I am truly grateful for such gifted science communicators. Thank you for a gripping talk and for an audience with intelligent and focussed questions. I was not so far off the pace in my understanding but now I know more about where the holes are in our data gathering abilities and what is planned to overcome them. Thank you.
It needs a lot of enthusiasm in order to cover the non-sense she says, for the novice audience. I mean one has to be more humble when she's building the whole argument on spurious shadows.
What an ignorant comment. You have pure ignorance. Pure ignorance is when one doesn’t understand the data or concepts, and instead of educating yourself, you just dismiss it.
True. Problem is we have too many people that fear knowledge. Hopefully we outgrow that before we destroy ourselves. Then MAYBE.. just maybe we can make it to interstellar exploration.
A fabulous speaker talking on a fabulous subject to a room full of magnificent astronomy nerds. I loved this, especially as I'm a Queenslander like this young lady.
Interesting question after the talk regarding the probability of transit, which revealed that only 1 in 200 stars and their associated planets are sufficiently aligned with us to allow detection of an earth-like planet. So as yet, we’re only able to observe a tiny fraction of the planetary systems out there.
I love it. Kepler has studied 200,000 stars in the Milky Way and found no Earth like planets. Yet Christiansen can postulate that Earthlike planets are common in the Universe. We haven't found any yet but we can be confident that they are plentiful. That is a pure specious claim. And I might point out that to be Earthlike we need something more than rocky planet in the habitable zone. How about a planet with a magnetic field and with tectonic plates. In fact there are probably many Earthlike characteristics that are needed in order for a planet to qualify as being truly an equivalent to the Earth.
Enjoyed JC's talk, more so for her enthusiastic, slightly offbeat delivery. The most interesting question came right at the end. We find an Earth 2.0, so what then? The answer lies in what technology is available to us at that time.
I was delighted to find this erudite video. I had recently bought all three of the Arthur Templar series for my grandson for Christmas. I have to confess I wrapped the covers of each book so that I could read them all without marking them. I loved them. I think my grandson will, too. I don’t want to give anything away about the plot, but the exoplanet Proxima Centauri figures in the trilogy. If you like a quiet read in speculative fiction, it’s a well-written trilogy and worth the time. The trilogy shares the Banner ‘Arthur Templar and the…’ The first one is The Curse of the Nibiru, The second one is The Secret Codex, and the last one is the Serpo Gambit. I enjoyed each one.
@@azharidris7092I think she uses humor very well.. keeping the audience and many (obviously not all) viewers engaged with a natural sense of humor while delivering a lecture on a technical subject.. Thankfully not "3 Stooges" slapstick and not expecting Eddie Murphy.. I wouldn't use the word "hilarious".. "Informative and entertaining".. Humor is subjective. No need to judge .. Be Well!! 😃
I fully support the search for exoplanets and hopefully living worlds. As for the naysayers that troll about our not having starships or "FTL" propulsion systems.... I have faith we humans will find the key...or loophole...for defacto FTL. AND...when we do... It will be nice to have the galaxy mapped out with potential new homes for humanity.
We can't even stop slaughtering each other? Destroying our only home. Maybe there will be a time when we can travel faster than 186,000 miles a second. In order to get to that time we must tend to our current self in inflicted catastrophes.
We can't even solve basics at moment.going backwards with 50 years social media has divided us and will destroy us.internet will be unusable within 10 year's
@@paulmurphy8549 not to mention we don't even know the habitability of those "exoplanets"... to travel thousands of lightyears and find out our calculations were wrong or that it's already inhabited by beings that DON'T WANT ILLEGAL SPACE IMMIGRANTS... LMAO
Yes we have other issues now. We also did back in the late 60's early 70's and still landed the moon several times with primitive tech compared to what we have now. We can walk and chew gum. The thing is IF we make it that far into the future where we figure out physics breaking FTL it would seem reasonable to assume we would be over nonsense like wars and religion and the entire world will be on the same team of good and advancement if not for anything then protect/prolong our species instead of greed/ dog eat dog being the common goal.
Jessie, thankyou for sharing your wisdom and humour. A very interesting lecture and I'm grateful the information was delivered in a manner that was easily understood and without any pomp.
