👩🏽💻 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.

Who *wouldn't* want a whole video on the Yarkovsky effect?
On that point, I was a little disappointed that she didn't mention that the Yarkovsky effect confirmed and refined by studying Benu was central to the updated calculations telling us that Benu has a non-trivial chance of hitting earth in a bit more than 150 years.
I was going to add: “complete with ear worm tunes I hope,” but I saw your response and 🥺
@@TrabberShircuz that would be fear mongering for no reason, especially since 150 years is far enough in the future where we'll either be able to do something about it, or we wont be able to because we already fracked ourselves some other (much more likely) way.
Not sure maybe Yarkovsky is not interested
lol
@@TrabberShirwell that will gives us a pretty big sample.
I'm just fangirling hearing Dr. Becky talk about missions I've been a part of! We (especially at Goddard) worked so freaking hard on this broadcast and all of the animations to go along with it. Thanks for covering it!
🖖😃 Thank you for your science service!
👏👏👏👏👏
It was a very enjoyable broadcast, you guys did a good job!
That's my brilliant engineer niece hopping for joy in the background at 0:06.🙂
Fantastic
This is cool. I love that Jaxa, Esa, and NASA share the samples. It's a fantastic collaboration in the pursuit of science.
i feel like collaboratoin is a huge part of research and academic pursuits. I never graduated my first 4 years of college, so I may have no idea!
I completely agree with you, by the way :)
It is, but it would also be nice if she mentioned the others who are receiving samples due to their contributions to the mission. She seems to have a blind spot to some countries where it is about science or her book release.
Yes, I am interested in learning more about the Yarkovsky Effect. I'm in awe that the Earth acquired its water from external sources, that it has managed to retain its water, and that the Earth has not been rendered uninhabitable by asteroids. While the Earth could be easily made uninhabitable by humans, that it exists at all as a place where carbon-based life flourishes fascinates me.
more detailed Dr. Becky science videos? yes I too would enjoy this. Someone say hour+ long? what? I'd take her classes if she taught this that's for sure. Love the work you do Dr.!
Life has rendered the Earth uninhabitable more than a few times as our oceans and atmosphere changed there composition. The first time was when Cyano Bacteria put O2 from the ocean into the atmosphere choking it self out. Then again with the grate dying. Then another time as O2 diminished and large monster sized insects died off. If we make the Earth uninhabitable something will get threw the bottle neck and take over. The Earth wont die, and trust me the CO2 thing is greatly exaggerated. CO2 is NOT a runaway greenhouse gas. It can only raise the Earth temp by 2°F and most of that happened at the end of the last ice age. We will have to try something else to wreck the Earth. Hope you like eating Bugs because Methane is a runaway greenhouse gas.
Yarkovsky Effect is caused by the differential heating of one side of an object orbiting the sun. As the object spins, the warmer, Sun lit side rotates into the shadow side, and radiates photons (infra red photons) to a greater extent than the cold side, which has just rotated into the Sun lit side. This differential radiation of photons, imparts a minute momentum to the object, which over eons of continuous Yarkovsky Effect, can gradually change the objects orbit around the Sun
Humans have nowhere near the power to render the Earth uninhabitable.
@@sovereign1160 yep. Thats the real science.
o-Rex was so exciting! i worked on the parachute!!
Nice. Well done. 👍
At least you put the accelerometer in forward.
Thank you! I actually did a small whoop of relief when it deployed so perfectly!
hhahah you and my boss both!@@Ann-snowshoeingonEnceladus
Sometimes it boggles the mind, the complexity of these missions. Very exciting!
Yes it boggles the mind that much that it makes one wonder whether it's actually true 😉
Because you have no mind-you can't have a gas next to a Vacuum fake space without a container. Gas instantly would escape to fake space vacuum if no container.
I'm tapped out just putting together a grocery list.
having trouble coping switching from fantasy to real life?

I hope this doesn't come off too much as google-eyed fanboying, but I seriously think Becky is turning out to be one of the best science communicators since Tyson -- and minus the frustrating ego. I wouldn't ever ask her to stop doing the actual astrophysics that needs doing, but if I could just dream for a moment, I wouldn't hate it if someone gave her a documentary TV series or something. Maybe a collaboration with Brian Cox? (the physicist one, not the actor one). As the next American presidential election approaches, I'm going to need anything I can get to get me out of bed in the morning, and turning on actual TV isn't going to do it. I'm really glad Becky's here.
