human kind has embarked on another space adventure taught it up. one of the most sophisticated technological systems ever created on earth is on its way to make history. and to look back in it. the gems wave space telescope is the largest and most powerful space observatory to be launched into space and with a price tag of $10000000000.00. it's one of the most expansive after nearly 3 decades in the making and now on a closely watched voyage of 1500000 kilometers. scientists are hoping it will allow them to look at regions of space never seen before. once it reaches its destination, the telescope will look back in time by capturing infrared light from the early universe. that will allow us to examine the creation of stars and galaxies. and maybe i'll lock new clues about our existence. a launch is off the order,
3:35 am
80 percent of the rescue in a, in a. and i would say going off by our analysis by, by, by, by various ways of assessing that i hear it may be 20 percent off the risk of the mission. perhaps 30. i don't know, and so basically a bodies ahead we have retired a number quite some risk, but what is ahead remains are risks that we're going to take down step by step. i'm very happy that the on 5 was performing extremely well, which also means that there's a lot of time ahead for good science because so good. all the injection allows to have more fuel on board of the space cost i and 5. and i and space efficacy, the 4th is mission all to bomb it tells of sight. excellent. again, bethany scheduled will begin discussion in a moment. but 1st, let's take a look at some of the most significant moments in human kinds class to explore space. sputnik one was the 1st set life successfully launched into space. it went
3:36 am
up of the height of the space race between the us and then soviet union. during the cold war, soviet cosmonaut eureka gary and became the 1st human to travel into space and return safely after completing a full orbit of our planet earth. the moon landing was one of the most all inspiring events of the 20th century. astronaut neil armstrong and buzz, aldrin beach the moon and walked on the surface. in 1969, 20 years later, the hubble space telescope was lost. it allowed scientists to discover moons, planets, and galaxies never seen before. in 2004 space ship, one became the 1st private crude space craft, to cross the boundary of space above earth that made south african pilot, mike melville, the 1st commercial astronaut. ah,
3:37 am
let's bring in our guests in boston. are the love is professor of science at harvard university and author of excellent to rest hill in bristol, elizabeth pierson is an astrophysicist and space journalist in london, francisco diego senior research fellow in the department of physics and astronomy at the university college london. welcome to the program. either. this has been characterized as the most ambitious astronomy mission of nasa. why, why, why that characterization in particular? well, for several reasons. one is that the, the telescope will be in de la grunge point to, which is a one and a half 1000000 kilometers away from earth. it's about $3000.00 times farther than the hubbard's space that has got, isn't, service is not an option. so it's very ambitious for us to send the equipment thus far and hope that it will work perfectly as it did so far. the 2nd is that this
3:38 am
telescope, it will take the deepest images of the universe piercing back in time to when the universe was only hundreds of millions of years. all that's when the 1st stars were made, the 1st galaxies, and we have a chance of getting the scientific version of the story of genesis lead there be lies of that reason. manson by avi, which is basically that need that quest. that humanity is thought as quite some time ago to understand how the universe begin. yeah, there is definitely, you know, i've been reporting on space in space science over decades now. and one thing that you've learned in that time is people absolutely have this. it's sort of inherent, need to understand what's going on with this universe around us. and you know, whether people do that with like religion or science or some combination of the 2.
