Exoplanets: The Search for New Worlds
Vložit
- čas přidán 13. 06. 2024
- A few decades ago, we knew of no other planets beyond those in our solar system. Today, astronomers have confirmed over 700 planets circling other suns and believe billions more lay undiscovered. These new worlds have smashed conventional assumptions, revealing planets orbiting multiple stars, planets that don’t orbit stars at all, and at least one as airy as Styrofoam. The incredible boom in planetary diversity raises tantalizing prospects for an Earth analog that could harbor life-as we know it, and as we never imagined it.
This program is part of The Big Idea Series, made possible with support from the John Templeton Foundation.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

@8:52 the guy controlling the mic volumes woke up from his nap...
I used to be a mountain guide in Himalaya and one-night i was on a plateau in wild far from the civilisation and midnight i came out from my tent then i saw a dark night with lots of stars and i saw the Milkyway too it was so beautiful that I sleep out side of my tent. After a little while i feel the rotation and the dark night was no longer very dark it became dark blues because of the stars light i guess,by keep watching night sky I also feel the gravity and the sensation was like falling but very beautiful way, first thought was space must be like this for astronaut then second thought was this is a space and i am on one very big ship. Queries its looks like our fundamental needs. Then again how i know i been to school first time when i was 37 years old and still not finish.
2018 came and went but finally it just launched December 24th 2021 during this horrid pandemic. Congratulations guys!!!
Great video. Terrible mics and volume control though. Yikes
I enjoy watching these Videos.
Natalie, you are flipping fantastic! ;-)
Indeed. She is very good at speaking. I wish I was her friend.
Nathalie for the win..
Fantastic debate!
Wow what a great answer to why we focus on exploring space as a human race: 1:15:25
Anyone know why isn't PSR1257&12 system (The planets found around the Pulsar in 1992) considered to be the first discovery of Exoplanets rather than the ones found in 1995?
Pulsar is not a main sequence star ??? So it did not count . Nobel prize said for the discovery of an exoplanet orbiting a solar-type star.”
Using orbital period as an index for the conditions of planets has a flaw. Stars of different masses will have habitable zone distances that scale approximately as the star's mass raised to the power of 2.0 (for red dwarfs) to 2.5 (for sunlike stars).
Sara Seager seems extremely frustrated that she isn't in charge of the discussion, and becomes visibly pouty several times when she isn't allowed to control the responses of the other speakers. She would be better suited to speaking alone. Several points were lost due to her interruptions and attempts to redirect. If she'd stayed home this conversation could have gone in more in a more productive direction.
^some extra words there at the end. Oops.
While she is a brilliant scientist, I would find her abilities as a teacher rigid... not at all entertaining, nor thoughtful towards others, qualities any teacher should attempt to sustain during any conversation as to engage the mind. Essentially Ms. Seager distances her subjects... where we see the exact opposite of the other speakers. In all I found this episode educational, with points that may have been re-spun.
Exactly what I was thinking. I’ve watched many of these programs. In every one of them you could cut the tension, between Sara and Natalie, with a knife! Natalie even tries to compliment Sara several times, but gets blown off. Dr Seager is a big contributor to the field, but Natalie is much easier to watch and learn from
I agree. I feel like she was being very rude and argumentative. Especially to the host. She was disrespectful many times.
Well said sir. Very observant
Some people have commented on Sara Seager being a little frosty but her single minded drive is wonderful. We need more people like her if we are going to achieve these monumental goals.
Yes you are correct Natalie has a more relaxed way about her. Personally, I will overlook condescending as long as there is a drive to keep pushing the envelope of understanding. Space exploration suffers so much from underfunding that a few overbearing but get the job done people might squeeze budgets for all they are worth. Mind you I wonder how she reacted when the Kepler Telescope lost its last reaction wheel ?
Find more planets!!!
This was a wonderful video and it definitely gets me excited, but I just have to say:
Natalie Batalha is smoking hot.
It was a real shame that the Kepler telescope did not get past May 2013. Yes there will be lots of data still to analyse but another 2 years worth of data collection would have surely uncovered more earth size planets at greater orbital periods. I suspect that earth size planets that are in habitable zones closer to stars such as red dwarves will not be truly habitable due to high radiation levels.

Cool Discussion, but get a better Sound Engineer, please! The sound handling is terrible! :( You need a Compressor and a Limiter for the sound and addressing the Problem can be done in a Post-Production Process. It s not that expensive, believe me! ;)
i love space
10:20 Too big to be rocky.
There was another video I saw recently describing direct imaging (via what looks like an inflatable umbrella/flower) not sure if it was wsu or another chanel
What is the matter with the responsible sound engineer??
Was this filmed in 2012?
Man it sure seems like there's some tension between those two. I'm sure anyone who reads this can figure out whom.
Aww this is all pre Trappist-1 discovery. Just as well as the host's mind would have exo-ploded!
um, I think the exoplanets are really just... the remnants of our 'exoskeleton' being osmosis'd out (mineral style) through the pressure of our 'environment' . haah. 🌋
Dan Harris is not fit to be a moderator fur these discussions, unfortunately.
