👩🏽💻 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.

For those expecting a video on the gravitational wave detection from pulsar timing arrays, I’ve been reading the papers all day and have just filmed a video that will be edited ASAP and be on my channel next week. For now I’ve got a short video out with some info: czcams.com/users/shorts-3xudiCEkxM?feature=share

The only expectation I have a few dr. Becky is interesting content. I'm old and retired I just enjoy your content. Do what you can when you can and I'll be happy!
According to captions it's jellyfish tea.. Not JWST. xD
Everyday when I look at the Sun I say "Thank you for being the calmest star in the galaxy and not striping our atmosphere to nothing."
"No problem, pal. I might cause some civilization ending electromagnetic phenomena at some point though."

As someone who once worked as a spectroscopist, one of our greatest struggles is ascertaining how each stretch or peak corresponds to a particular molecule and nothing else. Many of these signals tend to overlap or translate downfield or upfield and it's actually unlikely that we can just "zero-in" on specific molecules that we want to observe. An atmosphere is basically a soup of molecules with each component possibly interfering with each other's signals. Sifting through this data is a daunting challenge especially since we cannot perform actual chemical analysis on the planet to confirm their identities.
Good points, meaning some of the results really are "educated guesses" and may be incorrect. I am an Analytical Chemist, spectroscopy is one of the things I have encountered and used occasionally in my career.
I've often wondered about that. I've taken a job in science support and apart from running biases, focussing the spectrograph is a nightly activity before observations begin.
In the near future AI will likely make sifting through the data a non-issue.
To quote George Carlin's Al Sleet (your hippy-dippy weatherman): "Don't forget, kids - behind every silver lining, there's a dark cloud!" It's been a good while for me, too, but (without looking it up), I seem to remember some of the gasses (CO2? H2O? Liquid H2O in clouds?) have some fairly lonely peaks. Again, it's been a while.
I'm not terribly optimistic about red dwarfs, to be honest. I would think that a volatile compound with a high melting point (water, CO2) would vaporize on the hot side and eventually wander over to the perpetually dark side and freeze there for good. Or would that movement of mass from bright to dark possibly create a net torque on the planet in its star's gravitational field that would give it a spin strong enough to overcome any tidal forces in the rocks and molten core? I also seem to recall that there's a DNA analg that has another letter in rungs of its ladder. That particular configuration is too stable (again, from dim memory of the past) to work on Earth, where the molecule needs to be ripped apart and sewn together easily in order for terrestrial life to function, but maybe in the higher radiation environment of a red dwarf, some of the activation energy could be supplied? Just a WAG - ochem wasn't my thing.
I guess at this point, I'd expect tidally locked planets with any potential ocean frozen forever on the dark side of the planet and nothing in the atmosphere but CO2 or noble gasses, maybe, on the hot, permanently lit side.
But interesting none the less. And here's your weather report!
@@joshuajackson472 Actually, spectroscopy even at a school lab setting are now mostly AI-assisted. The problem lies in the contextualization of the results. The possible combinations are simply staggering especially when organics get involved.
I love how you analyse, interpret and communicate the data that you see. Thank you for your realistic, non sensational take on the world of cosmology and astronomy. You are awesome ❤
P.S. CZcams captions for JWST are things like "Jellyfish Tea" 🤣
And for some reason, "Jenny Brewster". XD
@@Archgeek0 Huh? The midwife? A random influencer? The "Director of Market Operations" at Tia? Your response makes no sense, at least to me. Please explain.
@@Bill_the_Red_Lichtie The captions. They interpreted JWST as "Jellyfish Tea", and then "Jenny Brewster", which I in turn interpret as the name of a coffeemaker the CC algorithm had a crush on during development.
Also, sweet, DP icon! Cool to meet a fellow UFie in the wild.
@@Archgeek0 Now I get it, JWST was interpreted as "Jenny Brewster" 🤣
I have 2 signed copies of the UF comic books, I always loved Dust Puppy. Nice to see someone even knows what "User Friendly" is. You rock 🦾
I also think she does an excellent job of balancing background explanation with presentation of results. In other words, she knows much of her audience are enthusiastic about scientific inquiry, and can handle technical information, but usually need context to get the significance. Just like explaining here the two graphs, where the apparently shallower one was actually much deeper because of different scales. Dr. Becky does not talk down to those of us without astrophysics degrees, but brings us along.
