ah, top stories are 0. italy's president has refused a resignation of prime minister mario groggy. after one of his coalition partners refused to support a confidence vote. that he told his cabinet. he would step down after surviving the confidence vote. just coalition was thrown into crisis when the fivestar movement refused to back a bill aimed at tackling the cost of living. competence vote had become a focal point of attention. within diabetes, government adarine is in fedora, inordinately, and explain what happens next. well, it'll be interesting to see come next week, wednesday the president has asked that i get to appear in parliament and kind of give his vision for how he wants to continue and what he needs. it's not clear that he's going to come out strong and somehow try to rebuild his unity government. we
10:32 pm
have a lot of things going on in the background here. there's this rising center right movement of 2 parties for tally or brothers of italy, and the, the li, which is a long time conservative party. these parties together are leading in the polls. so if the government falls in these parties aren't seen as making them fall, they'll come out powerful. they'll be able to win. perhaps the most seats, if election were held earlier, rather than later. she like is president, go to via roger. pac sir has submitted his resignation. crowds formed outside the presidential palace when news of roger practices intention to stand down broke. he sent his letter leaving office by email. i was after fleeing to singapore, following mass protests over the country's economic crisis. as president joe biden and israeli prime minister. yeah. le pete have signed a non bonding declaration to prevent iran from acquiring nuclear weapons. why don't his release visit by and also restated the u. s. position on
10:33 pm
a 2 state solution for israel and palestine. on friday, he'll visit the occupied westbank and the russian asked rock has killed at least $22.00 people in the central ukrainian city of minutes. yet many others were injured. when miss halls hit, residential buildings and businesses president wrote uminski described the attack as an act of terrorism. a stream is next asking what mysteries of the universe fe james webb telescope will uncover 20 after that. ah ah! welcome to the stream i manage habit dean,
10:34 pm
filling in for family. okay. today examining the origins of the universe with the james web space telescope. it's the largest telescope ever sentence, a space and its mission is to observe the birthplace as of distant stars, planets, and galaxies. astronomers say it's a breakthrough for science that may answer humanities. biggest questions, including where do we come from? and are we alone to get our conversation started here is nasa astrophysicist, amber strong. for me, the most exciting aspect of this new telescope is really the breadth of science will be able to do, will be able to study objects from within our own solar system, all the way out to the most distant galaxies. ever. the very 1st galaxies that were born after the big bang and everything in space and time in between. and these 1st images that we've just released really just give us a glimpse just a hit of what's going to be possible with this incredible new telescope. i'm so excited for that year of science that we already have planned,
10:35 pm
and i have no doubt that this telescope is really going to change the way that we understand the universe and ways that we haven't even dreamed of yet. joining us to explain the significance of the j. w. s t is our panel of scientists in california . jesse christenson, a project scientists with the nasa zill planet archive. renee doyenne, a principal investigator for the web telescopes, fine guidance sensor and info red imager, known as nearest and in nova scotia. lamia mala, an observational astronomer with the dunlap institute for astronomy and astrophysics. and of course, if you want to ask a question to our panel, jump into our live you tube chat and you can be part of today's conversation. all right, so, so much to discuss, i want to start with, with the basics, kind of the emotion of this moment if you will, jessie, we built this, i say we of course i haven't done anything but we built his incredibly complex telescope. i believe it's a 100 times,
10:36 pm
at least more sensitive than it's 30 year old predecessor. why is this so exciting to what does it actually enable us to do? well, hobble has been such an amazing observatory for humanity for decades now. and there are some things where hubble has just given us a glimpse. we have a hints, we think that there's something there, and we're very excited now with data with te, we'll finally get to the answers and some of these incredible questions like, what's inside the atmosphere of these extra products we're finding how far back can we see towards the door of the universe, so it's a step we've been wanting to take for a really long time. so it's very exciting that we finally hear and the telescope is performing as well as it is. right. and on that note that it's performing as well as it is. i mean i can imagine many things could have gone wrong. renee and you know that in of itself is a celebration or something worth celebrating. you know, with that in mind, we sent that's what 1.5 kilometers or 1000000 kilometers, if i'm not mistaken. and it's sending back data and that data is digestible to you
