Impossible Moons

- Why haven't we found dozens of exomoons yet? With planets as small as the Moon having been detected by NASA's Kepler Mission, it's fair to wonder why we only know of a single exomoon candidate to date. Despite the lack of moon detections, there are actually hundreds of known planets that wobble around, a tell-tale sign that a moon could be present. Unfortunately, these wobbles can also be caused by other planets and so in a new research appear Prof Kipping and Alex Teachey have re-visited the theory behind exomoons and come up with a new trick to help us discern between the two - impossible moons.
Presented & Written by Prof David Kipping.

THANKS FOR WATCHING!!
#Exomoons #ImpossibleMoons #CoolWorlds - Věda a technologie
i think this dude emerging as one of the next greatest scientific communicators
this channel deserves way more attention, its one of the best of its kind on YT right now
While l may not always be on the same page, re our Prof's conclusions, l am on the same page re those who espouse his unprecedented style and presentation.
@@MG-er6dm well and as even the most cursory acquaintance with the history of science will tell you, particular results and conclusions can be fleeting, by their very nature, its the soundness of the PROCESS that is what really counts, and what distinguishes science from other epistemic endeavors like religious and mystical explanations, pseudo-science, and so on.
@@enaidealukal4105 Thanks for your comments. You made some really good points. Much appreciated.
I hope so.
Day 17 of lockdown NZ, I wake up feeling motivated: "I'm going to start that housework today"
CZcams: "New release from Cool Worlds"
Me: "I'm gonna take a raincheck on that housework, something essential just came up"
2pintsofcremedementh I’m also on lockdown in NZ and had exactly the same reaction today 😂👌🏼
Isn’t it day 19...?
I'm currently wishing I had upgraded my telescope when I had the chance last year. Had I only known the amount of time I was going to have to explore.
My workday is a bit delayed actually :)
@Norm Macdonald Showm0u
Prof.kipping...u should do every audio book...EVER
Agreed
I was just telling someone today that if Professor Kipping was the voice of every Science related, Spy genre, Alien genre, or pretty much any Audiobook, that I would be able to actually stay focused and finish them. There is something super soothing and relaxing about his voice. I find that when I’m extremely stressed out, I go straight to this channel to zone out and get lost in all the information and calming myself so much so that hours will go by and then I realize that I just watched 5 or more of his 30min+ videos. Once in a while, my days off consist of waking up before sunrise, start watching his videos and while doing so, subconsciously watching the sun come up, then drop below the horizon in what feels like no time at all that I look at the clock and try to figure out if that 6:00 time on the clock is PM or AM. 😂 (obviously this is exaggerated but HAS happened once or twice) This will sound odd and creepy but I wish he was my dad or a family member that I could talk to when I was going through tough times as a teenager. I would have been instantly calmed and able to think logically and practically. Lmao.
Concur.
This cannot be upvoted enough!
YES... YES PLEASE!
This channel is going to blow up soon, keep up the amazing content!
Yes!
I just wanted to thank you for yet another incredibly interesting, and obviously heartfelt video. Unfortunately,I was unable to recieve a College education, and I've worked as a tradesman to help support my family since I was 16 years old. My greatest curiosity has always revolved around the need to understand as much as possible about physics and astronomy, and the many great unanswered questions about the Universe we currently find ourselves in. At night before sleeping, I'm finally free to search for, and attempt to understand at least a little bit, about the newest theories and scientific finds. It's obvious that you have a real passion and joy about your work. Your students are lucky to have you as a teacher. Anyways, thanks for another great video.
Loved your heartfelt comment too. I think Prof Kipping and the internet will help people like you and me to learn and enjoy our ever fascinating univese even at a later age in life. Thankyou to you and the Professor.
@@vidyatodankar4660
I fully agree. I didn't get a chance to go to college, but I've always loved learning about astronomy and physics. Even though my math skills are sadly lacking! I just remember how a lot of my teachers, made such incredibly interesting subjects seem so dull and boring. Professor Kipping definitely seems like a great teacher, and someone who can motivate his students.
John don't feel bad about not going to college and being just a "Tradesman"...the world needs people like you more than we need so-called educated people who a lot of the time contribute nothing...watch a few vids about college students and see what I mean...Thank goodness for all the trades people who know how to build, fix and make the world a better place...PS...I really enjoy this science stuff too...
@@AlzWorld57 Thank you my friend. So far his videos keep improving every new episode, and I've learned a lot. I also watch Joe Scott a lot. He's much more on the comedy side, but he still has some very good content. I think that learning is always worth it, even if only for your own better understanding of the Universe we find ourselves in!
Excellent work.
