Introduction to Astronomy 

I am 14 years old and I want to learn more about astronomy but my school hasn’t that lesson so this is really helpful thank you . .

Thank you so much Professor Dave. I'm a 49 year old maintenance technician and am interested in studying to get a BA in mechanical engineering. I use your physics and math courses from time to time as a way to keep my mind fresh and pass time in an educational way. Recently my 14 year old son has showed an interest in science, particularly astronomy. Long story short, I turned him on to your channel and he is now a well-spring of knowledge. Keep up the good work Dave.

Damnit. This series isn't receiving nearly enough attention. Dave has put together one of the most excellent astronomy series' ever made (I've seen A LOT!) and hardly anybody is watching it. This saddens me deeply. Honestly, Dave's knack for making complex subject matter incredibly easy to grasp & understand... I'd love to see some of his work make it into classrooms. If it were up to me, his entire channel would be required viewing. We'd have a lot fewer "flat-earther" buffoons running around, for one.

Hey I am a 110 year old embedded software developer for satellites. I always wanted to learn astrophysics, this is a good start. Thanks.

This guy thought me relativity and now he is going to teach me something new

He deserves more recognition! He makes everything so easy to understand. You're doing a great job, professor Dave!

sir it seems u r super all rounder .. teaching everything .. physics , maths , biology, chemistry , now astronomy.. great

Why didn't I discover this channel before!!

Dave, just found your channel, and already I feel at home. I've longed for learning all of my life, and I can hardly wait to see what you have to say! Thank you for sharing your knowledge!

I am 25 years old and learning with more stimulus with this playlists. THANKS DAVE.

Finally getting into amateur astronomy and this playlist is everything I needed!🤓 My oh my the universe is fascinating 🤩 Thanks Professor!

Thank you for the videos. After retiring from the military and being a network engineer afterwards … since a child I wanted to become a scientist. Though your videos won’t get me my Doctorate, it has quenched my thirst for the knowledge. It’s amazing how much has changed since the mid 90s.

My five year old grandson and I found you about 6 months ago. You are a fountain of knowledge ! Wesy and I think you are awesome! Thanks Professor Dave

This channel is a gold mine. Thanks Prof Dave.

Best teacher around in RU-vid 😍

Nice One...i was just planning to learn the basics of Astronomy and then your Video Notification pop up at my screen

I'm a 13 year old and I want to know more about astronomy because it's very cool and your videos across this playlist helped me a lot so I came back in the very first video when I find out your channel to say: Thank you so much Dave! Much love from Brazil

I fall asleep listening to this playlist of the universe every night. Its like a bedtime story that is wonderful and magical but better because it's also true and I'll never see the end of this mystical science wonder.

I've been observing things with my telescope and taking photos with my camera for about a year now and love space, now I can learn more about the things I've seen and captured.

Those were the good old days, when you could SEE the stars!! The ceiling of Grand Central Station in NYC is BACKWARDS from the actual sky, I guess because people haven't been able to see stars for over a hundred years in many big cities.

Now I may only be 13 but I have always wanted to be an astrophysicist since a young kid and my school doesn't offer any of this so, Thank you so very much for teaching this.

I am 14 year old and I really love astrophysics but my school can’t provide for it so thank you so much professor for providing us this information🙏🏻

Already love the new series. All the best with this one! Can't wait for the next parts

Here, it's me, I am a 12 year old trying to understand more about Astronomy and astrophysics and black holes, but ofc we don't have anything about it, this has helped, thank you sir

0:03 I got my Cheez-Its ready - let's do this!

Thank you very much. I am a layperson. You are helping me to understand a massively complex yet fascinating subject

Introduction to astronomy? More like "I really can't wait to see"...what this series has in store. Thanks again Professor Dave for every single video that you have made!

Another exciting series can't wait for next videos!! I have told all my friends to watch your astronomy series!!!!

I know it’s not good to share ur age especially if ur under 13 but I’m 10 almost 11, this is so interesting and easy to understand. When it seems like class is too hard I just watch this series after school and it feels like an escape from reality. This is amazing

There ought to be a No Lights Night. I know there's something similar to that but it's only an hour. We need more time to take in the majestic beauty of the universe including the Milky Way.

I dream to become like you one day!!

Enjoyed this video. Made great sense, you hooked things together very well.

