Great vid to complement the one you did on interesting stars. RS-Puppis has been my favorite star since and seeing it again here was delightful. Those waves of light moving away give a good idea of size and I find it mind boggling, amazing. Thanks.
Thank you for renewing my interest in space. It never disappeared, but it did wane for awhile. Keep up the amazing videos. You put a lot of time and energy into them and it shows. 🥰
You know it is very difficult to explain scientific facts to general public ( mostly it becomes boring 😆😜 ), but Alex you do it flawlessly. its a gift you have it 😊. keep it up and you will reach new levels of yourself😃.
These videos are absolutely fascinating, and some of the best quality shows I've ever seen. To you who produces these, thank you for such wonderful products 💖
@8:56 I had to pause: my jaw dropped, literally. Im a big Astronomy fan, but I had never seen something like that. Thank you for the video. Whats the radius of the dust structure?
@Astrum You are a bright man, absolutely brilliant, educating & enthralling!! When I can't sleep, when I wonder how the universe works, when I'm distraught or distracted, all I need is a video or two to feel like I am part of this cosmic wonder! After all, We Are Stardust! Thank you for your genius, creating this channel was the greatest part of my RUclips discovery!!
Love your work mate. Seeing improvements on your presentation both visually and verbally. Great work bud. Congrats on the little one! Good luck with parenthood and with the channel. Much love.
I have justbstumbled your 'Jovian Moons' and this video... they were amazing! Lately, I am wondering if you could shed some light about what scientists' think about 'Dark Matter' too...
When viewed from near a city, all the stars do look alike. In my hikes to some fairly remote areas devoid of most of the light pollution, I sometimes stretch out under the stars and that's when you really notice the differences. The night sky from an area like that is something everyone should see! Alex- your videos continue to get better in quality. I only wish I improved that much with age!
Now I wonder, what was day on Earth like when Sun was only 70% bright (if the Earth was around at all, back then!) :D Is our Sun getting brighter, or larger - or which one of these 2 will happen faster? Anyway, poor Mercury... Thank you for another excellent video!!!
DeeARTIST Jewelry ...it was 70%... but I thought the same thing. Not a stretch to think our planet was much colder, dare I say, in a prolonged ice age.... Pretty hard to determine what phase our Sun is in... I'm sure science is striving to answer that very question, however, no matter what their conclusion, it is likely they'd be wrong. Time, in an astronomical sense, is measured in millions of years... It would be like predicting that next week it's going to be colder outside, by extrapolating data, from only one second of our current temperature! Just not possible in my opinion... Data collected on the Sun, for a hundred years, is but a blip in time...
Unless it has a sufficiently massive companion that it will eventually collide with on the timescale of trillions to quadrillions of years, it's highly unlikely that any brown dwarfs will ever become stars.
Would be incredible to one day spot the death of a red dwarf. That's one of the questions we definitely would love to see answered. They live a LONG time though,
Truly fascinating, and I always learn more watching your productions. You’ve been busy these past few weeks! Looking forward to what’s next. Thank you!
>Nebula are the most dense regions Interesting how nebula means almost the opposite in everyday parlance, something like "less tangible" or not well defined.
I don't know about rainbows, but I do know that the Martian sky is yellowish red, and Martian sunsets are blue! Its atmosphere is 95% carbon dioxide, rather than 78% nitrogen/21% oxygen.
@@RawSpaceVideos Whats up Raw. Yeah, i was wondering how different atmospheres would change the way light refracts. Or even a completely different spectrum from a different star.I say "rainbow" but i guess it would depend on what is refracting the light. 🤔Hmm, well I have no choice but to travel to these planets myself!
@@TestTubeBabySpy With Mars, there are a couple of challenges. The low atmospheric pressure results in almost all Martian water being either frozen, or sublimed into vapor. Rainbows require refraction through material dense enough to alter the different wavelengths of light to different degrees (i.e., droplets or crystals). I suppose atmospheric ice crystals could cause a rainbow, though there is precious little water in the Martian atmosphere to freeze. The second challenge is the makeup of the Martian atmosphere, which is almost all carbon dioxide - which sublimes, rather than melts. There can be no CO2 droplets, and the CO2 gas is not going to form a rainbow.
Hello Alex 😊 , as always your videos are the best on this subject ( astronomy ) !!! Thank - you so much for taking what is a much more complicated topic and making it simple, easy and enjoyable for those like myself to understand 😊👍👍👍💖 .