I hope you guys find a habitable exomoon soon. It would certainly be one of the most important discoveries of the century!
The Exoplanets Channel thanks, it’s just a matter of when!
Finding exoplanets is hard enough as it is, and it'll be far harder to detect exomoons. Our best hope for finding exomoons might be to find one with a similar planet to moon ratio to Earth and Luna.
The James Webb space telescope could be able to detect some exo-moons
I feel like I discovered a goldmine when I discovered your channel today.
You explain Astrophysics in an understandable way which doesn't hit me with a huge amount of maths that makes my brain hurt. That means I don't need take an Ibuprofen after watching your video. The tablets thank you. And I got the Trek reference at the end.
I was always under the impression that the 'cool' in Cool Worlds means something like 'awesome' instead of 'having low temperature'! :D
You have single handedly helped me attempt to understand the mystery and meanings of the universe. You dont always say the things people want to hear or base your outlook on faith. Even though there is a bit of it in all of us.
Not afraid to give the answer that NO ONE likes to give and that's " i dont know."
I may be rambling about past videos. But you truly have made me inspired to begin to learn about anything to do with time space in a serious note. Thank you Professor.
I Apologize for the grammer.
Prof Kipping, I’ve been subscribed to your channel quite a while, and I have to say, Idk how many people are involved in making your videos here, but being a student of astronomy and physics I fully appreciate everything you are doing it seems like you put so much work into these videos and I must say, I’ve learned so much from them.. Thank u for all the hard work and please keep the videos coming!🪐🌍🔥🔥🔥
You have a way and mannerism of talking about deep and fascinating subjects that is second to no one. You and Professor Brian Cox would be a fantastic get together. Waited up late for this video to drop since your post, epic! Thanks
I love how you quoted Vulcan philosophy at the end!! 😍🥰❤️
“Infinite diversity in infinite combinations” is one of my favourite quotes - it’s such a beautiful concept that beauty, growth, and progress all result from the union of the unlike. That concord, as much as discord, requires the presence of at least two different notes.
The best CZcams channel, for space and planets.
I'm so pleased to have found this channel, thank you so much for not just the content but the passion you present it with!
If it's not something you have considered already, I think a team like this would really benefit from your own distributed computing model; with a growing Cool Worlds community you could potentially see gains in computational power that would otherwise be prohibitively expensive.
This was awesome Prof! I hadn't even thought about exploring exomoons before this video. And now that I've seen you talk about it and thought about it more deeply, it seems like an absolutely amazing field for research. Moons indeed tell us so much about the host planet and consequently the entire star system and seeing as our own system's moons are so damn fascinating, it makes me more excited for what we could find outside!
I really hope the two techniques you mentioned give groundbreaking results, and if not, at least propel the field far enough that more and more people start taking interest in it.
I'm a huge huge fan of your channel!! Top-quality content with a perfectly unbiased and objective scientific take on the topics! Hope you never stop doing these videos!
Cheers!
Don’t be too hard on yourself,Doc .
Your doing what is going to be text book history 200 years from now.
Odds are there will be a planets/moons named Kipping when we finally touch down on them:
Also
Your cat sounded hungry.
I love all the little clips used, and I love even more how there's always links to the source of every single ones. There's always one or two I'm curious about, and it's so nice to always have them right there in the description!
I cant get enough of your content Mr. Kipping. Your videos are mesmerizing and they just lift me up off of my couch and send me thru the universe on an immersive journey and its a nice escape from the global troubles going on today. So we thank you for that.
I have watched many of your videos, and absolutely love the way you're able to communicate these concepts to a layperson such as myself. I wish you luck in finding many exomoons.
Been really excited to see your video on exomoons after hearing about some of your research and also being in the live stream recently :-) this is excellent! The fact that in my lifetime we are you able to detect exomoons is just incredible
These are the Type of videos i get excited when notifications alert me!! Thank you and awesome Material!!
I’m always amazed by the quality of the content you produce. Very clever btw
To think, I never even thought about exo-moons until this video. Yesterday, I didn't even know such a field existed and now today, I'm excited about the possibility of exo-moons existing and am glad that your team is making improvements to your method.
I love this applied deductive reasoning approach to solving large complex problems like this. Very cool!
I love how you explain things with scientific methods but so that everyone can follow... such great content, keep it up and good luck on the hunt! I really hope your efforts will get rewarded soon!
Love the previous comment! Exact same here from Australia. Your videos are a torch and a gift to people all across the globe in isolation of one form or another. Thank you so very much. It brightens my day so much seeing another Cool Worlds Lab video has popped up! Thinking of everyone around our planet today, and all these days. Stay strong, stay home, and wash those hands 🎋🌿🦋
I love this CZcams. Thank you for explaining this information in an intelligent yet easy to understand language. A total pleasure to watch this video. Looking forward to see more.
