In this segment of our “How far away is it” video book, we cover Supernovae and star clusters.
As we start Supernovae, we compare the magnitude of the exploding star that created the Helix Planetary Nebula with the explosion that created the Crab Nebula. We take the opportunity to describe the size and densities of White Dwarfs as compared to Neutron Stars. We also take a look at what the daytime sky might look like if Betelgeuse were to supernova.
We then cover the Neutron Star that that a star supernova leaves behind. We take a deep look at the Crab Nebula’ Neutron star. We then take a look at the beautiful Veil Nebula and the Cygnus Loop.
We then explain what a Type 1a Supernova is and how it works as a critically important standard candle. We show a binary star system with matter flowing through the L1 Lagrange point, and mention Subrahmanyan Chandrasekhar’s solution to Einstein’s equations. We then take a look at the amazing remnants of past supernova explosions scattered across our galaxy including: SN 1006, RCW 86, Tycho Supernova SN 1572, Cassiopeia A with its Light Echoes, RCW 103 with its Magnetar, Kepler's supernova SN 1604, N 63A, and Supernova 1987A. For RCW 103, we illustrate the impact on the Earth if it were Capella that went supernova. We conclude this section on SN with a look at how we find them with transient facilities like the Zwicky Transient Facility at the Palomar Observatory.
We continue on to Star Clusters by pointing out that there are two primary kinds of star clusters: open cluster and globular cluster. We visit some very beautiful open clusters including: the Pleiades, the Jewel Box (NGC 4755), Pismis 24 in NGC 6357, Terzan 5, NGC 6791, and the Quintuplet and Arches clusters. And then we visit some spectacular globular clusters including: 47 Tucanae, Omega Centauri, Terzan 5, M30 and M53.
We conclude by adding brightest globular clusters and Type 1a Supernova as key standard candle rungs on our distance ladder.

I listen every night till I fall asleep,that voice is better than any sleeping tablet....then I will watch again the next day and watch it properly because this series is the best I have come across so far “anywhere”....THANK YOU !!!
andy wakeupworld I do the same. I already watched every video aroun like 10 times, still learning something each time.
Same Lmaooo

his cadence is a part of this effect -- soooooo awesome!

Finally a space channel that gives space the respect it deserves! It took so long for me to find this damn channel, sifting through all the “space documentaries“ that feel the need to spice things up with English accents, cgi and loud music with bass drops of all things! Thank you so much for this channel!
I agreed Mr Butlers channel is excellent. However, there are seldom genuinely made science documentaries with "English Accents" that utlize electric guitars, thundering war drums, and the general rock and roll feel of the type made, lets say, elsewhere. The English accent science documentaries of today are gennerally, slick, understated and beautifully filmed. See David Attenborough, Brian Cox, Jim Al Kalili, Alice Roberts etc. All covering science, without the need for the electric guitar or rock music. Bass drops? Wtf you on about? Enjoy. Cock.
@@Jobby1975 am I reading this comment right? It looks like we’re in agreement and then sort of wanders off into a gray area and then ends with outright hostility? I’m gonna need an English professor or maybe a psychiatrist to help me properly assess this comment.
Best astronomy videos on CZcams!!
Just fabulous. I absolutely love your lectures. So much crap these days with CGI masking a complete lack of substance. Please continue making these wonderful shows for posterity, as well as for your current audience!
Francisco Rodriguez-Letters yes ! Well said ! 👍
Mr Butler, you are a treasure to all those of us who seek to expand our knowledge of the cosmos. All blessings to you for sharing your scholarship with your fellows so freely.
Hi Dave. Nice work. Enjoy your videos. I remember fondly also our working together back on Jefferson in '86.
Steve, You are the first Teradatan to comment on my videos. Thanks. I loved those good old days starting up the first massively parallel OS/database on the market. It was exciting. Now I find that what the Hubble Space Telescope has found is very exciting.