Outstanding talk, doc! What a fun surprise it was seeing you here!!! I'm so excited to hear about your first face to face meeting for the habitable worlds observatory concept coming up. I bet that's gonna be a room of _quite_ the 20 people! I mean we already know they have the queen of exoplanets, so that's a big head start right there hahaha
Knowing the planets moving harmony with each other, can you extrapolate where other planets should be with the ones that you have found in the solar system?
No. You need to find physical evidence via the orbit paths/motions of other known objects in the system. If you see deviations from the calculated motions, then you go looking.
She did well dealing with her nerves.❤.I could hear her stress. As far as finding new homes, its pointless unless we evolve into an intelligent species.
Jessie Christiansen is a very good and entertaining communicator. I found this discussion on exoplanets really interesting. It's a shame that our current telescopes aren't sensitive enough currently detect an Earth 2.0 exoplanet and was a bit puzzled that NASA hasn't made it the highest priority in the next few years. I guess NASA didn't anticipate that most stars are noiser than our sun.
Jessie, I could listen to you all day. You're such a fun but informative speaker, and your presentatin encompassed so many aspects, I was captivated. I would gladly offer my Time as your own personal audio book reading intern. Reading to you on the beach for the days that your eyes were tired. I guess if you're married, your husband can come and listen too. 😊 Maybe turn the pages LOL. Humbly OKC.
What (on Earth) do you mean lol? But let me be real with you, because it doesn't take another religious person to offer you some perspective (you can take it or leave it), although I will pass on some insight from a PhD astronomer, science communicator, and devout Catholic who personally works at the Vatican City's observatory (which happens to do most of their astronomical research these days in the desert out in Arizona because of the modern light pollution over Rome). I'm talking about Brother Guy Consolgmano, a man I respect immensely. As he will diligently explain to you, me, or anyone, there is no, and I repeat *NO* conflict between science and the church (or indeed any major religion I'm aware of). If that is your take on a scientist explaining what we've already discovered, why that knowledge suggests that there are indeed earth-like worlds out there, and how we're gearing up to look for them, then my friend, "maybe you don't know God and creation as well as you think you do", and maybe opening up your mind a little to explore creation for yourself can end up bringing you, a person of clear faith, closer to God. Science is your friend, not your enemy. It is literally the best way we have to explore the universe we were all born into no matter what our spiritual or religious preferences or backgrounds might be. There's nothing _Anti-God_ about looking up at the sky, because how could there be?! I just hope you'll think about that for a bit. Do you look up at night typically from wherever you are? Is it a habit of yours, like it is for so many of us, to just stare at and absorb the vast beauty of what sights our skies have been showing us since before even the dawn of humanity? If not, has it ever even occurred to you to try that? I'm not asking you for an answer or a reply. I just sincerely believe that there may be way more to enrich your journey that you haven't realized yet that you can actually start exploring for yourself RIGHT NOW, completely on your own.
what a wonderful video by our most smartest people and yet they are so down to earth talking and explaining what is going on and what is going to happen if technology allows us to predict before now and the future! l never seen a video so open minded and so helpful for those are just a dust of the space! (we are just the simple people going on about our lives!) l just would like to thank you for your time and afford to improve our knowledge and for trying for brighter future for mankind!
Our fastest spaceship would take over 100,000 years to reach the nearest star. Exoplanets make good after dinner conversation but there is no reason to think we will ever be able to reach any of them. Earth 2.0 has become the most boring subject since "could there be life on...?"
Yeah yeah. We can’t get there from here. Horse feathers. We will find a way. Many smarties said we’d NEVER land on the moon. Ten years later we were landing there. We will find a way. Hide and watch.
There is a growing amount of circumstantial evidence that advanced life and possibly all life is unique to this planet. A scary idea but we have never picked up so much as a radio blip from anywhere else in the universe.
@@Scandoboy1000 . I understand your position but I think it's a logical fallacy. Say we have a box and I ask you what the odds are that there is a rabbit in the box. Would you say 50/50 since there either is or isn't? Of course not because there's not enough information. Similarly there either is or isn't other advanced life in the universe. We have zero evidence that there is, so however many billions of planets there are is irrelevant. It's like saying since there are billions of cattle on our planet there must be some that are bright blue. Until we find a bright blue cow the speculation is meaningless. No matter how many billions of cattle, it's highly possible there are no bright blue ones until we actually find evidence of one.
