This is probably the best space content on RUclips. You are a gifted educator and I thank you for providing this content. Your How Far Is It series (and all of them really) are my favorite videos on RUclips.
This indie-documentary is one of the best documentary about cosmos PERIOD. That says a lot since i have seen more than i can count. But after this iam sure able to count or measure it hehe. A perfect serie of knowledge for an amateur hobby-astronomer from Sweden. Thank alot for sharing your wisdom to us in the younger generation, good sir!
RUclips award should be given to D.Butler!! I have been following many channels in this field so far best ever, can’t get better than this, vast knowledge of space amazing skill and unconditional love for teaching. We should appreciate it.
Anyone with even the slightest interest in the Sun, Comets, or Astronomy and what science has been and is doing should look at this wonderful video from David Butler. His video series are about the best on these topics that I have seen on RUclips. As the Sun barrels through space taking all it’s planets and comets with it, us included, most of us live our daily lives oblivious to what is going on. David’s helpful illustrations will make it clear. Just wonderful.
I listen to him going to sleep, in my headphones while working.......Halley’s Comet, I was 6 years old and my daddy rolled up a Bass Pro Shop magazine and we went outback where there was no light pollution and he showed Her. Told me my children will see it the next time it orbited. That sparked my love, my refuge and my sanctuary in the cosmos. I cant imagine what my life wud have been like had I never learned about space at such a young age. My 3 children love it and when my daughters was little girls they could name all planets and tell you facts about space. I love it. This man is amazing. Awesome voice too.
Please don't take this as an insult, but your videos are a wonderful sleep aid. I've made a playlist of them and run them through the night with my screen off. I sleep very soundly and when I wake up in the morning I feel a little more intelligent every day...I'm guessing a lot of it sinks in! 😁 Anyways, thanks for your work. Oh, by the way, I do watch them when I'm awake, too. Astronomy and science are my favourite topics.
Thank you so much for all your work Sir. It was awesome watching this over a cup of coffee before work today, I'll carry the perspective throughout the entire day now. Have a wonderful day.
@@wadesharp11 I'm not sure about that, in Brazil it wasn't visible, if I remember correctly. I was expecting much more, since in the early 2nd millennium people got so scared it must have been really really big and bright
I really appreciate these videos; they really help me understand what a spec of dust on a spec of dust on a spec of dust on a spec of dust on a neutron we are in the universe! Keep up the great work; I love the classical music you play in the background of all your videos!
Omg how have I only just found this channel. The way you articulate is bloody amazing. Thankyou so much for your work. Can’t wait to catch up with all your vids.
I love astronomy . unfortunately in the state I'm in I can't study this, but this channel gives me a great gasp of what the universe is , and I thank you for this david. You're one of my top subscribtions . i don't regret finding you channel from the great video you made over Andromeda
To people that are well versed in this subject, it might seem slow-paced and somewhat juvenile. Some of the illustrations may also appear a bit unclear if not misleading, and the narration a droll monotone. Just guessing. But for beginners, it is well done mostly, and worth seeing. I admire anyone who does their best to disseminate interesting information such as this, especially about the fascinating space program!
I love watching your videos. There are far too many junk videos on RUclips pretending to be educational videos, but your videos are the real deal. RUclips needs more people like you.
Excellent video and narrating. I was only planning to watched a few minutes, but ended up sitting through the whole video. Great quality video in every way.
No matter how many of these types of videos I watch and no matter how articulately, or simplistically it is explained, I still cannot get a clear handle on the size of the Universe. Just when I think I've almost got my head around it, I'm like nope, that's just a few parsecs away.. I truly appreciate the time and effort that goes into making and explaining this subject matter, but I've realised trying to grasp the size of the Universe and truly make sense of it in my head is futile.. Fantastic video, thank you.
So true! I will never become tired of the wealth of knowledge the universe has to provide. It is too amazing to let go. The fact that some people couldn't be bothered by this knowledge really boggles my mind. How can someone NOT be fascinated with this????
Fantastic. What grade do you teach. I'd also like to know more about how you use the videos as part of the classroom work. The howfarawayisit.com website is made for teachers. Any ideas for improvement would be much appreciated. You can reach me through that website's contact page if you like. Thanks.
Takes 40 years to leave the solar system (crossing the bow shock of the helioshpere) and even then, it will be another 40,000 years before it reaches the closest star (if it were going in the correct direction) That's 4x the entire duration of semi-recorded human history or 10x the age of the pyramids at giza. In other words, space is big and empty :'( and amazing!
Thank You for sharing factual information. It is too bad close minded people will never understand the wonders of our Universe. I love learning how the Universe works. Knowledge is POWER!
Since I was small, I saw David vidoes and also Sagan Series, and Jacques custeau series , ... All of them, great reserchers. David have a calm voice, and teach astronomy majestically. You are our best astronomy teacher David XD
And here in 2021, we are still hearing from both Voyager 1 and 2! 43+ years old and still going strong. Humans can do anything if we put our minds to cooperation and success!
Thank You David for all that you do . I had very little interest in looking up until i discovered your Video's . Since their discovery i have purchased my first Telescope and use it whenever possible . It opened a whole new beautiful world to me . So I will continue to look up and to keep imagining this wonderful place called the Universe thanks to you .
This video really made me appreciate and realise my life that how delicate and lucky our existence is in the corner of this tremendous erratic universe. oh my god, i really love my life and really wanna thank the mother universe for letting to have life experience. And THANK YOU soo much for the video.
*Your narration rocks. The information you present is the best. Plus you always provide very interesting information. It's like taking a course on Astrophysics and Astronomy. Your videos are worth watching.*
