Dr. Becky, I really like that you add photos of the papers' authors. It's a nice touch that helps us see the humans behind the science. Thank you for taking the extra time for this.
I do as well...it shows that real scientific information is developed by individuals following scientific methods...and it takes a lot of time, collaboration, and willingness to try new things
So sad not to see Wolszczan and Frail not receiving half of the prize. Not only they had results 5 years earlier, and with incredible precission accuracy in their model, but also did change so many things about understanding of planets around stars in general.
As an astro-muggle, I've seen loads of these stories as they skated by over the years but *really* appreciate hearing them all strung together into a story like this. Many thanks.
*Tip for English speakers* - Polish _w_ is English _v_ - Polish _sz_ is English _sh_ - Polish _cz_ is English _ch_ Therefore the last name of Aleksander Wolszczan should be pronounced as _Volshchan_ 😉 Greets from Kraków to all of you 😃
Is it Volsh-chan, two syllables? I had to look it up for myself, even before I sent the the question, but I am still curious if you can verify that this is how it's pronounced. upload.wikimedia.org/wikipedia/commons/b/b3/Pl-Aleksander_Wolszczan.ogg It sounds as you describe. I ask because I see Polish names almost every day and I always feel as if I may be pronouncing them wrong, but I realize I have been saying them correctly most of the time, only because I've heard most of them pronounced by other people before attempting to say them myself. Thank you for this post.
@johnmburt1960 It's Sta-nee-swav Lem. Letter "Ł" is in his first name, not surname. (Stanisław Lem). And last syllable is pronounced like "swath" (www.merriam-webster.com/dictionary/swath.)
Your channel has really been my favorite recent astronomy channel. Consistently great content ever since you started regularly making videos. Thank you!
When I was a kid all my astronomy books said that there were surely planets orbiting other stars but they would be so faint that they could never be detected. I was born in 1966.
@@ian_b I have a book about astronomy/space stuff, published in the late 60s, that my grandfather has left me. It's both amusing and humbling to compare where we were back then to where we are now. The book lists all of earth's satellites on one single page.
Dr. Becky, I have been an amateur astronomer since the late 70s. Thank you for the programs. They are well done and an excellent bridge between the amateur and professional world. I wish this kind of material was avalable back when I entered the hobby. It is amazing how much astromomy knowledge has grown in the past 40 years.
Born in 1990? Thank you for making me feel ancient, Dr Becky! 😭 What I'm taking away from this is that Newton looks uncannily like TV presenter Jeremy Vine.
This may be your best video yet. I am in awe of your amazing distillation of 14,000 + papers, and in a wonderful example of the highest practice of human thought, build a case and lead us convincingly to the conclusion of the Nobel committee, all the while, informing us mightily along the way.
Yes I didn’t mention that but there’s a huge body of work looking into habitable exomoons now that the first detection of an exomoon has been made! 👍 exciting stuff
And it's worth bearing in mind that two of the most promising potential hosts of life outside Earth in our solar system are Europa and Enceladus, both well outside the Sun's habitable zone.
Just to nitpick : Didier's name is pronounced Kelo, not kweloz. Also I would have expected you would have talked about how the discovery came to be. If you search for Mayor's publications on the ADS, you see he was in stellar radial velocity (but wrote a 1988 paper titled "a giant planet beyond the solar system ?" ). Geneva observatory had (still has in fact) a 1m telescope at OHP, and they were using Coravel to measure the radial velocities of stars. Then the use of fiber optics to link the telescope to the spectrograph (i.e. no more flexure while the telescope tracks during the night) and the thermal stabilization of the spectrograph allowed to go from km/s to m/s precision, and therefore the detection of Jupiter like planets. I used to work at La Silla Observatory before the HARPS spectrograph (2000-2003), and the former spectrograph was in a thermal stabilized room below the 3.6m telescope. If you just opened the door of that room, measures were bad for 2 days. It's really very high precision stuff (HARPS is in a vacuum chamber). Other than that another very good youtube video. As usual :).
The first known helio-centric cosmological model was proposed by the great ancient Greek astronomer and philosopher Aristarchus (~400 BC). One of the main reasons Aristarchus's model was not adopted at the time was that Aristotle didnt accept it. In fact Coppenicus's initial draft of his helio-centric model referred to the Aristarchus model, but was edited out in the first printing of the Coppenicus's book.
