Wow! This is the first video of mine to break 1 million views! That's amazing! Thanks for the support! You can watch the entire series of videos here: ruclips.net/p/PLyu4Fovbph6fl0UGSo3aLqHCmBIYkiqzq
Jason, congratulations! Astronomy is such a beautiful, enchanting and indeed grounding subject to study and immerse oneself in. Whilst a lot of accessible online resource is skeletal, your output answers so many questions, some of which I’d yet to ask. Thank you for all you are doing here.
Same. Dont even know how this video came up as I dont put things in auto play. But while waking up, this was playing and then listented to 20 more minutes.
This is wonderful to watch...feels like I'm in school at my favorite class with my best teacher! I recall the 8 year old me being asked what I wanted to be when i grew up ,by my grade 3 teacher "A scientist"...was my reply without hesitation. That never happened, but here I am ,62 years later, just as in awe now as i was then. Thank you so much for giving this old man such an enjoyable viewing experience!
What do you mean "it never happened"? Being a SCIENTIST is about being TRUE, being OPEN, being brutally FACTUAL, and - obviously - being CURIOUS! NOT about getting degrees, writing papers and making academic careers - all that is so so secondary! What is living if not doing RESEARCH? I bet you are smarter and practically more useful and helpful than 99% of the new University Graduates in WHATEVER field : )) Sounded to me like you kept true to the essence of what BEING the scientist IS, and at 70 years old still have the sense of awe and wonder when learning new things about the Universe AND a sense of simple, humble human appreciation to find the few minutes for thanking the author - YOU ARE a SCIENTIST, SIR, pure and simple, let all these diploma-waving ignoramuses know! :))
If you are only using this for sleep, you're going to miss out on the most important galactic information known to mankind. This answers so much of the things I think about, and it does so in a graphic format where I can actually imagine the scales of things I never could before. Thank you for this video, Jason Kendall! Oh, and by the way, this was done in 2018. We have since taken an actual picture of the SMBH in the center of our galaxy, or at least the accretion disk that proves Einstein's theory about black holes.
@@ahmadkoopal3120 Anyone can learn anything. I used to feel the same way as you. I used to think concepts of math and science were too difficult for me. I never even completed HS. I decided to go back to school at 40 and turned my curiosity into a second career as a science teacher.
1.5 million views!!!! I couldn't be happier for you. I've recommended your class in the comment sections of Fraser Cain, Cool Worlds, and Anton to name a few. Hope this brings more viewers your way. I'll keep watching and liking your videos and leaving comments in your section to please the almighty algorithm. Least I can do for now.
Thank you so much for making these wonderful videos! You've renewed my curiosity in the world around me. Your love for science is infectious and you communicate it so well.
I agree totally with you. Professor Kendall is a wonderful teacher and he explains every topic so well. This series is so great and it is totally free. I went to college to get a degree in Astrophysics many years ago but never finished because I lost my student aid. This course is such a great way to catch up on the latest research in this exciting field. Muchas gracias a professor Kendall!
First time hearing your channel I'm obsessed with face and sciences I must say that this is on or above quality of well-known RUclipsrs as Frasier or Anton thank you earned my sub ty again
I don't bother with anything that's less than an hour. So many of these channels have incorrect information. So many of them mislead and people think they're educated when they're actually getting dumber. I love how long this one is. And how informative.
The aliens would firehouse whatever they drink out of their nostrils and roll on the floor screaming with laughter, when they learn we call our galaxy “The Milky Way”.
2:07 Questions about "1) Redshift": 1. All celestial bodies exibiting redshift, and thus moving away (from our perspective), are bodies situated milions/billions of lightyears away. Thus the redshift we see today happened millions/billions of years ago. Thus the observation we make is no longer up-to-date by millions of years. Are we sure they are still redshifting or are they blueshifting bouncing back, but that light has not traveled back reaching us yet? 2. If our perspective is not the center of where celestial objects are redshifting from, moving away from us, is it logical to expect the same redshift movement everywhere? That would be rather a coincidence.
Hey jason, I doubt you will even get to read this because I imagine you are extremely busy but, I've been watching all of your videos over the past few months and I felt compelled to leave ya a comment. Your videos are so I'm depth and I just love gaining all of this knowledge from your videos. My daughter has now begun to watch them she is 12 and she sticks to the iPad like glue watching your vids!! Woo keep it up man your amazing, and thanks again from the Taylor family!!!
That’s great! These videos weren’t made with 12-year-olds in mind. But if she is into them, and really likes talking about them, find all the STEM resources you can and get them to her. School resources won’t be enough. I took college classes proper in 8th grade and was fully enrolled at university before 9th grade. I graduated high school with half a computer science major done. I ended up with an excellent career. I still went to and finished high school, I just had permission from the high school to take classes that were not currently offered. If she is great at math, then have her follow the path of my mother who dropped out of high school to go to college and become the youngest graduate student at Harvard at 19.