Alex, awesome presentation. I wanted to ask, you know how scientists are able to make measurements of things like the mass of a galaxy or talk about all the matter they can see not adding up to what should they see? Are they including the matter in the seemingly empty space? You mentioned the amount of stuff in the imperfect vacuum and interstellar medium. Is there a lot of heavy atoms produced in the fusion of stars that you can’t see in a telescope? I ask the universe...
Green Rabbid Rabbit ,thanks. If yes, how do they include that stuff in their adding up how much mass there is in a large area like a galaxy? I am going to find something good to read about it, but maybe you can help too? Or recommend a book? When they say gas and dust, what is the dust usually made up of? Anyway, thanks for the “yes”.
You are an amazing science storyteller. You should be proud of your work.
Agreed
I bet he is very proud
Im damn sure proud of him!! Much love Astrum and ty for all your hard work and dumbing things down for folks like me :)
The animations and simulations in this video are stunning. I kept rewinding them over and over again because I was so "star" struck.
Nektu WTF SAME
The puns
8:57 Watching light traveling through space.... Waaaay too cool!
actual speed of light filmed
I have watched several videos about stars over the years but this one is the most informative imo.
Great job there!
I did learn something about stars today, thank you.
Excellent examples and easy to understand explanation. Not that I’d expect anything less from your videos. Keep up the great work! ⭐️☀️💫
Great vid to complement the one you did on interesting stars. RS-Puppis has been my favorite star since and seeing it again here was delightful.

Top quality content 👍
Fascinating stuff Astrum. Thank you!
Thank you for renewing my interest in space. It never disappeared, but it did wane for awhile. Keep up the amazing videos. You put a lot of time and energy into them and it shows. 🥰
Mine did too - until I discovered this channel. By far the best factual space docs out there.... (excuse the pun) :D
It was the best video about how starts are born. I have seen many video trying to show the concept. But so far this is the best well explained.
Fantastic explanation!! Those light echoes are beautiful! 😍
You know it is very difficult to explain scientific facts to general public ( mostly it becomes boring 😆😜 ), but Alex you do it flawlessly. its a gift you have it 😊. keep it up and you will reach new levels of yourself😃.
you sound like some local chinese fortune cookie
Yes please make a video on Brown Dwarfs
24 brown dwarfs were insulted by the video calling them "failed stars".
Or 'dwarves' even. And, they aren't that dim!
PC... Brown little stars.
@@ADEehrh mass challenged
Brown drafs are the failed sons of star formation. Dad is not proud!
Maybe they were too dim to understand?
I rarely ever comment but you are just great...from one astro lover to another...thank you. And god bless...I don't know....Titan?
These videos are absolutely fascinating, and some of the best quality shows I've ever seen.
To you who produces these, thank you for such wonderful products 💖
@8:56 I had to pause: my jaw dropped, literally. Im a big Astronomy fan, but I had never seen something like that. Thank you for the video. Whats the radius of the dust structure?
The radius looks to fit 8 waves and the pulse is 40 days so i estimate 8*40 = 320 Lightdays.
What a brilliant presentation as always....Thanks Alex
Great Work, Great video, very educational and dreamy, nice touch with the music.
That light echo might be the coolest astronomical thing I've seen for years
Amazing video! Made the day worthwhile. Please upload something on Pulsars, Cepheid variables and hypervelocity stars.
@Stellvia Heonheim Not pathetic, mundane maybe. What about yours?
@Stellvia Heonheim Life is generous. What about you?
Seeing the light travel through the cloud was really amazing to see!
Your best episode yet!! Really opens the mind to the universe
@Astrum

Beautiful presentation, graphics and background music, Alex
Stellerdrone
Brilliant video mate!
Very very nice explanation! Keep these vids coming!
Yaaaay, black holes and super XXXL stars! That's an episode I look forward to a lot! Thanks!
You naughty one 😂😂🙈
Excellent presentation!!
Love your work mate. Seeing improvements on your presentation both visually and verbally. Great work bud.
Congrats on the little one! Good luck with parenthood and with the channel. Much love.
Thank you for this explanation. If you take suggestions, perhaps you could include the timeline of the different stages you talk about.
I've loved Astronomy and the expansion of the Mind since early childhood. Love your videos. Keep up the Great work!