Omg that was 33 years ago 😎
Its easy to say a star is 2 1/2 million light years away but to take light that long to reach us is both all inspiring & mind blowing to even comprehend those vast distances.. In both time & space
About Tycho Brahe's observation... he called it "Stella Nova" - hence the word "nova" which survived into modern science. (Not important, but I am Danish, so......)
About this channel.... so refreshing not to be talked to as a child or a total ignorant - so popular in modern documentaries. No techno music and the words "totally awesome, dude" and no stupid comparisons "distance to the moon - you would have to stack x amount of schoolbusses on top of each other". I like to be talked to as if I was an intelligent person - even though I only understand part of the segment.... ;o)))
It's really hard to get your head around the fact that even travelling at the speed of light which is 186,000 miles per second it would still take you 400 years to get to the star beetlejuice.
Wonder how long it would take on a mo ped.😂
@@mushy295 Depends on what fuel you be using. Hi Grade or normal two stroke.?
The scale of the cosmos is almost unfathomable.
Wonderful job, Mr. Butler, absolutely remarkable! I'm not a scientist indeed, my education is pretty average and math has always been my "black beast" but I do love the way astronomy makes me dream and your documentaries are really the best of the best in "divulgation for simple minds", hands down! Thank you 300.000 times per second! :-D
Maybe 75% of what I learned about astronomy (which is not much) I learned it from this channel. Mr. Butler makes me feel like I am in a classroom. The only difference is: no test, and tuition & fees! (although the videos are bona fide "textbooks").
Thank you very much, Sir.
- Aimé
Educated genius sir ,plus some beautiful oration
Thank you, Mr. Butler. I'm happy to see someone pursuing their passion after such a long hiatus. We love your work. Can't get enough.
What a beautiful video David, must have been a lot of work to create. Thanks sir.
You sir, are incredible. Thank you!
You haven’t made a video in a while, hope all is well. Really enjoy your work, thank you for all the hard work you put into your videos :)
how does this channel not already have a million subscribers?
Fantastic. This whole series is so well written and presented thanks
I fall asleep listening to this voice. So calm and relaxing...
At 20 Million miles per hour, every hour of every day, over a period of one thousand years, the total distance covered by SN 1006 is mind numbing and that with no pit stops or potty breaks. All that distance is just a tiny drop in the expanding bucket of the Universe. Our experience of the size of the Universe, if we could experience the whole of it, would outright kill us.
How beautiful and captivating it is, the Universe is the most hostile and anti life environment ever known......It seems some scientists are donning their rose tinted glasses , with their continued statements ,"There must be countless Earthlike planets" ....while Earth probably is a very rare oasis in this vast universe.....some scientists would state "It's a miracle that we're here at all".....While with the billions of galaxies , even the most chronic sceptic would admit that surely there must be earthlike planets in some "Goldie Locks"zone....Fact is that we most likely will never know, certainly not "life" in other galaxies,...and better take good care of this only known oasis we're priviliged to have evolved on.....
Mr. Butler thank you for sharing your amazing work with the world. Your content and the way you present it is exceptional and world-class. You are eloquent, knowledgeable and inspirational. Kudos to you sir.
Thank you so much for these Mr. Butler!
Thanks for the content
I could listen to this all day. You should read audiobooks.

You taught so many people so many invaluable things that so many others could have done but didn't. The way you've explained how we're able to tell the distance of objects just blew my mind and blew so many of my friend's minds that were skeptics and always said how would they know what it's made of and how far away it is and now they know because of you. Regardless of how many subs or like you may get what you deserve a trillion, but regardless of that just know you've helped thousands of people. Thanks again
Thanks Cory.
Great work you have given me a internal map of our surroundings in our galaxy and universe
mind blowing in 4K ! thank you so much for your work, I am so looking forward to the launch of the James Webb space telescope to look deeper and with more clarity than we can imagine, exciting times indeed.