Congratulations - I was able to keep up, no mean feat! You pitched just right! Do you have a blog I can follow? And, my sympathy - to be so enthusiastic, for so long, can be extremely wearing! I hope someone is going to support you DOWN off your post lecture High! Have a great Christmas, though do try to take time for You - we need your intellect, knowledge for as long as possible!
Drake equation has that last variable that greatly reduces the odds. I’m sure there have been many intelligent civilizations since the prior generation of stars formed. But we miss each other due to distance and time. My guess is civilizations use up their resources too quickly and lose their ability to communicate.
Personally i think this is a stupid concern. We already have earth 1.0 and we’re not doing a good job taking care of it. It’s human nature to be concern about “today” and we’ll leave it others to worry about tomorrow. It requires a couple of generations acting in cohesion to fix global warming for future generations. It requires foresight. Meanwhile you’re looking for earth 2.0, the money and especially the time it would take to get there considering the distances, it would take generations. Yes, the first pilots will die, your seeds will grow and die or be nurtured in incubators for centuries. So again, foresight is required. The same foresight we’ve shown we aren’t capable of using in unity to solve global warming now.
Amazing lecture delivered by Dr Christiansen. Just a small detail. Dr Christiansen said that Jupiter has 1% the mass of our sun but it is more like 0.1%. Jupiter is 1000 times less massive than the Sun.
A nice presentation and work. What's the point? We'll never go there unless someone develops FTL travel which seems unlikely at present. Let's work on improving life on Earth 1.0. Keep the dream alive though.
I bet there was a hominid way back in pre-history that saw the hominid that was discovering the wheel and immediately went into a stupid rage because what is the point!!?!?!?!?!?!
Perhaps there being worlds in which everything lines up to where intelligent life can evolve is rare, it still makes sense to think this has happened more then once being there are more objects in space then grains of sand on every beach on earth. It doesn't stand to reason this happened only once considering any and everywhere on this planet life finds a way. So why wouldn't it on other planets that experience similar factors that lead to life finding a way? Granted the universe overall seems to favor life not being allowed as we know it, we have first hand experience here that even under the most extreme conditions... life finds a way.
You seem to like numbers, your body processes more instructions per second than every computer on Earth combined and does so using a meagre 20 watts of electricity, the number of processes between your eyes and brain is greater than every PlayStation 5 combined, if the genetic code inside your cells was written into average sized books piled on top of each other, it would stretch to the moon and back over 500 times. DNA is the most complex code ever discovered, it is read in multiple directions and generates new instructions via a complex folding technique that cannot be replicated using supercomputers. DNA also utilizes encryption and an extremely complex error correction system. DNA also holds the claim of the most compact data storage system ever discovered and utterly shames all of mankind's methods to store data. A single cell in your body has similar complexity to a manmade city like New York and you have trillions within you, each day you lose 30-40 billion and your body replaces them quietly in the background. These nano cities go through 10,000 chemical changes per second. Despite 70 years of scrutiny from scientific communities all over the world the cell is more baffling to science now with every layer revealing more and more complexity. The human brain can comprehend abstract concepts like numbers, emotions, metaphors, and abstract actions, these can only reside in a mind. To accept evolution as the cause of all the previous you have to embrace the absurdity that matter without a mind and therefore incapable of understanding abstract concepts, including the ability to 'think', supposedly over the course of time, using unguided, random mutational processes without intent constructs a complex brain that is capable of understanding the abstract concept of numbers, utterly preposterous! God created life, inline with every observation ever made, that the source of complexity and information is always an intelligent agent. You can pretend that complexity and information beyond human capabilities comes into existence via lifeless, mindless, molecules, but that has and will never be observed. Give the glory to God, your creator.