I have heard that the reason (Aristotele’s reason?) why the heliocentric model wasn’t accepted was because they didn’t see any parallax in the stars. The thinking went that if the earth was moving there had to be some parallax observable in the sky which there wasn’t. They thought that in order for the heliocentric model to be correct the stars had to be so far away that such distance was impossible.
@@pansepot1490 That is a possibility. But just as in recent times, there were religious pressures and superstitions that made a non-geo-centric cosmos unpalatable and even heretical in nature.

@Raging S Interesting. Do you have reference or source? I am not familiar with this interpretation of Aristarchus's work. My understanding is that Aristarchus of Samos maintained until his death that the Earth revolved around its axis and orbited the sun.
Speaking of the Nobel Prize, I can hardly wait for you to publish your landmark tome: Philosophiae Naturalis Principia De Unguiculis Metalli Perpoliendi Pro Bono Physiciorum (The Natural Philosophy of Fingernail Polishing for Scientists).

@@DrBecky Glad my comment fulfilled it's intended purpose Dr. B. Remember that Nobel Laureates have to deliver a presentation on the topic for which they were awarded their prize. Maybe when your talk ends and the scientists shuffle out of the room, their eyes will be dry but I bet their fingernails won't be.
@@Biomirth Well, . . . ya, that goes without saying. Come to think of it; I've never said that. So it must be true. I think the good doctor would do better to discuss her famous Becky Uncertainty Principle: "You can know the position of the fingernail, you can know the speed of the fingernail painting brush but you can't at the same time know whether the colour in the Revlon bottle will match your apparel." This principle should not be confused with the Becky Exclusion Principle which states: No one fingernail can be two different colours at the same time. Finally, there is the Becky's Cat Experiment. This is more a thought experiment than anything else. You will see why presently. It goes like this: If Dr. Becky takes her cat and paints 1/2 his nails with fingernail paint and the other half with catnip and then puts him in an enclosure that is air tight and non-transparent, the cat will be in a state of quantum superposition (Not surprising, cats always think they are superior). There will be a cat that is normal and a cat that is totally drunk from the fumes of the fingernail paint and catnip. When she opens the top of the enclosure she will fall down laughing at the antics going on in the box. This happens because she has collapsed the Behave Wave (and herself). The cat must behave according to the laws of biochemistry (i.e. totally intoxicated). Hopefully, you can see that this is only a thought experiment because any real cat would claw or gnaw halfway up your arm if you tried to paint its nails. The real mystery is what happened to the other cat in the box? Who stole the other cat? It can't have disappeared. Physics tells us that matter can't be created or destroyed (cats can only be neutered or spaded). I suspect the cat will show up someday and I wouldn't be surprised if some of the scientists at her Nobel Prize presentation didn't console her with this information. Even so, I think it would still be worth her while to put a picture of the missing cat on posters and on milk cartons. By the way, does anyone know if this 'disappeared' cat would be made of antimatter. If so, maybe the poster/milk carton idea is a bad one.

So I'm passing away soon from pancreatic cancer and I've got one last wish. Would you and Anton Petrov pretend to be my mom and dad? I want awesome bed time stories, please?
OK, this is the second video of yours that I've watched....you explain this stuff so well! I wish my high school physics teacher had your energy. I might have done better in school:(
Thank you for this video! It is a very interresting review of the history of the research of exoplanets. A friend of mine once told me, that he was attending a conference, where everybody was talking about the possibility of detecting an exoplanet. Everybody assumed, that every planetary system would reseble ours, and then somebody put a slide on the overhead projector "Planet detected around 51 Pegasi..." and everybody in the room realized instantly, that all their asumptions were rubbish. I remember this story very often. I am starting to work on a lection about aliens, and it reminds me, to always expect the unexpected... Once more: thank you very much!
Dr. Becky, I really enjoyed "Space: 10 Things You Should Know" in the audiobook version on my daily commute. But only like two hours of play time?! Come on, you can´t just get people hooked, and give them only two hours of astrophysics awesomeness! Give us more, please continue writing books for the greater public!
Subscribing to your channel has been the best thing ever. Thanks so much for making these informative videos!!!!! I love learning and you make it so fun and easy to follow! ❤
love your videos! and your communication enthusiasm! don't know if you'd want/can correct this, but @ 15:45 we're introduced to a picture of David Charbonneau and again @ 16:44. However, @ 17:04 the same person/photo is captioned as “Drake Deming”.
