Just the carpenter here but thanks for teaching me something new I like to see somebody passionate about geophysics as awkward as it might be for you I appreciate it
Very interesting lecture and a good passionate speaker! Lessons for the future: Keep the slides on screen always and maybe a small window of the speaker in a corner. When the speaker points to something, show the slide using the camera so that we can see the laser-pointer instead of using the slide directly from file.
Fascinating, especially after all of the nitrogen-centric geology that everyone went nuts over on Pluto (Sputnik Planitia I think it was), I had no idea that Charon's geology was so water-based. I'm curious about the big polar crater. Rich Binzel's CfA lecture made a big deal about it (it's roughly equivalent to Mercury's big crater, for example) but it wasn't a factor here. I find myself intrigued.
This has to be one of the best Science talk's ever! The fact that he said, we think, we don't really know, we guess! This is exactly what I would expect from an educated person... It's okay to not know something! That only reaffirms the need for more investigation in certain areas rather than get comfortable with a theory till people start using it as a fact! Which goes on way to much these days.
big love for the greatful people in this tube. it gives me a hopeful view in to the future, when someday the mankind works peaceful together nice greatings from germany. thank you.
The flow areas that look like puckers remind me of watching in slow motion liqufaction during an earthquake! The water and mud is forced up through cracks and then flows out over the flat surface and then drains back into the cracks to repeat the process while the quake happens leaving the more solid muds or sands behind on the surface, but when the quake ends you are left with this type of looking terrain around the cracks caused by the quake and the deposits left on the surface by the now dried muds. I wonder if that is the type of process going on here on Charon, but much slower because it is colder and is not solely due to water ice, but includes other types of ices, which when warmed by tidal forces causing internal heating, and which are then forced up through the water ice by tidal flexing and deposited onto the surface, just like the muds during liquifaction! This is also similar to the "tiger stripes" we see on Enceladus, but much less forceful, because of less tidal heating and a colder spot in the solar system farther from the sun. Slow motion plumes or burbles of melted methane and nitrogen ices being squeezed out of cracked water ice which is as hard are granite on Earth are, when at temperatures common to Pluto and Charon.
Or...... The so called mountain is a separate object that impacted Charon...its even a different color. The moat was an old depression probably from a larger prion impact causing the remaining "moat to be not quite circular due to at least 2 impacts at that site & due to the fact that the impacting object was not completely round.
Look. We have all seen the grade school version of the facts. Those of us who keep up on this are hoping like hell that eventually some actual grown up versions might be added someday.
It blows my mind how uneducated some of these commentators are. Maybe some are high school students, but I knew about orbits and basic physical mechanics and geology, and chemistry etc when I took classes in high school! The dumbing down of kids in the US is really sad. Your lecture was amazing regardless! On a side note, I kind of lost where the equator is on Charon relative to it's co-tidally locked partner. Is it where we see the line where the smooth and the rough meet?
If you want to watch a professional public speaker I'm sure there are videos of Newt Gingrich or Hillary Clinton on UA-cam for you. I personally prefer to listening to scientists, even if their speaking skills aren't that great.
Just found it after the „Shooting“ at Fox.... A Great example of that kind of the US we all Love in the world...the cool dude who scientific explores the outer rim! Nice to hear from a German perspective you still have really „Angst“ over there, back Home we stay away from the guns ☝🏻... learned the lesson 😉... everything is fine...no more fear ...ease! Fear leads to anger...anger to hate...hate leads to the dark side😉 Best wishes to our American friends: get back to your Core...cool a little bit down...and rise slowly with dignity, step by step. The marks will seen till rest of time 😎
Charon's a planet. The point of mutual orbit is in space between it and Pluto. There's the seed for your funding, a whole new planet that no-ones ever orbited. Great lecture, thanks.
@Jari. Try balancing a marble on top of a bowling ball. Or better still imagine it. Anything that drifted into that null point would still have some speed in some direction. So things could . . pause . . there for a while, but when the next thing drifted in and gave them a bump they'd fall one way or the other. Keep in mind that gravity between small objects is VERY weak.
Not a planet : perhaps a Dwarf planet, part of a binary system of dwarf planets Pluto-Charon. But the IAU doesn't give a clear definition of what is a moon and it doesn't list it as a dwarf planet either. So the issue is still undicided really.
@CyrilleParis. The astronomer Patrick Moore proposed the definitional boundary I used in my post. It's the only one that makes any logical sense. I suppose I can live with them being classified as dwarf planets.
@@sciencetroll6304 Should this mean that stuff would gather on both Pluto and Charon as a mound not as large as a moutain but a higher elevetion this on the sides that face eachother - woulnd this also mean the gravity is anti G on both facing sides. THis meaning if you jumped with a suit you would end up on Charon from Pluto
One of the first things he does is explain why it's not pronounced with a "k" sound. It has to do with the man who discovered Charon, and his wife's name.
Sorry. I had to give up after 9 minutes. It was just dumbed down too much. I felt like he was talking to an audience of Junior High School students. I would also have expected him to pronounce it correctly.
Very interesting analysis of Charon's geologic and chemical history, but this guy is a terrible speaker, very condescending, speaking to the audience like we're all 7 year olds and he should not be making any jokes, definitely not his milieu. No offence, if you're reading, I'm sure you're a wonderful geologist, but get to the point and don't assume that everyone else is intellectually challenged.
"the object was named Charon after Pluto's companion Kharon in mythology (but most Americans pronounce the name as "Sharon," in honor of Christy's wish that the name also honor his wife, Charlene)." www.spaceref.com/news/viewsr.html?pid=17180
In the 1970s I learned it was a planet. The Kuiper Belt and the Scattered Disc were still unknown in 1930 so yes, what else are you going to call an object in orbit around the sun. But it was a STRANGE little planet with a strange orbit, in a 2:3 orbital resonance with Neptune… and when Charon was discovered it became known exaxctly HOW tiny it was. So I had no troubles with the 2006 IAU reclassification.
Thank you so much for this presentation, keep them coming! :)
Excellent lecture. Thanks for posting. Great to be able to attend, if only virtually.
@BLAIR M Schirmer better then nothing isn't it?