No matter how many times I watch these programmes about the cosmos I'm never not in total awe at the sheer scale of our universe. This particular video illustrated just our own back yard in astronomical terms, and yet when the narrator says that the voyager travelling at approximately 36,000 miles per hour and that is very very fast in terms of our own velocity capacity, will take 1,200 years just to reach the oort cloud! Just think voyager 1 everyday is another 1 million miles from earth, the distances are simply just beyond human contemplation. I'm going out on a limb here but I strongly believe we will never ever ever have the technology to travel to these long far out destinations for eternity. We will visit other planets way off in the future for certain, but a time will come when the human race will come to realise the maximum of our capabilities in terms of our biological strengths and our intelligence.
We could build generational spacecraft, have a breakthrough in cryogenics, or merge with tech (cyborgs). Otherwise our fleshy bodies will never see another star system in person.
Beautiful work, sir. Truly. Amazing images, graphics, narration - superb. And looking through the comments, I see you take the time to answer questions that people ask. That is a rare attribute on RUclips.
I never used to subscribe to a channel. But next to NASA and Hubble this is the 3rd subscription I just subscribed. Well worth to watch this guy and these vids full of amazing information you barely get anywhere else compressed in short videos. Thank you!
David I have to say this is wonderfully put together. I follow a lot of these type of videos and RUclips and Discovery channel and have to say your voice over is perfect for it (as well as your research). The graphics are spot on and it is a relief to see or should I say hear the background music (which is great) is just the right level to not drown out your commentary.I too watched Halley's comet back in 1986, I will be 87 when it comes back around again and hope to still be also still around to witness its splendour as well as to be able to say I saw it twice in my lifetime.I have subscribed and look forward to watching more content from your, keep up the good work sir!
David, Just wanted to let you know how much I enjoy your efforts regarding your very well presented information, but also how you present it in such a complete fashion. I've been one whom has tremendously enjoyed astronomy as a hobby since I was a child - I am now enjoying my 50th loop around the sun. Much thanks for sharing your experience and knowledge with us. - Jeff in Vancouver Canada
Amazing video. I find astronomy incredibly mindboggling to understand but I love every bit of it. Just here trying to learn new things, and this vid has plenty of it, at least for me. Well laid out too. Thank you so much.
They are powered by RTG's ( Radioisotope Thermoelectric Generators) using Plutonium 238 which was produced in early test reactors and is now in such short supply that deep space missions are severely limited. These very small amounts of radioactive materials produce significant amounts of heat for many, many years making these deep space missions possible. No longer being produced, this is one of the motivations for developing breeder reactors to not only make better use of limited uranium supplies, but this Plutonium 238 needed for space exploration....
Thanks, David Butler! The pandemic had given me the opportunity to go through your videos on How Far Away Is It. Haven't done this much math since Stuyvesant High School (class of 1970).
You are a modern day Tycho Brahe or Johannes Kepler. Using mathematics like it was the air you breathe you have given me a picture of the Universe (as well as the Microverse - can I copyright that, BAC? ) that I am certain is as close to the one you have and by extension the best one there is. As I believe you are the foremost communicator of this knowledge on our planet I just want to thank you. I hope you continue to make these videos - and I have seen as many as I can, many times - until it is time to pass the Torch to whoever is able to carry it. I'm pretty sure you know how important you are but its always nice to know how you affect others. And I am no dummy, going to University still at 60, aiming for a Doctorate in Music. Now that's the biggest number I have ever come across. Six O. Do they keep getting bigger?
I love this series. However, I nearly jumped out of my skin at 13:28 - that glass shattering sound effect was so unexpected in such a relaxing video, I thought someone had broken into my house. Certainly made me pay attention.
Not sure how I arrived at this RUclips video? With that said, I watched the entire thing and my mind is now blown! I can't wrap my head around some of these distances or the number of years it takes for a comet to travel. I'm also not sure why all of this information is relevant or needed? We are so so so small in relationship - we just don't make a difference.
@@virgilmccabe2828 I really agree with you but also feel we are so small in the scope of things that we really don't matter. On the scale of infinity, the earth is smaller than an isotope..
U have to have the divine view, otherwise, it seems like we're just miniscule fleas riding on a humongous elephant for only a brief period of time!! U know what is the lifespan of a flea??!!
Fantastic video! Everything is very clearly explained, awesome visualisations. The historical elements are very useful to put things in a time-depth perspective, which helps to conceptualise the great distances we are dealing with, as do the continuously indicated spatial distances in the video. The video is a perfect mix between real images of objects and events in space and schematic materials and models. The pace of the video is not too fast, which makes it easy to follow and enjoy for a non-astronomer like me. The sound quality is great, too.
I especially appreciate the pace and the sane dialogue as a wonderful contrast to the current trend of videos where they edit out the speakers' inhalations so that there is no break in between sentences or paragraphs. These videos are SO cool! :)
Thank you, I struggle with the maths, but your explanations help a great deal. The distances involved are incredible, there will need to be a massive jump in technology to visit even the closest stars. Once again thank you for the efforts you have made in creating and uploading these videos.
What a pleasant way to enjoy my morning; coffee and this video.
of course, Butler's videos are the best
Alfred Cennedy
They eat it up. 😂
Absolutely.. #Divine in universe
Flatearthers are stupid
Mr David Butler u sir have made me more aware of my special interest of our space and beyond like no other teacher !
Had a lousy day but came home to a new David Butler video......... it's getting better, gets things back in perspective.