Exoplanets are not designated 'b', 'c', 'd', etc based on their distance from their host star but by the order of their discovery ('b' first). Only if two or more are discovered at the same time is the distance taken into account. For instance, the planets orbiting 55 Cancri are (in order of their nearness to the star) 'e' (discovered 2004), 'b' (1996), 'c' (2002), 'f' (2007) and 'd' (same time as 'c'). 55 Cancri is actually named Copernicus and the planets are named Janssen, Galileo, Brahe, Harriot, and Lipperhey. 51 Pegasi is named Helvetios and 51 Pegsi b Dimidium. PSR1257+12 has the name Lich and its planets Draugr, Poltergeist and Phobetor. In works aimed at the general public you might want to consider using their names as well as their catalog designations.
Okay, yes, the unbroken chain of discovery that is the tradition of the scientific method that led to our discovery of exoplanets is cool and all BUT THAT SHIRT THOUGH IS TOO CUTE.
This is all so frustrating. Imagine seeing an entire continent across an ocean that you could tell was full of magic and unlimited wonder but knowing that you could never sail to it because of the restraints of physics. I guess it's like the saying goes; "Born too late, born too early." Have you ever considered doing an AMA?
Dr Beccy, Aristarchos was possibly the first to express the Heliocentric model. The Antikythera mechanism just proves that Kepler just read prior theories. Give credit where it belongs. Thank you
Thank you so much! I really love the quality and research that goes into your videos. Even though I am in a completely different field of research, your videos make me understand and spark my interest in the universe!
She pronounces this name totally wrong tho. rz is a single sound, it is not r-z, but instead something like a first sound of the name Jeannette / Janet. A bit strong than giant, or badge.
Brilliant techniques those historical late active scientists accomplished, even more astonishing, was how they were, so ahead of the technology to attempt these celestial investigations, like they forgot, what time of century they lived in.
Fascinating backstory to the discovery of the first exoplanet. Has there ever been an attempt to construct a model of the Sun showing the 'wobble' caused by the orbits of our several planets? I imagine it would be quite irregular due to the different orbits.
FYI, Francis Peyton Rous had to wait 55 years for his Nobel. The Prize was awarded to him in 1966 for work he had done in 1911. He was ridiculed at first for the idea that cancer could be infectious, but the world eventually came around. Scientists all too often act like just plain folks.
Thank you for not using "meme" video clip inserts like you have done in past videos! I'm ashamed to admit that 90% of the stories in this video were unknown to me. I do though remember when Hubble had mirror problems and the "government does best when government does least" adherents were as giddy as can be.
Thank you, Dr. Becky, for a fascinating and impressively thorough discussion of this topic! Interesting to know how far back humankind was thinking about these things...
That was the picture he had on his official website - I couldn’t find a single one of him anywhere on any academic university website either. So I figured why not include it! 😂
Becky, your outtakes are hysterical!! Thank you for another informative and enlightening lecture. We are truly on the cusp of learning about exoplanets. There is so much more to learn, The fact that there are planets around a pulsar is amazing. How it occurred is a real question. Along the lines of unanswerable questions... Why does toast always land jam side down when you drop it? So, Thank you for your time to make this video Clear Skies, God Bless
Great summary of a field that has just exploded in recent years. Thank you for making this video. At 17:03, you have David Charbonneau's picture above Drake Deming's name. I think Drake, Joe, and Sara would all find this very humorous.
@@johnobrien4367 Yes, actually, it is! I've experienced a lot more of history, including astronomical history. For instance, when I was a schoolboy, the encyclopedia listed just 31 known planetary satellites. I think the latest such addition at the time was either the 1948 discovery of Nereid by Harold C. Urey, or the 12th known satellite of Jupiter. The Pioneers & Voyagers in the 70's & 80's took us from a few more than that, to much more than that, and the list is still growing! Also back in my school days, I recall the launch of Sputnik, and with it, the dawn of the Space Age. It's been an incredible ride, and it's only getting better! Fred
Love your show! You smile-maker you! (The intro I knew from Carl Sagan's Cosmos, which I watched in my teens, that episode where he goes to a school to explain the kids about the methods of planet-hunting, and how during their lifetimes, in the near future, they'd witness those discoveries).
It could be fantastic if you could choose an object in the sky and then show pictures of it, made over time with different telescopes. From the first drawings to the clearest image we have today from an earth telescope. :-)
Starting in 1593, Bruno was tried for heresy by the Roman Inquisition on charges of denial of several core Catholic doctrines, including eternal damnation, the Trinity, the divinity of Christ, the virginity of Mary, and transubstantiation. Bruno's pantheism was not taken lightly by the church,[5] nor was his teaching of the transmigration of the soul (reincarnation). The Inquisition found him guilty, and he was burned at the stake in Rome's Campo de' Fiori in 1600. After his death, he gained considerable fame, being particularly celebrated by 19th- and early 20th-century commentators who regarded him as a martyr for science, although most historians agree that his heresy trial was not a response to his cosmological views but rather a response to his religious and afterlife views I had to check on it. Maybe you should have made this part about his execution clear as well.