I’ve grown up with so many spaceal discoveries that I feel blessed, there are so many more wonderful things out there to learn about yet as the years past and I get old and where once I wanted to learn and know everything I find that now I’m blessed with more Earthly treasures , my family, kids and grandkids. This may sound depressing but if I become a victim to this ongoing medical crisis then I am ready to pass on , I’ve learnt the wonders of the solar system and felt the love that family provides. I’ve nothing left to want or need so yes the universe has many more secrets to share but those can be bewilderments of another generation, I just hope that there are young’ens that will too look upwards in awe as I once did .
Be safe everyone . R .
Every time I heard the voice of Prof Kipping I remembered Carl Sagan, then realized he a Carl Sagan Fellow and perfectly the right heir to the legend.
Wowzers! Thankyou so much for taking the time to put out these videos to share with us and with such clarity of explanation.Truly inspiring.You and your team rock! :-))))))
Thanks for this amazing video and the super interesting lesson on TTV's and TDV's as a tool for eliminating impossible moons, I look forward to hearing of this "even more powerful tool" soon. Well done with your progress towards the first discovery of an exomoon and in doing your part in keeping my and many others imaginations fueled!! Much gratitude!
Moons in the Python system: "I'm not killed yet! I'm feeling better!"
As usual another great & interesting video by Pro David Kipping!
Like the video, very informative, but loved your honesty the most! Best of wishes on your next theory and/or thesis!
Love this channel, and these videos are a nice escape from our current stay-at-home-civilization status.
It's an amazing channel. Every time I came here, there seems to be a lot to learn and always something new that I never thought of. Detecting planet with a moon by observing them wobble is truly something new to me. Now I hope my house or furniture would wobble too to give me a sign of where is my missing TV remote or toys that been lost over the years. Keep up the great contents..!
More great content, so happy I found this channel (better late than never, after all). Keep up the good work.
Great to see the new post, Professor. Hoping you and your team are well and healthy. Stay safe!
We are thanks! It’s hard being away from them all but we’re getting through with Zoom, stay safe yourself!
Question : Does the new paper assume the number of moons? Won't the timing differences change with to multiple moons in orbit?
There are multiple ideas about multiple exo-moons.
1) A lot of planets are larger planets which have more probability of having more moons, like jupiter or saturn. I'm not saying it should be that way, but it is just a higher probability. For example mars is smaller, has more moons than earth.
2 ) A lot of moons orbit in a resonance pattern, where they might be able to show compounded effects like a total periodic increase or decrease in the timing effects. Is that taken into account?
This was a really cool video, happy hunting.
Thank you for always furthering my interest of the unknown. Its incredible. If I have a bad day I can literally watch your video's and forget about my problems for a little while.
I am glad that I have discovered your channel. This is one of the best in the genre.
Proving that this and this exoplanet does not have a moon is a great contribution in itself.
I came across your Chanel searching for new videos about space and the universe. I absolutely love everything about the universe and have a special place in my heart for black holes. I have to say that your videos have been enchanting. Your engaging, brilliant and your love of all things universe comes across in a wonderfully hypnotic way. I'm in awe of your knowledge.I've learned so much and you've really opened my eyes to how much more amazing it can be to learn about all aspects of it. Even the subjects I felt were beyond me. You do it in a way that a layperson like me can even understand. I look forward to all your videos. Thank you so much for your time, hard work and for your contagious spirit. Although now that I have binged all your videos I'm starving for more. It's exciting waiting for the next topic to learn about. Again, THANK YOU. Can't wait for more.
David has the perfect voice for these videos. So soft and soothing. Great content and super easy on the eyes ;)
Your videos are fantastic and the tone of your voice carries you even more ... fantastic. Correct communication is already in itself everything.
You strike me as an extremely real, genuine person. I really enjoy your content. Best wishes to you and your research! You're bringing wonderful knowledge and perspective to a lot of people and that's a wonderful thing. Thank you so much!
I love your sincere passion for this stuff dude. Makes me love you like a brother, and fellow child of the stars.
Thanks for these videos. I love the subject and you make it easy for the rest of us to understand the universe better without unnecessary fanfare and glitter. Your presentation is absolutely engaging and a big thanks to your team too.
very interesting video david! doing my thesis now as we speak and trying to get inspiration. hope you and your family is well in this difficult time of covid19!!
I love going back and watching them again. Over and over.
