Hey Fraiser. You being able to produce 1 hour videos on this topic, without having to dumb it down to for the advertising people, and making a living off it to be able to do it full time, is an incredible beautiful thing and represents the best of what the internet can offer us 2024. Thank you. Thank you. Thank you.
Ae you kidding yourself. Its as shale as egg's shale. Fraser, reinvente yourself, for 25-50%, u need it to become bigger. For example, give a practical tip for astronomours , at the end of episode behind titling. Like how do i set my scope, o how do get the view of this month.. etc! (!). Yes, u have (some) succes, but pple log out, and i think because above. Or make some new show-opening, ask 1-2 questions to person interviewed, and when 1 fault dont dpo interview. pple will remember somethin like that. I found you, thats a sign.
What a great interview! Not just the headline content, but also the discussion of scientific priorities and constraints - great insight into the community!
can everyone plx report the TMme scammer in its channel for impersonating. Only this makes RU-vid act. Have Fraser's channel URL on hand. You will be asked for it.
Fascinating conversation. This dialogue addresses what I've been wondering as to why there has been no new published papers on the system's other planets for a while now. It's also interesting to hear the larger roadmap and what's been happening behind the scenes. Lots of variables I haven't thought of taken into account and tested being explained in digestible terms too.
Your interviews are outstanding. Great guests, smart questions, fascinating insights with what is going on in the science of exploration, and an audience that hungry to hear all about it. Thanks
An English quirk. Habitability and inhabitability are like flammable and inflammable. A habitable place can be inhabited, the same as a flammable object can become inflamed. For an unlivable planet the somewhat clumsy word "uninhabitable" should be used.
Thank you, Fraser to bring on one of the most interesting topics and having Professor de Wit, an exemplary academic teacher with deep knowledge, drive, and thoughtfulness about reality. Excellent talk, absolutely captivating!
Every one of your videos is an absolute gem!! I JOINED THE PATREON!! IF you read this, and you join the patreon, TELL OTHERS on this list that you joined the patreon, this will encourage others! JOIN TODAY, TELL EVERYONE TO ENCOURAGE THEM!
Excellent interview. Fraser, we couldn't ask for a better guide to discovery than yourself. You bring us along on this journey with the same passion and curiosity as the rest of us, while instilling and reinforcing the qualities required to do good science, I.e. patience, accepting a lack of clear answer or conclusion and willingness to drop prior held views in light of new evidence. Of course this all goes to the heart of science; that is that we're all trying to advance our collective understanding of the world while acknowledging our present knowledge might be partly or wholly; wrong.
Wonderful, captivating, and so thought provoking! With Hubble, we saw blackness as the background between stars; with JEST, we see radiation and GALAXIES in every image, so filtering out the background is more challenging.
Thanks for lifting us up, so we, as humanity, can join this cosmic journey (with its disruptive challenges ahead). Thanks, Fraser and Dr. De Wit. Bringing us up to speed about astrobiology helps us enjoy this journey. In a couple of decades, we might look back at this decisive moment in time when science was capable of indicating the presence of extraterrestrial biochemistry based observational evidence.
I havent seen the video yet, so this may be brought up, but there was a recent/upcoming observation of TRAPPIST-1e using a simultaneous transit of TRAPPIST-1b to get around stellar contamination. However, there were other transits of TRAPPUST-1e observed before that. Which seems to me that they have data for the TRAPPIST-1 planets, but it's very inconclusive, and we'll probably see them talking about that when the papers finally release.
Thanks again Fraser, 🤯 you hold your own with a MIT Professor and produce a fascinating interview 🧐. Thanks to Dr de Wit, he had some skilful insights to ponder upon 🔭📡👍
I think atmospheres on planets around red dwarfs are pretty much in danger of being blown away... but blow away everything, 100%, by default? That sounds a bit too much too. And the only way ever to be sure is to do the measurements. I would want to be pleasantly surprised by the presence of a thick atmosphere on one or more of those exoplanets.
CFCs in the atmosphere of an exoplanet would occur very briefly in the life of a civilization if our experience is a good guide. Even evidence of fossil fuel use and fission reactors would be rare considering the lifetime of the galaxy. Civilizations with which we can identify are unlikely to overlap us in the flow of time.
That's true! Maybe, as the likes of Adam Frank have suggested, we should look for signs of 'polluting industry' not on pristine worlds but on their inhospitable moons, the 'service worlds' where intelligent life might choose to home its actively polluting industry.
Regarding your point about civilisations being unlikely to overlap in time, I think that's a huge part in any Fermi Paradox consideration - that of distance, not just the familiar notion of distance but distance as in separation in time between observer X and civilisation Y. Man I wish light wasn't so slow. 😅
Thank you FC for this discussion. Thank you for the very good questions you presented. And thank you to de Wit for providing very informative answers. This is how science is disseminated.