Who would have thought 20 years ago watching you play baseball for the Pittaburgh Pirates that you had such knowledge of astronomy. I'll never forget I was at the game when you broke your ankle. Still to this day, I can't get the image out of my mind. That injury was right up there with the hit from L.T. that broke J. Theismanns leg.
Very funny story about that.... I was once contacted by a gushing fan of his. I played along but said "please don't let anyone know about this email" (which was different at the time) "but I want to thank you for your support, and I hope you're able to come watch more Pirates games!" I knew that if I impersonated him, I had to do him quite right, and make sure he got all the praise. Same thing applied when someone mistook me for Michael J. Fox on an airplane once.
I love your sense of humour and the way you explain the equations makes what initially looks like a bunch of letters and numbers around an equals sign very understandable - cheers for the upload and will be working my way through all your long videos at bedtime :)
I remember what the milky way looked like in the early 60's from Maui Hawaii. I lived in a small town by the sea . It was quite beautiful as there were practically no lights at that time. Especially during the new moon phase.
@@JasonKendallAstronomer unless you're out at sea sailing. No lights whatsoever. I haven't been out to sea on a sailboat but I'll bet the view of the milky way is incredible.
No doubt. We used to have a boat on Elephant Butte (southern New Mexico) and the views at night were amazing. Not perfect but it was remote enough to get amazing views.
I've only been a visitor, but I have gotten to see the night sky from the summits of Mauna Kea and Halealala, both views were so dark and clear that it took me more than an hour to re adjust to the constellations, because for the most part, I could barely tell which one I was seeing. There were so many more stars visible, and they appeared so much more uniform in brightness that I struggled to find even the most obvious landmarks otber than the Milky Way.
Thank you for including Pluto as a planet! I too believe that the New Horizons project and images sent back of our beloved 9th planet are the most incredible discoveries of our lifetime!
Great lecture series, I really appreciate it. It's helping me big-time to place individual knowledge into a broader picture, meanwhile I'm getting the occasional revelation, such as the spiral arms of a galaxy not being spirals at all really, but are instead individual blobs of gas and stars in their individual orbits that are currently lining up to show us a spiral as we take a snapshot. The spiral is a lie. I found a fun little blooper at 3:14:40 as G350.1-0.3 was called a "galaxy emitting cluster", hehe.
Thanks for the blooper find. When I get around to remastering this video, I'm sure I'll fix that. And actually, the spiral isn't a "lie", it is what we see if you aggregate the view. That is similar to saying that a cloud in the sky is a lie because it's an aggregate of water droplets. Or a dog is a lie because it's really a collection of diverse cells, most of which are non-dog bacteria.
Not to worry at all! It’s just that you should see the loopy comments that come in. I knew it was all in good fun. I just needed to think about those who might just take it seriously….
The third earl of Ross lived in Ireland. The original structure which supported his scope and the scope tube are preserved at his home place. The mirror is in the science museum in London. The earl made drawings of spiral structures... galaxies may have been the first. ?
With respect to the galaxy formation presentation, it appears observations through JWST found well form galaxies within only 500 million years after Big Bang.
A Flea living on a Dog, no matter how clever it thinks it is, or what it claims to know, will never comprehend or accept the truth that it just lives on a Dog...
3:33:44 I like to repeat these words: A 4 million times the mass of the sun. I think of things. Of heavy things. of VERY heavy things. Of the HEAVIEST things, and I know that this is beyond my imagination, forever. Same with 1:26:51 "hundreds of billions of galaxies in the universe.... " my imagination crushes under the size. What does Dr S Freud say about the milky metaphors of the objects in the universe?
Sorry for my ignorance, but i have a question. In the image at 1:21:29 taken by ESA's Planck, the background shows something like the lines of an electromagnetic field, what is it?
That image specifically shows the microwave light emission due carbon monoxide. It’s a simple molecule that forms easily and is a tracer for hydrogen gas clouds. Here, Planck is trying to map it to remove it from their primary goal of seeing the cosmic microwave background.
the fact the universe could not drink in america blew my mind, thanks for the knowledge !! would love to translate these into french for my folks but i m not sure they would even care to listen 😅
How about the AndroMilkymedaway? Don't think much to the planned combo. Would the large clusters of dust and gas of the milky way ever experience electromagnetic storms or anything caused by collisions or friction the cloudier areas? Some images of the galaxy from side on look as if it's a storm or a massive explosion still in effect.
There are many. Start with contacting nearby universities that offer Astronomy or physics degrees to see if they provide public events. Also search for amateur astronomy associations or clubs.
Thanks for the donation! Just want to let you know that this helps me al lot! I'm busily working on new content, and getting ready for another release!

