- Lucie Green takes us on a journey from the centre of the sun to planet earth in a run-down of the latest solar physics research.
Watch the Q&A here: • Q&A - A Journey to the...
Lucie's book "15 Million Degrees: A Journey to the Centre of the Sun" is available to buy now - geni.us/2oB8V
110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system.
Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this? Since the Royal Institution was founded in 1799 our knowledge of the Sun has changed dramatically and much of the work was carried out at the Ri.
Join Lucie Green for an enlightening talk, taking you from inside the Sun to its surface and to Earth, to discover how the Sun works, how a solar storm can threaten the modern technology that society relies on and more of the latest research in solar physics.
Lucie Green is a Professor of Physics based at the Mullard Space Science Laboratory, UCL’s Department of Space and Climate Physics. She studies activity in the atmosphere of our nearest star, the Sun. In particular, she looks at immense magnetic fields in the Sun’s atmosphere which sporadically erupt into the Solar System.
Lucie is very active in public engagement with science, regularly giving public talks and appearing on TV shows like Sky at Night.

I got through half this video before I just had to order her book "15 Million Degrees" - and it's GREAT!
Her video on Pornhub is even better!!!!
Yes I read It it's amazing
As soon as she said I don't have to buy the book, I had to buy it as a matter of principle
@@L0rdL0ki she was using "reverse psychology".
Some time try it on a female you like. Tell her you're not interested, she'll be yours in a week...

Absolutely amazing lecture , thank you Lucie , I will be buying you're book , for sure
The Royal institution channel is very informative and i like it so much and i like the topics they discuss and share with the world . Thank You for the efforts !
I've got Lucy's book "10 million degrees" a couple of years now, and I have to admit it was an excellent read. The section dealing with magnetic reconnection really grabbed my fascination.
That was a great talk! Thank you, Lucie! I study physics, and learned so much about our sun.
i wish this much longer, talk like this is far better than watching any tv show or movie.
She really really loves her job...
I hope one day I find a job I have so much enthusiasm for...
Absolutely fascinating! Very well prepared speech.
How I wish I could know, understand and recall everything that desk has heard. I'd be so unbelievably smart maybe even wise.

awesome talk! thanks for posting this!
I read this book last month, its one of my favorites, thanks Lucie for being an amazing scientist
Great presentation. I hope more information and visualised models become available to help show what exactly drives the sun to do what we observe.
I saw this video scrolling through my subscriptions "it's Dr. Lucie! I have to watch it!"
Me too!
SPACETV Are you both well ?
Silverback 29 Yaba daba doobie time!!
You could safely say her work revolves around the Sun ;)
Tomasz W child's play
She thinks the earth revolves around her work.
She thinks the sun shines out her arse!!!
tadam! tsss.
Fantastic lecture. Thank you.
I love how the SDO data is open and free to the public. I have an app on my phone that gives me the most recent set of SDO pictures. Really cool. You can go back and view the Sun on your birthday, too, or whatever date you want (within SDO records, of course)
Wow! The image at 03:26 was spectacular. I've never seen that before. I'm looking forward to the rest of this lecture.
Wait to about 10:00 and on.
My mind went off like that little video.
OOOO.oooo
...And then I was bound to finish the entire lecture.
I understand about 1% of all of this, but find it fascinating, and enjoy watching all of these lectures.
Very nice channel, hope videos will be added often. I keep following.
Nice and informative video.. Thank you
The talk is amazing.
Excellent current information and lecture...
Studying the sun seems like a pretty cool job.
Absolutely brilliant!
Excellent, thankyou. Heh, just bought your book online.
My favorite mystery of the Sun is how the photosphere can be so much cooler than the layers above and below it. My idea to explain this is that the combination of high gravity and especially high magnetic field density constrains the motion of atoms with more force than the temperature driven kinetic energy of the atoms. The amount of electrons falling back towards a ground state is likely higher in this region as well, creating something analogous to evaporative cooling right at the top of the convective cycle where energy escapes at the speed of light and material at the speed of the solar wind. Magnetically constrained motion would electromagnetically overpower the motion phenomenon we observe as temperature and the most energetic elements are rapidly leaving the photosphere is a tidy hypothesis. How can we test this now with current equipment?
My first encounter with the term 'coronal mass ejection' was years ago in star trek next gen, their shields held.
Make it so number one
Dukky Drake Sounds painful
My first encounter with the term "coronal mass ejection" was in my girlfriend's mouth...😁😁😁
First bit of science EVER in Star Trek then.
A TEENTY-TAHNY-TINY bit of science mixed in with all the claptrap that makes up 99.9% of that show...
Fascinating.
Has anyone else noticed the nice funny bit about sunspots in the Japanese anime film "From Up On Poppy Hill" where the astronomy club boys say they had been studying sunspots for years... and not made any new discoveries yet!
I'm a big fan of the Sun, so I appreciated this talk. A lot of excellent information presented clearly.
I wouldn't ''fanolise'' the Sun, it wouldn't appreciate me!
Wait to about 10:00 and on.
My mind went off like that little video.