Agreed. Red dwarves are notoriously unstable. Our sun, it turns out, is relatively quiescent. It rotates slowly, and the planet are much farther apart from each other than most of the solar systems we know of. And still earth is the only planet that has complex life forms on it.
I expect that life exists on other planets but they could be far more scarce than we imagine.
Doesn't our detection methods (star wobble and transit) skew the results because IIT is hard to detect smaller planets further out.
@@AORD72-- Yes, our exoplanet surveys are all but certainly skewed to large planets and close-orbiting planets. The vast majority of early exoplanets were hot jupiters, and we don't know if that's because they're common or not.
I had a mental image of unstable red dwarves with long beards swinging their axes around.
A lot of astrobiologists are pretty confident that F, G, and K-type stars can support habitable planets. That's about 22% of all stars, which isn't super rare. M-type (red dwarf) and A-type (blue-white) stars might be able to support planets with simple single-celled life as well.
In matter of fact, we don't know if Earth is the only planets with complex life, we suppose there isn't life in the other planets, but as far as we know, we just spot a shadow in front of a star and make a lot of assumptions. One of the assumptions is that life has to emerge in an Earth like planet. But, why?. What is life?. A more stable scenario for life to emerge is a moon from a distant but large planet, really far from a star, energy would be taken by the heat of the gravitational forces between the planet and the moon. But how are we supposed to see those planets, we just see the shadows of nearby planets around the stars.
Just because of the flaring issue, I never much liked M-class stars and never held out too much hope. Even if the very vast majority are incompatible, that still leaves a fair number just due to the fact that they're incredibly common. And there are always the more-comfortable and still very common K-class stars out there that tend to be a bit less temperamental. And our own G-class, of course, even if not so common.
Yeah, orbiting a G-class star would be better.
I hate M-class stars too! Let's get 'em!
@@scorpion-man28K.
Yeah, l am not sure why it is that the scientific community and people in general seem so hyped about searching for life around red dwarfs. Given their common volatility and how closely planets have to orbit them to be habitable, it seems almost a no brainer that they are unlikely to harbor life. I'm not saying it isn't worthwhile to study them and their planetary systems, but why anyone is hyped to find life around them is beyond me.
im waiting for the same research to be done on tau ceti, its our nearest g class at only ~12 ly away. surely must be near of top of the list of the list
I've waited ~70 years for some real empirical estimates of habitability of a promising candidate interstellar planet. As long as I don't kick the bucket, waiting another year or two is fine . . .
A planet fit for humans?
Exceedingly unlikely for two reasons:
1. A 50% ice planet from the outer solar system, somehow came into our orbit and then crashed into us very very slowly...so that we didnt become another asteroid belt. Bringing water to a place where there's not supposed to be water.
Also bringing an extra injection of iron to our core...which is why we have a magnetoshere protecting us.
Brining us a moon that keeps our tilt stable.
2. Life itself has terraformed Earth way more than most can imagine. E.g. Oxygen doesn't typically occur in armospheres (and if it does, it typically means that planet has been stripped of water).
So an Earthlike planets can't exist without life to make it that way.
It's exceedingly unlikely that there are spare planets out there. We need to take care of this one because it's likely the only one that habitable for earth-life.
What if they’ve already discovered it they just haven’t informed us about it.
The more we learn about these other solar systems, the more amazing and unique our own becomes.
kind of. but also not really. we have not examined anywhere near enough exoplanets to make that assumption. it is quite likely we are not as significant or unique as we think or might hope we are.
@@joederbyshire_ Haha Rare Earth 100% the Theia impact is the only reason we have an atmosphere.
@@Neloishnot really, it’s the reason our atmosphere is not as thick. Also most gasses came from within the earth through volcanoes
@@joederbyshire_ Hoping has nothing to do with it. I seems very obvious that it was a very specific set of circumstances that life exists on the Earth. We are still finding out what those are. Venus is pretty much a twin planet by size and mass suggesting it contains many of the same elements as the Earth. It has the same sun but is 70% of the distance from the sun than the Earth is but it is much hotter. Both Venus and Mars are in what some scientists have labeled the "Habitable Zone" but neither is habitable for life as we know it. It seems that the Suns habitable zone is much smaller than postulated.