just a random question... is your playlist randomized, or you hear them always from part 1 to last part? :)
@@warrax111 I have them in their proper sequence...I don't want to learn things in the wrong order 😁
first class quality information, in an excellent format, we cannot underestimate the value of this exposition.
Thank you so much for all your work Sir. It was awesome watching this over a cup of coffee before work today, I'll carry the perspective throughout the entire day now.
Have a wonderful day.
I saw Halley's Comet at the age of 3, if I make it to 78 I'll see it again. That'd be really cool.
Age of 3? It's impossible silly. Besides, the comet made a disappointing showing in 86. I couldn't see. Most people couldn't.
The Gunman....yeah it was pretty poor in 1986 but hopefully you'll live to see it AND have great eyesight then too.
@@ThomasJr i saw it in NZ back then! Was clear as
@@wadesharp11 I'm not sure about that, in Brazil it wasn't visible, if I remember correctly. I was expecting much more, since in the early 2nd millennium people got so scared it must have been really really big and bright
@@ThomasJr i remember it like yesterday. Up the conservatory in Palmerston North, NZ i was 12yrs old. Fully packed..
Perfect. Thank you. No goofy music or animation. Just the facts.
This is, without a doubt, one of the very best explanations both in visual aid and verbal delivery on youtube, regarding the subjects detailed. Bravo.
Thats for the reminder... science and space are breathetaking
The first minute and 25 seconds provides the most insightful overview of the primary components of the Heliosphere. Well done!!!!
I really appreciate these videos; they really help me understand what a spec of dust on a spec of dust on a spec of dust on a spec of dust on a neutron we are in the universe! Keep up the great work; I love the classical music you play in the background of all your videos!