Fun fact: Both Dr. Becky and Prof Cox are from (Greater) Manchester. Dr. B from Bolton, I believe. Prof Cox from Oldham. I used to live near Bolton. Never been to Oldham.
Further fun fact: This proves that Manchester has been the centre of the universe since the industrial revolution!
ETA further fun fact: Manchester boasts the best football team in the world - Manchester City. As well as some other team that plays in red, over the Irwell. I forget their name.
Tyson isn't all that good.
@@ianw5024 Well, there's a MILD chance that Ptolemy, Copernicus, Galileo, Kepler, Newton, Haley, Messier, Herschel, Drake, Einstein, Sagan and Hawking might have a few things to say about that, but NONE of them would dispute the awe-inspiring wonder that is Manchester football. If football had a mathematical enigma that it needed to call "dark matter" because it didn't know what to do with itself, then it would be called Manchester.
Agreeded
I watched the landing/recovery and am just amazed at the complexity of and detail in all the calculations and planning that goes into these missions. Reminded me of all the steps in the unfolding of JWST that had to go just right. Thanks for the summary of the mission and the teasers for what's ahead with the samples. Another "YES" for for more on the Yarkovsky Effect, please.
Absolutely true science at its best
I know I've said it before, and I know you have your little studio dedicated to this, but your vids shot in this particular room are always better. Must be the lighting or something. Just feels more welcoming. 🙂
Yes, I saw the footage of it landing actually. Looking forward to the results! 👍
Watched the landing live; what a relief when the parachute opened!! The sound of disappointment from the crowd when Genesis crash landed in 2004 was just so sad.
NASA also did a very nice video montage about my home state where both samples landed, so that was pretty cool.
Looking forward to updates around mid-October and yes, a video on the Yarkovsky Effect would be awesome, especially if there's a song in the bloopers. :)
Can we take a moment to acknowledge the greatness of the good Doctor's comfort level in this video? She makes me wanna grab a quick mug of hot chocolate and cozy up with a blanket around me and binge some astronomy vids. 😅
Lest we forget, there has also been a sample return mission to a comet. The Stardust spacecraft sampled dust from the coma of comet Wild-2 in 2004, and returned the samples to Earth in 2006.
Also, the Philae lander, part of the Rosetta mission to comet 67P (2014-2016), was a short lived laboratory on the surface of that comet. And some of the dust ejected from the comet was captured and analysed by the mother craft. Lots of organics. In fact, comets are covered in them.
However, the D/H ratio of the water at that comet, and from most others that have been measured, are quite different from terrestrial values. Hence why it is thought that the bulk of the Earth's water may have come from asteroids. In particular, C- type asteroids, which have similar D/H ratios to Earth.
When earth was created it was a sphere of water, then the land was brought forth from that sphere of water to form the one whole continent in one 24 hour day. Be careful where of you speak for you were not here when it was formed so you are incorrect. I know the creator of this planet, obviously you do not.
ESA does a lot of good work worthy of more attention. I wish they would get a crewed program going.
@@robloggia Indeed. Funding is the problem.
I remember watching the pictures from the Giotto probe as it approached comet Halley in 1986. That was ESA. The USSR sent a couple of probes (Vega I & II) and the Japanese sent a couple. Zilch from NASA.
ESA does some brilliant science. I know some of the people still working on things there. Venus Express was another ESA mission. A former colleague wrote some decent stuff on the plasma environment there. As he also did with the Rosetta mission. Plasma physics rocks! (but only to plasma physics geeks).
So I was out in the area when it landed. We heard a boom but I have no clue if it was this thing coming into the atmosphere. Got stopped by some rangers and feds on our way out 😅. Had no idea why they were blocking the roads and forgot this was happening. Just happened to be out there for an unrelated reason haha.
The OSIRIS-REx mission to the asteroid Bennu and back to Earth is totally mindboggling! Can't wait to see what they find out after analyzing the sample! 👍👍💥💥
You mean you actually think this is true?
@@PeterPeteOf course it’s true, why do you doubt it?
@@radart6037 You can't prove it's true. Nobody can verify any of the information given by NASA to support this mission. Dr Becky's science doesn't do truth or proof 👍
They will find nothing as usual
It was so nice to see you on the tv the other night talking to Tim Peaks talking about Black holes.
You are so skilled at delivering detailed information in a easily understandable manner. Your videos always make me feel interested and engaged, regardless of the topic.
Learned more from your video than watching 3 hours live when the sample returned. Thank you as always!