Great video thanks .:)
They also use absorption lines to analyze the make-up of the atmosphere of exoplanets. Very cool approach!
brilliant! absolutely brilliant!!
Lucie, that was awesome. If I were in the audience at the end the question I'd ask is can any of this (the last part about magnetic fields/ropes/kinks) be applied to pulsars, quasars, or any other high energy phenomena ?
You are,
SOOOO MUCH EASIER...

almost unbelievable we can even send our imagination in to the heart of the Sun.

Is the program used to generate 'difference images' open source? You mentioned your colleage Dave Long created it.
This is a great talk. My recommendation is that if you are going to model flux ropes then you also need to model the spacetime superfluid and how it behaves at this matter-energy temperature and gradient.
How do coronal mass ejections change the shapes of the magnetic fields? Is it the positive metal ions that are being ejected from the surface?
I wish she would have given us a sense of how much mass the sun is losing every second or day, and how that loss of mass affects the earth's orbit.
Scott Bryan The sun will become a red giant and the earth will be scorched so it doesn't matter lol
The computer generated images of the theorized Flux rope, could be spot on. The rope turning on itself, causing a electrical short. There by causing a explosion. Like a transformer or a wire carrying high electrical charge. looping/bending around and touch at wires midpoint shorting out.
When was this produced Transit of Mercury doesn't happen next till 2019 or am i missing something?
Why isn't this video captioned like many other RI videos?
So can you use a spectrometer to measure the light deep inside the earth to measure what the centre of are planet is made of? Has anyone tried this?
If you were drawn in by the click-bait subject line, it begins 51:53 into the video and there's not much to it. It's a pity that The Royal Institution would stoop so low. This is an interesting talk which can stand on its own without a tacky title.
The title is from her book - I've noticed this with other speakers as well.
Grow up
Hurricanes are atmospheric vortices on earth and sunspots, being vortices on the sun, could technically be considered solar hurricanes. Solar tornado is closely analogous, especially if earthly tornados ran from surface through lithosphere. You have the best job on the planet, bar none.
While watching this an odd thought struck me. We are pouring masses of research into making a practical fusion reactor, but we already have one in our sky. All our energy (except, ironically, nuclear) has ultimately come from that natural fusion reactor pouring its energy into our biosystem. We even use its fusion power directly when we deploy solar panels. Surely it must be worth putting major effort into developing ways to use our already existing fusion reactor more effectively?
there is a lot of research put into making more energy and resource efficient solar cells, though having the fusion here on earth would help us greatly in understanding, how it works.
Also, why not?
Magnetic fields in environments above the Curie Point?
I think that the book has more than what could be explained in an hour. Generally books do.
Kenneth Florek It takes about 17 hours to read out loud a 700 page book , just saying lol.

