đ©đœâđ» I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

Shoutout to my supervisor Don for creating WASP and to my friend Evie for writing the NIRCam paper đ€©. I'm so proud :)
Awesome!
Hell yeah!! Incredible!!!
Your supervisor created a star?!? Impressive.
@@ZeroAlligator WASP is the Wide Angle Search for Planets. WASP-39 is the host star of the planet WASP-39b.
Your supervisor, Don, wouldn't happen to be Don Lincoln, would he?
Science can explain everything. Except how motorbikes can move despite converting 100% of their energy into noise.
i dont think they do move - i think everything else just runs away
The guy driving up and down my street at night , is really testing that idea out .đ€
Vibration is wondrous.
fuel to noise converters
noise so loud it pushes the bike
We are in a golden age of science communication. Even sixteen years ago, there were just a handful of public science personalities. Now, we (or - more importantly - kids) can search for this content with ease and get an abundance of results. But none of that would be possible without people like Dr. Becky actually producing and publishing that content. So, thank you, Dr. Becky and all ScienceTube/EduTube creators!
I'm thinking back to some of the blogs I used to follow back in 2006. You're right - there is quite a good amount of content related to this around today.
Science has replaced religion, its more of a cult than anything.
@@jesslove1181 oh shut up
Yes but what worries me is yt is also full of a bunch of BS science for lack of a better word. With catchier clickbait titles and fun computer generated images. The access is great but it's really unfortunate that people, especially kids, won't be able to tell the difference between real science and the fake stuff.
as an adult channels like these are also invaluable to keeping me up to date on the current understanding of the world, and also helping to (very slowly) chip away at some of the oversimplifications and misinformation that were taught as hard fact in grade school.
I was telling my brother and sister-in-law about this the other day, and they didn't believe me at first. I had to explain to them how it worked. It is pretty amazing what we are capable of. My grandmother used to tell me about their horse and buggy when she was a kid and when she saw her first car. We have come a long way.
My grandfather would tell the same story about the first motorcar in his town.
It really is amazing how far and fast we progressed. My grandfather was born in 1898, so he saw horses transition to cars, telephone and electricity, radio, television, penicillin, first airplanes, first jets, first rockets-and just before he died he watched people walking on the moon. Live, on TV.
đđđ±
That's a testament to what makes humanity, for the most part, a pretty cool thing.
@@tiafolla have we really âprogressedâ?
When I was at primary school in the '60's, one of my favourite books to take out of the school library was a book on the solar system, but pretty much every planet either had very blurry photos, or 'artists impressions' of what they might look like. Fast forward to 2022, and we are analysing the atmospheres of planets 700 lightyears away - how amazing is that!
BTW, at 64 years of age, I am REALLY hoping that before I kick the bucket unequivocal evidence is found for present or past life either in the solar system or on one of these exoplanets - so get to it you lot! đ
90âs here and it was probably the same frigging book for some reason đđđđ
But regardless of how old it was at the time it sparked a amazing lifelong love and awe to all things science
So cool you had Jake on, itâs amazing when the researchers chime in on things like this
Dr. Taylor reminds me of Sir Magnus Pike with the way he expresses himself with his hands.
@@Beer_Dad1975 Super crreeeepy.
We definately need more Dr Jake content. The dudes enthusiasm is awesome, he knows his shit, and he's right on the coalfront. Awesome
I think it's really important for the researchers who work on something to have the opportunity to address the public directly. Yeah, okay, papers are (sometimes) freely available for anyone to read, but academic work can be really difficult for most people to understand. There's lots of complex math, technical jargon, and mostly extremely complex ideas that all depends on each other. When the person who does the science breaks their work down into language that "regular" people can understand, suddenly the work doesn't seem pointless or ridiculous. I've seen what the public says about a lot of the work done and most of it is not good; because they don't understand it and why it's important and how it impacts us. When the unreachable is all of a sudden within reach, the entire field of science opens up. I firmly believe this is how the process should work. Do the science, then show the science in a way that everyone can get it.
I really appreciate your enthusiasm and delivery as a science communicator. It's pitched higher then everyday science but you take the time to bring us all up to that higher point with clarity and respect - thank you so much for what you do
She's definitely one of the best! We're very lucky to have her.
Thank you for such kind words!
Hard agree!
This was a really good episode. We, Astronomy buffs, are so lucky to have you. Thank you for all you do.
