Dr Naomi Rowe-Gurney is a JWST GTO postdoctoral research associate at the NASA Goddard Space Flight Center employed by Howard University. She is a solar system ambassador for the JWST working with Dr Stefanie Milam and Dr Heidi Hammel.
She obtained her PhD in 2021 from the University of Leicester working with supervisor Dr Leigh Fletcher. Her thesis used archived data from the Spitzer Space Telescope to study the thermal structure and composition of the middle atmospheres of the ice giants, Uranus and Neptune. She used the retrieval algorithm NEMESIS and built a consistent retrieval framework for the ice giant planets ahead of the launch of the JWST. Throughout the PhD, Naomi used her teaching experience to partake in significant outreach and public engagement work.
Naomi also engaged in considerable equality, diversity and inclusion work and was an active member of university committees, as well as promoting science to underrepresented groups. The majority of the engagement work she focused on was for the JWST and promoting its use for looking at our own solar system, especially the giant planets.
This livestream was recorded by the Royal Institution on 12 July 2022.

I fully respect a scientist that thinks their audience is grown up enough to handle the proper pronunciation of Uranus. We aren't, but I do respect it.
The Brits have always said it that way....
*cue Beavis and Butthead*
aaaaand we're done.
Except its not the correct pronunciation... its Latin and is pronounced the way the Romans pronounced it.
That last sentence really takes that comment to the next level. 🤣😂🤣😂🤣😂🤣😂
I know now I always hated that. It's like okay laugh have you joke I get it. But once were seriously getting down to business I think you should be able to get over it. Think of it this way when you go to the doctor does he laugh at you in your face over your small wee wee?. No. They stay professional. Some people are so base that they just can't get over it.
I was a friend of James Pollack, who also studied planetary formation, planetary weather and imaging technologies at NASA. He worked on the imaging teams for the early NASA probes, and was an openly gay scientist back when that was rare at NASA. He was smart, kind, collegiate and influential, and he would have been delighted by the JWST in its final form (if not by the name). He died early in the project's development.
Knowing him, he would also have been pleased that Dr Rowe-Gurney is now working in his field, with new technologies and new insights - and he would have been appreciative of her educational talents. He himself was not good at giving this kind of public lecture, because he spoke very slowly. That sometimes led people to underestimate his intelligence, which he handled with grace and humor.
I think of Jim fondly every time a major advance like this comes along - he would have loved to have been part of it.
Brilliant talk. Loved it. The talk was so darn good that it's made me even more impatient for what you folk are going to observe and find out about our universe.
"That bottom clip is from Martian , it's not scientific accurate representation of how we can loose Mat Damon , but martian storms can be very dangerous " 😁😂 loved that
Thank you for the usually overlooked detail of moving your own frame around to fit what we're trying to read. It shows that you're as excited to look at it as we are, even though you've seen it all before. This is one of the best work-from-home presentations I've seen from Ri, aside from Andrew Szydlo who has a lab either in or under his house.
To quote lyrics, from I believe it was "Starry Starry Night," those are in part, "Now I understand what you tried to say to me . . . ."
I graduated in Physics with Space Science from University of Leicester two years ago, and my graduation was yesterday!
Congratulations, and bravo for your patience... what a strange time we live in. Best of luck in your future studies/career!
Wonderful presentation. Dr. Naomi will be a science star.
We're going to need more data here... which specific type of star exactly? ;)
More interesting than an entire series of Brian Cox! Thanks for bringing back the proper pronunciation of Uranus - we really need to get over it!
Such an articulate, knowledgeable, and informative lady. Congratulations on your doctorate and thank you for this very worthwhile presentation. Let's just hope the JWST has plenty of time for making observations before further meteoric damage occurs.
To the doctorate-level commenters who didn’t understand this, she is saying methane absorbs red light meaning it makes white light passing through it appear blue. Especially obvious when looking at an atmosphere from outside the planet, which is why she mentioned water and ices. Water is obviously clear but Earth’s water looks blue from space, you know?
Thanks for articulating so well the purpose and future work of JWST and the areas of research you have been tasked with. That "Chart of Cosmic Exploration", something I had not seen before, was startling. In one spectacular graphic you get this profound insight into the mind-boggling technical understanding and capabilities developed over the years by the world's smartest thinkers. It encapsulates the powerful instinctive nature of mankind to explore the unexplored and find answers to the hardest of questions.
Awesome channel with awesome content and great quality as always say 🌍💖🔥🔥🔥
I also say.
Cheers from Australia :)
Wow! Such clear announciation - Teaching Physics in China obviously has payback! Can't wait for her to guest on the BBC's Sky at Night!