I heard this term cosmology before, but in a religious context, like Jewish Cosmology, or Hindu Cosmology for example. What the relationship is, if any, I'm still trying to understand.
Cosmology is the study of the entire universe. It used to be the purview of religions, which tried to explain Where It All Came From. But now, we understand so much more. It is now a precision science. Religions still give each their own human-centric interpretation of “Why Was This Made For Me”, and “What Is It All For”? Science seeks to understand the reasons for the natural phenomena that are in abundance. We now have the tools to understand how the universe has changed and grown from the very earliest times. Scientists debate and research the boundary points of knowledge, not resting on or aiming to reinforce one final story, in the manner of a religion. The goal of science is to offer explanations to what’s observed, and see if they fit and if they fruitfully lead to more questions.

Describing galaxy rotation reminds of that 80's song: "You spin me right round baby, like a record baby..." Unfortunately I don't think not of that era would get the rotating record analogy. *shrugs*
3 h 3 min: What if light is dark matter? 23 % sounds like the 23 % Helium we (the Universe) have fused into light and energy (heat) already at the moment. Light does some fast and "bending" stuff to at least itself - why than not to space an matter? In (Galaxy) Centers or Spiral Arms there is plenty "more" light around making things.
1:41:45 "the sun takes 2 1/4 million years to orbit the milky way" Uh no. The sun only makes it 1% of the way around in that time. You have made an error.
I admire and apriciate the plead for change. But then you know.... A calmness settles over you and then suddenly Elon goes supernova implodes back on himself... Only to eventually vapour, radiate into entropy. I'm wish I'd still had fate in mankind overcoming the discrepancy between their theoretical best odds and their practice. Though we are strong when the masses unity and God is dead, we are moving towards more individual, we are confused and may fear the future challenge which causes a vulnerability towards populism, lack of optimal rational change collectively in the right direction... But we are in motion and with increased velocity. The energy needed to / time = the apple on tree - out of reach moving away. Unless AI comes up with a backup plan to save the day. But if I were AI and would try to come up with ways to improve the conditions for earth to host life... Uhhhh ups.
Each stars has their own god/jesus who went down to their Earths to teach inhabitants😂 Jokes aside, can we say that the observable universe is filled with other humans, given that physics applies everywhere else in the universe?
Famous science fiction, notably Star Trek, have a theory of convergent evolution to explain why all of the aliens look human/humanoid. It was a little handwaved because they couldn't make good looking ALIEN aliens back then. You may also be interested in Steven wolfram's computational physics research, where the evidence is pointing to physics being this way because we observe them this way, and if you get far enough away physics may actually work differently. Just some food for thought. Cheers!