Oh, and the bloopers were fabulous. đ
Hi there Dr Becky, being an astronomer I wondered if you could explain why it is that the VATICAN owns all of the worlds astronomical telescopes? This is a serious question, thanks! ;D
I absolutely love that you share your knowledge and enthusiasm with the rest of us on CZcams. I have always had a layman's interest in astronomy and astrophysics, and your excitement in sharing boosts that.
Parents! Please take note of the MEL Science kits. As a child I would have loved this. I know because one of my favourite ever presents was a Chemistry set. Thanks Dr Becky for promoting this.
I thought was a really cool bit as well and I don't even have kids!!
It's hard not to be into the science while looking at your expression when you discuss it. What a fantastic ambassador to astronomy!
Yeah I'm sure many folk have placed their little ones in front of the computer to see enthusiastic Dr becky videos. Aboutt 30 parents from the UK. thousands globally.
It cost nothing if you already have the Internet. Parents with little to nothing should do so. Alas looking like a goldfish and following folk who already have sprouted their fins to show of their lips in an goldfish bowl is probably more important.
@@jeddaniels2283 you ok?
You should try being one of the good meaning but easily swayed people that watch the BS on tiktok about ufo flying aliems and giant sasqrotch and how Tesla invented pyramids and electricity and then a time machine and then he went back in time to teach the egyptians how to use electricity but then Edison appeared too and they fought and Edison won. That's the REAL reason why Edison is the purported inventor of magnets and xrays. Tesla was framed by Ra.
Oh please.
Cheese factor ..... 10.9 !
I'm so glad this randomly came up in my recs. You and your colleague made astrophysics feel so warm and exciting - which it IS! Science is human potential shining brightly and good science communicators are so needed to get that across.
Going to listen to the A Cappella Science exoplanets song again to celebrate.
Love the lanyards!
Itâs crazy to me that a planet can be that close to a star and not have its atmosphere completely boil and blow off.
i remember being explicitly taught in grade school that only rocky planets orbited close to stars. this video casually dispelling that lesson is rocking me.
Yeah it is crazy how much we have learned about solar system formation over the past 10esh years.
@@58209They weâre probably talking about our solar system which is correct. We barely knew anything about exo planets until the late 90s
@@58209 I remember, as an 8 year old child, asking my Science teacher a question, to which he replied 'That's a very good question.' He then waffled for a bit without really enlightening me. I remember walking home from school thinking 'Wow ! I asked my science teacher a really good question.' It was only years later that i realised (English spelling) that the phrase he used was a ploy that adults use to give them thinking time to answer the question.
@@58209 the models are always ideal/perfect in the absence of data...
I love your (and Dr Jake's) work. You both explained this topic really well to us mortals. Thanks
Thanks, Dr Becky, for bringing these results (and Jake) together into such a brilliant presentation!
I told my my 94 year old dad that I'd report any discoveries from the JWST because it was bound to expand our understanding of many things in many ways. Mom passed away in 2020 and dad was always a science nut. He doesn't know what to do with his life now that she's gone, so I'm hoping a lot of planetary and cosmological discoveries will come in whatever time he has left and he stays sharp enough to take some wonder and delight in that knowledge. I want longevity as a personal goal because I always want to know what's next, and we seem to be in an age where astonishing discoveries are being made around every corner we turn. I know it will make his final moments deeply meaningful. To gaze at the wonders of the universe up to the very last breath, I feel, is to become a wonder of the universe yourself. This is the first thing I can really sink my teeth into. Thanks for breaking this news. It means a lot not just to science, but personally to many people. When my dad was young he was ridiculed for thinking life could exist on other planets and that rockets could accelerate without an atmosphere to thrust against.
You're lucky Fauci didn't kill him.
@@KenJackson_US Dad had covid-19 twice and the first time it didn't even make him sick.
Amazing stuff! Thank your Dr. Becky and Dr. Taylor.
All these discoveries and precision data gathering in only the first 6 months! Incredible.
At this rate, we're going to need an annual recap of all the revolutionary discoveries the JWST has made.
One of my favourite episodes so far, you seem even more excited than usual (which is already a lot!), do a great job of breaking down the chemistry process to make SO2, love the guest interview as well. Yay Dr Becky!
I'm REALLY happy he mentioned GJ1214B! That's my favorite exoplanet!
You are doing such a great job explaining everything here.
Truly entertaining.
That was truly a fascinating presentation yours followed by your interview with Jake Taylor. This is really cutting edge planetary science. The only thing I would like to see is MORE, MORE, MORE!!!! Your the best Becky!!