"are my favorites, Uranus and Neptune, so I decided to dedicate a whole chapter to them, because I can"
I love it :)
Very professional speaker. It was so easy to follow and understand what you wanted to share with us. Thank you from Tennessee, USA.
Naomi will be 54 when Uranus is visited, I will be in my 70's. These advancements are so special to see today and I think about so many people who have lived before us and how much they would have loved to see the James Webb. I believe that Carl Sagan and would have been glued to the monitor today and loving every image captured.
Hi Naomi Rowe-Gurney, that is a very welcome and clear explanation, thanks. I really loved your comment in between, when satring to talk about the Ice Giants (I dedicate a whole chapter to them, because I can (!!!). Great
As a science lover and especially an astrophile, I have seen The Royal Instituion videos without fail..... I loved this video so much that I tried so hard that explains jwst everywhere and I found here at the end..... so delighted😊😊😊😊
Same
Dropping her fresh new record Ice Giant Science 🎶🔭❤️
Great talk Naomi! Great to see you're at NASA and doing professional planetary Astrophysics!

Hi Naomi and welcome to the neighborhood! I'm "across the street" in Old Greenbelt. It truly is a small world after all...with a view to the expansive and ever-fascinating universe that we are part of.
Fantastic presentation, a great overview of the insights that JWST can bring to us from our own cosmic backyard.
(And aside from the pres itself, there's always a little extra fun to be had in reading comments from conspiracy theorists and CZcams Experts scolding a PhD scholar for getting it all wrong!)
What an amazing young person, you are one in millions, an absolute delight to listen to, not drawing attention to yourself for one alpha second, even when describing your education or background, thank you for your explanation in such an easy to listen and understandable manner. You are a pure delight.
i just saw her and she is black. quite shocked.
@@esecallum this is how you spend your time? Seriously?
@@esecallum What color is she suppose to be?
A serendipitous showing of the ability for crafted accidents to astound. Thank you to all who made this possible.
Thank you for a fantastic show. Can't wait for any science results.
Such a fascinating presentation, covering advanced topics in such an approachable manner, making all that is being learned with the JWST understandable for lay people, like myself! Thank you, Naomi!
At first I was thinking like ok some early pictures but now I desperately want to know the outcome of all of the projects highlighted (and more). Now I am really excited to see what jwst (and in combination with other instruments) help to discover.
Fun intro, thank you. I was not aware of how much local work Webb would be doing.
Naomi it was such a pleasure to listen to your presentation. Such eloquence and interested perfection. I look forward to future presentations of yours. I contracted at JPL for several years in the 80s and 90s myself. It is such an advert for a Black female scientist, even a Brit. I was born in London so I guess I’m a Brit too. Keep up the inspiring work. I’m sending a link to my daughters, a Lawyer and Sociology PhD, to make them jealous. Cheers, Steve
Proficiently narrated, as always. Huge thanks Ri.
Absolutely brilliant presentation, thank you very much
Great stuff. Great quality. Great representation.... And it didn't dumb down. Loved it. 🥰
This is amazing lecture. BIG THANKS for sharing!
When you do some of the in system observations, will you also have HST possibly imaging the same thing at the same time, so as to get a 3D perspective of active cloud features (in the overlapping imaging wavelengths), in as real-time as possible?
Well done Naomi. Great show.
Thoroughly enjoyed your content, Thank-you !

Our sky appears to be blue due to the interaction of sunlight with particles in our atmosphere causing light scattering (Raleigh Scattering).
It’s not specifically or solely due to the minute or trace amounts of methane in our atmosphere.
In fact if you remove all the methane from our atmosphere the earth’s sky would still appear to be blue. (The main gases involved in the Raleigh Scattering effect are Nitrogen and Oxygen which make up almost all of the atmosphere ~99%)
the blue in our sky is due to the reaction of all the noble gases, the voltage charge the higher you go being excited by the sun. Check out the noble gases used in making Neon signs to understand which gases and/or combination of gases make blue for a daytime sky and for the oranges/reds of sunsets etc. as the same gases used for neon signs are in our atmosphere and the colours of the colourless gases show colours to humans due to adding a voltage to the gases in the neon bulbs. Also a thick enough layer of any colorless gas looks blue because it scatters shorter wavelengths more efficiently, and the reason of more shorter wavelengths is due to the highest voltage being higher up in the atmosphere, where as the weakest voltage is closer to the ground.
Love me some James Webb talk. I want them to point it at a blank area in the Deep Field frame, and see if even more objects are revealed. What an incredible technical achievement and milestone for our species. Kudos to all the teams who worked tirelessly to make it happen.