@@Neloish i would argue that if that is your only reasoning for us being a rare planet then it is a bad one. it is likely events like the Theia impact are commonplace, and it would just be a case of having that event happen in the habitable zone of a star. if we are to use your reasoning that is (which we shouldnt).
What a time to be alive! Thanks for this, Dr Becky.
So good to be briefly well informed on astronomy because your videos! Thanks!
The absolutely best astrophysicist on the internet, and possibly in her chosen field of study. Thank you Dr. Becky for what you bring to us. I do pray you are granted some research time on JWST, that would be awesome to see!
but can she play table tennis?!?

Patrick Moore would be proud of you keeping us well informed of astronomical news 😊
Rather watch Dr Becky than Brian Cox anyday, just a personal opinion.

Ooooh, shots fired! 🤣🤣🤣🤣
I'm torn there.
Dr Becky is more entertaining and lighter, less intense of a personality (and let's be honest, far more pleasant looking) but Brian does take us out on cool adventures and have a very cool approach.
Plus I do like that Brian has the balls to call out the invisible skydaddy superstition peddling as pure nonsense. I love it when a fellow Atheist speaks out.
😁😁😁
Get back to me when they finally look at Trappist-1E. That’s the jewel of this system.
Jellyfish tea and Jenny Brewster for JWST... whether it's because of the accent or not, the closed caption auto-interpretation's quite funny!
I've started reading it as joust 😆
I find all these planetary systems fascinating even if they don't have life. Each one seems unique and full of wonder. I got Jenny Brewster and jellyfish tea for JWST.
According to Google closed captioning, Dr. Becky saying "JWST" equates to "jellyfish tea" at 19:04, and "Jenny Brewster" at 19:21! LOL
“Tell me how I’m supposed to breath with no air” is an award winner
Breathe*
My main worry is that even if TRAPPIST-1 or other Red Dwarves are stable enough nowadays, how much volatile material is stripped during its earlier, more violent years? It could potentially render the system sterile by removing the majority of the water before things settle down. Hopefully that's not the case farther out. I suppose we'll see. c:
Wouldn't catastrophic atmosphere loss be exactly what you expect to see close-in to a an active flare star?
Clever adjective!
Yes, but it's good that it was verified. Not likely to have any life.
yup. That's my take. I expect all of these planets will have stripped atmospheres, and without an atmosphere, surface temperature, and surface rock composition will impact on reflectivity. i think we can expect ultramafic surfaces for all of the planets in the Trappist system, other than perhaps the outermost, which might be glacial if we're lucky.
@@nickandrew4650 It's good that they're doing the investigations; I just don't understand the consternation from scientists over what seems to me to be an expected result.
@@ariochiv They're hoping for the better.
I still find this all fascinating! The more we find out, the more we learn.
Well isn't that true of everything, all knowledge?
1c sits well outside the habitable zone so the initial data shouldn't be too surprising. Hopefully follow up observations will be able to give us a more complete picture. Now on to planets d, e & f!👍👍
Yes d, e & f... which is what they should have focused on in the first place instead of wasting time with the incredibly hot zone planets.
And G... let's not skip G 😊
Trappist-1 D, E, & F were reportedly the very first targets of JWST, but this was apparently kept secret, you can find articles about JWST's first targets being "Super Secret". The reason they're kept secret is because they detected an advanced civilization.
Love your passion when your talking about things we may never really know for sure. Gives the subject of your videos a sense of wonder. Thank You
Great stuff Doc. Please keep them coming 😊
Exciting. Can't wait to see the results of the other 5 planets. Will you make videos with updates of the trappist-1 system in the future? It would save me a lot of research time. =)
The orbits of these planets are all so close together...
The view on those planets has to be amazing!
Imagine, how mars or venus would look like from earth, if they were just like 4 times further away than our moon :o
Venus would be about the size of the moon in the sky.
Mars would be half that.
Saturn would be 10 times bigger than the moon in the sky. Imagine that sight.
It'd be similar to how the moons of Jupiter look from each other.
Fascinating video as always. I turned on auto captions when you mentioned them at the end and mine came up with "jellyfish tea" 😂
Can't wait for more Jellyfish Tea!
Captions also said "Jenny Brewster" later in the video.