"The Apollo astronauts reported having these flashing lights in their eyes, even when there eyes were closed."
Almost correct.
The fact is we didn't hear these reports from any Apollo crew. They came from the shuttle crew who repaired the HST lense fix in 1992.
That detail may turn out to be significant, or, for you it may not. But nice to get it right, surely.
Apollo astronaut were asked about this in interview quite recently. The answer was not reassuring for those of us who still want to believe in the veracity of the moonlandings.
That's science
Thank you for presentation. A maybe stupid question, but why does a big mass of atoms becomes a star and another time a planet. Is a planet a star without nuclear fusion ?
The Solar wind as seen in the views of Earth, seem to suggest that the quantum fields are very much a part of how light waves act in their motion across our solar system.
By studying Jupiter, scientists will get a better understanding. I believe Jupiter almost became a second sun in our solar system. Similar makeup and its atmosphere move in a similar way. Kind of a COLD fusion copy of the Sun.
That's hot, if we go there, better land at night.
...on the shortest day, to give us the most time to have a look around...
Isn't the 'flux rope' just plasma that has acquired enough energy to break loose the constraints of the magnetic fields holding it?
Did not a recent observation show that the fields influence the sunspots FROM ABOVE rather than from below (below the sun's 'surface')? That was presented at Suspicious Observers last week iirc.
It's a mixing action...similar to boiling water undulating, as hotter water rises from the bottom of the pot towards the surface...
Just had to pause and verify about Thomas Harriot's sungazing habits.
It's true!
Well, you can't be genius in everything. :)
Latest pictures of the sun (photosphere I guess) taken from the suns poles by satellite show it to look like a can of corn with each kernel the size of Texas. I like your coronal magnetic helix twisting images. Thanks
I can't work-out the relevance of comparing that UV spectrum to shutters across a window, which don't separate light of different wavelengths. I suppose, i blocking strips of light from entering the room they will cast a striped pattern of a wall behind, but it really isn't the same thing, or am I just being slow on the uptake?
Search for "diffraction grating", and you will see what she meant. It's simply equivalent to a prism, but unlike prism it does not absorb some light, and much lighter so cheaper to put into orbit.
Thanks for the explanation. I see that she's using equipment which has the effect of a diffraction grating, what I don't understand is the direct comparison to shutters which don't act in the same way.
I think she meant window shutters. You know, many little slits separated with equal distance. Check this out, it will make sense: socratic.org/questions/why-is-diffraction-grating-more-accurate-than-double-slits-to-measure-the-wavele
Thanks, but I do understand what a diffraction grating is. I'm trying to explain that, because window shutters don't separate the spectrum, I don't think the comparison is valid.
They separate the light in microwave range. You just don't see it. She was just giving an example for kids to visualize.
They are what is known as the solar wind... On witch we and all the planet are being pushed away by the Sun and we are riding around the Sun on. But the Sun's gravitational force holds us in a certain perimeter/ringed/layered area around it.
Mediated to the center of stars are protons, made of positrons, from the Inertial plane/Counterspace. The first to leave the Inertial plane is Dielectric energy. This is when the Universe and Time started. Inflation.
Then, Dielectric Voidence Field/Magnetism was created from the Dielectric energy. The transverse waves that EM waves perturbate on/in Tesla nodes. The Grand Expand. Magnetism gives Magnitude to the Universe.
Gravity is Dielectric Voidence Field/Magnetism returning to Dielectric energy. No transverse waves anymore, just Dielectric energy. So, no light, in a Blackhole/Counterspacial Sink. Dielectric energy returns to the Inertial plane. The Inertial plane, "Condensate of Universe".

I'm surprised that she didn't mention the Chinese recording sun spots 800 BC if I recall correctly. Way before anyone else.. :

I need to know how much at to the center please?
Is that Fahrenheit or Celsius ?
Kelvin
So exactly what is the sun ?
Wow.... tough crowd...
Watching an Ri video is like attending a lecture at a good college . A valuable experience, from which one can extract knowledge , but not an entertaining one. They are excellent primary material that badly needs cinematographic editing before being presented to the on line public.