Thank God for such kind of hero among us who will teach us science in a very interesting way

Somehow Professor Dave makes everything easy to understand. Thus I must than you professor Dave. For you have accelerated my knowledge in astronomy and astrology! Thank you.

The best Introduction of Astronomy.

I love deep oceans and deep space than anything else .....so thanks for makin videos on astronomy....😊😊🎉🎉

Indeed the best astrophysics series.....Thank you Professor Dave

I'm soooooo happy that you are on youtube Thanks professor!!!👍👍👍👍👍

I’ve just discovered your channel and surprised by your amazing content.Now I’m starting to learn what I was wondering for years at 1 am thanks😆

One of the best science channels on RU-vid

Driving home and listening to astronomy. I love being a nerd 🤓. Thanks professor Dave.

Thank u sir.. eagerly waiting for this series from a long time. Finally it has started

I have found several lectures on astrophysics, but I wanted to start from your videos because having watched several of your other content, I am inclined to believe that you would make it much easier for me to understand the basics of what I need to know before progressing onto content that goes much deeper into the world of astrophysics. Thank you for what you do.

I wanted to learn the basic knowledge of astronomy,, and that was in the video... Thanks a lot... Sir 💖💝

omg im gonna cry i watched your videos for my chemistry exams and now that i passed with a 94% im watching this video to help me choose my career *initially wanted to study psychology but my family isn't very supportive so im feeling a bit lost rn 😅 PS thank you so much for your videos. without you i wouldn't have understood so many things in chemistry so thank you for saving my life. also i genuinely didn't know you're an all rounder so i truly respect you!

Excited! Still waiting for 'Botany' or 'Pharmacology'!

Please must put proper subtitle as it is. Very difficult to write down every word which u speek

Somebody watching??..🎉🎉🎉

I will love this series

great video

I want to grow up to be a Astrophysicist, but my school doesn't do space stuff so this really helps me. Thanks alot

I am saddens me to see the vast majority of our population with little knowledge of and in some cases ignoring the most profound ,life changing , amazing and awe struck by simply observing . . . . up

Hi I’m 11 years old and I’m very interested in science astronomy, physics, how gravity works and more, so thank you so so much for this👍

I'm 11 years old and I love space! It's so mysterious and so cool! People think I'm too young to think about that.. but I don't care! I wanna be a astronomy teacher!

I absolutely love your content. Would love to chat if possible for a few moments about a potential episode for you.

Hello professor I've learnt a lot from your channel, I am now confident I have the technology to reach the moon, I'm not lying I actually got something.

Every time i see pics of galaxies in the universe i get so mindboggled and think i can't even imagine idea of just how small we really.

Yes yes! I needed this 😍 Thank you professor Dave 🌼

Good information

Thanks alot professor dave! I learned astronomy and astrology in a very early age, i started learning about galaxies at the age of five! And i started learning the planets at the age of 4! Im not that good Basic science, but im really good at very advanced science!

i want a series on quantum mechanics

Hi im 16 and I want to become an astrophysicist but didnt know where to start. Thank u for the videos :DD

Finally after loads of grinding from trigonometry to modern physics... I can proudly say ive made it

Thank you for making astronomy for everybody! You explain it better than my teacher.

thank you.

Thanks for this! Few things are more beautiful then the night sky.

I am 14 years old and I want to learn more about astronomy but my school hasn’t that lesson so this is really helpful thank you . . 😁😁😁

Look at this stellar! Content!

I'm 12 and, his videos helps me a lot

What a guy... you are providing a crucial role in society

Thanks to Proffesor Dave

I have a question I'd very much like an answer to, like most things I'm sure there is a simple explanation I'm unaware of : I know about conservation of momentum, this is somewhat related. The earth is in orbit around the sun traveling at something like 60 or 70 thousand miles an hour through space... If we launch a rocket or a satellite or whatever into space, once it leaves Earth's atmosphere wouldn't the Earth be speeding away and have to constantly catch up?

I love that I found this page❗️❗️❗️

Thanks very much for this series Dave! I'll be using it as a reference when teaching in my astronomy club!

I have always been interested in our universe, and starting here, I have 35 videos in front me. I'm going in.......

