged, educated and passionate talk about scientific discovery. This is how to communicate the importance of science to the public. I wish there was more of this optimism in everyday media!
I'm absolutely fascinated by these videos from Sixty Symbols. Thank you so very much!!
Now that we've gotten as good with adaptive optics as we are, I'm just as excited for the new European Extremely Large Telescope under construction in Chile. I hope the JWST becomes the icon that Hubble presently is, but the view and purpose for looking in deep infrared is harder for most people to grasp intuitively.
This was really interesting, thanks Brady
its a man
This womans fantastic. Explains everthing really well . Thankyou.
So excited!!!!!
April 2020, and JWST is still on Earth.
🤞🏽🤞🏽🤞🏽🤞🏽I pray to the science gods that Webb reaches space 🚀 without a hitch and sees like a dream 🤞🏽🤞🏽🤞🏽🤞🏽
Me too.....oh so much do I.
4:06 Comparing the list of "What might go wrong?" of any project to the list of "What happened here that might've not elsewhere for us to get to this point?" is the only way I manage to calm myself and stop stressing about that kind of thing 😅.
Becky is brilliant! Intelligent, Engaging and presents what are complex topics in an approachable manner! Bravo!
Excellent explanation about this new telescope. I look forward to seeing it launch. Love The videos guys, keep em coming!
Oh and Yes Becky I love the spark in your eyes when talk astro stuff.
Great, interesting and very clear video about the JWST! Thanks. And Becky is a really great acquisition.
Wow, never thought that Sixty Symbols would do a vid about JWSS. I AM SO EXCITED to see the first pictures.
I'm really hype about this. We have hearing about it for decades, I can't wait for it to happens.
The James Webb telescope is the space event of my life time. Nothing that has happened in space in the past few decades compares to what this will allow is to see and learn.
Really well explained. Bravo !
Seeing this from the future is stunning. All the comments hoping that it would go well when I'd never heard of JWST, and now I have the privilege of looking at the insanely beautiful images and science produced from the data it's provided... feels like time travel in a way
Dr. Smethurst, finally 2018 arrives and we count down to the launch! Thanks for inspiring the public and next generation of scientists!
Excelente Video ya tengo aclarada algunas dudas que tenia! Muchas Gracias :)
Wow, 3:50 really gives a good sense of the scale of that thing!
It`s HUUUUUUGE
Great explanation, keep them coming!
I saw it last month with the sun shade fully deployed. It was awesome.
The Galileo space probe failed to fully display its main antenna because the mission was delayed several years and the probe's mechanisms got stuck partially. The James Webb Space Telescope instead has been tested quite many times, so I don't worry about its effectiveness in space.
I've been on the edge of my seat for five years now (since I first learned about it).
Between the end of 2018 to early 2019 will be nerve wrecking for me.
Let's not forget that the larger the primary mirror the finer the details that can be resolved when the diffraction limit is reached, although with how far ground based telescopes have come (adaptive optics, lucky imaging, etc.) that may be somewhat less important, but if be willing to say still important enough to mention.
now we're getting amazing images from it :D
Very excited for JWST.
how many parts have to move in the proper order for this to work and at what point does it start its transformation
Your brightness will never dip!
It could look for Dyson Spheres (as revealed by their infrared emissions) and, along the same lines, it could also look at the Great Void to see if it is a Kardashev 3 civilization.
To think we're now getting images from this telescope! Ahhh science and progress is a wonderful thing.
Nothing can detract from your brightness Dr Smethurst ;D
its exciting to hear about that kind of ambition. gives me hope for the future in spite of all the other stuff going on.
: like a really good put" . Brady really has gotten very good at making great analogies on the fly!
Thanks Brady and Dr. Becky.
The planetary atmosphere absorption spectroscopy is incredible
This is what I'm most excited for!
I saw this and was, like, is that the Ogden fellowship person? Thanks Dr. Smethurst, what a wonderful video! (Also cant wait for the first Webb images).Multiple squees!=8)-DX
Great content my friend ❤️
excited! beyond hubble scale!
