👩🏽💻 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.

If you noticed anything different for this video it’s because I worked with a video editor! Jonny Hyman did a fantastic job at keeping the style of my videos while also adding his own creativity. Show him some love: www.UA-cam.com/@thehumanverse
Good work Jonny!
Why is the return splash down of Artemis important?
In other words, this has been a Dr. Becky Studios Production. Congratulations on your progress.
Maybe it's the seamlessness between the illustrations and graphics with voiceover and your office? Any case, I gather the new editor must have called the Artemis astronaut a dummy...
Super editing and presentation. Fabulous overall. Sound good too.
I'm thankful for Dr. Becky!!!
she's a gem ❤️
She's very attractive too 😍
@@fieldadmiralspartanryseb-8293 bonk
She's a minefield of great information!
@@stephenbedford1395 I wouldn't call it a minefield... ...I'd refer to it as a plethora or bounty of knowledge.
Hey Dr. Becky! I actually am a NASA scientist, and I wanted to let you know that we absolutely will not have the next touchdown on Christmas. Bless you for your enthusiasm and informative sky reporting!
From when my niece was a baby, I used to spend time showing her objects in the night sky and watching Dr Becky's videos with her. It's something that stuck with her and now at 8 years old she has the most incredible knowledge of all things space and watches Dr. Becky's videos herself. Thank you for fuelling such a healthy passion in her💞
That’s so wonderful to hear Justin, thank you for sharing! And say hi to your niece from me 👋
@@DrBecky thank you. I will say hi!
That shows you are a good grandfather. Congratulations!
Justin, such a heartwarming story. Cheers from Michigan.
@@h.i.5280 Since it's his niece, he would be an uncle, not grandfather
One of my kids burst out laughing one night and said, "Moon 'tending be fingernail!" My late wife and I referred to the crescent Moon as "TBF Moon" forever after.
You're right about the Artemis shot being the "Blue Marble" for a new generation. The thing that struck me when I saw it was that it's the first time I've seen a picture of the Earth like that partially in shadow, I always think of the Earth in its "full" state. Was very cool.
The mission is cool. But Artemis itself is an over-priced obsolete piece of junk.
And it's a round ball, go figure!
Actually the picture "Earthrise" shows the earth partially in shadows and is older than "Blue Marble" (made from Apollo 8 in 1968, so before they even landed)
@@sebastiannolte1201 I watched a video not long after this one that showed "Earthrise" and realised exactly that. My brain must have changed it in my memory.
@@ThatBoomerDude56 "Artemis" is the name of the program. The spacecraft is called "Orion". and the rocket is called the Space Launch System.
But Curious. How do you think is it "obsolete"? The demands of deep-space re-entry will pretty much require that any deep space manned spacecraft look like Orion (or Apollo before it) . iIe. a blunt cone.
And no nothing Musk is working on will be capable of deep space re-entry.
Off topic but as no-one else has mentioned it, congratulations on your recent appearance on The Sky at Night! Another career beckons….
I love doctor Becky endless excitement I may not share her brilliant mind but her excitement in all new data that I can share ☺️ stay safe and keep looking up
Her excitement makes me excited. Lol. 💞
Just to say thanks for making these wonders accessible and understandable (sometimes) for us lay people. If my intelligence was on par with my sense of intrigue and wonderment I would be working alongside Dr Becky and her colleagues but alas that is not to be so to have someone from that world taking the time to open the door is such a gift that is so appreciated.
Thanks Martyn 🤗
Thanks! Love your shows. Keep up the good work.
LOL, the Mercury marker zipping past like the ancient god it was named after, there at the beginning, made me giggle! And Jupiter being the brightest thing in the sky once in awhile was something that I won a bet with my nephew over - he didn't know that any of the gas giants ever got that bright in the sky, and was _certain_ it was Venus or even Mars! 🤣 He forgot that Aunt Mary was a huge astronomy fan. 😏
Thanks, Dr. Becky, for all you do!
Dr. B, I would really love to see a video where you go into depth about another round of JWST photos, explaining what we're seeing and what information we're learning from them! 💛
Well next week’s video is that but for spectra not images - is that ok? 😅
Dr. Becky! You are the sweetest and most beautiful English person who bothers to tell us dummies about everything. Thank you for your very thoughtful way of saying things, and your hopeful smile, and for being who you are. I also hope that you will speak as hopeful when we reach the moon. Think that we in 2023-2024. you can also see man on the moon! wow!
I love your enthusiam, Dr Becky! I'm a big fan of space exploration and astronomy, and watching you talk about the current missions and events is a hoot 😀
You do a great job describing science stories in a way that inspires excitement. 👏
I love your bloopers! Dr Becky obviously has lots of fun with them, though they're obviously truly spontaneous.
Your enthusiasm for the subject is infectious. Loving the videos
Dr Becky, you mean you're a professional astronomer and you actually go out to look at the stars in the sky?
BRAVO
I absolutely love all your videos!! Your enthusiasm rekindles the enthusiasm I had some 65 years ago when I saw Saturn for the first time through my telescope!! Keep it going!!!