Another fun video, thanks, Dr. Becky. Cheers from the Paific West Coast of Canada.
We failed math fabulously all through our academic life - yet we *are enamored with the wonders of physics, astrophysics, and sciences across the board* - we are sufferers of the inability to grasp maths across the board. Thank you so much for continuing to make this daunting topic somehow so addictive.
It is after all, an analog to our systems Venus so I’m not thoroughly surprised. If they’re all the same I’ll be disappointed though!
This is excellent data and I appreciate your input on this subject. I look forward to seeing more information from Trappist 1-d and Trappist 1-e! I appreciate you!
Thank you for the lack of dumbing down or sensationalising.
Awesome teacher Dr B
Basically, with the close and fast orbits for habitable zones around red dwarfs, looking for habitable planets there is like looking for lost keys beneath a streetlight: it's where we can actually see them.
I was thinking of that joke too!
D,E and F will be the go 🤞🤞
always great info from you
THANKS
As always, great video, thank you!
Having Trappist-1c being stripped of its atmosphere by the red dwarf star is what I expected, admittedly based entirely on gut feeling. But still. I think the data from the other planets will support the Red Dwarfs are bad host stars.
New-ish subscriber, and love this channel. Thanks for explaining allllllll of this so clearly. 💖
Welcome! 👋
Just love watching your videos. Presenting measurements and facts. Your enthusiasm is infectious! Thanks! I imagine you'd be an inspiration to your students.
Thanks, dr. Becky! 😊
Stay safe there with your family! 🖖😊
I'm looking forward to seeing spectrums of each of those planets.
„Not what we have hoped“ I hoped you would do a video about the new Gravitational Waves discovery 😂
Thank you for update and all the great info as usual!
Also, during the bloopers I went back and looked at the CZcams auto captions for when you said JWST quickly and it got “jellyfish tea” 😂😂😂
Wow i finally found a person who doesnt try to hype up the context or dont give useless information! Happy to find this channel
It will take time, but I hope we can look at enough planetary systems around other stars to get a real estimate of the probability of life.
We never will. There are just too many stars in The Milky Way to ever be able to look at any Majority of Stars in the galaxy.
@@matthewjohns1758I wouldn’t say never, give us a few million years.
That statement doesn't make any sense.
To calculate probability, you don't need a full sample.
E.g. Let's say a have. Truckload of sand. White and black grains mixed.
All I need is a small sample of sand to calculate what percentage is white and what percentage is black.
It's kinda like saying it's impossible to measure a person's blood sugar level without draining every drop of their blood. Then saying there are just too many protein molecules in the blood to look at every single one.
Thanks for this content Becky which answered pretty much every question I had on this subject. I don't think we should necessarily be disappointed by these results from Trappist 1b and 1c. It's some of the best data we've ever collected on exoplanets so far and will help us make our searches for habitability in a more targeted way in the future.
I don't think anyone was surprised that 1b is a supermercury. I don't blame our host one bit for ignoring that announcement, it's like the discovery that northern England is often cold and damp.
1c on the other hand is about the same size of Venus and gets a little more sunlight, so finding out that it has less atmosphere than Mars(!) is newsworthy.
I like this attitude. All data is good data!
Thanks for your take, Well done.
Very cool, thanks for this. I'm also halfway through your book on black holes.
Excellent explanations of the process for interested young folks and those of us preparing to go white dwarf and have the hair color to prove it .👴😀 Thank you. Dr. B.
I love the great range of material and diverse target audiences of Dr Becky's videos. They target everybody from the lay person, who can probably pick out the Plough / Big Dipper, to the people who have a decent grasp of astrophysics and know the sequence of nuclear reactions that take place in stars heading towards a supernova.
👍👍
Thank you Becky for the update. Yeah, I think planet d will be the most anticipated. We just have to wait.
great video as always. you are so good at explaining things, and i really admire your dedication to learning your profession.
I'm generally a huge pessimist with red dwarf stars. The variability I think is just too much for planetary atmospheres, and the Trappist data only reinforces my view. :(
It's not all about what you think
@@dtutsselthis comment is though
@@dtutsselit's about what's real.
If astronomers stopped studying Red dwarfs they'd be spending most of their time twiddling their thumbs simply because there aren't too many candidates of the other star type systems with planets, to study.