10:37 pm
or in a, what is what is the most exciting element here? well, every, everything, i mean you've set it up. this is arguably the most complex machine that you meant the that are built. and we sent at 1500000 kilometers away. and the eyes, you mentioned, the many things could have gone wrong 1st. you know, this still was so big, so we have to fold it in a big, you know, like how big are you going to figure in the, in the, the frame your rocket and incentive 1500000 kilometers, then we have to deploy it. and i use to describe this, this 2 weeks. those are the plumbing, this 7 days of terror. well really, it was 7 days of joy because things when so smoothly. and then we had july and these 18 segments with exquisite chrissy. you know, it's on, you can imagine depression, you need to july, and these murders would work better. and yet it took several months. we, we did it and it worked so well. and one thing to understand is that the tesco is
10:38 pm
always beyond a sun. she'll always and in the, in the dark, it has to be protected from the sun and it's very cold up there. it's minus $1.33 celsius, whatever. in finite this is so cold. so we have to develop new technologies to operate his vestment at these temperatures. so it was a lot of challenge, it took 20 years. and so yeah, it's now we're opening and you eyes and this guy to answer big questions about the origin of the universe. and we alone, for the 1st time, we will have a credible machine so, so on, on those big questions just quickly and maybe we can start with you. we have in, are you to chat voluntary kid? convinced that we're not alone thing. there's no way we are alone. and i'm wondering beyond that question, not big question. what excites you as someone who's, who's already processing some of the data that's being sent from your vantage point? them, you well, we have been vain for does data for so long,
10:39 pm
and i'll just right next door to me is the entire canadian extra galactic team to city. they're going through the data, and they're just all crying out, enjoy every time be, find this little galaxies really read galaxies. and we think are, you know, might be one of the 1st of the universe, this galaxies that are full of stars, which might very well, like be our own son and might have planted that like our earth. so, you know, when you look at something like this, something that is like almost a time capsule, where you're seeing galaxies at very different distances because of this wonderful property of light, you know, coming to us at the same speed. you just cannot feel, you know, you cannot feel alone in this. but certainly i think i think many of us are excited by the prospect and we'll get to that at the end of this conversation. but before we do, if i may, renee use for gimme a jessie you said something interesting kind of comparing hubble to,
10:40 pm
to this new telescope that we're celebrating today. and there is the street by john christensen, not to be confused with someone from your family. i believe but, but at least someone who created this really powerful tool, take a look at this. i'm going to scroll down a bit. this compares essentially, this is the, the new telescope, and this is the original sort of hubble image, right. and, and this is the southern ring nebula, could you just beyond sort of the fact that this looks like something that was photo shopped. what, what does that, what is all of this that we see here? tell us that we didn't know before. right, so what we're looking at here is a planetary nebula, which astronomers are really bad at naming things. so i'll stop by saying it doesn't actually have anything to do with planets. it's a planetary nebula, it's what happens when a star like our son gets to the end of its life and starts puffing off all of its outer layers and they create is a gorgeous cloud that you see today. and the star in the middle pushes the cloud
10:41 pm
away. what we, the detail that we have with database t is going to allow us to discern much more about the physics, the actual physical mechanisms that are pushing the gas away and how the gas is behaving. gives us information about the medium that the gas is going into the, into stella medium. what happens between stars? this gives us a glimpse of this. and you know, just to hear from someone else, if we can kind of echoing some of those key points that you outlined. we have christine, turn and astronomer at the space telescope science is institute, who really highlights for us. what she believes is so groundbreaking about this moment, take a look. these 1st early release observations really give us a glimpse into how j t will transform our understanding of the universe genius. he was designed to peer back to the edge of time to see the 1st galaxies for me. and indeed, the nearer camera captured grabs 1st deep feel in just 12 and
10:42 pm