FOR GOD'S SAKE! We're standing on Earth 1.0 right now, the ultimate Earth-like planet. If we have proven unable to pick up the empties and hose the place down periodically, why do we think we'll do better elsewhere? I suggest that it would be faster and cheaper, with a better-end product if we terraform Earth 1.0, rather than continuing to shit where we sleep, necessitating an Abandon Ship for a 10,000 year Ark ride to uncertainty. And it's delusional to think that we will EVER find a more perfect double for Earth. Remember, we need to replicate size, mass, magnetic field, day length, a moon (size, distance, tidally locked), climate, star size and luminosity/spectrum -- for STARTERS. Get any of those a bit wrong, and our Neolithic minds are going to experience a buffer overrun. WE ARE MADE FOR THIS PLANET, and should only abandon ship if it explodes. Remember, if we have the capacity for learning from our mistakes, we SHOULD know that, just because we CAN do something does not mean we SHOULD. Hubris and optimism are our greatest faults. We need to stay put, and just learn more responsible behavior. What a concept.
NASA is just a story telling machine and this woman is a mental midget getting paid to feel important doing nothing. Scientists got rid of God from their little minds as children and now are stunted at that level of development.
The planets that are not in earth's plane, cant we check their period using the light of a star from behind it?(from another solar system)? Would that add a lot of samples to our statistics?
Very interesting and not to be the pessimist but aren’t we wasting our time because we’ll never get to it even if we find Earth 2.0 and the way we’ve been treating this very planet I guess that’s a good thing!
I see all the negative comments about what is currently a fact of physics as we know it. We cannot get there. We are not even close to being able to travel the millions and millions and millions of kilometres that would be required. Look at the time and cost of trying to get Mars. This is extremely difficult, just trying to get mars.
So part of the mission will be to work out where the snowline is for each star so we can predict the goldilocks zone for each sun like star or can we already do this? Obviously the snowline will be different for every star and will dictate where we will need to look for earth like planets?
I think their philosophy is we’ll make the technology to get there once we know it’s worth building (as in they don’t wanna spend tons of $$ if it’s not actually habitable)
@@kwimms Have you ever heard of parallax? Have you ever heard of the electromagnetic spectrum? With knowledge of parallax, you yourself, with a little effort, could estimate the distance to objects in the sky. With knowledge of the electromagnetic spectrum you could ascertain the elements that must be creating the lights. I like the strength of your personal conviction, and I think it could be better used.
The Drake Equation (just my amateur's thoughts) So the Drake Equation attempts to quantify the number of advanced civilisations that might exist across the entire universe - but most of the values for the equation’s variables are, currently, not accurately (empirically) known and so the whole exercise is really just a ‘tool for thinking’; that is to say it helps us think about the right things as we try to assess if there are other civilisations out there and, if so, how many there might be - it’s very tempting to say that, statistically, in an infinite universe, there must be infinite advanced civilisations - but then when you look at humanity and our home planet, there is a very long list of very unlikely events that had to happen before we could evolve - and we (humans) therefore seem to be, statistically, extremely unlikely…….. the truth is, right now, we have no idea - we might be completely alone - or the universe might team with intelligent life - and both possibilities seem equally amazing to me…….. But if we can find evidence of life - any sort of life - on another planet or satellite or any place off this Earth, then the odds tip massively in favour of there being intelligent life out there somewhere……….. Great talk BTW:)
The sheer extemporaneous brilliance, excitement and self deprecating good humor displayed by this presenter speaks well for humanity's potential.
She should go do something useful like bake a cake instead of babbling on...
I am truly grateful for such gifted science communicators. Thank you for a gripping talk and for an audience with intelligent and focussed questions. I was not so far off the pace in my understanding but now I know more about where the holes are in our data gathering abilities and what is planned to overcome them. Thank you.
brilliant talk! And Jessie you present stuff with such a great enthusiasm!
It needs a lot of enthusiasm in order to cover the non-sense she says, for the novice audience. I mean one has to be more humble when she's building the whole argument on spurious shadows.
What an ignorant comment. You have pure ignorance. Pure ignorance is when one doesn’t understand the data or concepts, and instead of educating yourself, you just dismiss it.
Excellent presentation, Jessie. Loved it, thank you !
Great presentation. Thank you!
Knowledge destroys fear.
True. Problem is we have too many people that fear knowledge. Hopefully we outgrow that before we destroy ourselves. Then MAYBE.. just maybe we can make it to interstellar exploration.