3:39 am
but it's, it's definitely one of those things as of whenever you, you get these big missions ultimately the, the question comes down to like, why do people put on these missions? and it's just that the fundamental human need to know what's out there and to understand what web is going to be really good tool tool box. being able to do that from because it will be able to look at these parts of the cosmos and these parts of the universe that we've never been able to see before because that's been shrouded in dusk. that's what infrared is so good at it through passing through that veil of death. that you find, you know, throughout the entire universe that you can look right back to the beginning of time or the surrounding stalls as they grow in or planets of things. and so i think web is really going to help us get to grips with those, those big questions. on 3 most big question, francisco is it because operates in, in for that the chances are really high that it would be able to capture the images
3:40 am
of the galaxy of the, of the 1st load after the big band, which is going to be an uncharted territory. or perhaps a turn and point for us or physicists. the, the james w telescope costume to fill a gap in the what we call the electromagnetic spectrum. they hubble space telescope piece of serving the visible part of the spectrum on a little bit of the near infrared. and then the james w is one to offset from the nearing progress to the middle infrared, which is important when the, which is neglect, seem of sort of before going not to these level. and then of course, we have the herschel, the casual observatory that was working a few years ago, or sort of in the fighting progress, which is also very interesting. it was a very successful telescope, also launched point in the library to point with a middle of 3 and a half meters. it was quite a big telescope, almost does because these one. but yes,
3:41 am
it is very important to serving this part of the, of the spectrum to locate, as you said, the very, the very 1st stars that emerged from the dark gauge of the universe, a few 100000000 years after the big bomb. we have the stars emerging on the 1st kind of building blocks of galaxy sort of brutal galaxies that are going to merge together. we still don't know how this process took place, and this is where the, the information is going to be very useful. lady angela from what you're saying from expressions of your faces. this is quite an incredibly exciting moment, but just for someone like myself or want to understand that you have to put something like 10000000000 dollars into this sophisticated design. this is my question to you are the and then you still have to wait for 6 months for the telescope to unfurl and then for the mirrors to spread. if that doesn't work, it's total failure. well, yes, any challenging task is also a risk,
3:42 am
but it's definitely worth it than the time that we are waiting is much shorter than the age of the universe. ah, the reason that we want to look at in the infrared is that if, even if you take the sun and place it very far away at the edge of the universe, there are the ation that will be stretched and the wavelengths will be stretched to the infrared such that the visible light that we see close to the sun will become infrared light as the result of the expansion of the universe. and the, in fact, the 1st stars and i've been working on the sick frontier for 3 decades are old to textbooks. the 1st stars are expected to be even brighter in that were tra, violet than the sun is they are expected to be very massive. and then despite this, what we see would be in the infrared because of the expansion of the universe. and the james web space telescope can tell us what our ancestors were. what are these building blocks that were formed 1st and lead to the production of heavy elements
3:43 am
that we are made off? so in a way, it's our origins that we are uncovering and it's worth every penny to figure out where we came from. and it's of the, the task of it will be in an all bits, which is not the same one as ha, but he's going to be behind the earth in l 2, which is about 1500000000 kilometers from the earth. which means that if there is any glitch, there is absolutely no way you would be able to send any rescue mission mission that what's the rational, what's the rationale behind this particular think put in it on l to when, you know this is one of the most expansive a telescopes created by, designed by the, by that, by that nice and other groups. and then there is no rescue mission. well, to be honest, even if it was closer to us at the moment, there's no rescue mission. when that was helpful. there was the space shuttle for a professional and that was what went in to get those services. we don't have those anymore. so even if there was something wrong with hubble,
3:44 am
you'd have to build an entire spacecraft to go would be able to, to deal with it. and if you're going to have to do was over it, you might as well do a 1000000 miles away. it's the same thing, but that there are a lot of really good reasons why you want to be at l 2. 1 is because it's gravitational stable points. that means as you go around with your follow, basically driving you along in time would be that it's always going to keep pace with us, which make communication much, much easier. it also means that it's going to be able to operate 24 hours a day at the moment hubble because it's going an orbit around the us. it can only actually observe when it's not pointing from when it's on the other side of the earth. so half of its time it can observe, i don't know about you, but if i'm spending $10000000000.00 on the telescope, i want to be able to observe 24 hours a day. and finally, it's also very, very firmly stable over back. so as hubble goes from night to date night today,
3:45 am
it's cooling up and warning down and going back and forth between those 2 temperature things which are very slightly deforms the mirror. and on something like hubble, because it's only got it only got a 2 and a half meter mirror. you can't really notice that well, with it's 6.5 meter mirror, that would make a huge difference and you'd be having a slightly blurred image. so it definitely is worth, it's a bit more of a risk going all of the way to l 2, but people have been spending a long, long, long time, making sure that everything is going to go to plan. and that's one of the reasons why it cost so much is because they know it cocktails, so they ensure they can francisco, if hobble was quite instrumental in shape in our understanding of the expansion of the universe. black holes. could jim swab be quite instrumental in our understanding of how the universe started?