Great job👍

¿Any idea how to locate the first aries point from any place you are on earth? Is for the purpose of practicing. Maybe some DIY clinometer gadget, that help me to locate where is the vernal point, and after that, finding a star by it´s declination and AR? Or maybe a simpler method? By the way, i like your tutorials, they are very good!

Hello sir I am from India , I am 14 years old , sir i see regularly your videos you are best , because of you now I am interested in astronomy and I want to join NASA

5:04 My reason for "watching" right now? I can't sleep unless I got some sciency stuff playing as background sound... thanks Professor Dave, and good night!

(Correct me if I am wrong.) Earth is in the goldilocks zone, and it might be one of the many possible reasons why there is life on earth. Earth's SOLAR orbit was in the goldilocks zone, which the goldilocks zone is the distance from the sun. The distance the earth, well orbits from the sun, is just perfect enough to form water. It wouldn't be too cold for the water to freeze, nor too hot to evaporate the water. As well as having-- well, non-poisonous oxygen for us to live in. Thus, forming life. Although there are many articles/reports of living things, organisms, in other planets and moons that may not have edible oxygen. There are also reports of water in other planets and moons, such as Mars, the 4th planet from the sun, and Titan, which is one of Saturn's 100+ moons. Although there are more examples. An AU is an astronomical unit! Which is known to be how far the planet is from the sun, some examples is Venus: 0.7 AU, which totals to 107.72 million km! 1 AU totals to ~149,600,000 million km. And Earth is 147.12 million km, which means Earth is 1 AU away from the sun. And, the AU of the goldilocks zone is between 0.95-1.67 AU, so it means Earth fits in the goldilocks zone perfectly. Thus also becoming the main reason that Earth was able to form life.

This is fun, but I had my hopes up for botany. Did it get placed on the backburner? You can still be the first on youtube to do a comprehensive botany playlist. Go go professor Dave!

lots of kids don't like this, its great that you make it just even a teeny bit more enjoyable for kids

It's probably impossible for us to truly understand the deep connection people had to the mysteries of the sky in the past, before the internet, before television, before we had harnessed electricity to illuminate the darkness. It encompassed their worldview, inspired myths, gave rhythm and regularity to their lives, and allowed them to navigate the world.

I tell all my friends to subscribe..! Greetings from Vienna, thanks for your excellent work...

Dave is the man

This 4 years old thumbnail looks like .... james webb space telescope captured image of space 🙃

I can simplify it. JESUS! I’m joking. I’m not an idiot. 😂 Thank you for this awesome info! I keep it on while I’m on the job and your hard work is noted and appreciated. 😊

This lesson is very useful for me ....tnx.......

The most important thing i have learned from astronomy is never ever let an astronomer name your child

YES

I've been trying to decide whether I should pick astronomy or astrophysics. I really like space and I have this drive where I just wanna know everything I can about everything we don't know. We know so little about space, and I hate it, and I wanna learn everything about it I possibly can in my lifetime. What do you think I should pick? For a bit of background I'm pretty smart I would say and I do great in school. Like, on average, I usually finish the year with 97-98 or higher in everything, sometimes almost all 100s, except art. I hate art. I really fvcking hate art. I'm also above grade level in multiple subjects, like in math im 1 or 2 grades above, and in ELA, im 3 grades above. (These are based on test scores that my teachers showed and told me btw). So, what do you think is better, or what I should pick?

Hi Dave I'm new to your channel and Ive seen lots of interesting things to watch as well as having watched some of them, but I was noticing that most of your videos are short or under 20 mins, where can I go to delve deeper? Do you have another site or channel in which you go into depth about any of all of these subjects?

Is it a new series?☺️

I do have a genuine question - if a star uses up all it's hydrogen then starts using up all it's helium and so on and so forth then explodes at the end of it's life cycle ..... how do other stars form from this exploded sun that has used up all it's hydrogen and helium ?

You are doing great job

Very good. I like your work.

Your awesome professor thanks for the content

great informative video..thanks

James Webb has turned our standard model on its head... There are massive galaxies bigger than Andromeda just after the big bang, that shouldn't be possible according to our current understanding of the universe... there's more, but I'll let your curiosity take you down that path. Humans always convince ourselves that we have the answers, until we don't. Let's not even begin to talk about quantum mechanics... let's just say, only a fool would deny the possibility of creation.

sir can u make a video on RAYLEIGH SCATTERING