Life on red dwarf planets is exceedingly unlikely...but learning anything new about any star system is still interesting af regardless. So if not, why not.
Plus, we already learned a lot about our own solar system mostly from red dwarfs. (so it's useful).
E.g. apparently it's not normal for our main Gas giant to not be suicidally spiraling toward the sun while vacuuming up everything.
@@tylerdurden3722 It's not so much that scientists lack other things to study. It's that it would be really bad science to ignore such a huge realm to study even if it is an unlikely one. Best to rule it out if you can.
I think there is still hope. In the graph it shows 1c isnt that likely to have life because its not in the habitable zone. we still have d, e, and maybe f.
I absolutely love your videos! You are a brilliant and wonderful presenter!
You made me smile when you sang red red dwarf to the tune of red red wine 😂❤
Thank you so much!
The Sound of your voice is very comforting, thanks for sharing.
Great work breaking this info down for us mere mortals. Thanks Becky!
Trappist-1c is outside the "habitable zone", too close to the star, so it's no surprise that the results for it aren't as we would like to see.
I'm much more looking forward to the results for d, e and f - they should be a lot more interesting.
Definitely and planet G too. No thick CO2 ok but still O2 ,N2 atmosphere possible. the most important is to measure temperature of the planet to be 107 C. I am really curious about D, E, F, G,
“Dayside” was mentioned in the paper. Does that mean that they know with 100% certainty that it’s tidally locked now?
You could use Dayside as in "Dayside at the time of observation". But with the age and proximity, it's all but guaranteed to be tidally locked. Although I don't think we will get any direct evidence of that, as there is no real mechanism to test that. Aside from direct imaging, which is not in the cards until some mind-bending-sized space telescopes.
Thank you, this is very helpful for my dissertation. I'm excited to see more JWST exoplanet data.
Love way you explain it all sweetie good job!!
Well, this pattern suggests that Trappist-1e should have a nice 25ºC, my favorite temperature for life (I actually find Earth a bit too cold, especially in winter). When will we be able to move?
I'm so excited about that possibility also. We will have to learn to grow our own plants.
Start building your rocket now! At a distance of 40 l.y., it will take "a while" to get there (just like it took Deep Thought "a while" to ponder the Ultimate Question in HHGTG.)
The goldilocks zone around a red dwarf is very close to the star.
Which is why goldilocks planets around red drawfs are typically tidally locked with the star.
These planets have two extremes. One side is extremely hot, while the other side is extremely cold. If you average to two extremes, you end up with an average that is mild....e.g. 25°C.
@@tylerdurden3722it's also very thin due to the small size of the star itself. I'm honestly having doubts about Trappist 1
I'm sure there are alien birds that migrate from Trappist-1f to Trappist-1e for the winter.
isnt the goldilock zone around a red dwars so small that the planet would be tidally locked? which would mean a very small habitable zone at the day/night border
It can't be terribly habitable if it has little or no atmosphere, though...
@@PeloquinDavid that is absolut true
IF a tidally locked planet were to have an atmosphere, wouldn't the habitable thin strip at the perpetual twilight be a perpetual, never ending mega storm due to the extreme hot side air clashing with the extreme cold side air? If this were the case, that thin "habitable" zone on the planets surface wouldn't actually be very habitable.
"jellyfish tea"! Love it! Never would have turned on the autocaption if you hadn't asked. :-D
….and the last time you said it, it thought you said "Jenny Brewster" (also replaced "bloody fast" with "pretty fast" but not sure if that's inaccuracy or censorship.
Thank you Dr. ❤
hell yeah space rules
Not to be a solan chauvinist (Sol-vinist?), but wasn't this expected? Blasted barren because they're so close?
A lovely dream to have, but quite unlikely to find anything compared to life-hostpitable.
Congratulations, Tobias!
I have been waiting for this. I have looked at some of the journals that are available but I’m only a chemist and not an astrophysicist. I love your content so much. Sad about the Trappist system. I’m so excited for Europa especially that Ph has been detected. ❤
Hopefully we can go to other solar systems in the future
Not at all likely, though. It's hard enough going to the Moon.
Is there an efficient way to measure the magnetic field of exoplanets? That can also affect a planet's ability to hold on to an atmosphere.