You have a way of explaining highly technical subjects in such a way that it is understandable, for which I thank you. Also a brilliant video to start off my Easter Sunday. Stay safe :-)
God I love this channel, thank you so much for talking about your work! Every video is fascinating. Love the Star Trek reference at the end :)
I’m pretty sure there was a reference to Blob Forward’s Flight of the Dragonfly somewhere around 10:15 when he was talking about the Pleiades supercomputer’s part in The Martian. As a Trekkie, I appreciate those references, but the more esoteric bits of sci-fi really feel special.
I really enjoy your videos, great commentary and visuals, keep up the good work!
This channel is worth supporting. It's a balm of reason in crazy times.
Professor Kipping, thank you a lot for your work done both in research and in divulgation of the exploration done by your team.
I appreciate the knowledge and theory you present in this channel, but what I appreciate the most is the sample of a researcher's life and work, that let me have a taste of real challenges, work arounds, and breakthroughs done by researchers in science, and especially the mindset needed to do these tasks.
This is something that I don't have contact yet as I'm still an undergraduate, but your report on your work is a splendid appetizer of something that I want to be a central part of my life.
This is amazing. You're literally changing the game up massively. And we get to see it on CZcams. It makes it far more understandable and personal.
Where else would you find a CZcams video?
"The more eyes we have on the prize to try to look for these things, the better our chances for success". You seem to be the prize of a teacher ! Between your love for what you do and your, let's say delivery, you can keep the interest going for those who have even the slightest interest on what lies beyond. it almost sounded like you underestimated yourself once or twice. Please don't because throughout the rest of the video was optimistic. You mentioned descendants. I wish everyone would think about them. I personally do not have children but I have nephews and cousins and my cousins children, some I don't even know but I think about them ( big family ). I hope this virus teaches us something, like thinking about the world and the Human race as one so maybe one day we can get to some of these moons.
John Di Francisco Very well put. I relate totally as I have 13 nephews and nieces.
We need to appreciate and value this period of time given to us, to reflect on our humanity,
and what we can do to embetter ourselves, and think outside the box, for more research and doscoveries, exomoons and other treasures in the universe.
Take care, stay safe.
I dont know how i found you but im glad i did. You certainly provide a great deal to think about
This channel is fascinating.
I'll admit to not understanding much of it, but surely that's the point of trying to learn new things.
Loved it, It is amazing that we are on the cusp of detecting exo-moons now!
Keep doing your videos. I’m learning more with each video.
A couple of quick thoughts:
1) While exoplanet discovery is well under way, refinements are inevitable. Exoplanet scientists have a lot to look forward to. Probable future features include:
1.1) Increasing details such as rotation period and direction, atmosphere details (some limited availability now), surface details, and core details (hot or cold, magnetic field strength, etc.)
1.2) Increasing details about whole solar systems (number of planets, their orbits, etc.)
1.3) Detection at increasing distances from Earth.
1.4) Detection in increasingly "difficult" orientations of the orbital plane relative to the viewing angle from Earth.
2) (Here is where I get myself in trouble and really display my ignorance) It seems to me that planetary motion is primarily circular motion (Okay, Most orbits of planets are slightly elliptical). As such, a Fourier analysis of the wobbles could help sort those wobbles. And Fast Fourier Transforms are just that.
2.1) Wobbles at frequencies higher than the planet's orbital period will either be smaller masses closer to the sun, or moons.
2.2) Wobbles a frequencies lower than the planet's orbital period are likely masses orbiting further from the sun.
2.3) There will, of course, be noise. (improved instruments will help, but those take a lot of time and money to put into operation)
2.4) Data reduction such as taking derivatives (obtaining the rate of change) or running averages (for smoothing), or playing with peak-finding algorithms can make some events "pop." (but you have probably tried these and more.)
Anyway... be very afraid that there are people "out there" with little knowledge and loads of interest. Proof? The above.
Great work prof. Fine explanation ...keep it up
Someone watched 95 Worlds and Counting! Thanks man your voice and video work is a great combination. Thanks
Wow... that introduction is literally a sci-fi movie so fansinating. Great job!
Hello mr. Kipping,
I just wanted to say that I really like your videos, when I was younger I was supposed to become an astronomer, but in the end I forgot my interest and chose a different career.
Your videos have fed my curiosity on these subjects again, I've enjoyed watching them a lot! Thank you! :)
Great video. Keep posting.
David you are great. I have no doubts you will one day find the way to show us those fancy exo moons lost out there.
That love and this passion for the universe is remarkable. The ability to giving the average mind to understand whats happening with simple words. Only one person i admire for that, the Carl Sagan. Now and you, doc. Greatings from Greece.
16:30 The Kepler Orrery. One of those classic images that you just can't forget. It would make great wallpaper.