According to astronomer Frank Drake's equation, if there is on average one planet for each of the one hundred billion stars in the Milky Way Galaxy then there are probably at least a million technological civilizations in our galaxy alone.
Did you account for evolutionary issues? we could say there are 10 billion intelligent, technological civilization in our Galaxy....however, how long ago did they evolve, or how long til they do?
BlackZerod1 Did you account for evolutionary issues? we could say there are 10

do?
No but Frank Drake did in his equation....
Smarties are sassy
Two old men in a theater balcony;
"You think they'll ever find life on another planet?"
"What do you mean? You don't have a life on THIS planet!"
Ahhhhhh Hahahahaha!😂
Dat mind
Unfortunately could not continue watching. I’m not doubting for a moment Sara Seagal’s intelligence and expertise in this matter, but she is far to aggressive and over bearing and continually talking over the top of everybody else. At one point she was asked a question and replied we have already covered this. It should be friendly and informative and allow those with an interest too listen learn and enjoy.
Totally agree
I consider the host is not at the level of the panelists...
DO NOT run alone at night !
Hi
For some odd reason... I am HUGELY attracted to Natalie. O_o Its her smarts. hehe
Harald Scheucher
She is very attractive and interesting, while Sara is highly getting on my nerve.
Bradley Carls great legs too ;)
+Bradley Carls all this time, i think sara seager is one of most sexiest scientist, now i just found this girl named Natalie is even more sexy and attractive...agree with you ....Natalie is very attractive , is even more compared to movie stars, perhaps because she has the smart thing along with her great looking.....
This host turned a science discussion into a big joke. I wish they had a different host for this. He needs to be back with the celebrity interviews not science...
documentaries
Waly ballago seck
Wow, is the host asking idiot questions, but, to be fair, he did claim he was not familiar with the subject. If you understand NOTHING about the subject, why be the host? Get your science reporter to mediate...
Love it except for the moderator. He is really bad.
Wow, I feel bad for the host. They're being pretty obtuse to him.
+Zak Hutchinson No, Sara Saeger was. She's really a pita, always lecturing other peaople on the podium, interrupting, showing them they are inferior to her.
+ozdergecko Dude I think it's cos Sara Seager is a mechanic, a doer, builder of science stuff-she needs to stop people waffling ---I reckon !!!
I got what you said. They are scientists. They are not used to talk in a simple way so that common people are able to understand.
Sara seems to be a very hard person.
100,000,000,000 planets in the you-knee verse ! so ours is not so rare. so let's let it go down the drain by destroying it by over-consumption of its resources and ruining its eco-balance. I am relieved.
28 minutes or so and I had to go watch something else for a bit because of that incompetent host. To embarrassing, couldn't keep watching.
I will come back and watch the rest latter.
Well, the host was right, hes a ignoramus. But listen to all the info the scientists offer and it over shadows his ignorance.
Yeah, they couldn't have chosen a better host, really. He's not just an ignoramus, he's a bit of an *** as well.
Planets are everywhere. Planets with physical and thermal parameters similar to Earth's are not uncommon. Simple life probably exists here and there. But multicellular life will probably be very rare because of the hurdles involved in getting simple life to collaborate on a survivable multicellular organism. Intelligent life will probably be even rarer, since intelligence is costly and, under the rules of evolution, must pay off more than it costs at all times.
as much as i like the WSF, the host must know atleast the basics of science!, he asks kinda "stupid" questions for a panel like this!
Science chicks... they're so hawt! :P
I have nothing to do wanted to talk
The host ruined the momentum of this presentation by continually drawing attention to himself, I had to stop watching after the first thirty minutes because of his input.
They sound like salesmen from Scientology.
This host had such lame questions to ask... Please use a more thoughtful host with better questions next time.
Can one be any more rude than the scientist who keeps saying "back it up" and "You've already declared yourself as the ignoramus"? I can do without seeing or hearing that personality type. Everyone else was great though, except her. She should spend some focus on learning how to talk to people.
The host is very annoying. Probably because he is a bit naive.
+Lukas Morkunas The Moderator represents the usual non-informed individual. I had to stop watching this because the moderator kept pulling the conversation here then there and everywhere. He's treating this panel like they are on a freak show and asking them to showcase their "specialties" when it should have been a panel of discussion and debate. The moderator had VERY LITTLE knowledge on the topic of the panel so a lot of "dumb" like questions were asked. It just annoyed me that the moderator had very little knowledge knowing he was going to moderate the "discoveries and search for exoplanets" panel. To be honest what do you expect from a guy who hosts a show on the ABC network, I just wished they had put someone in who wouldn't have asked questions that took time away from the panel to debate on some serious stuff.
+Lukas Morkunas Yes and it seems to me like he is engaging in a form of humble-brag
+dave smith Seems a bit harsh, the moderator has to speak to folks who have zero knowledge about exo planets and convey information to them. Could you do better??