Fraser I have been watching and listening to you for a long time, and I truly believe you have reached a level of mastery in science interviewing that can only be a result of a pursuit of your passion, hard work, and a dedication to your craft.
Red Dwarf Stars are very active in early life and can blast away planetary atmospheres. But these stars have very long lifetimes. After they have calmed down the planets can be struck by comets, asteroids, etc. They may have vulcanism. Can these planets have atmospheres re-introduced over the long lives of these systems/ If not, why not?
Have we ever been told how old/young that solar system is? If there is actually life there, and evolution etc are a universal principle and the "speed" of the evolution is approximately the same as on earth, how far ahead or behind the earth is what we will find there? Approximately of course
@@CybAtSteam - anyhow, if we find life there and they are ~4 billion years ahead of us we can kind of conclude we never will have warp technology, and probably not Dyson spheres either
@@doncarlodivargas5497 You won't be able to tell how old that civilization is through this though. If you spot one, it doesn't immediately mean, that they're 4 billion years ahead of us. We can not tell, how long this life is in existence at all. There are many additional factors to consider. For example the amount of or addition of extinction events. This civilization could still be younger than ours, if their predecessors just vanished recently. If you apply this idea to an fictional observation of Earth from afar, you would conclude, that dinosaurs are living on Earth and that they're already for 65 million years in existence. And we all know, that this isn't the case.
@@dnocturn84 - of course, but it do not support the very popular idea about a universe filled with advanced alien civilizations swishing around in space with their UFO's
Seems to me that the move towards production line rocketry needs to be extended to science hardware. We have always built one off telescopes. Maybe we should look at the cost reductions and increases in science achieved by building multiples a telescope design. Also wonder about the feasibility of a earth,/moon l2,l4,l5 interferometer.
He doesn't seem very happy and confident about the results he can't talk about:( Thank you for your candidness and for coming on the show today, Dr de Wit!
Very interesting. I think he may have meant that with a flare you get a unique opportunity to get more light on a subject from a much wider angle but it will be overexposed because you aren't ready to read it. So he is saying they are developing ways to take advantage of that instead of it just going to waste or being like an airplane in the shot. That is pretty amazing in of itself, they are figuring out different ways of studying the subject and getting ways to read it, and things really look bright. He also looks like they have been under tremendous pressure from their bosses, who are pressured by investors or whomever. I bet that is a hard job.
So how many red dwarf systems can we make definitive statements about what planets (if any) they have? A large enough sample would give evidence of how unique Trappist 1 is. Is it just a problem of finding systems with usable distance/angle combinations? Or is it truly an outlier?
There are many red dwarf systems out there, where we do know that there is a planet or that there are multiple planets. But only Trappist-1 has the optimal orientation of its orbital lane, so that we could observe its planets and especially all of them right now. Trappist-1 has additional features that make it such a good observation target too. It's distance, relative to our observation capabilities, it's position - not being in a too dense region or against the orbital plane of the Milkey Way, etc.
11:42 For the embargo lingers, but he said he's sure we'll hear about it in the coming months. That's better than in the coming years... or no hint at all. Looking forward to it.
Can anyone explain the notion of an embargo in the context discussed here? Are we talking an embargo on a published paper, on a research team's findings, or on access to an observational instrument or something?
Wow. This talk should be a go to for anyone who wants to start learning about stellar spectroscopy. Doctor De Wit explains it so very well. The French/Belgian "Je ne sais quoi" infused in an engineering mind is a bonus😉 TBH I have very little hope for the trappist system. Next to the fact that these M-dwarfs are pretty violent for a significant period of time, there is also the problem of these planets being eyeballplanets. There's a lot of potential energy between the day and nightside. I can imagine that also being a mechanism that sifens of the atmosphere at the central area of the eyeball.
It such a insightful interview. I am a novice in cosmology or whatnot. However, that time when science found Trappist 1, had got me fire up. Then it went quiet..... almost silence. I understand it takes time to study. Dr. Julien De Wit is so honest what is happening studying Trappist 1. I"m surprise that I felt the anti-climax somewhat.
On stellar contamination, would it be a fair analogy to say it's like smelling two different things in the same room and that you're just trying to figure out which one you're smelling more? Apologies for inflicting that comparison on the reader. Just trying to understand the issue.
I never get used to how much humans can know.. although this kind of science is not really practical for every day life I find it compelling and of great interest.. I really am not a party pooper
"100 transits would be give or take 500 hours"... actually, if we include all 7 planets, we have almost exactly 1687 transits (in front of the star) in 23424 hours, that's about 13.885 hours per transit on average. But perhaps he in including transits behind the star, so that would take 694.25 hours for 100 transits on average.
