8:57 Watching light traveling through space.... Waaaay too cool!

[eswing]

You are an amazing science storyteller. You should be proud of your work.

The animations and simulations in this video are stunning. I kept rewinding them over and over again because I was so "star" struck.

[jeromedufour]

I have watched several videos about stars over the years but this one is the most informative imo.
Great job there!

[carlchristensen]

I did learn something about stars today, thank you.

[BrewCityGillz]

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.
Those waves of light moving away give a good idea of size and I find it mind boggling, amazing.
Thanks.

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.

24 brown dwarfs were insulted by the video calling them "failed stars".

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. 🥰

[migram]

Fantastic explanation!! Those light echoes are beautiful! 😍

@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?

[TheShollen]

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😃.

[bilalawan]

Yes please make a video on Brown Dwarfs

[alexhatfield]

Beautiful presentation, graphics and background music, Alex

[thomasgagliardi]

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?

[MADDLADO]

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 💖

[panchu]

Amazing video! Made the day worthwhile. Please upload something on Pulsars, Cepheid variables and hypervelocity stars.

[gaspipe]

What a brilliant presentation as always....Thanks Alex