Fantastic stuff, thank you
Beautiful, especially with the use of Rhapsody On A Theme Of Paganini
Can you imagine what it's like living in Omega Centauri? So much light anything existing there wouldn't be able to see the observable universe.
Thank you for sharing your awesome work.
The best narrator and most informative series ever!!!
Incredible that light being so so fast is actually quite slow in the size of the big picture and grand scheme of things.
Let me echo the praise I see in these comments. This series of videos provide accessible explanations of complicated concepts, with excellent graphics supporting a non-sensational narrative. I first became interested in astronomy over 50 years ago, aged 9 or thereabouts, when Pluto was still a full planet and Bode's Law still got the occasional mention. It's fascinating to see how much we've learned since those days. Keep up the excellent work!
Thanks for the videos!
At 5:44 if I interpret the video correctly I see some of the stars moving also, amazing. Your videos are more interesting and educational than "proffesional" ones.
Thank you good sir!
Soothing, enlightening … brilliant stuff.
Beautiful
😍😍😍
Brilliant, brilliant work.
I mean that.
I just found your channel… wow! I love it! 👏
Could listen to your voice all day long 👌
What a way for a supernovae to end...with a bang!
Thanks for the awesome video.
Your videos are great. The one describing quantum chromodynamics is very insightful. Keep us posted on any more details found. Is there any information on the temperature inside neutrons and protons? Seems to me it is a very violent place.
incredible information
Thanks very much, your a very great astrology teacher. This is fun learning, also the most amazing spectacular images. Very well put together vid! 😁
i agree, fabulous voice while i day dream about the universe.... this sort of lecture should be compulsory to every 11-16 year old, imagine the talent we could nurture if this was done.
Thank u Mr Butler;ur outstanding
Thanks!
"Lecture", just isn't the correct word. It sounds so stern and authoritarian. These presentations are illuminating and inspirational.
Words Fail!
The Blue stars are so sweet :)
on my 2nd watch thru.love the background music at the perfect level and David's soothing voice guiding us thru these amazing videos pack full of interesting facts.thanks for this series :)
Master of the Cosmos Mr. David Butler is.
It is amazing how rich the content is.
¡ Fantastic !
F
Thank you this videos are awesome
You are an amazing teacher. I am learning much here. The Universe is endless, so to speak, but I believe this is not the only Universe. The construct of God is unlimited. I pray we can understand just a bit before we perish..
I have been watching Francis Pryor's Britain AD along with David Butler's How Far Away Is It. The time scales are vastly different, but both explore the unknown past and try to reach a rational understanding.
Considering my place in the scheme of time, I have come to the conclusion that it don't make a damn that I burnt the toast at breakfast.
Dera Dr Butler....The only I can say...is ---Muito Obrigado---- (Thanks in Brazilian Portuguese) and ---Tack saa hemskt mycket---- ( the same in swedish), both my languages.
Little world, enormous universe. Thanks for showing us how small we are....yet so big, if we want.
Very intresting
David, at 22:00 min, do you have any info on the small opaque gas/dust cloud (dark nebula) in the upper left hand quadrant of the Trumpler star field picture?
Thank you for your time and effort!
I love your videos!
I was wondering, what did you mean by "the western sky" when talking about Kepler's supernova?
So much satisfying
Muy interesante 1-10-2018
Whats with astronomy and spoons...
I wish our Sun would go supernova sometimes...
I remember when i used to naively think what we saw at night were mostly galaxies. But the beautifully cosmic sight on a clear night in the country back in 70's
But we only see a tiny bubble of a % of nearby stars within a galaxy of TRILLIONS!!
Pliz continue more of ur lectures
Nice boat
23:06 this just blew my mind. I had no idea this was possible. By that calculation, our solar system would contain 20,000 stars. Unreal.