Dr. Becky, I saw what you did !! You gave a very excellent introduction and provided the tools and concepts before you played your guest. That aspect, the prequel, was brilliant and truly, I got a lot from your guest because you gave both the context and the science so I truly appreciated the discovery of the SO2 bump for example. Thank you
Becky my grandson and I watch you together 7
years old ,great job with infectious enthusiasm .We love you. This he understands and thank you
First time I am actually intrigued by the sponsor! Good on you Mel Science. I like the initiative for promoting scientific literacy at a young age
As always a fascinating discussion as always. Thanks to you and all your colleagues.
I'm very glad I found your channel earlier this year. This is some really cool science, really well explained.
Thank you, Jake!
Man, this is SO cool!!! đ€©
We all Love your way of making Astrophysics interesting, and exciting. For this old man in Texas, I am proud to find that some young people are happily doing things that are worth doing. Now if we could get Dr. Becky to play her Ukuleles for us, that would just be fantastic.
I love the enthusiasm you bring to your streams m8. Making learning fun is so much more effective than dreary lessons.
Amazing video thank you and for the interview.
Thanks Dr.Becky! You always bring exciting news!
đđ..
Absolutely LUV the genuine enthusiasm that you bring to your explanations for this science geek!!! Don't ever stop!!! đđđ
Webb just constantly blows me away with what new science it's bringing us! Thank you, Dr. Becky, for all you do!
It's like Voyager 2 in the 80s and 90s, except the data's coming in a lot faster because JWST only has to turn a bit where Voyager 2 had to travel for years between each batch of encounters.
Awesome info!!
Also, thanks for mentioning the link has no paywall. Always good to know!
wow becky, I haven't stopped by your channel since around when you made it. You've been killing it with these videos! great job
YESSSSSSSSS!!!!! I've been following the exoplanet studies as best i can since before the launch of JWST because i knew they would find something interesting. i'm glad i caught this video because it's hard for me to find relevant information about exoplanets, and i haven't had the time lately to comb through everything. i knew we would find SOMETHING
I just love listening to true experts ⊠especially, when there is such a genuine excitement as the subject is being discussed ⊠goes for both of you ! Thank you for sharing â€
lovin the regular uploads Dr.
keep em coming please
Big up Dr Becks
This is incredibly exciting! Thanks for this video!
An insanely interesting and awesome video Dr, loved it. The JWST is going to show us things we never could have imagined. It's a great tool to help along disclosure.
Keep it up, great work.
I love this. Looking at earth-like planets in different stages of their developement is like looking through the time of our own little blue spheređ„°
mind absolutely blown im so excited for yall to find o zones
Incredibly enthusiastic and very well explained (with graphics, and a very well created 'background' that's there to process: PhD, author on Black Holes, JWST sweatshirt, wonderful persona and personal appearance) presentation. Thank you for helping to make Science understandable to more people. Knowledge is Power to make more informed decisions. đ
I always love hearing experts (read: nerds) talk excitedly about their field of study. Thank you for sharing your enthusiasm with us Doctors Becky and Jake:)
Thank you Dr. Becky for creating such a wonderful content about astronomy.
Loved the way Dr. Jake described the eureka moment, I got chills!
Not just a doctor of astrophysics and an ace CZcamsr, but a ukulele player too. Some people know no limits.
Wow you and Jake are both excellent orators. It was really cool to learn more about this.
Truly appreciate your energy and candor. Brilliant.
Hey, doctor! Thanks for making this stuff so accessible for us lay-people. I really appreciate it.
@Tech
"Dude" ? đđ lol đ€Ł
The only uptick the four of you received was.. Wait for it. I'm dying.
We need more Dr Jake. He's great. Also, studying Trapist is friggin cool. That things got my attention as an amateur astrophotographer (Not that my baby rig can do Trapist, but its fascinating me......)
This is so amazing, Thank you Dr.Becky. I'm sharing with all my friends.
I recently checked you out on the sixty symbols channel. CZcams now recommended this video and... yeah you got another subscriber. congrats, this is very nice information, very clear and concise.
Oh I am obsessed with Dr Jake! He needs his own channel!
He posts a lot on TikTok if you want to check him out there - I linked his profile in the video description đ
Jake is wonderful! The passion is infectious - can't wait to see the new results for Trappist
Ant water vapour found in the Trappist system is down to the monks!