You, Anton Petrov and Scott Manley are my go to everything about space and cosmos. Keep it up! 👍
This is right up there with the best. Great script and graphics.
I love the quick wrapup in the end. More science Channels should do this.
I'd love to hear more about the instability strip!
Lots of strip shows already on the internet
Absolutely love your videos, thanks a million for your fascinating content 👍🏻👍🏻👍🏻
Fantastic video one of my favorites thank you Alex
Excellent presentation. Thanks.
Fascinating and well explained
So this is maybe the best video on stars I have ever seen. Thank you.
Thanks, Alex! ✨
I simply just love your videos. So clear, smart and educational in nature that it feels like home.
Alex McColgan. David Attenborough of the stars. Love the videos! Thanks, Alex!
I agree!
I have justbstumbled your 'Jovian Moons' and this video... they were amazing!
Lately, I am wondering if you could shed some light about what scientists' think about 'Dark Matter' too...
Luvin this channel atm. So chill and so interesting.
I guess, "atm" stands for "ass to mouth" .
You describe space veey well. Keep up.
So do stars actually ignite at some moment in time? Have we been lucky enough to capture the moment in all our observations?
Yeah it happens when careless interstellar truckers throw a cig out the spaceship window.
Yes. Starburst.
Please make another video about the brown dwarfs🙏🏻, I learned a lot here and a bunch of my questions have been answered here!!! Thank you so much...
Alex, bagging for continuation of series dedicated to stars !
Very well done
Fascinating 👍😇
those light ripples are so cool
8:56 WOW!! Actual speed of light filmed.

Very informative video after some time. Keep it going bro 😍
Great video, very informative
I really love your video.
Please do a full video on brown dwarfs they don't get talked about often enough
Just a Great learning video!!!!
8:58 Wow
gorgeous animation
Yes please, a video about brown dwarves. Meanwhile, can a brown dwarf still eventually become a star? Thanks, and btw I like your music.
Unless it has a sufficiently massive companion that it will eventually collide with on the timescale of trillions to quadrillions of years, it's highly unlikely that any brown dwarfs will ever become stars.
Great video.
Brilliant video! I found the part about "light echoes" fascinating. Or should I say illuminating?
i am your new subscriber from India❤️🙏🏻
amazing information
I want to put the music you use for your videos into my space engine playlist.
Id love a dwarf star video 👍
@@greenbanana311 lol 😄
Badass bro ty!
Would be incredible to one day spot the death of a red dwarf. That's one of the questions we definitely would love to see answered. They live a LONG time though,
Hey, please do an episode of astrum answers as to why are red dwarfs next to eternity.
Truly fascinating, and I always learn more watching your productions. You’ve been busy these past few weeks! Looking forward to what’s next. Thank you!
Stellardrone
I love your channel so so much !!!!!!
I am waiting for mooree :))
You are the best Alex, love astrum SO MUCH
Who dislike this great video???
Those who believe Space is fake.
Weebs
>Nebula are the most dense regions
Interesting how nebula means almost the opposite in everyday parlance, something like "less tangible" or not well defined.
It tells you about stars & planets on information & how they show the transformation of the universe .
Awesome!
Great video! Thank you so much Alex!
What would "rainbows" Look like on other planets with different atmospheres, or even a different star?
I don't know about rainbows, but I do know that the Martian sky is yellowish red, and Martian sunsets are blue! Its atmosphere is 95% carbon dioxide, rather than 78% nitrogen/21% oxygen.

Do a video on the newly found Teegarden exoplanets if you have time I know you’re busy.
Some stars are white,
Some stars are blue,
Most poems rhyme,
This one don't.
i love this channel
Hello Alex, gret video as usual. Congratulations on the birth of your little one :)
Awesome.
Like it 😍😍😍
When comes the conclusion of this series? Stars are so interesting!
Hello Alex 😊 , as always your videos are the best on this subject ( astronomy ) !!! Thank - you so much for taking what is a much more complicated topic and making it simple, easy and enjoyable for those like myself to understand 😊👍👍👍💖 .
You talk about Brown dwarfs and main sequence stars but what about the Red Dwarf Stars what's the cutoff point for them, I'm just curious about that
Red dwarves are the smallest and most common main sequence star, formed from brown dwarves.
Good example
excellent video, thank you.
many thanks Bro, very educative video...God bless you
Great video! New sub here