21:15 I wonder how far those two stars are from each other? according to visual it's less then their radius
These videos are amazing and to get them for free is priceless. Now WHAT IS THAT AT 20:01... looks like an alien ship, please clarify someone!!!
What is a point charge and what dpes it mean that an electron is a point particle?
Is the rate of core collapse for red supergiants a predominantly constant and linear process, or does the rate of collapse (post initiation) decelerate gravitational mass compression due to the inverse-square law?
Still enjoy the "older" videos w/ MUSIC. Sure this isn't PISMIS 24? instead of PRIMIS 24? I tried to look it up. Thanks
Now I know kinda where I am. I do appreciate the magnitude. Thank you.
If the milky way🌌 was made like a supernova, what would be the weight and size of the stare to creat it? Thank you.
1:51 I believe I have read a more recent estimation of Betelgeuse's distance of about 700 lightyears?
This video makes me jealous, if the human race makes it through the next 1000 years surly after that they will explore these places, wish I could have been there to explore this awesome universe, I guess I will be somehow through the human spirit
Maybe if you think the human race will ever explore these places, you haven't really understood "how far away it is".
It is a good point, it's unimaginable how large it is.
How do nebulous form stars? If they're only the remnants of one star how do many stars form from them? There's only the material of one star extremely sparsely spread out.
I wonder if Super Massive Black Holes are formed from a Globular Cluster of stars all crashing together in the middle at the same time.
what would we see if habour fly to outside of solar system？
To David Butler from James U. Which reality are you from? Because in the internet of my world on Earth, the stars and sun are different and you don't exist here. Please let me know asap. Thank You.
And Bach playing in the background...OVE IT...but I still have a problems with distance...
WR stands for "Wolf-Rayet", right? Isn't R-136A1 in the Large Magellanic Cloud a Wolf-Rayet star?
Yes it is.
When our Sun explodes I'm hoping to be in Proxima Centauri 😂
If something that big collapses that fast I could see how there would be some reaction
Question Cosmic recycling. If a star dies after using up all its hydrogen and explodes. How does a new star form without hydrogen gas?? Sorry if it’s a stupid question.
So far, only a small fraction of the Universe's hydrogen has been used to form stars. There's plenty left for current and future generations.
David Butler thank you
how far away is it ?
9:00 - 10:30 - I wish we'd get to see one in our lifetime, or in mine in the next 40-odd!?-ish maybe yrs!!
10:11 - Come again, the shockwave would be tearing us apart right now! Please elaborate to this point.
Like literally, like a melon as the Earth with an M-80 Airbomb detonated inside it!?
Or like an orange with its skin peeled off!
or shotgun peppered when the contents of the Kuiper belt and Oort cloud are shot towards us!?
or just deadly lashings of immense heat and gamma radiations!?*
*this is how Planet Hulk 2 comes about! Population: Red Hulks! :D
Also, what of the Sun and other planets of the solar system
Uneducated comments based on movies. 🤨
I Wonder if you were on a planet in the thick star cluster the daytime sky would look like with each stare only being a third of a light year away from each other...
Is there a music-free version available?

@@howfarawayisit Thank you!
pampaantok hihi
If the Milky way is 40k light years across how can galaxies few hundred light year be closer than our own galaxy across ?
In one of your other video's Betelgeuse is over 700 light years away and in this video 427 light years...🤔🤔
I too observed that
@@jinkhazama9168 It may have been away on vacation.
David, have you quieted the background music because kids "don't like classical music"? I am messing with my speakers but I can barely hear it and was one of best parts of your original series?
I have reduced the music volume. Most comments on the music complained about not hearing the words. Sorry.
@@howfarawayisit the content is so fascinating, that it would be a pity to miss it for being distracted by the music!
I really really wish there was no background music
Why not click one of the links to the music free version?
Everything is spoken matter of factly, but are they truly?
The andromeda, when your there could hide itself as the milky way galaxy? We could be there could'nt we. Aliens stole earth once. Good supernova