I'm pretty sure she's a she.
@@karlbush89 I was talking about her guest ie Jake Taylor although in fairness Dr Becky shares the same passion so I should have made my comment clearer, sorry.
At first I wasn't too excited - but after watching the whole video, and especially when watching the interview with Dr. Jake Taylor, I was infected by his excitement. Very well done!
It was the same for me. The fact that star light can trigger chemistry in exoplanet's athmosphere did not seem exiting to me. When it make it in our Sun's planets it can for sure do it in others. But I know Dr. Becky for her exelent videos so I clicked on this one and wasn't disappointed. And the interview with Dr. Jake Taylor as someone who is exited about planets was really not only very informative, but also amazingly exiting.
I got super excited just reading the title, since i confused photochemistry and photosynthesis and thought holy shit . Still a very cool discovery.
@@daftwulli6145 It is a cool discovery. I also thought at first "photosynthesis", but reading the title a second time I was less excited. On the other hand - the kind of photochemistry is interesting, as it differs from Earth, and I think that is what excites Dr. Taylor. Well, finding oxygen in larger amounts around an exoplanet would excite even Dr. Taylor more, I guess. đ
@@c.augustin yea of course i absolutely agree, but i mean photosynthesis would be basically proving life on another planet, which is a whole new level of cool. DonÂŽt get me wrong it is still cool and mindboggling, but not on the level of one of the most important discoveries in human history
@@daftwulli6145 Yeah, we're both on the same page there. Not likely that JWST will find oxygen in the atmosphere of an exoplanet, but who knows. And JWST should not be the last telescope of this kind (I hope that the plans go through).
I don't think it's gets any more cutting edge than this. Thanks Dr. Becky.
Bravo, Bravoo!
i feel a bright future ahead
This is so great đ
As a kid I wanted to be an astrophysicist. Alas due to (in hindsight) a disability resulting in a burnout at 15 I didn't get to go to university in the end. I really like to see the field from the side though đ
What disability?
First thought: if Dr Becky says a new scientific discovery is a big deal, then I believe her.
Second thought: ALL new scientific discovery is a big deal!
Thank you, Jake! And you, Dr. Becky! đ
What a great explanation! Thank you as always!!
Just for fun, I got the mass of the start based on the numbers that Dr Becky provides and it's almost identical to the mass of the Sun, like crazy close and she did not give us precise numbers. Once you get the mass of the star (approx) one could try to find the mas of the planet based on the doppler effect for example. The question is on the assumptions they do to calculate the distance, or if they assume the mas of the start and then get the rest of the info using that.
Im really considering do another masters in astrochemistry. I have a degree in analytical chemistry and a masters in public health. But Iâm so so intrigued with the JWST discoveries and have actually be reading astrophysics. The âspecâ JWST are just incredible. Any advice from anyone! Great video. Iâm in love with your content.
I have some advice. Instead of dedicating your life to absorbing other peoples work, why don't you use your knowledge to making new discoveries? Get into actual research where the real work is done.
@@MrBottlecapBill but carrying kn other peoples work is literally the basis of humanity. Adding to the existing pool of knowledge is surely still as ânobleâ as doing my own research. Also, plot twist, Iâm not Bruce WayneâŠâŠwhere am o going to get money for my own research. Ido appreciate the advice though. There should always be a healthly portion of what you said in anyone I think.
Go for it! Quench your thirst
The glee with which he said TRAPPIST!! Iâm so excited
I love how excited Dr JT got about observing Trappist , he was very interesting to hear from đ
I will probably not be alive when we find proof of extrasolar life, but every discovery makes me more and more confident that it *will* happen one day. We really need to get on the whole warp drive thing so we can be ready to visit it! đ
This is awesome stuff!
I feel like we should be building 4 more JWSTs and getting them out there to accelerate this science! Maybe in a few other LaGrange points?
Bahahaha! Have you seen the price tag on that thing? Ain't gonna happen. even for Christmas.
The Carl Sagan visible spectrum telescope project has begun & last I heard they were targeting 2033 for launch. I forget which Le Grange.
@@jamesengland7461 the sad thing is that that is so very very little money at this scale. And I imagine they could build a second cheaper as theyâve already done all the r&d
Why do that when we could spend all our money blowing up brown kids.
The US anyways.