3:46 am
about 13700000000 years ago, if that's the most accurate estimate, yet to be proven by tips web. yes sir. 13 point date, i think, but yes, i think you're, you're right. they compliment each other. in fact, it was saved many times that the james, where he's going to replace hobble and he's not, they will be working together at the same time for several years. and in fact, it's probably that the james, where he's going to run out of fuel because he has a fuel hydrazine that is going to help to bind the telescope in different directions during the several years of operation. as soon as you run out of that fuel, it will be or how to population. the whole space telescope doesn't have that limitation equal will continue. so probably the whole spaced out of school with out live the, the james webb. but both would work in coordination and that well will be a fantastic opportunity for science because there won't continue to cover the whole
3:47 am
spectrum all the way from $425.00 microns or so. are they the it is going to look deeper into space towards the edge of time, but at the same time, which will, it will take opportunity to look into our own solar system and look for building blocks of life somewhere in this massive expanse of the universe this, this looks like a mammoth task never undertaken before by humanity. right, so this telescope, they, we be able, for example, to look at the atmospheres of planets as they transit their stars. they passing front of the star and the some of the light from the star would pass through their atmosphere and we can diagnose that light. then they figure out if there is any fingerprint of molecules that we recognize such as c o 2 ah, water h 20 and their method is c h 4. and. ringback by that perhaps find
3:48 am
evidence for molecules that are indicative of life. i should say i took part there . i was very fortunate to serve on the 1st advisory committee that designed the james web space that has got back in 1996 and back then it was called the next generation space telescope and g esteem. and it took a long time, a quarter of a century for it to come to fruition. and there really the, the most exciting part is yet to come, may have what we will find. will we find evidence for life elsewhere? we find it how the stars were made, the 1st stars, and by the way, i wrote 2 text books about that. and obviously he wanted the forecast to be true. the predictions that we made to be true, but if they turn out to be wrong, that would be even more exciting cuz we learned something new. elizabeth for us on fall vila as space. and the universe makes sense only when we have a tangible look at things like spiral galaxies, planets and stars,
3:49 am
which makes sense to us now, because this is going to be extraordinary, the says that he's aiming to look for light, about 250000000 years, right? after the big bang, so in terms of images which are going to be sent back from james webb all the way to was nasa. what are we expecting to see here? make it easy. i make it, make it easy for us, for the hundreds of millions of people all over the world. wally, looking forward to see what happens in 6 months from now. you do actually make a really good point. and i think napa has a policy that all of the planetary prob, have to have a camera on because they realize just how important it is to be able to show the pictures to the waiting public. people want to, to see a be able to connect that set the streams web space telescope is going to be looking in the infrared, which isn't the wavelength that we can see with our own eyes. so it's not going to
3:50 am
be a picture that you might recognise, normally when you're looking i galaxies, i probably will look quite unusual. exactly what they look at depends on how people are going to set them up. because all of these images are what's called false color image. so you take a wavelength that you can't see. and the sewing a color that you can see. and then you put all of these together and they create this beautiful color images. and i'm sure that will be a lot of people at nasa making sure that well and other distributions around the world. because this is an open instrument to the entire community. lots of people are going to be using the information from it, but they will be making sure that these pictures are you know, understandable. because again, we are human and human process colors and things that we can understand. images are one of the easiest ways for us to process data. you know, as a scientist, that's the reason why, you know, you plot everything on
3:51 am
a graph rather than putting it on the table. and pictures are not easy to understand. so yes, there will be a lot of people making sure that you and everybody else in the world has some pictures already help understand. okay, what's going on francisco way of putting massive investments here, which takes decades of time to try to put into a practice. is it because we want to understand the very structure of the universe? it's just because we as humans, mortal, we're still grappling with the need to understand who we are when we come from. and how did the universe thought? absolutely, we are now filled with curiosity. remember, the dentist was invented over for only 400 years ago, and then it got a little could see what we are doing today. this is absolutely amazing. i mean this telescope cannot serve from the very beginnings of the of the universe. the 1st light of the 1st start that 1st galaxies to the formation of solar systems. because