There’s a very different light curve profile for a sphere passing in front of a star.

how do you apply all this knowledge????

I saw the milky way move with many shooting stars holy shit like 10 shooting stars
Omg. I can’t. “Cause ya want meat!” lol.
I woke up to this

Pluto ain’t a planet never should have been! New horizons was great though

The merge of the Milky Way and Andromeda isn't "long after the Sun extinguishes". It will happen at about the same time.
Thanks for the catch! I’m in the process of redoing the whole series, so I’m going to need to pick out flubs like these.
Andromeda is closing at c/1000, so it makes for an easy calculation….if you use light years, and not the dreadful parsec.
Lots of new information to cover, a lot of it thanks to jwst. :)
Measurements and metrics
@ 1:10:05 there is a police siren
2:34:00 need this image on a shirt.
3 h 3 min: What if light is dark matter? 23 % sounds like the 23 % Helium we (the Universe) have fused into light and energy (heat) already at the moment.
Light does some fast and "bending" stuff to at least itself - why than not to space an matter?
In (Galaxy) Centers or Spiral Arms there is plenty "more" light around making things.
I feel small.
They know a lot
very well into the delusion I was like you once when I was in school.
Such delusions are good.
🎉🎉🎉
The earth 🌎 isn't flat ,flat earthers brains are just 1 dimensional
I prefer the guy with the English accent!
Forgive me mate🙃
Aw stay on this side on the pond with me!
👍👍👍👍
1:41:45 "the sun takes 2 1/4 million years to orbit the milky way"
Uh no. The sun only makes it 1% of the way around in that time. You have made an error.
Thanks for the catch! It's more like 225 million years, or a quarter of a billion years.
I knew you knew that, its correct later in the same video. Glad to help.
👍
I admire and apriciate the plead for change.
But then you know....
A calmness settles over you and then suddenly Elon goes supernova implodes back on himself... Only to eventually vapour, radiate into entropy.
I'm wish I'd still had fate in mankind overcoming the discrepancy between their theoretical best odds and their practice. Though we are strong when the masses unity and God is dead, we are moving towards more individual, we are confused and may fear the future challenge which causes a vulnerability towards populism, lack of optimal rational change collectively in the right direction... But we are in motion and with increased velocity. The energy needed to / time = the apple on tree - out of reach moving away.
Unless AI comes up with a backup plan to save the day. But if I were AI and would try to come up with ways to improve the conditions for earth to host life...
Uhhhh ups.
Neeeew suuuub
Each stars has their own god/jesus who went down to their Earths to teach inhabitants😂
Jokes aside, can we say that the observable universe is filled with other humans, given that physics applies everywhere else in the universe?
One can always say that, but when dealing with it as a scientist might, one must always gather evidence to support an extraordinary hypothesis.
@@JasonKendallAstronomer Thank you for your reply good sir💯. I understand.
Famous science fiction, notably Star Trek, have a theory of convergent evolution to explain why all of the aliens look human/humanoid.
It was a little handwaved because they couldn't make good looking ALIEN aliens back then.
You may also be interested in Steven wolfram's computational physics research, where the evidence is pointing to physics being this way because we observe them this way, and if you get far enough away physics may actually work differently.
Just some food for thought.
Cheers!
Coolile
Only if the galaxy is male tho.
Lol