"This was the first multi-exoplanet system found..." (15:12) I assume that means "found around a main-sequence star." Earlier, the discovery of three planets orbiting a pulsar was mentioned.
Dr. Becky, Has there ever been any research done into the likely hood of life on these planets that would have the presence of water? Further, would the size or gravity level of the planets dictate the probability of them being able to leave their own planet (if they were a space faring civilization). Thought behind that was if there was a super Earth X.0 found but it happened to be twice or more the size of earth but showed definite signs of water or even life (detection of non-natural chemicals in the atmosphere), would the size or relative gravity level of that planet dictate the likelyhood of them breaking orbit or even achieving flight?
Dear Dr. Becky, you make Astrophysics very interesting and understandable! I enjoy your videos. OK........I also love your accent and you're quite very attractive! LOL! This video on exoplanets is very interesting!!
One thing about these exoplanet findings that troubled me was that they all seem to focus on 1 planet. Granted, I know nothing about the calculations involved or the detection methods. I'm a civil engineer ffs and way out of my lane. It's good to know that the experts are considering multiple planet systems.
Dr. Becky, I really like that you add photos of the papers' authors. It's a nice touch that helps us see the humans behind the science. Thank you for taking the extra time for this.

So I'm passing away soon from pancreatic cancer and I've got one last wish. Would you and Anton Petrov pretend to be my mom and dad? I want awesome bed time stories, please?
Also love your version of The Buggles' classic hit from 1979 :)
OK, this is the second video of yours that I've watched....you explain this stuff so well! I wish my high school physics teacher had your energy. I might have done better in school:(
Did anyone else just love the way Dr Becky says "sun"? It's a very peculiar observation but I love it anyway
Thank you for this video! It is a very interresting review of the history of the research of exoplanets. A friend of mine once told me, that he was attending a conference, where everybody was talking about the possibility of detecting an exoplanet. Everybody assumed, that every planetary system would reseble ours, and then somebody put a slide on the overhead projector "Planet detected around 51 Pegasi..." and everybody in the room realized instantly, that all their asumptions were rubbish. I remember this story very often. I am starting to work on a lection about aliens, and it reminds me, to always expect the unexpected... Once more: thank you very much!
I loved this summary of the history of exoplanet discovery, and love your organization of thought. Thank you!
Hans Bethe won the Noble Prize in 1967 about 28 years after his work on stellar evolution in 1939.
Dr. Becky, I really enjoyed "Space: 10 Things You Should Know" in the audiobook version on my daily commute. But only like two hours of play time?! Come on, you can´t just get people hooked, and give them only two hours of astrophysics awesomeness! Give us more, please continue writing books for the greater public!
Haha! I’ll try and make my next one longer 😂
Great video. Thorough, fun and easy to follow.
Thanks to you I've now got video killed the radio star in my head!
I love your long form style videos. This is a fantastic way to talk about this years Nobel prize. Great job!
Also your shirt is cute AF!
Thanks Joseph 👍
Subscribing to your channel has been the best thing ever. Thanks so much for making these informative videos!!!!! I love learning and you make it so fun and easy to follow! ❤
love your videos! and your communication enthusiasm! don't know if you'd want/can correct this, but @ 15:45 we're introduced to a picture of David Charbonneau and again @ 16:44. However, @ 17:04 the same person/photo is captioned as “Drake Deming”.
Exoplanets are not designated 'b', 'c', 'd', etc based on their distance from their host star but by the order of their discovery ('b' first). Only if two or more are discovered at the same time is the distance taken into account. For instance, the planets orbiting 55 Cancri are (in order of their nearness to the star) 'e' (discovered 2004), 'b' (1996), 'c' (2002), 'f' (2007) and 'd' (same time as 'c').
55 Cancri is actually named Copernicus and the planets are named Janssen, Galileo, Brahe, Harriot, and Lipperhey. 51 Pegasi is named Helvetios and 51 Pegsi b Dimidium. PSR1257+12 has the name Lich and its planets Draugr, Poltergeist and Phobetor. In works aimed at the general public you might want to consider using their names as well as their catalog designations.