Finally received your new book - A Brief History of Black Holes - and am enjoying it immensely!!
Glad to hear it!
Thanks Becky and have a Merry splashdown-free Christmas. We don't want little kids worrying that a sleigh/capsule collision might occur!
Exactly!
I always so enjoy watching your videos. You are clear and concise for us amateurs to space science. Look forward to see you every month.
I can't remember if it were the Eta Aquarids or the Geminids, but around 2007 / 08 my friends and I saw a BURST of meteors. A real meteor shower. Like those mediaeval pictures portray a shower of hundreds of tiny faint streaks per second, this lasted about 5 minutes (with a ramp-up to the peak and down again a day or two each side). We were expecting a peak of activity but not the burst like we saw. I've not seen anything like it since.
It's hard to believe your eyes without friends there seeing the same thing.
07 or 08 not 9?
@@secondchanlefullname correct. 07 or 08, but not 09. (I was overseas in 09) 👍😎🇦🇺
I'm so unqualified on this topic, but as curious as any earthling should be. I Watch DrB's videos and am able to understand some incredible complexities of the subject, without getting lost in jargon or confused by the boring oversimplification that's rife online with most content creators. This is just top level facts, with great images, enthusiasm & clarity. Superbly produced episode.
Congrats on the Sky at Night cameo! Richly deserved.
Thanks for always keep us informed and doing it with all your enthusiasm, knowledge and charm!
Brilliant episode. Exciting news. Thanks for the heads up of the calender.
Wonderful presentation. Thank you Dr. Becky. Your enthusiam for your subject is infectious and really helps keeping me engaged, and to keep looking up!
That video of earth from the Artemis 1 is now my screen saver, it put life in perspective. Everything we do during our whole life will be carried out on a Blue Rock surrounded by harmful darkness. That's why i got involve with astronomy because we all need to take the time out to appreciate the life that Earth is providing for us all.
It is just an incredible reminder of why we’re all in this
Excellent video as always. Thank you for sharing your passion for space.
I always love these news videos! I was hoping you would mention the kind of unexpected meteor (bolite) over Norway - I would definitely love to hear news of that when we have more info!
Thank you so much for these videos.
The combo of your excitement and the launch of JWST has really inspired me, I've started my degree in Astronomy this year after 10 years out of education.
Very good summary Dr. Becky!
And @SciManDan, lots of things / observations to slap the Flerfs with!
Watching your excitement last Christmas morning was one of the highlights of my whole Holiday Season! 😀
Dr. Becky. Good evening. The live stream from Artemis looked like a cartoon movie . But there is a reason why. I will explain: the transmission rate of Artemis is 50Mbit per sec or ~6.33Mbyte per sec. Therefore in live video stream of 50 photos per second , every photos is no more than 120Kbyte. Hence, the resolution in live stream was medium. Cannot be HD in live stream. If Artemis transmission power is 100Watt per second, and the distance from earth 380000km. And the parabolic antenna radius is 35M. Abd the antenna gain of artemis is low close to one (it is not voyager which was 64000 the concentration of Energy in space). The Earth's deep space parabolic antenna received only 2*10^(-13) watt. You cannot have hight rate of information in 2*10^(-13). Therefore to see streaming in 4K it is impossible. You need parabolic antenna in Artemis with high gain . However there is a DSLM camera with width lenn. For high quality photos . These photos have very high resolution and the are published latter after hours.
Always looking forward to these videos! GREAT 👍
Thank you, Dr. Becky. Love the general news and the Whinchombe asteroid-water news is really exciting. thanks again.
Like JMG's ending comments on each stream, I also look forward to seeing your blooper reels! One of these days I'd like to see a video compilation of the best, or worst (depending on the POV), bloopers. Maybe make it an annual thingy: the best bloopers of the year video!
Once again, super interesting! Thanks, Becky!
Just 💕 you videos and content. Your enthusiasm is very refreshing 🙂 ty
Thank you for the chapters !
As usual Dr becky a interesting informative video. I wondered about just and meteorites the other day
Informative, and entertaining.
Thank You!
Thanks for communicating your passion and informing us. You are amazing!
Your sky news always enthralling!
It's Christmas time and I've decided to sub, like, and such to channels I frequently watch. I dig what you do and I hope the few pence of ad revenue I'm providing helps you and the family out. I still use an ad-blocker, but I digress... Merry Christmas!
love those videos!keep em coming! :)
Sometimes you make Meknow I know very little,but you also expand my mind.Thanks Dr. B
Awesome! A hardcopy of your book arrives to my door today 🙂Happy Holidays!
Love your stuff Becky! Keep it up :)
You did it again. You really are the best!!! Happy Thanksgiving. May all you desire be yours always. LLAP 🖖
i was waiting for this vlog since months
Great night sky and space news updates - thanks!
Dr. Becky I am so impressed with your videos and love learning from you! I could watch your outtakes for hours... It's so funny watching you riff, sing and just futz around! I'm a sucker for entertainer's outtakes as well. 😉😁😂
Scotty!! More power to the deflector screens!!!!