Just wanted to mention that as of the 11th of December Voyager 2 has left the Heliosheath and is now in interstellar space
Takes 40 years to leave the solar system (crossing the bow shock of the helioshpere) and even then, it will be another 40,000 years before it reaches the closest star (if it were going in the correct direction)
That's 4x the entire duration of semi-recorded human history or 10x the age of the pyramids at giza. In other words, space is big and empty :'( and amazing!

David: You are too much awesome in one person! :) Thank you!
I am so grateful I found your channel..Thank you for sharing your passion with the world.
Your videos are unbelievably good. As good as it gets on this subject. RUclips, TV, any and all platforms. Only wish I'd found your channel sooner.

Such a soothing voice
The video is so beautiful, and required for my understanding. Thank you for doing this, sincerely.
excellent publication sir............very easy to follow and understand for an interstellar novice like myself. Please keep up the good work.
Thank You for all your videos. They are all so informative and clearly explained. I''m from Toronto!

Fantastic production again Mr. Butler!
Thanks David for the new Video. its like Christmas to me can't wait to get home and watch.

Thank you David. The video was awesome.

excellent presentation. love the scaling and giving isolated data context.
I just love his speaking voice
you sir, are an excellent narrator & teacher
Best graphics on astronomy I’ve seen since I went to a planetarium as a kid ! Great video!
This is way better than Science or Discovery channel shows. Better explanations and animation.
I love this series. However, I nearly jumped out of my skin at 13:28 - that glass shattering sound effect was so unexpected in such a relaxing video, I thought someone had broken into my house. Certainly made me pay attention.
So relaxing! Thank you.
Thanks so much for this, the visuals put it all in perspective!

Thank you so much for this! This is amazing. You’ve updated the information and image of the sun and the planets.
I have to say this, the best video i saw in long a time.
Great program. I recommend a microphone guard to kill whistles and cheek noise.
i never noticed those noises until i read this comment. now i can't really pay attention! so thanks a million!!!
Best pace and delivery for comprehending and digesting this amazing knowledge ..Thank you..
Your voice is so calming, very much like Carl Sagan's.
Strange, his voice reminded me of a different - not as wholesome a person's voice as Carl Sagan's.
you are the greatest mr Butler . thank you for the precise information
and most educative presentation you provide us with.
Fantastic video! Everything is very clearly explained, awesome visualisations. The historical elements are very useful to put things in a time-depth perspective, which helps to conceptualise the great distances we are dealing with, as do the continuously indicated spatial distances in the video.

Amazing show, thank you David.
Absolutely fantastic thank you
I love these videos. Now he goes and mixes in the theme from my all time favourite movie. It just gets better
Oh where's the music from?
Thank you, I struggle with the maths, but your explanations help a great deal. The distances involved are incredible, there will need to be a massive jump in technology to visit even the closest stars. Once again thank you for the efforts you have made in creating and uploading these videos.
Super interesting and nice explained, good work sir
No ads, just the way we like it 👍💋
Sir, this is excellent work. I wish you were my physics teacher. Thank you.
So glad to have your channel by far the most detailed and best info out here to learn from.thanks
I didn't want the video to end! Great job!