One of the first images they released was a deep field. Took JWST about 12 hours (exposure time) to create a deeper deep field image than they did with Hubble over several days.
If you mean you want them to do an extreme, ultra 'super dooper' deep field, I want that too and I'm sure it's coming :D
There will be more galaxies in those dark spots.
So good information. Thank you.
Well done considering you have your PhD and are only 32, bet your folks are over the moon (since you are an astronomical scientist) Very well done, and easy to listen to and understand, thank you so much! Looking forward to more. It's hard to imagine that in Einstein's era that any discoveries you found would be published as a man's work! Thus Einstein's wife got no credit for her input. So glad that era is gone and you are the perfect example of what young girls need to see. It's the perfect time for you and what you do, perfect. Imagine what you will know and understand in 25 years.
I guess they launched it from Guyana for the "No ras" aspect of it all. Nice people there.
She can start by understanding why the sky is blue. She said the our sky is blue because of methane in the air. That was a very false statement for a PhD student.
@@yourmum5895 she has a doctorate and is not a student
Very intriguing video, with a lot of informative topics. Great job. Sending you all love, light, enlightenment, positive affirmations/ prayers and hugs that heal. 💝❣️💝💝❣️💝
Graphs, Glorious Graphs!
Love how much we can figure out at those distances
wonderful content. thank you
thank you for this presentation its amazing!
Something I would like to see, is Space-X "donating" a number of launches for pure sciences (call it compensation for Star Link light pollution), and for researchers to collaborate using multiple (production line) copies of the same high end instrument where 1 instrument might cost $1 billion, but 9 more might add only 10-20% to the final bill. Plus over time, implementing incremental improvements over older designs become a lot more viable.
With the cost of mid weight to heavy launches as low as Space-X has brought them, it makes sense to utilise economies of scale to put multiple copies of the same primary instrument into orbit for bulk science, or to keep continuous watch over a single target.
While astronomers would obviously like more than one JWST up there, budget realities mean they'd far rather future money be spent on developing the next generation of space telescope after JWST. Just as happened with Hubble, the science JWST is doing will quickly throw up questions that will need a new and better category of telescope to answer. Launch costs are just a few percent of the over cost of building, testing, and running a space telescope. The savings are simply not enough to commission a JWST clone.
Also, SpaceX is heavily subsidized through NASA contracts ($5.4 billion and counting) so the idea that they would be able to afford to donate launches is a nonstarter.
this is great. Naomi really whets the appetite for the feast to come
What is the giant, black, rock like structure shown near Europa on the scattered light image??
The Extremely Large Telescope and SKAO not long to go along with Webb make these years of observation the most exciting times of observation perhaps ever.
This is very information dense. My respect for the detail and knowledge.
I have seen many of the" talks " at this channel but as a non-scientific educated and non native English speaker I have difficulty with the presentation in this vid.
Great Post. Thanks.
A most excellent and interesting informative presentation, it was a pleasure watching this, learning about our solar system, especially Uranus and Neptune, as one seldom hears much about these ice giants, maybe someday we’ll develop the spacecraft to which will noble us to visit the planets and moons in our solar system, if we don’t destroy ourself first….Thank you!
Thank you for this presentation. Perhaps you have met or heard of my brother-in-law at your new workplace. I believe he is involved with the scheduling of JWST, although I am not 100% sure. (Forgive my memory, it was at my Moms funeral in March and it was, is, a blur). I am so excited to see what humanity is about to discover.
Truly Amazing Thank You
The beautiful images of our universe are great but I'm much more excited for pictures of our solar system.... the place that we could actually explore in my lifetime.
Good content . Thanks Naomi
man it just gets better & better. those spectral cubes. oh man. gimme. gimme gimme!
Excellent, thank you
Where are the gigapixel-sized images for download? I can't find them easily. Thank you!
Amazing high density content of amazing science.
wonderful.. thankyou
This is all very very interesting, but "for Uranus we have a lot more activity than we have on the other side" kinda caught me off guard x2 43:33 😂
Thank you for this beautiful talk.
Very nice program to measure the space rocks.
The question is what in between two neighbor planets or stars and between east and west.
May be we will have to accept the invisible
Wow that telescope is amazing.
Good Coverage, Howard University is lucky to have you. It is a gem in an otherwise dismal city. I can't wait to hear what you learn about the Ice Giants!
yes, uranus is MY favorite too :) Looks super-hot in the infrared spectrum!
Thank you!
Looking forward to seeing objects from the Arp Catalog.
Thank you.very much.
Good content, bad audio.