I think it may just be the only thing that will get humanity to all (well, the majority) start working together, to end wars and country boarders. It may be the thing that saves us, bringing us together for a common goal. Well, it would have to be an alien threat to actually do that, a real world war...oh we are doomed either way.
Rather than using a coronagraph, could you take a picture and then use that data to digitally turn the pixels that show starlight off on a subsequent picture?
If M dwarf (red dwarf) flares are really bad for the planets closer in could they also actually be good for the planets further out making them warmer and more habitable due to the extra heat and energy they provide? Any studies, work, modelling done on that? How could an ecology and different lifeforms in it develop if they had to rely on occassional irregular but very high intensity spikes of energy, heat, light, radiation followed by prolonged periods of very low energy levels - very irregular extreme feast or famine conditions?
Plants on earth need a combination of red and blue light. E=mc. Energy equals Acceleration. Low energy levels = slower plant growth. Plants are annual or perennial. They reproduce in one cycle and die. Others will go dormant over winter and start a new growth cycle. Trees and plants that bud out early can be killed by a late frost. Flares are random and can't be a part of the plant cycle. There are 6 million species of insects on the plants. The plants convert sunlight into plant matter, and the insects consume the plants. Don't expect complex life forms. There is not enough energy to accelerate biological processes to intelligent life forms. Plus, the randomness of the energy. Cicadas have a multi year life cycle. Hibernate for 17 years, consuming energy from tree roots. Then, emerge and create the next generation. Possible for there to be life. Not probable, though.
We already know that the first planets atmosphere results have been shared and obviously we all knew it was too close to be able to host life.. now im sure the second one wont be able to eother and then the outer one too cold but the inner 3 i am curious about and wish they would tell us already.
Maybe they should send a small telescope at the edge of the solar system looking at the inner solar system. And then making observations un ordre to get better models on stellar dynamics.
This interview answers fermi’s paradox. We simple are incapable technologically of finding worlds the size of Earth with similar transient properties and around a similar star. That’s why we can’t find any habitable worlds and only keep finding hot Jupiters and planet systems packed within mercury orbit. I never understood why no one is willing to acknowledge this reality.
Just the fact flares and a magnitude of regular m stars lifespans is so bad and good news that we clearly will need years still to find even atmospheres in Trappist 1
I'm guessing the doctor Frasier Crane jokes have likely gone stale... Lol. Great video, thanks for sharing. All joking aside, isn't this theoretically possible, plausible, and infact the most likely scenario, to describe the present state of our solar system??? This is from the enuma Elish Scholars compare it to the Book of Genesis and admit it is describing the formation of our solar system. The Enuma elish was sung aloud every spring equinox celebration, all across ancient Mesopotamia, for around 3,000 consecutive years, and over the rise and fall of three great biblical civilizations Sumer, Akkad, and Babylon itself. This is Part of the knowledge originally passed from God to Enoch, then on through Noah and his sons, who founded these very civilizations, where it was told and retold and celebrated for so very long. The Enuma elish also answers every anomaly in our solar system that modern planetary scientists struggle to explain, like why the Moon is so big and so close to the Earth, why the Earth has way more water than they calculated should, why the planet Venus rotates backwards on its axis, why the planet Uranus rotates on its side, why the asteroid belt exist, and why Pluto transverse the orbit of Neptune, to name a few. Planet nine as they call it, has already been mathematically discovered, in much the same way we first discovered planet Neptune. It's real name is planet Nibiru, and it could possibly devastate the Earth on its next crossing, approximately a thousand years from now. It seems to me this theory from the ancient texts, of our very first civilization, deserve the scrutiny of modern scientist and should be looked at through the academic eye. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xW0ER-DtW_o.htmlsi=RAB-lSs3Yuwgtoh6
This is very true. Considering how expensive JWST was to develop and build, it would make a lot of sense to build an entire fleet of them - however big that fleet might be in the end. Especially the development costs would spread over multiple units and production cost sure would also reduce with each additional unit. Doesn't have to be paid by NASA entirely - its partners could also invest in this programm. It's a shame...
If insects would have evolved into more intelligent beings and not the apes, there probably wouldn't even be curiosity for space travel. I can't shake the feeling that what we are looking for in space is really the security of not being all alone and thus all responsible.
Wait a minute. I'm not an astrophysicist, but I do have a pretty sensitive "blowing smoke" detector. Wasn't there a much more clear and simple way to answer the "When" TRAPPIST atmosphere question? Like- "Oh yes, we need 500 hours of JWST time just to fully analyze one planet atmosphere, and we have 4 to do. Now, we only get 2% of the time, so do the math..." Something like that. And BTW, no offense to Dr. de Wit, but is it just me or does his skin look more like some kind of hyper-advanced polymer? I'm asking for the "aliens among us" community.