Before Earth 2.0 we have to stop the relentless destruction of Earth 1.0 !

Without being able to handle Earth 1 with care ... Earth 2 will just get destroyed... Let's fix Earth 1 environment .
Personally i think this is a stupid concern. We already have earth 1.0 and we’re not doing a good job taking care of it. It’s human nature to be concern about “today” and we’ll leave it others to worry about tomorrow. It requires a couple of generations acting in cohesion to fix global warming for future generations. It requires foresight. Meanwhile you’re looking for earth 2.0, the money and especially the time it would take to get there considering the distances, it would take generations. Yes, the first pilots will die, your seeds will grow and die or be nurtured in incubators for centuries. So again, foresight is required. The same foresight we’ve shown we aren’t capable of using in unity to solve global warming now.
Amazing lecture delivered by Dr Christiansen. Just a small detail. Dr Christiansen said that Jupiter has 1% the mass of our sun but it is more like 0.1%.
Jupiter is 1000 times less massive than the Sun.
Jessie bravo
A nice presentation and work. What's the point? We'll never go there unless someone develops FTL travel which seems unlikely at present. Let's work on improving life on Earth 1.0. Keep the dream alive though.
I bet there was a hominid way back in pre-history that saw the hominid that was discovering the wheel and immediately went into a stupid rage because what is the point!!?!?!?!?!?!
It goes hand and hand. If we wait for other things to happen first there may never be a first.
Eventually there will be robots light enough to accelerate to 90% speed of light to explore other stars. Slowing down, that’s a tougher problem.
Perhaps there being worlds in which everything lines up to where intelligent life can evolve is rare, it still makes sense to think this has happened more then once being there are more objects in space then grains of sand on every beach on earth. It doesn't stand to reason this happened only once considering any and everywhere on this planet life finds a way. So why wouldn't it on other planets that experience similar factors that lead to life finding a way? Granted the universe overall seems to favor life not being allowed as we know it, we have first hand experience here that even under the most extreme conditions... life finds a way.
For sure there is other life out there.
You seem to like numbers, your body processes more instructions per second than every computer on Earth combined and does so using a meagre 20 watts of electricity, the number of processes between your eyes and brain is greater than every PlayStation 5 combined, if the genetic code inside your cells was written into average sized books piled on top of each other, it would stretch to the moon and back over 500 times. DNA is the most complex code ever discovered, it is read in multiple directions and generates new instructions via a complex folding technique that cannot be replicated using supercomputers. DNA also utilizes encryption and an extremely complex error correction system. DNA also holds the claim of the most compact data storage system ever discovered and utterly shames all of mankind's methods to store data. A single cell in your body has similar complexity to a manmade city like New York and you have trillions within you, each day you lose 30-40 billion and your body replaces them quietly in the background. These nano cities go through 10,000 chemical changes per second. Despite 70 years of scrutiny from scientific communities all over the world the cell is more baffling to science now with every layer revealing more and more complexity. The human brain can comprehend abstract concepts like numbers, emotions, metaphors, and abstract actions, these can only reside in a mind. To accept evolution as the cause of all the previous you have to embrace the absurdity that matter without a mind and therefore incapable of understanding abstract concepts, including the ability to 'think', supposedly over the course of time, using unguided, random mutational processes without intent constructs a complex brain that is capable of understanding the abstract concept of numbers, utterly preposterous! God created life, inline with every observation ever made, that the source of complexity and information is always an intelligent agent. You can pretend that complexity and information beyond human capabilities comes into existence via lifeless, mindless, molecules, but that has and will never be observed. Give the glory to God, your creator.
What is the price of that real estate? I think I’ll stick with earth
She is just awesome.
Delusional.
Why are so many of the comments idiotic? Did some science-denier share this on "X"?
Idiocy is a direct function of the internet. Which group do you see as 'science-deniers'? Pointing out our inability to get there or proposing we try?
The internet attracts stupid people because they can exhibit their stupidity to the world, which for some reason gives them a big kick.
Neat tune idea.
Why are the comments filled with Fox News talking points?