Quite a huge discovery that the sun has plasma and magnetic field.
An elementary school boy can do it with a couple of experiments.
If there is plasma it must have a field.
What a big news for a physicist oh boy.
You spelled center wrong
Old information. If you really want to learn about the universe, stars, what makes them shine how we can tell how far away they are just looking at their light, watch David butler's video books,
How fast is it, how old is it, how small is it, and many classroom aids..
Wow; watch a Tesla Turbine operate; the medium winds up the centrifugally, before you get that sudden change in the RPMs and you get that explosive POWER. VERY INSTRUCTIVE!
Imagine if we shared an atmosphere with the Sun and sound could travel between us. it would remove all of are atoms when hearing that hyper-ultra-sonic BoOM!
Suspicious Observers looks at this info daily. New techniques AND new ideas are happening!
53:50 Solar dynamo's ( the only reason i watched is what she ends on because its our limit of understanding ) We got a few things Wrong , in Short , The Solar Dynamo is a feedback loop machine . all the factors involved ,
-Gravity (mass)
-fusion
-Spin
- electro magnetism
-internal solar Lagrangian action(not points)
-fibonacci and jnhm matrix grid
-planetary energy ( orbits )
The Gravity / mass of the object , Controls how the dynamo/feedback loop will grow , or eventually die out ... Larger stars create a more powerful dynamo ( feedback loop of flow that makes a field that makes it flow faster that makes a stronger field ) that creates
more motion that leads to more heat and the extra mass crunches the core more , this can build up to a Super Nova , the larger the star the faster ..
The converting of the elements is NOT what power's the stars , the elements are more like a clock or fuse delay ...
Smaller stars create a less powerful Dynamo/Feedback loop , which make less heat , so you can get a star like our sun or brown dwarf , a Jupiter , or even a earth like planet that keeps a hot
core for billions of years ...
MASS
and the elements present simply determine what happens ...

Actually, it isn't. The center of the Sun is almost too cold to allow fusion.
Who besides flat earthers and their ilk would give this a thumbs down?
Huh?
"A Journey to the Centre of the Sun"? You mean A Journey to the Surface of the Sun, don't you? Was baited again.
either or, your still toast
Pink Floyd set the controls for the heart of the sun.
I think the title meant a closer scientific historical look at and our understanding of the phenomena of the sun, to the present day.
I think I'm a Si 7 person myself 😎

time talking about center of sun: 1 minute, time talking about surface of sun: 54 minutes. click bait anyone
ricktbdgc I'm looking for center of the sun knowledge , I may not watch the video now because of your comment lol thanks .
A journey ends at its destination, so it is inevitable that a video of the "journey" as it says in the title, will necessarily spend very little time at the destination.
What you want is a video called "The centre of the sun". I'm sure there will be one hereabouts.
Yes, I was hoping for a lecture on fusion, solar elements, photon generation, all the amazing stuff that happens at the core. Don't need more sunspot or CME stuff. I wish the title wasn't so misleading.
As I said above, the title isn't misleading. If you want to know about what happens at the centre of the sun, look for a video titled "The Centre of the Sun" not one titled "A Journey to the Centre of the Sun".
If I saw a video titled "Journey to Paris" I would not expect that to be a video about Paris. I would expect a video about getting to Paris.
That is a fair point. I agree with you.

I wonder if these flux bursts can someday be artificially created to propel spacecraft.

Spectrometer images of the sun just look like black metal album covers.
I've personality taken the spectra of the sun and it's full spectrum minus absorption bands. Definitely NOT a black metallic dot. Check your spectrophotometer, something's wrong with it.
Some of these camera's have so many dead pixels :D
It adds character to our videos, no? No? No, I guess not. We have a new camera now, you can expect less pixel death for any new talks we're going to film.
The Royal Institution Haha, I dont realy mind. It was just an observation ;)
can we expect 8K? :D haha
I freaked and thought my LG OLED suddenly had a bunch of dead pixels until the angle changed!
Could meteors, like ahmoah moah and comets, be hitting the Sun and causing some of these sudden ejections??
no closed captions for deaf people? wow!
The small amount of "center of the sun" material appears in the last few minutes of the video, making the video title clickbait.
Clickbait is not having content in the video that you show in the thumbnail. So no, this isnt Clickbait. Its called holding an audience. You put the interesting part that would appeal to alot of people, at the end of video so that you draw in an audience. RI is a charity, that put no ads throughout the entirety of the video. You get an ad at the start and then one an hour later at the end. If they were clickbaiting, youd be sitting through ads every 15 mins. Come back when youre properly researched and informed.