Okay, yes, the unbroken chain of discovery that is the tradition of the scientific method that led to our discovery of exoplanets is cool and all BUT THAT SHIRT THOUGH IS TOO CUTE.
This is all so frustrating. Imagine seeing an entire continent across an ocean that you could tell was full of magic and unlimited wonder but knowing that you could never sail to it because of the restraints of physics. I guess it's like the saying goes; "Born too late, born too early."
Have you ever considered doing an AMA?
Yup! I was thinking of doing one to celebrate 50,000 subscribers, so almost there!
Dr Beccy, Aristarchos was possibly the first to express the Heliocentric model. The Antikythera mechanism just proves that Kepler just read prior theories. Give credit where it belongs. Thank you
Thank you so much! I really love the quality and research that goes into your videos. Even though I am in a completely different field of research, your videos make me understand and spark my interest in the universe!
Dr. Becky - a channel that mainly gives you two things: A lot of knowledge about astronomy and great earworms!
14:48 - Sylvain Korzennik looks an awful lot like Binky from Life In Hell.
She pronounces this name totally wrong tho. rz is a single sound, it is not r-z, but instead something like a first sound of the name Jeannette / Janet. A bit strong than giant, or badge.
Brilliant techniques those historical late active scientists accomplished, even more astonishing, was how they were, so ahead of the technology to attempt these celestial investigations, like they forgot, what time of century they lived in.
Fascinating backstory to the discovery of the first exoplanet. Has there ever been an attempt to construct a model of the Sun showing the 'wobble' caused by the orbits of our several planets? I imagine it would be quite irregular due to the different orbits.
Thank you for this historical review.
Must have been quite some work 🙏
Fascinating look at exoplanet history. Thank you.
FYI, Francis Peyton Rous had to wait 55 years for his Nobel. The Prize was awarded to him in 1966 for work he had done in 1911. He was ridiculed at first for the idea that cancer could be infectious, but the world eventually came around. Scientists all too often act like just plain folks.
Thank you for not using "meme" video clip inserts like you have done in past videos! I'm ashamed to admit that 90% of the stories in this video were unknown to me. I do though remember when Hubble had mirror problems and the "government does best when government does least" adherents were as giddy as can be.
"After a few 'minor' teething problems with its mirror..." I love this. They must have just given it a really expensive pacifier. LOLs Cheers, Russ
Love watching your videos! Your passion for your field of work comes through in your excitement when presenting the material.
That Nimbus 2020 looks like a slick bit of kit.
I'm sure a Nimbus 2020 will take us to Proxima and back in notime.
Fine work! I'll save this one for future study. Thank you Dr. Smethurst.
@14:49, science certainly is a serious business. If You don't believe me just ask Sylvain Korzennik ;)
Thank you, Dr. Becky, for a fascinating and impressively thorough discussion of this topic! Interesting to know how far back humankind was thinking about these things...
The Hubble Space Telescope became instrumental... A lofty goal for an instrument. :)
'video killed the radio star' came out a full 10 years before Dr. Becky was born and Hubble was launched. Oh God I'm OLD.
Sylvain Korzennik looks so relaxed 😅
That was the picture he had on his official website - I couldn’t find a single one of him anywhere on any academic university website either. So I figured why not include it! 😂
@@DrBecky Are David Charbonneau at 16:45 and Drake Deming at 17:03 identical twins? They look awfully similar!
Fascinating stuff. The variety of exoplanets and the methods of discovery are almost as numerous as the odd names of astronomers and astrophysicists.
Becky, your outtakes are hysterical!!
Thank you for another informative and enlightening lecture. We are truly on the cusp of learning about exoplanets. There is so much more to learn, The fact that there are planets around a pulsar is amazing. How it occurred is a real question.
Along the lines of unanswerable questions...
Why does toast always land jam side down when you drop it?
So,
Thank you for your time to make this video
Clear Skies,
God Bless
Beautiful the way you explain! Greetings from Costa Rica 🇨🇷 🎶🎵 Saludos cordiales!
Absolutely addictive way of presentation! Thank you
27:17 oh my celestial sightings! Love that Harry Potter T-shirt, with that ancient gismo geo-scoptical tention rod! (Broom craft).
Maybe I am a Fan-Boy but your content is World/Life changing. i.e. very informative.
Have you heard that exobiologists recently discovered camels outside the Milky Way? Yup, camels! In the Andromedary Galaxy.
LOL good one!