Lets start of with CGI and then more CGI. People are so gullible.
from action to words
FOR GOD'S SAKE! We're standing on Earth 1.0 right now, the ultimate Earth-like planet. If we have proven unable to pick up the empties and hose the place down periodically, why do we think we'll do better elsewhere? I suggest that it would be faster and cheaper, with a better-end product if we terraform Earth 1.0, rather than continuing to shit where we sleep, necessitating an Abandon Ship for a 10,000 year Ark ride to uncertainty. And it's delusional to think that we will EVER find a more perfect double for Earth. Remember, we need to replicate size, mass, magnetic field, day length, a moon (size, distance, tidally locked), climate, star size and luminosity/spectrum -- for STARTERS. Get any of those a bit wrong, and our Neolithic minds are going to experience a buffer overrun. WE ARE MADE FOR THIS PLANET, and should only abandon ship if it explodes. Remember, if we have the capacity for learning from our mistakes, we SHOULD know that, just because we CAN do something does not mean we SHOULD. Hubris and optimism are our greatest faults. We need to stay put, and just learn more responsible behavior. What a concept.
NASA is just a story telling machine and this woman is a mental midget getting paid to feel important doing nothing.
Scientists got rid of God from their little minds as children and now are stunted at that level of development.
The planets that are not in earth's plane, cant we check their period using the light of a star from behind it?(from another solar system)? Would that add a lot of samples to our statistics?
So beautiful ❤️
I wish she covered more on the detection of life elements in the atmospheres in relation to ideas such as assemble theory.
I'm touched and would consider a job with your organisation if there is any !🤔😀
Very interesting and not to be the pessimist but aren’t we wasting our time because we’ll never get to it even if we find Earth 2.0 and the way we’ve been treating this very planet I guess that’s a good thing!
I see all the negative comments about what is currently a fact of physics as we know it. We cannot get there. We are not even close to being able to travel the millions and millions and millions of kilometres that would be required. Look at the time and cost of trying to get Mars. This is extremely difficult, just trying to get mars.
Great stuff
Yet, we know so little.
From a planet hunter who needs regular fundings I would not have expected less 🤓
We haven't finished ruining this planet yet!
Some experts telling public that planets orbiting red dwarfs is our perfect new home , lol
Could you tell us which potential Earth 2.0 planets have Earth Similarity Index of 1.0..Closer to 1.0 meaning very close?
So part of the mission will be to work out where the snowline is for each star so we can predict the goldilocks zone for each sun like star or can we already do this? Obviously the snowline will be different for every star and will dictate where we will need to look for earth like planets?
Question we have looked so long, when do we admit failure
I think their philosophy is we’ll make the technology to get there once we know it’s worth building (as in they don’t wanna spend tons of $$ if it’s not actually habitable)
There can't have been a single person who reasonably believed there weren't planets around other stars.
There are no other stars, never mind planets. Show me one. All you have are lights in the sky that move in patterns. Nothing more.
@@kwimms Have you ever heard of parallax? Have you ever heard of the electromagnetic spectrum? With knowledge of parallax, you yourself, with a little effort, could estimate the distance to objects in the sky. With knowledge of the electromagnetic spectrum you could ascertain the elements that must be creating the lights.
I like the strength of your personal conviction, and I think it could be better used.
The Drake Equation (just my amateur's thoughts)
So the Drake Equation attempts to quantify the number of advanced civilisations that might exist across the entire universe - but most of the values for the equation’s variables are, currently, not accurately (empirically) known and so the whole exercise is really just a ‘tool for thinking’; that is to say it helps us think about the right things as we try to assess if there are other civilisations out there and, if so, how many there might be - it’s very tempting to say that, statistically, in an infinite universe, there must be infinite advanced civilisations - but then when you look at humanity and our home planet, there is a very long list of very unlikely events that had to happen before we could evolve - and we (humans) therefore seem to be, statistically, extremely unlikely…….. the truth is, right now, we have no idea - we might be completely alone - or the universe might team with intelligent life - and both possibilities seem equally amazing to me…….. But if we can find evidence of life - any sort of life - on another planet or satellite or any place off this Earth, then the odds tip massively in favour of there being intelligent life out there somewhere……….. Great talk BTW:)
