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

Fascinating look at exoplanet history. Thank you.

Excellent chronology of exoplanet discovery history.

Fine work! I'll save this one for future study. Thank you Dr. Smethurst.

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 :).

Excellent summary!! Keep going

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.

@pansepot1490

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.

Fascinating stuff. The variety of exoplanets and the methods of discovery are almost as numerous as the odd names of astronomers and astrophysicists.

Between Bruno and Newton there was a certain Tuscan gentleman called Galileo Galleli who was also suppressed, but mercifully not burnt alive.

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!

Brilliant!!!

Beautiful the way you explain! Greetings from Costa Rica 🇨🇷 🎶🎵 Saludos cordiales!

That was highly enjoyable and informative delivered in your delightfully clear 'down-to-Earth' style. Thanks for that. I bought and read your book, enjoyed it, and look forward to your next lavishly illustrated version. However, I'm a little confused by a paragraph on Page 60 where you state that Voyager 1 would take 74000 years to reach Alpha Centauri but would only take 40000 years to pass close to a star in Ursa Major that is much further away. Is this a lack of common sense on my part or a typo?

​@@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.

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.

Curious, but does the eye of the explosion from a star, specifically the empty space, reveal anything in particular about the properties of the chain reaction of it going nova, based on which sides are pushed out first/faster, or something similar?

Your the best!!!!

Your book is out in the US now; I just ordered it from Amazon.

This is very exciting, I wonder how these results influence the Fermi paradox, for example if we live on a one-in-a-million planet.

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?

Subrahmanyan Chandrasekhar got his Nobel Peace Prize in Physics in 1983 ... 50 years after his discovery of how relativity predicts the collapse of massive stars into a singularity.

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.

The Hubble Space Telescope became instrumental... A lofty goal for an instrument. :)