I’d love to hear more about the Yarkovsky effect. Love the science you bring us.
Thanks for covering the mission Dr Becky 😀
It is so refreshing to listen to someone who actually knows what they are talking about! Keep up the great work.
Exciting news in astronomy. Thanks for the video Dr. Becky.
As always, dr. Becky delivers a terrific video on a very interesting subject. THANK YOU! As many others, I'd love to see a video on the Yarkovsky effect.
I was so excited waiting for your report and a great report it is! Your summary is very complete, thank you for taking the time to put this together.
It was also fun to see your fingernails match your tea or coffee mug. You think of everything! 😊
No shit? Wow I forgot all about this. Nice, Thank you for reminding me. This was the one that collected so much material that they had trouble closing the container. This is so exiting. OMG did you really just sing that? hahaha
Yes to the Yakovski effect video! Yes to the flowers and home setting for this video! Yes to your nail color choice and yes, to your tea mug! ❤ it all! And Thank you for your clarity and the trustworthy coverage of Osiris- REx 😊
Yet another superb video..thank you Dr. Becky.
I was hoping Dr Becky was going to do a vid on this. The tech and the brain power of the people who are responsible for doing this stuff is mind blowing. I am looking forward to the results it is smart they put samples away for when our tech improves Thanks for explaining the possibilities and hopes of the scientists.
I want a whole episode on the snow line. This is the first time I have heard about.
Video on Yarkovsky Effect, yes please 😁. Anything on orbital mechanics is welcome 😍🙏
Can you make another video with other exciting tests that will be performed on the samples? And yes, a video on the Yarkovsky Effect.
Dr. Becky!! I just wanna say how much I love your videos! I wish I could express how much I appreciate what you do. If it wasn't for people like you, I never would have realized my love for learning or discovered my deep interest in the physics of our universe. Ugh I could go on and on, but a UA-cam comment thread probably isn't the appropriate place for it. 😅 I was wondering if you have signed copies of your book available for purchase and if so, would you kindly point me in the right direction? Also, I have a crush on you for real 😍😍 a thousand apologies if there is a Mr. Dr. Becky.
Dr. Thank you for your patience, and your informed education that you share with us. Ty
your excitement is contagious...water origin always fascinated me as well.
Teach us everything, Becky.
Will testing the samples show if Bennu is a rubble pile better than the way the sample arm plunged into the asteroid?😊
Depends, how massive it is will determine the matrix distribution of the aggregate and whether it metamorphoses into a solid core...
I love the science content and the bloopers are a perfect cherry on top 😊
I love your enthusiasm when you're presenting your videos.
:) Little editing mistake at 1:36, you've overlain the video of re-entry over the video of launch. Still love your videos Dr. Becky!
Little by little, we're getting there. I halfway believe our tech might save us from ourselves.
how does a few grams of space pebbles save us?
@@br.m I was thinking the ability to get them might save us. The grams themselves might be interesting too.
@@alextilton2677 Space rocks are definitely interesting but I can't imagine how it might save us.
Unless we discover gold or lithium or things and can stop destroying Earth to get those resources. That still won't save us but it might save the environment and wildlife. Only Jesus can save us that's how bad we are
I remember this. It's a remake of an old classic. Even the reentry capsule is the same. What was it called... The Andromeda Strain. That's it, The Andromeda Strain!
Well nice knowing ya.
Ahh yes, all those highly accurate Hollywood science documentary movies! ... oh ... umm ... wait a second ...🙃
Yes please, we (and Prof./Dr./Ms./Mr Yarkovski, probably) would be incredibly grateful to have a vid. about the aforementioned Effect 🤞🤞
Not First!
Congrats 🎉
😂👏
First?!
Winner 🎉
Fantastic video and was absolutely blow away when you mentioned size of the asteroid! To think we can plan to hit what's bloody minuscule target in the grand scheme of things is just awesome :)
I also love your enthusiasm for it, the excitement really shows :D
Your enthusiasm for your work is enchanting! As a fellow Lancashire native I love watching your videos. As an astronomy nerd too.
What an exciting mission - never thought we would see the routine return of samples like this! Very cool!
This is such a cozy video, with the tea and the blankets :)
Looking forward to more OSIRIS updates. Thank you 🙂
Great vid. As usual.
Also - I love your mug! Excellent taste.
Wonderful explanation as always, thank you. It's been a great mission really pushing the envelope, can't wait for the first results... and you clearly care about all the details: even your nails match your mug!