a half hours revealing a scant teeming with distant galaxies. and each galaxy has been imaging, exquisite detail revealing galaxies with warmth, bright star clusters, and there's and shrouded in dust in our newly formed understanding, goes beyond these beautiful images to include spectra that reveal precise distances to individual galaxies. what used to take couple days now takes 2 to 2 hours. and as a result, almost every observation will provide a glimpse into the district universe. so, you know, already when we say we are going to be exploring exile, planet atmosphere is in more depth now as a result of this new telescope. what does, what does that mean? i mean, some of our, you tube of commentaries, ghost in the blur thing. this is unbelievable and exciting, but when will we prove other life besides us exists? that is the big question. we also have someone named and had saying, well, the more the discoveries, the more the unanswered questions. so do we anticipate that some of the discovery
10:43 pm
is being made already or that will be made will be surprises. and that do you think this is going to really for sure, make us know that there's life out there? well, we can't know what our web will will detect life, but what we can be absolutely sure that will make jain step how is answering that question. yes, understand the when when we need to do so we're trying to detect an exultant atmosphere. we're trying to detect the molecules that's in there on, on large molecules like oxygen and that those are made by but by life and, but you know, we haven't really done that yet on small planet. we have to take that much years on gas, john planted like the one we saw, the nearest instrument take this beautiful spectrum. while you see the bumps and wiggle you get used to these things. going to see many of these spectra in the coming year. and so that's spectrum prove without any doubt that there's water and that monk use. and you can also detect methane seo. and when you combine with other site, the other side sentiment,
10:44 pm
you get the whole suites of chemical do to detect molecules. and that's absolutely key to one day. and so the question is there, you know, bias natures and gas that are due to biological activities. yesterday, the stand that hobbled view was in terms of color is what you mean like this, you know, hobbles or looking. and now where it's like, you cannot re my, my hand right completely different. and so just like the, the field, we have a completely new perspective and with exquisite detail. one big limitations about hubble is that it goes around the earth, every 95 minutes next 90 minutes. so when you try to measure a like triple meetings upon it, it's always interrupted in this case where we, we can continuously observe this object without any interruption. and that makes a big, big difference. and renee speaking there, i was showing the audience just kind of the comparison of the korean and nebula, for example. and some of those elements that you were describing. i do want to kind of kind of ask or actually let me let eric baker, he sent us
10:45 pm
a question that i'll put you in a take a listen to what eric had to say. given that the james web space telescope only see certain colors that are on the spectrum of light visible to human. how scientists go about tolerating the images that we get to see online. and i forget that our jessie sorry. sure. so what we have to do is we have to take the wavelength that james webb has base health group looking at which is in the infrared heat. and we have to map those into optical wavelengths that we can see with our eyes. so we take that, that section of the wavelength that we can't see, and we remap in, we can see. so these beautiful images are not what you would see with your eye if you were out in space looking at these nebula, you wouldn't see that. but they are giving us this rich amount of detail about the different wavelength that these objects are meeting at. and so it's not that there
10:46 pm
was no end for read before it was. it's just that much more advanced, right? if you will, like the hubble, have the capacity to a certain extent. i mean, i'm reiterating, maybe i'm wrong. i think i'm wrong. tough. tell me. no, correct. let me to. i just want to mention. so the previous grade observatory that was an infrared telescope with spitzer spits there was an after mission that operated from 2003 to 2019. and it had infrared capabilities and was able to see glimpses of again give us hints about what was there and so many interesting questions. but leave us wanting more and web is giving us more. you know, obviously we've been celebrating so far. i see that there are 2 other guests are in agreement with you nodding there, but i would be remiss to not ask about some controversy. of course, there's always controversy. we have, for example, this tweet thing, thing the images from j w as t comes with the bitter sweet knowledge that the person the observatory is named after would not have wanted me or the dozens of other queer astronomers i know involved in this incredible achievement. it deserves better using that hash tag,
10:47 pm
they are rename j w s t. a lot of people might say, well, who cares why this controversial your thoughts on this, jesse? yes, so james webb was a nasa administrator during the apollo he is and was very instrumental in having the system successful apollo emissions prior to his time at nasa. he was in leadership at the state department when the state department was going through this period of purging l g b t. people from the state department in the early fifties. and it's not clear that james webb had any specific role in that, but he was in leadership in the state department the time. and so then it comes into this, you know, what responsibility did he have to stop it? you know, was the product of his time, was he following orders when it's very unclear the extent to which he was involved in this. so there's just some murkiness and it made people, it was the shattered things a bit. it made people uncomfortable because you don't want to think that this