It should be known to them by now, this lecture series started years ago.
I 2nd this.
Yeah but skip to like 18:00 if you already know the basics about the orbits... and 22:45 he shows a really dope picture.
Privileged to be present during the lecture! Highly informative!!!
a trick : you can watch series at Flixzone. Me and my gf have been using them for watching loads of movies these days.
@Reece Orlando Definitely, have been using flixzone for years myself :D
If you liked this you may also enjoy Isaac Arthur's newest video about colonizing Pluto and Charon.
Passion can sometimes be confused with caffeine
Thank you so much for sharing this with the world. 😄😄
Thank you for teaching me something new xx
This speaker makes it exciting.
Curious what happened to the podcast feed of these lectures? It's unfortunate the feed is no longer updated.
Talk begins 3:00
... or 15:45 to skip a very long and unnecessary telling of how Charon got it's name.
great lecture , i understand so much more about this moon
Good show good theories good speaker
Wonderful lecture!
Yay, very entertaining, thanks.
2:50 that was quick:)
thanks so much, that was a stupendous lecture!
GREAT lecture. So fascinating. Thank you!

Gregory Benford and Backscatter look it up you might enjoy it after this lecture
Excellent lecture.

I'm trying to understand how big the Sun would be if we were standing on Charon?
Go outside while the ISS is passing over. The Sun would be about that bright (but not moving, obviously).
@@cuscof2 really? How can it get any light off of it then.
Charon even looks burnt. Pronounce it the best way: Char(like charcoal)-on
Ancient Greek has "ch" as a hard "k", so "Ka ron". Google it!
@@dunruden9720 Yeah, the pronunciation thing was driving me crazy (which is, admittedly, not a very long trip). Thanks Jim in 1978 😝
Yeah but a lot of astronomers and NASA prefer the "sh" pronunciation because the discoverer wanted to honor his wife Charlene.
good explanation
I love the spooky intro music.
FrrrrrrrrrrrrrrrrrrrRRRRRRRRRRRRAKKKKKKKKKKKKKKKKKKKKNOI!!!!!!
I wonder if he's a Battlestar Galactica fan.

I enjoyed this talk but have to ask, does Dr. Beyer always lecture in his PJ's?
We should frac it ,and see what oozes out...
3:06 --->

Ok,ok, what do you do for a living again?
JK
Great talk!
"Sharyn?" or "Shazza," as we say here in Australia! Lost me there, oh great master race!
Charon lol , stay safe down under from blighty UK
liked it make more videos

Is it where we see the line where the smooth and the rough meet?
There was a picture with the poles, equator ect. superimposed on it. The fracture zone is a bit closer to one of the poles I thought.
I'm sorry, I got so distracted by Dr Beyer continually saying "right?" that I finally had to turn it off.
If you want to watch a professional public speaker I'm sure there are videos of Newt Gingrich or Hillary Clinton on UA-cam for you. I personally prefer to listening to scientists, even if their speaking skills aren't that great.
Steve Baxtmer Gossamer also
it is NOT a K or a sh sound, it is a CH like in lochness..., come on it is also CHaos in greek and in dutch...with a ch like in lochness...
Just found it after the „Shooting“ at Fox....
A Great example of that kind of the US we all Love in the world...the cool dude who scientific explores the outer rim!

Charon's a planet. The point of mutual orbit is in space between it and Pluto. There's the seed for your funding, a whole new planet that no-ones ever orbited. Great lecture, thanks.
shouldnt the point in the middle gather material ? rocks or gas ?
@Jari. Try balancing a marble on top of a bowling ball. Or better still imagine it. Anything that drifted into that null point would still have some speed in some direction.

should have drawn faces with kissy-lips on all the white dots - everyone get an idea what tidal locking mean then. etc.
fracknoi's my boy - let these guest speakers yap for too long and they just get big-headed and want more scotch off you the next time.
So you believe me
Is he maybe trying a bit too hard to be funny? Stilll very good.
You should see the lecture Michael Brown did about Pluto...
⚡️♏️=🌏⚡️
it's not a k sound yank, it's a CH sound like in loCHness it is CH-aron, with a scottish / dutch/ german / greek ch

He did pronounce it correctly. Perhaps you gave up too soon for the explanation.
CSI-LOL

ummm....no, it is hard K "Karon", you don't get to name things after your wife or cat or neighbor.
The person who earned the right to name the object by discovering it in the first place doesn't need your permission.
"the object was named Charon after Pluto's companion Kharon in mythology (but most Americans pronounce the name as "Sharon," in honor of Christy's wish that the name also honor his wife, Charlene)."

Did you learn Pluto is actually a planet? If not you didn't learn much.
I learned it's actually a dwarf planet
In the 1970s I learned it was a planet. The Kuiper Belt and the Scattered Disc were still unknown in 1930 so yes, what else are you going to call an object in orbit around the sun.

So I had no troubles with the 2006 IAU reclassification.
About 11 minutes in to the lecture and hearing him say "right" for the 7000th time. I had to shut it off.
I’m getting distracted by the constant smacking. Such a shame.
It's all a charade. The earth is flat....
How about Pluto and Charon? also flat?