Yes, a video on Yarkovsky effect would be great!
First time watcher here. I almost clicked away. Thank you so much for being a real science channel. It’s really hard to find real channels and we need more of you. I am aware that I don’t know how to be successful on UA-cam, but seeing you… don’t give up. You’re great
Great explanation as usual. Thanks for the effort and preparation you do for these videos.
Soo cool, I love this stuff!! Thank you for sharing. ❤
Thanks for the in depth update Doc!
PLEASE! Please do a video(?) on the Yarkovsky Effect!! It sounds interesting (if a little complicated!). I LOVED this video, by the way.
Thanks for this early update about this incredible sample, and the incredible journey through earth labs that is now waiting for it !
This was a very fascinating episode! Thank you, Becky, for such an amazing delivery.
Thanks Dr S. Yarkovsky, yes pls.
Exciting times in science!
Also that flowchart 😍
Looking forward to it!
Now that's really interesting!
I am usually pretty well-informed on the topics to take up, but you always enlighten me more.
Thank you for sharing your mind-opening insight!
Another yes on the Yarkovsky Effect. These missions are so cool to imagine, my hat's off to the engineers and scientists who put this together. As someone who stood in my front yard as a small boy to watch, I think, Echo one pass overhead the fact that I'm now witnessing all this stuff is mind blowing.
Thanks a bunch for all the explanations, dr. Becky! 😊
Stay safe there with your family! 🖖😊
Always love the bloopers Dr. Becky 😀
This was great. Thanks.
Can't wait for the results!
I was looking forward to your video on Osiris Rex. I'm in favor of a deep dive on the subject.
Love yer stuff, Becks...
always enlightening and entertaining.
Blessings from Fife be upon ye !
Cool. Can't wait.
Super fun, Thanks, Doctor. Cheers from the Pacific West Coast of Canada.
I'm sorry but yes, I would love to hear the details of that effect. Your information is extremely informative and easy to understand for the rest of us, which is why this is such a good channel. Thank you very much!
One of my favorite Dr Becky videos in a while, would love to see one on the Yarkovsky effect! I donate my computer's spare CPU time to the Asteroids@home project which builds an open source database of all the known asteroids and figures out their spins. So I think Asteroids are super cool and love when you cover them :).
Brilliant as usual...
Absolutely brilliant
Your color sense is impressive, also informative vid, thx
An amazing mission, and a wonderful explanation by Dr Becky once again. Astrophysics seems to involve a lot of chemistry.
I almost fell from the chair when you said " I leave down the link just in case you want some LIGHT night time bed reading" LOoooooL
Thank you, Dr.!
I didn't know anything about this until today.
Absolutely LOVE that there's material reserved for future people and their tests. Really excited to see what we learn from this.
I highly recommend Dr Becky's back catalogue! Fascinating, mind boggling, fantastic info that is waaaaay better than any sc-fi novel, and mostly easy enough for anyone to understand! She's good
People of the future can get their own samples! /s
Fantastic video!
Great job doc!
Yarkovsky? Yes please. I'm a fairly technical guy, but I get lost in much of the astrophysics terminology and theories ... but you, Dr Becky explain them in a way that I understand. Thank you for that.
*_THE YARKOVSKY EFFECT:_** YES, PLEASE!!*
Thanks, Dr. Becky~
Nice video, I agree that the lighting is much better today
Another amazing accomplishment for science. NASA has a 13 minute video showing the process they used to collect the sample, which I thought was very interesting.
Pretty exciting science. Looking forward to seeing the results of all the tests.
Nicely done
Here for the science. Never watch bloopers as a rule. This channel is an exception. Dr. Becky's bloopers are quite funny and entertaining. As we say in America's deep south, "She's a hoot."
As well as excellent content, I love that mug!
All the cleanroom views! Love it! I manufacture gene therapies in grade A -grade C cleanrooms, but NASA's cleanrooms have always been a dream for me to see or even work in.
from 11:00 onward i was just waiting for that mug to play a role in your explanation
Let the Thing begin.
Thank you Dr. Becky, that was fascinating and I'm looking forward to hearing what the research uncovers. And, your nail polish matches your mug 😀
Love the bloopers!
Hi Dr Becky
Loved your explanation, never ever lose your enthusiasm.
Regards
John
Yarkovsky effect - yes please. Thank you Dr. Becky....you have me and the kids fascinated in space and science.
What equipment do you use? Mike and camera specifically. Your presentation is always first rate with content and production!