10:48 pm
incredible new instrument that was built for everyone named off to someone who wasn't for everyone. i understand that. so that's a great way of putting it. let me know you were going to say something. i want to add, i mean we will the james web space telescope. it's now being launched in error, which is where science is not a lot more open. and now we are a bay and available accessible people around the world in a way that maybe the hubble space telescope, or the previous missions have not have been be now have the data that was released today is actually available for anyone around the world to download and analyze the software that we are using, trying to license data is also more accessible. and i think because i don't, world post pandemic has also changed where we are now more able to connect with each other or conduct meetings. and the researchers over on by i think we are
10:49 pm
moving to an era where with the james never did, we will see people from all over the world coming in into and, and getting, you know, getting to do science with this wonderful telescope in a way that has not have happened before, but i think there's, you know, there is a lot of things to look forward to now here most, most certainly, and among them as much as i want to look for it and we should and there is so much to look forward to i want to ask you just for a little bit of context, renee, you know, hubble versus web if you will. the last time nasa launched an observatory of such kind of importance and significance. it was really deemed a disaster if i'm not mistaken. in 1090 some, you know, astronomers like sandra faber, others saying it was an absolute kind of catastrophe. why is that? and i don't want to focus too much, but, but how would you compare this moment? well, i a hubble that the, what you're referring to is one hobble was launch. he had some eyesight problem and
10:50 pm
we had said that was an issue, a mistake made which these things are not easy to do, of course. but of course we learn from, from, but it was fixed, you know, because the hubble was cool, is, is close to the the earth orbit. so we could send the shuttle and change dance meant to crack its eyesight. and then hobble came back with his good eyesight and you know it to a truly, we just live astronomy. now we learn from that, and before that we were very careful, would you use the to not repeat the same mistake and you know, there's no problem with that with the telescope. and as i said, it's the re complex machines, but it's deployment, and it's the and it's commissioning fairly smoothly. and so, you know, we should, we should be proud at one point i want to mention is, what is very significant about his project is that this is an international project . and we live in, in troubled times with wars, ukraine and his with some project where you may get together with common goals
10:51 pm
about understanding the universe. and that was quite an achievement to, to, to do this, you know, nasa, canada, and europe altogether to me just just go now for the well now everyone can use the telescope most certainly, and i, i appreciate you making that point. i also, you know, just looking at some of the numbers here, i mean, just to put this into context for us, just the, i might be wrong, but i think the university is about 13000000000 years old. and we've been around for about a 1000000 years. again, my math is horrible, but the point being with all these trillions of galaxies and just seeing those images, how they compare, what, what can you share with us about how this gives us a new kind of macro sense of where we fit into the world. and where to invest our resources in the future, a lot of people might say, why spend $10000000000.00 looking into outer space when we could be spending it here to fix our planet earth?
10:52 pm
yeah, these are really big important questions. and it's not a small amount of money, right? it's, it's a reasonable amount of money. i would say it comes back through the fact that you reference this at the start of the show. these are some of the humanities oldest questions like where do we come from? are we alone and where are we going? and the deeper we can look into the detail of the universe around us, the closer we get to the answers to the question, my can, i think a lot about what it would mean if we found life on another planet. you know, how would that change society would we all just get up in the morning and read the newspaper and the headlines would change the next day, or would it change something fundamental about how we treat the planet and how we treat each other and how we treat the universe, you know, there's a lot of talk about colonizing miles for instance. and that's it. really interesting and problematic. like are we allowed to just go and take over space that didn't always end well on earth?