He is doing what gidbalzar said, asking questions that fill in gaps for people watching that wouldn't understand what they are talking about otherwise. Many people may be just getting interested in space and have not yet learned why planets must be gas giants once they reach a certain size. It's just like when a student in a college class asks a really basic question to the professor about the topic, but all the students are grateful because it was on their minds as well.
I have a feeling he's playing Dummy's Advocate.
bunch of nonesense
Sarah is so rude....
Arrogant AF
@@terensaurus...who me or Sarah? Lmao.
Sarah! Sorry I wasn't clear on that. She was so annoying. I was looking through the comments to see if anyone else agreed.
@@terensaurus haha all good dude 😊
terrible host, too bad for a nice topic
The woman with the leather jacket is a really arrogant and unsympathetic.
She is one of the world's primary experts in exoplanets. And she is confronted with a host for this panel that is a bit of an idiot
such an arrogant species
if you want to find a new world READ THE BIBLE and you will find one
Great scientist, great scholars, great professors for such a lousy host. Even disrespectul, with silly questions and those kinds of remarks, like "your aversion to personal opinions". That was way out of line. It denotates a lack of intelligence and very little respect for serious scientific work.
Re: closing thought @ 1:23:01. "Harken back to something that Neil DeGrasse Tyson is famous for saying... We are made of star stuff..."
Tyson was plagiarizing Carl Sagan.
"The atoms that comprise my body were manufactured in the core of a star, and what that means is that we are all connected on a fundamental level."
Hold up. That's not the level of connectedness that's important. That we are all made of star stuff is no more relevant to our judgment about whom to like, whom to favor with patronage or loyalty, than is the fact that we all came out of the same Big Bang. That's not something that's going to make lions, hyenas, and lambs all live peaceably together.
The level of connectedness that is important is biological similarity. What can replicate, most nearly, the kind of thing that you are, is what you should favor with patronage and with loyalty.
Marry within your own race, always. Have children of your own, unmixed race, only.
Plagiarizing would be a bit of a strong word. He often says, that it was Sagan who coined that phrase. Given the general reverence he has for Sagan I would suggest it has more to do with honoring his legacy.
So much for that. The rest of your post, however, i will not let slide so easily. Congratulations for pushing both of my buttons at the same time: Parading scientific ignorance as wise knowledge and then for promoting racism? Good one! Here's the thing: No living human today meets the biological standard of being a different race than any other living human. Heck, we are still debating whether we can classify Neanderthals as a separate species as they are floating right around the edge of just being a race of H. sapiens; just for a little perspective here. Even more to the point: The only thing we can talk about are local subpopulations, not races, and they barely don't exist anymore anyway. I guess you weren't aware, that all Caucasians and Asiens together with a population of east-central Africans constitute a group with less genetic diversity than this African founder population with other local African populations? (To put it easy: Whites are more closely related to a part of the 'African race' than all Africans are to each other. Secondly: Children of mixed couples are not less fit than children out of a long isolated subpopulation, on the contrary: Their immune systems tend to be more robust for example. And a very obvious pointer by the way is that statistically descendants of mixed couples tend to be more attractive to other people than average. Your comment even could be used to advocate incest, which kind of would happen if a gene pool would deplete enough in diversity as to have the same effect. And inbreeding would sort of be the only way to make sure you are not too far apart, genetically. As it might very well be, that a woman in Ethiopia has more in common with you genetically than the girl next door.
If nature 'wouldn't want' two people to have children, it simply wouldn't 'let them'. I guess you also aren't aware of the fact that quite a substantial percentage of pregnancies abort within the first few days without us ever realizing? That is in large part due to genetic incompatibilities (to put it very easily), and as far as we can tell the rate isn't different for mixed or non-mixed couples.
So, as a biologist I hereby recommend to all those having read the original comment and my answer to it: Procreate and/or marry with whomever you fall in love with and feel it right to have children with, no matter the skin color. Apart from general infertility, nature will not prevent you from doing that.
And my second recommendation is, that the OP can go procreating with himself.
If you want to look at it that way, Sagan was plagiarizing Crosby, Stills, and Nash.
catty blue shirt woman totally missed the point of why gas planets are big and terrestrial planets are small... jovian planets are typically far away from the sun because the cooler temperature allows gas to form as an atmosphere. It's called past the 'frost line' for the solar system, that would be the good ol' asteroid belt. Thus: they expected the closer ones to be terrestrial but they "knew it couldn't be"
Quite a few comments expressing displeasure listening to Sara Seager. She is one of the top Planetary Scientists in the world who is fondly respected by her thousands of students. The people who don't like Sara probably flunked their science courses and dropped out of school, sold back all their textbooks and have been mad about their unsuccess ever since.
John P Curtin newp...never took her course, don’t know her, never met her... but first impressions do matter. No doubt she is smart...much smarter than I. But one can be smart and polite at once. People may not like her because she is off putting because of her attitude, which is fair. Not all dislike is rooted in jealousy.
not sure if the host's rubbish or the scientist lady on the left is just rude,but i'm finding this irritating to watch and i'm less than 10mins in. Wish she would stop interrupting and saying "lets back up a minute" constantly. she seems totally pissed off with the rest of the people on the panel. Can't stand her...
Boring