RI the compression of the audio via the chat software is a problem of this video. Please have presenters record locally to address this issue.
Excellent presentation, Naimi. I will read the JWST website in a different light (excuse the pun).
Gwarn, Dr Rowe-Gurney!
Great talk niomi
There are galaxies shown where there is intense illumination at the center and it goes on for millions of light years in all directions. I imagine that humanity would face quite a challenge trying to live with a profuse number of suns shining 24/7.
Why not look into Andromeda galaxy and continue to zoom in and refocus all the way to surface of a planet instead of light-years past it? Can we get started on that? And Pegus V?
Err not how any of this works. An exoplanet will only be a single pixel on JWST. Best you can do.
@@byrnemeister2008 yes! Let's get started on a telescope that is capable of it! It would be a microscope and a telescope in one. I bet AI could figure it out 😆
Lyman Spitzer (passed on) is the cousin of Suzanne Spitzer Robinson (my lifetime friend - also passed on at 97 years of age) - Mary Rose Krijgsman - Island of Hawai'i
I didn't think it was optically possible for the Webb telescope to actually focus on such close planets. Just shows how really vast interplanetary distances are never mind the distances between stars.
It's all focused at infinity. The main issues, as mentioned in the video were always to do with ability to track moving objects and making sure not to blind instruments by pointing at something too bright.
Awesome!!!!!
Minute 24: Mars sand storms covering the planet. I take it that the Rover is still standing up, operating and using its technology and Pristine clean?
Small correction: Apart from the Moon, Mars is not always our closest neighbour. Venus can be millions of kilometres closer to us..
Not quite as exciting as the first moon landing but interesting by itself! Of the two outer planets, my favorite of the two is Neptune, mainly because it its beautiful blue color, my favorite. One of my favorite things about Neptune is its winds, the fastest in the solar system. And, of course, why is Uranus tilted like it is?
The best thing…The potential of this beautiful bit of kit is only just being realised.
The best and most exciting science is that which is going to be factual and established rather than mostly guesswork. Local is sexy.
Methane is not why out atmosphere is blue. Our atmosphere contains 0.00017% methane. Our sky is blue because of rayleigh scattering primarily in oxygen and nitrogen but it has more to do with path length
Great presentation. Shame on RI for publishing so late.
my desktop background also :)
I hope Dr Naomi spends sometime teaching, she explains really well and in a entertaining way
Is JWST sensitive enough to capture the heat signature of the "ninth planet", Planet X under hunting, that is responsible for tucking several of the KBO objects together?
NGC 3324 is in the Gabriela Nebula not the Corina Nebula
How do we adjust focus remotely from here on earth..??!!
thanks
Hi, here from Brazil...
I still can’t fathom why this telescope wasn’t called JWiST (James Webb INFRARED Space Telescope) so we can reduce it to 2 syllables instead of an awkward 6 syllables trying to say “jay dubble yew ess tee” or “James Web Space Telescope.” It could have been “jaywist” - as friendly and easy as “hubble.”
Just call it Webb if it bothers you
If you really want to call it JWiST, I'm sure nobody will mind. Some people might think that you're a bit strange, but they'll probably be polite enough to not mention it.
@@ShadowWizard123 It will likely, naturally shorten to "Webb" or "James Webb" over the years. Most say "Hubble" now without adding "Space Telescope" and the assumption defaults to the telescope now. What I can't fathom is that agencies like NASA are almost pathological about making acronyms and backronyms to the point of making us roll our eyes in how hard they forced it and here was an easy, no-brainer they left lying on the table. 😊
Try telling that to the LGBTQIA*+- folks
Webb hope: more info on how the solar system travels through the milky way galaxy and bops into climate change cycles (about 1 degree per climate change cycle? -- a lay person alert) Since the Webb telescope includes infrared it can see through stellar dust to see what the solar system is really dealing with in its milky way neighborhood
what "light" source causes the "shadows" (14:55)?
Bedankt voor het verhaal. 🇳🇱🇳🇱🇳🇱Ik kon een deel van het verhaal volgen terwijl ik lag te slapen. Buiten is het +_35*Celsius hier in Oostelijk Centraal Europa. Groeten.
Does the JWST always point its lens away from the sun?
Why are we not looking at all the big planets through Web?
Could an untimely supernova blind/damage JWST?
It would have to be very close and we're fairly confident that there are no stars likely to produce a supernova within 50 light years. Our solar system is located in a thinly populated part of the galaxy.
@@alangarland8571 I think Betelgeuse at 550 LY is the closest. BUT the year I was taught that was 30 years ago. So I could be dated by now.
I can see my Home from here!