It’s the main reason a planet holds an atmosphere, especially that close to a fusion reactor with no containment system
If it has a decent atmosphere and especially hydrogen that hasn't been stripped away by the star, that would probably be a very good sign of a magnetosphere.
It's also possible to determine the density of a planet.
The earth is the densist planet in our solar system. Mostly due to out unusually large iron core.
If we find a very dense planet like our own, it might be a sign that it too has a relatively large iron core.
I am not a Dr...but I love learning things...and have always been fascinated by space...thanks for these videos, I find myself saying yep, and oh wow...keep um coming Dr Beck, really appreciate these videos!!!
Wonderfully interesting and understandable report/explanation.
Looking for habitable planets around a red dwarf really seems like sorta a waste of time. They very typically tidally lock their systems planets and have wild fluctuations in UV output.
Did you listen to the whole video with the case of why it's being done?
Unless we know at what stage the Red dwarf is it's kind of putting the cart before the horse. The first thing we need to know is if the Red dwarf is that the beginning of its cycle or the end. These planets could have been sterilized by trappist-1 at the beginning of its red dwarf cycle. We're checking these planets after that oh, it will be a fruitless search. Granted I'm not an astrophysicist. If I'm wrong please let me know for future reference.
@@ug333 of course I did.
@@JohnRodriguesPhotographer Red dwarfs are the longest lived stars. Every single one of the small ones is in the early stages of its life just due to the age of the universe. But that early stage might last longer than our sun.
@@michaelfried3123 she kinda explains why it isn't a "waste of time".
So far the results are amazing but the planets are a bit rubbish 😂
Thank You so much Young Lady I know we all had great hope and it is still early. In the first days of SETI I had a PC at home and I signed up to let them crunch numbers at night while I was not using it. I did that for years until it became a problem with security. But with this research i had not followed it close enough to fully understand it all your lectures shed light Infra red even on the topic and the charts were great too. Thank You for all your work. so glad you are able to share. Take care and keep chugging. Dennis in Virginia
Very video Dr. Becky
Great idea. Let's hope we find life that loves to be roasted alive and does not have to breath. Let's look around Red Dwarf super flare stars. Didn't proxima centauri just have a solar flair that was 100 times anything we have ever seen from out own star? Hey, but it is easier to see planets around dim stars. So there is that.
I was under the impression that the Trappist system was more-or-less ruled out for having habitable planets because of how close-in all the planets were; There's a very high probability of the planets out to the edge of the habitable zone being tidally locked, which negates any other factors in their chance of harboring life
All that is to say that I'm surprised they're spending any time looking at the system.
(Also; temp+atmosphere models aren't always as you/she described, there are some very close-in hot jupiters (there's one I can't remember the name of, but it's like pitch black, blacker than coal) that's like 8,000 degrees despite having a very thick atmosphere.. I think it was called a puff-ball planet or something like that)
Thank you for sharing all this information and insight
So much waiting… 😔
Thank you for enlightening us. 👏🏻
Interested in the gravitational vid.. 👍🏻🙂
CZcams's auto-captions are reading JWST as Jellyfish Tea during the bloopers!
♦I was expecting those results from the beginning. I am of different camp and look at biogenesis facts for what they are and not what I want them to be. You will never find any planets with life on them. Biogenesis chemistry is so incredibly complex. Even in the best labs it can't be reproduced. Time and randomization is not on Biogenesis side in the universe.
As always a brilliant presentation.
Thanks Doc learnt a lot more then I thought I would.
If they are inhabitable, we can still send Russians there …

Glad the lay conversation is moving towards more nuance in discussing terrestrial vs earth-sized vs earth-like planets.

You nailedit Dr Becky! Rofl

Great Becky
I was definitely hoping for a spectrum, but the currently released information is well within expectations. Looking forward to further data.
Jellyfish tea
Which I think is quite fun!
Another interesting Jellyfish Tea video - thanks 😊
Well, we'll all just wait. But thank you for keeping us updated regardless. It is fun.

If they had an idea that those planets may mirror ours. Then why didn’t they start with a planet based on distance that would most likely be the earth analog
Always love your blooper reel at the end, and to see what little ditty you make up to sing, but as you were talking about Red Dwarf's, I think you missed a trick not singing the theme tune from the BBC tv show Red Dwarf! Loved the video though, and thanks for your hard work in educating us about the wonders of the universe.
Thanks