10:53 pm
so we have to think really carefully about what we're doing and things like with he give us the information to make more informed decision, better decisions about what we're going to do as a species. while i was, if i go on please, rene. yeah, i just want to add that, you know, we often take for granted all we have around us, right. but what we don't appreciate is all the innovations we have. i'm has an origin. and in fact, that when you go in details, it goes back to answering basic questions. for example, give you an example. the camera that looks at me is a technology that was the device in the mid seventies. not to do a camera to do tv charles. it was equipped the hubble space telescope to, to understand the universe. and so these are true, you know, nasa funding to develop technology and now today's, this is everywhere, but just the tv. this is medical imaging. so, you know, you should think astronomers if we can use our and take a selfie this, you know,
10:54 pm
the, the, we are curious species and this is the curios at the is the deepest root of innovation. so fundamental science is fundamental to all we have around. uh, yeah, i wrote that down. curiosity is the deepest root of innovation. i feel like so much to put that on a t shirt. let me i know you want to jump in, go ahead. yeah. and just after that, the budget that's being invested in jane said that's over a period of, you know, 25 years. and, but that's only a fraction of the cost that the nation to have both built of toes could spend on military budget every year. i've seen a lot of debate about whether we should be spending more money, whether we should be investing this money in education or be, are doing this because we want to learn the right universe. then that's all coming back to that and that's it. and that's a great point. i actually want to put another question to a lot of people on youtube asking about black holes. and i know there's,
10:55 pm
there's always a conversation about that online. we have already been news. the thing how far back in time can be looked with this telescope. i know, let me know that's what you focus on. i do want to just piggyback one more question in here that was sent to us from denise laurence. take a listen and then we'll come to them. you so i'd like to know if you have images of black holes. and if you can even see a black hole. so how far back can we look and are we seeing black holes? well, we are trying to figure out how far can we live? we are trying to find, you know, the galaxies, the structures that have formed in those 1st few 100000000 years of the universe with the 1st maybe 400 meters we years right after the universe. and i guess the answer is just wait for to, we'll just have to wait to find out how far. and so that's
10:56 pm
a good look at the good answer. quick, quick poll across our panel before we go. so the telescope has, as we heard already detected water in the form of steam, you spoke about potentially methane and other gas has being detected. renee, will we detect signs of alien life for lack of a better term in the universe within 10 years? that's what some nasa scientists are saying, jessie, your vote yes or no? i don't think so. 10 years is to show it. give me 20 to 30 years and i'll say yes. all right. what about you? renee? i was going for 2 decades yet 1010 years is a bit short. is 10 years. is a bid. sorry. i'm yeah, yeah, i would say along the same line. yeah. you know what, renee and jesse say still go back, but go ahead, renee, quickly, that you know yet you allies to decays. this is very short. it means that we, our generation will see this groundbreaking discovery. and that's really the story went thing about it. so we humanity as reach technology maturity,
10:57 pm
transfer that question and that, you know, we should appreciate that it's just really amazing. and i'm not going to say that web is going to do that. and, but i said it's going to make dine step to understand the habitable d agreed. i think in 5 you will say ok, here's our planet. we know there's water in the, in its atmosphere and this all molecules and the looks like this maybe habitable. well, that's the place to look at. and this will probably have an emissions order of b tells come on the ground to a look at the system. this is where web will make it will then have major discovery . and then just to clarify, you know, we've discovered water and oxygen, or am i wrong about that? jesse oxygen i to, i'm not sure about molecular. okay. we have seen water. we have seen methane, we have seen carbon dioxide and carbon monoxide only seen sodium. i don't know about oxygen. i don't know what the command whitley. ok we haven't. we have that
10:58 pm
very. i don't know i'm, i'm pretending i know what concoction of things need to be found to determine that there is live out there now. i'm joking. but certainly a topic that really opens and expands the mind, even if it's hard to wrap your mind around this discovery and all the discovery discoveries that lay ahead. thank you so much. jesse renee and i'm yeah, that's all the time we have here at the stream for today. thanks for watching and see you next time. ah ah
10:59 pm
how and why did it become so obsessed? with this law, we were giving them a tool to hold corrupt individuals and human rights abusers accountable. they're gonna rip this deal apart if they take the white house of 2025. what is the world hearing what we're talking about by american today? your weekly take on us politics and society. that's the bottom line. ah ah.