Great summary of a field that has just exploded in recent years. Thank you for making this video. At 17:03, you have David Charbonneau's picture above Drake Deming's name. I think Drake, Joe, and Sara would all find this very humorous.
When you consider that most of these planets might also have moons...
Time to refresh my knowledge on the Fermi Paradox
It's only a paradox if you're not looking for Vogon-sized fleets.
I like the picture for Sylvain Korzennik.

And here's me looking at retirement in less than 2 years. Just rub it in a little bit more.
Take heart. I've been retired for 13.
Fred
Isn't it nice being old enough to be her grandparent?@@ffggddss
@@johnobrien4367 Yes, actually, it is! I've experienced a lot more of history, including astronomical history.
For instance, when I was a schoolboy, the encyclopedia listed just 31 known planetary satellites. I think the latest such addition at the time was either the 1948 discovery of Nereid by Harold C. Urey, or the 12th known satellite of Jupiter.
The Pioneers & Voyagers in the 70's & 80's took us from a few more than that, to much more than that, and the list is still growing!
Also back in my school days, I recall the launch of Sputnik, and with it, the dawn of the Space Age.
It's been an incredible ride, and it's only getting better!
Fred
Love your show! You smile-maker you!
(The intro I knew from Carl Sagan's Cosmos, which I watched in my teens, that episode where he goes to a school to explain the kids about the methods of planet-hunting, and how during their lifetimes, in the near future, they'd witness those discoveries).
It could be fantastic if you could choose an object in the sky and then show pictures of it, made over time with different telescopes. From the first drawings to the clearest image we have today from an earth telescope. :-)
Thank you so much, your videos are always fascinating and super funny.
Brilliant! Fascinating historical path! Great video!
Starting in 1593, Bruno was tried for heresy by the Roman Inquisition on charges of denial of several core Catholic doctrines, including eternal damnation, the Trinity, the divinity of Christ, the virginity of Mary, and transubstantiation. Bruno's pantheism was not taken lightly by the church,[5] nor was his teaching of the transmigration of the soul (reincarnation). The Inquisition found him guilty, and he was burned at the stake in Rome's Campo de' Fiori in 1600. After his death, he gained considerable fame, being particularly celebrated by 19th- and early 20th-century commentators who regarded him as a martyr for science, although most historians agree that his heresy trial was not a response to his cosmological views but rather a response to his religious and afterlife views
I had to check on it. Maybe you should have made this part about his execution clear as well.
I remember playing EVE and checking light data for transits. Was neat. And a great collaboration on the games part.
"This was the first multi-exoplanet system found..." (15:12)
I assume that means "found around a main-sequence star." Earlier, the discovery of three planets orbiting a pulsar was mentioned.
Enjoyed this discussion of the related discoveries around the Nobel prize for this year. I do enjoy your interests and curiosity, keep it up.
There was a question in that last comment. Are you an encyclopedia? Do you actually remember all of this? I like this video.
To be honest Lich and it's three planets Draugr, Poltergeist, Phobetor really don't get quite as much attention as they deserve.
Good account of the history of exoplanet research. Useful as a reference, good job!
The main chemical substance on the surface of Mars is carbon dioxide.
Eric Wilcox, who worked at the science centre at Jodrell Bank told me that.
Thank you Dr. Becky.
Another lovely video Dr. Becky. Thank you!
Dr. Becky, Has there ever been any research done into the likely hood of life on these planets that would have the presence of water? Further, would the size or gravity level of the planets dictate the probability of them being able to leave their own planet (if they were a space faring civilization). Thought behind that was if there was a super Earth X.0 found but it happened to be twice or more the size of earth but showed definite signs of water or even life (detection of non-natural chemicals in the atmosphere), would the size or relative gravity level of that planet dictate the likelyhood of them breaking orbit or even achieving flight?
I like Dr Becky singing Video Killed the radio Star by The Buggles, a hit tens years before she was born. I feel old...!!!
Dear Dr. Becky, you make Astrophysics very interesting and understandable! I enjoy your videos. OK........I also love your accent and you're quite very attractive! LOL! This video on exoplanets is very interesting!!
Bruno was disliked for FAR more than just multiple worlds idea. He was a bit like Socrates of his day.
One thing about these exoplanet findings that troubled me was that they all seem to focus on 1 planet. Granted, I know nothing about the calculations involved or the detection methods. I'm a civil engineer ffs and way out of my lane. It's good to know that the experts are considering multiple planet systems.
Loving the Harry Potter T-shirt.