I keep wanting to hit the thumbs up button... but keep forgetting that I hit it earlier in the video. 🤣 What an AWESOME video!
Pretty and informative… love it! Thx
Your hands are mesmerizing. I adore your thoughts and updates on the cosmos. 💫
Love the content. You are freaking awesome!
Thanks, have a great weekend!
I am so happy about the Artemis missions - I was quite young when the last Apollo mission landed. I stayed up until Orion separated from the ICPS so I was pretty tired at work the next day - I'm in the Pacific time zone or GMT -8h. I only recently learned about the amount of radiation the Apollo astronauts received in the Van Allen Belts and was quite concerned about sending more people through that region. I was very happy that they are testing potential shielding suits for astronauts to wear when we return to the moon. I also always love to hear more about JWST.
Dr B smashing out the park as always ❤
One of the best blooper segments ever!😂
What a great show. FYI, I'm old enough to remember Patrick Moore and his 'Sky at Night' (in fact used to frequent the same pub lol), so it's good to find someone with equal enthusiasm and a desire to convert all things astronomical into plain English (Thank you). At the risk of getting a slap, though, you also talk at the same speed lol.
At 6-45 , nice view of Cuba, the Bahamas and Florida.
Love your videos Dr Becky!
6 min in, perfect timing :))))
Absolutely love your videos Becky. Great content and really super presentation. You're clearly a natural. The next media scientist in the Uk maybe? The *new* Brian Cox type :)
Keep doing nighttime news!
MAZ and MOID... Lots of fun words this time. Really cool about that meteorite research.
Thanks, Dr. Becky!!
thanks for posting this
love your vids
Hey got a like from Dr Becky wooooohoooo!!!!!
I love your Shirt, awesome show , those new JWST pics look amazing 🧃🌊
Wow, that carboniferous chondrite story was super-cool! Thank you for all the awesomeness Dr. Becky!
Last Christmas was my favourite Christmas BECAUSE of the launch of the JWST.
I am thankful that you are here to break all this down for us! You are my very favorite astrophysicist! Sorry, NDGT!
Sorry not sorry 🥳
And thanks for making it fun.
Yay! A new Becky talks Space video..
18:00 and of course, 0.05AU is still 4 and a half million miles...
Heyyyy! You made it on to The Sky at Night! Well done - true fame beckons! Next it will be a spot on the One Show and a cameo on Eastenders. 😁😁😁
Love the PP reference, it is a gem of a movie.
Brilliant! Becky you have such a genuine joyous upbeat enthusiasm about space it’s just great!! -it really is a pure delight listening to you, and learning all the cool astrological data is also good too!! I’m curious is Jupiter even brighter than Sirius then as I’ve been wondering awhile as different astronomers give different answers so am still not sure what the extremely bright star/planet is I find myself gazing in awe at each winter!
This completed my day... i mean, my night.
Thank you Becky and thank you jonny 👍🙏
Just thinking of Dr. Becky and a video appears. Fun video thanks!
Thanks for sharing!
I just looked up last night and noticed Mars is super bright! Can't wait for and occultation.
Dr Becky you need to watch His Dark Materials. All that talking about dust just has me wanting season 3 release here soon.
Putting in proposals for observation time = Olympics for space nerds. Loving it.
Great graphics and rich content. Really good.
Twitter is still.. alive, and I love the bloopers, great videos has them, keep it up
Thank you Dr. B.
19:01 🎶"I saw the news today, oh boy. A rock came down in Winchcombe Gloucestershire. And though the rock was rather small, they gathered up it all. Now they know the isotopes are similar to Terran crust..."🎶
Re: Winchcombe Meteorite - Dr. Smethurst, it would be very nice if you could explain in some of your future videos what is theorized to be the reason for different isotopic composition of hydrogen in comets vs. C chondrites.
Thanks for the great video, as always!
happy thanksgiving 🦃 to you, dr. becky, and here's hoping 🙏 NASA grants your Christmas 🎄 wish! 😊
I ordered your book when it first came out from Amazon. It was supposed to be here by the middle of November. Apparently there was such a delay and now I'll get it probably the first week of December. I got one for my son too because he really likes physics.
I received your book the other day in the post. I wish I could have had it personally autographed. ;)
Would you be able to make a video explaining more about micrometeorites? Sizes, how frequent they are, speeds and the damage they can do etc?
I was 10 years old when man first landed on the moon. Hope I will still be around the place when they next land there. Can't wait.
I am thankful that Amazon delivered my copy of "A Brief History of Black Holes" yesterday instead of waiting until January! Time to start chapter 2...
A wee bit O' nostalgia. Many decades back from primary school into University, being told, outer space is completely empty, thus devoid of anything. Hoot! even as a kid, just say'n. I'd ask, where did these meteor shower come from, random shooting stars, etc... then being told you are too big for your breeches.
This just another great learning moment, yes they should have realized this at this modern time, now they'll plan better in the future and advance tech for high speed and defensive systems.
Onward & Higher! Thank you.