Am glad i joined this unique channel . Ur saying everything that comes to my mind ..
His voice is like it's made for giving people chill while talking about science stuff
Thank you for your work!
We discussed this paper in our exoplanet journal club at UCLA. Interesting work!
3000 possible planets and moons out of 10^12+ I think there are still some discoveries to be made.
Excellent video. Interesting is the reference to the concept of Lagrange points
I love how you've applied such a simple methodology to get such great results - process of elimination. I don't think the "gold rush" era of exoplanet discovery is behind us. We still have so much to learn about planetary systems and considering how many stars are out there, our sample size is still *so* small.
Theres obviously a ton of moons around planets far and wide, it took centurys for humans to detect our own we can argueably be still at our Galileo stage on the much grander distance we now behold.
Hey was nobody looking up for a few centuries and then some one spotted our moon
james gilbert I think they are referring to the other moons around other planets within our own solar system.
@@Jameson1776 I im talking about Antonis comment he said our own not others
Mission subscribtion accomplished! Nice vid! 👍👍👍🥇💎
This channel is amazing the best content and the presentation is the best I’ve seen keep up the amazing work 👍
Prof. Kipping, I have enjoyed your videos for quite some time and this video was inspiring for me. The fact that you took responsibility for a "Failure" but I don't believe your team did. Edison once said, "Great success is built on failure, frustration, even catastrophy." Congratulations on your finding of the theoretical exo-moon
Excellent video!!!
Wonderful video! When I was kid, I read that "though we know planets outside of our solar system should exist, we can't be use, and we haven't seen even one". The situation has been changed since then, but now history seems to repeat again, this time with exomoons instead of exoplanets. And btw, the grammar checker in my web browser should know the works "exomoon" to be correct too, since it knows about "exoplanet" :) I wish I would be younger now, back to the old days I wrote programs for my Commodore 64 (yes, in BASIC, haha) trying to simulate solar systems (including our one for sure) with gravitational interactions using the well known Newton law, though I miserably failed with that (no wonder, I was so naive ...), but anyway :) At least the enthusiasm was there. And somehow I felt some kind of similar feeling while watching this video right now. [oh, and sorry for my bad English ...]
this is a great way to communicate your ideas in your paper to a wider audience. After watching your video, I am not sure why exo-moons is not a hot topic in your research community. Sounds pretty fun to me.
This supercool video is just what I needed during lockdown ☺️.
Yes!
The most interesting thing about this, to me, is that these constraints aren't saying that these planets don't have moons - just that the data isn't good enough to use it for detecting them. In fact, it would be quite rare for planets in a star system to have no moons whatsoever.
Nice upload 👌🔭
Really your voice makes my anxiety decreased. And makes me sleep.
I’m glad I can help
I'm the only scientific mind in my circle of family and friends and Cool Worlds has giving me a outlet.... Subscribed, Outstanding videos lad. Keep em coming!!!
Good content to watch especially in Isolation
How can one man have such a beautiful mind *and* voice at the same time?
Some of the moons are nothing but tiny boulders. They need to redefine what a moon really is like they did Pluto beings a planet.
I'm learning so much about science ;) I think everyone on the planet needs to know and understand these concepts . thanks David your the best !
I like the way you explain everything.
good luck
I LOVE THIS CHANNEL COS OF SOOTHING NARRATION AND FANTASTIC SUBJECTS
This is so cool! I would love to be on this team.
Really good!!
I am so grateful (to whomever) that I discovered Cool Worlds a few months back. Two years ago today I left society for five months because of Covid and because I could. When I came back, I was depressed. I had lost several friends and a member of my family, to either Covid, suicide, or simply time. While on the island, I found Neowise, with my own eyes. (Even though I had a pair of binoculars hanging on my neck, using my Dad's teachings). It was so dark and beautiful, for the first time I saw colors in the Milkyway. Your knowledge, Dr. Kipping, Is obviously deep. Your Gift of communication and your tenacity towards and focus on your vision is Inspiring. Even if you had not gotten the Carl Sagan scholarship, I know that if my father was alive and watching your programs with me, we would both be saying "that guy reminds me of Carl Sagan". Thank you.
Great video! I hope that one day in the not-too-distant future we'll have technology that will allow us to image exomoons and their host planets in high-definition resolution without having to send a space probe on a fly-by mission that would take thousands of years. If we could image exoplanets and moons in HD, we might also be able to observe their physical features such as geography and topography. It would be fascinating to see if any of them share any resemblance to Earth. There is so much diversity just in terms of the planets and moons that exist within our own solar system, so just imagining the infinite diversity of potential worlds out there is inspiring.