I think when it gets turned on all its gonna see is a warm glow of infra-red any direction they look at. Especially at the furthest distances Webb can see.
Do gravitational wave affect the image on space telescopes?
Was Hubble doing a "long exposure" when the recent gravitational waves were detected?
Gravitational waves don't measurably effect telescope imagery - gravitational wavelengths are going to be in the range of 100km to 10,000km from peak to peak & we don't have 'gravity telescopes' that are sensitive enough yet, but we will one day. Very strong gravity wells 'bend' light, but that's a different subject somewhat...
*Auto like crew coming through* cause I'm already super hyped about James Webb Tele and seen quite a few vids, but Sixty Symbols is boss and know this will be fire.
Really hoping this beauty launches smoothly and gathers Great data
I really really enjoyed watching you describe everything so naturally and truthfully. thank you you're a star in their own right
How can the mirrors and sensitive instruments remain clean enough to remain operational in the harshness of space? Will they need some sort of service drone(s) to maintain it eventually?
Never stop making videos!
I cannot wait to see the space satellite technology we have in twenty years.
Will James Webb Telescope counts how many galaxies in the universes after its launch & destination in 2019?
agreed the launch willl be nerve wracking! Just cannot wait until we start to see images and get some data. highlight of the next few years.
You rock Dr. Becky!!! ♥️
07:57 That blew my mind...!
I'm really excited for the James Webb Space Telescope, I am currently making a video on it right now :D
Cool channel ++++-
subscribed 👍
AstroFocus *SUBSCRIBED*
Man, you have great future coming with your channel
AstroFocus please make it long
I'm so excited for this telescope! :-)
We have the same favourite Hubble image (along with I suspect a large number of people). I use it as my desktop background. :)
I'm so excited but SO SO nervous about this launch.
You're the best Brady ..keep do'n the shit you do..
enthralling.
I was wondering why it was taking them so long to get that thing up there. But this explains it very nicely.
So psyched for the James Webb Telescope. Here's to hoping it doesn't blow up on the way there, and everything goes according to plan!
The Launch of Webb is now history guys!
Hopefully everything will be alright in the next 6 months of deployment and cooling.
MOAR BECKY
can you make a video about the asteroid belt?
9:22 I'd forgotten about all the launch delays for the JWST. It's not planned to launch until March 2021 at the earliest now.
I've been hearing about this telescope ever since I was a kid.
Beautiful
Excited about the launch in 2018 ^^
lol
But when we launched hubble, weren't there a bunch of issues with it like the images coming back blurry? If we send this one out to the L2 point, we won't be able to send people to go fix it this time.
don't see enough of becky!
Absolutely gorgeous machine
2020 and we still waiting for it to launch
This video made me subscribe
Unrelated question , but is it possible for there to just to be a quark by it self. For example could we observe on up quark? If not, why not?
We can't directly observe anything smaller then the width of wavelength of visible light, which I believe is slightly bigger then the biggest atom.
Anything smaller can't be observed because visible light just passes straight through
No, it is not thought to be possible for a quark to be isolated below a certain temperature called the Hagedorn temperature. The reasons have to do with the nature of the strong nuclear interaction. It is a phenomenon called color confinement.
4 years later and still waiting... here's hoping to 2022 :(
actually the Lagrange point you describe involves a multi-body system calculation - even though the satellite mass can be assumed to be negligible
Like beautiful origami... so, how do we get out to the L2 point to unstick everything that hangs without a space plane fleet?
So when the Web gets to L2, how long of time does it take to get the recovery information in space time and convert it to our time..
So if something did go wrong, will the instrument be too far away to fix? Is it a one-shot pass or fail scenario?
I’d really like to see what this thing can do before my time is up.
I was cringing at every single thing she said could go wrong, but then I think back to the Mars curiosity landing and how much more complicated that was. I have faith!!!
soooo cool!
I'm so excited! All the cool knowledge that'll come from this!... If it doesn't get butchered along the way!
This will change our view of the Universe!!!
And were still waiting 4 years later.