The Lagrange points are single points mathematically but in reality are huge regions of space, you could put thousands of telescopes in any of them (far more than that really). The leading or trailing points (L4 and L5) are most likely for observatories that need to be able to see the entire sky at any point in time. L2 is handy for things that can't be allowed to see the Sun, but it has the issue of having Earth fairly close by, blocking a chunk of the sky.
this is why even as a grade school student when the teacher stated something, I questioned what was taught. I remember as a child looking at a map and seeing how the continents looked like a giant Puzzle that could be placed together as one. Continental Drift was not even accepted in the early to mid 60's. I remember being admonished by my science teacher for even talking about something that now is accepted as something that actually happens. Now we accept that Pangea once existed. So, I learned to question everything and everyone that told me anything including Education, Religion, Parents. I remember my dad one day telling me that his discs in his back were bad and in the same breath telling me that he wanted to get another Horse. I asked why and he said to ride. so, I thought about his statement about how bad his back was back in his face and asked him why he wanted to go bouncing on a horse's back. you could actually see the light click on in his eyes.
Love your science (and your ukuleles on the wall). Thanks
Not so unexpected that we've found SO2 in an exoplanet's atmosphere, but very cool to have it confirmed that JWST is capable of doing some of what it was built to do. If any exoplanet were going to have observable photochemistry, WASp-39b sure is it.
This has been a BIG year for Space & Various Discovery. Lets be honest! This is... Rad!
Thanks Dr. Becky for this content, it truly is awesome!
Hi Dr. Becky. Just got my laptop back from repair and they have replaced the HD and now I've got to find and reset everything!
But I've received my long-sleeved Dr Becky pullover and your book! Thanks!
Being that close to the star, how is the planet retaining its atmosphere from being stripped away by the solar wind? Wouldnât there have to be a large magnetic field to deflect it?
Unless Iâm mistaken the planet is a gas giant.
I am 40 years old but I totally do wanna do that mel science thing i still love science lol - i actually asked them is it also for adults and they said yes totally lol
Science is for everyone.
It's all about wonder, sparking the imagination and dreaming the dream.
Forget what it's labelled as and order the kit. Spark your imagination and the ideas you come up with will be further than many scientists will go.
Thank you both :)
I just read about this in a Norwegian science magazine. Light that passes through a planet's atmosphere, revealing it's content.
Dr. Jake is nearly as enthusiastic as Dr. Becky!
Astrophysics must be the best job ever, with such enthusiastic people working in it đ
I love your channel so much!
That little song at the end was my everything.đ€Łđ„° I also love the whiteboard in Dr. Taylor's room with all the formulae on it and "Yup!" with the arrow pointing to the diagram in the corner. Also: his "Mission Mars, Disks 1-4" on the shelf on the wall... It's the little details that grab me.
Super news and fabulous info. Well presented. Easy to understand.
thank you for this information. And I am looking forward to your next video.
First of all thanks for all your videos they are super informative and interesting. But also when are you dropping out the Asto album, always enjoy the lovely singing at the end.
Thanks for the great video : )
Exciting stuff!
I love things like this because if you just told me there's sulfur dioxide in a planet's atmosphere, I'd be like "so...?" but a thorough explanation like this has me so excited!
Thank you very much. For twenty minutes it made me feel what an exciting time this is to be alive, and I could momentarily forget about the worrying state of our own atmosphere.
And I like your and Jake's spectroscopy lanyards (not yet banned by FIFA so far as I know).
Very exciting đ. Bought your latest book A brief history of black holes. I enjoyed it very much đ. Cheers for all you do Becky and have a lovely Christmas.đ
Jake really conveyed how exiting this is!
exciting discovery. Love your enthusiasm for space and exoplanet's. Subscribed.
Great to see the camaraderie in these scientistsâŁ
The Mel Science Experiment kit looks pretty neat actually. I approve of this. Wonderful, and relevant for learning complex behavior of planet surfaces among other things in a fun way.
Love Jake's enthusiasm!
Really loved this! The byte about us not knowing how our gas giants formed is really interesting - would have enjoyed to hear Jake talk more about that.
If I am remembering correctly, we used to think that young stars blow all lighter elements outward (asteroid belt and further) due to their solar wind, where they coallesed around planetoids to form gas giants and ice giants. Then when we discovered the first exoplanets with "hot jupiters" gas giants closer to the sun than mercury they tried to adapt that theory with planetary migration but it didn't fit well enough as some extremely old stars and young ones still have hit jupiters regardless of age. Now we are back to having no real perfect answer, from my understanding. Hopefully someone more well versed to n this can answer