3:52 am
now we know, i mean, if newton galileo all these people, they knew their mental blandness. i mean more than 4000 blindness already discovered by this space. telescopes actually lay the couple of mission up with this plan. is that going to be explore even further? they're trying to do is a find the, as i said, he said that signatures for life, especially oxygen. when you have free oxygen in douglasville of our planet data, you nick we what cali, almost a signature for life or photosynthesis for micro your life. or this kind of thing. formation will call our system formation life itself plus examining the planets in our solar system was what i've anywhere up, at least from it. that's going to give us a broad view from the here in regards to the universe. could we compare this to the moon landing, shall we say that this is as important scientifically speaking, as the moorland in or potentially could be much more important than that? it could be a turning point. well, it all depends on what we find. the sufficient expedition and it depends on what fish we find. and i should say that even though the infrared sounds weird, ah,
3:53 am
the nearest star to the sun is proxima centauri. and it has half the surface temperature of the sun, roughly 3000 degrees instead of 6000 degrees. and so the midst mostly in for a light and the reason habitable planet close to it, proxima b. and if there is a civilization there that builds a space telescope, they would see the images with their own eyes because their eyes were tuned to the infrared light emitted by proxy must centauri saw. the fact that we find weird is to look at the images in the for it is simply because the sun produces mostly visible light and biological creatures selected by darwin, evolution. we have eyes that are sensitive to the light that the sun produces. but in for it is by our nearest neighbor elizabeth it theoretically speaking, if you are chasing a lie that has been traveling for 13.7 or 8000000000 years,
3:54 am
most likely, by the time we detect it, the sy itself or the galaxy is no longer there which takes us to the point where do we really have to care a lot about the notion of the edge of time when time itself remains very relative. that might be and need to reset the time itself or to go back to negativity or negative time? well, to be honest, actually, if you're looking back on 13130000000 years, which is right back to the sort of beginning of when things started said, turn on basically and start it started to shine in light that we can pick up. and some of those, i think the 1st generation of stuff, a very short lived thing for the die young, but the galaxies, but they were creating, most of those are still around. or if they're not around by themselves, they are merging with others. and if you're looking back at the beginning of those galaxies, the beginnings of the stars and galaxies,
3:55 am
but then went on to bill together to create the universe that we all living in today. that's the big go. because this time, the like takes so long to travel, you will seeing things as they existed. right when they 1st start, the 1st start started shining the 1st galaxy started coming together. and that's what's really exciting, unfortunately, looking before that. so the 1st couple of 100000 years off of the big bag. there wasn't much producing light in facts that was various phases where like, couldn't travel more than a few nanometers. and so we'll, we'll never be able to look back with telescopes, show francisco less than a minute. good. could we say ultimately that in 6 months from now, we will only say it was really worth it if we get the 1st glimpse of the most distant galaxy in the universe of the most distant,
3:56 am
far all the oldest cloud ever to be deducted, that could be the moment that would be why the interpreters as you know, what we're moving into radio on softer territory here in fines. well, absolutely, yes, absolutely. yes. we are using the technology of the top range of what we are cap ability as we speak. the telescope is crossing the order, we thought them already on the, on his way, very slowly, 911 kilometer per 2nd. i'm deploying all the same shields and everything are lining the mirrors, as we said before. and then in 6 months time, we will get this fantastic, fantastic discovery, some very positive that you will want us to clean. you will be a major milestone. the knowledge of the universe really fascinating to see how humanity is using extensive his own senses to further gaze into the heavens and look for small details, but about to make massive difference in this life of the lobe. elizabeth pierson, francesco diego have really appreciate your insight into can forward to talking to
