Types of Nebulae: Stellar Nurseries and Star Remnants

The scale of size just amazes me. Little wisps on the edges larger than out solar system. It's just incredible.

I love it when Prof Dave does astronomy! Prof Dave kick started my love of science and I am forever grateful!! Love from Australia 🇦🇺

Your content is some of my favorite stuff to watch. I've always enjoyed learning, but my (long undiagnosed) dyslexia made a real impedance for me all through grade school. I can't thank you enough for your channel. As busy as you are, I really hope you see this.

Thank you professor Dave, as always, excellent work - i've learned so much since ive joined your channel and i especially enjoy your videos about Astrophysics and Cosmology, my favourites - instant clicks. Keep up the great job. Regards from Prague

Thank you professor Dave for enlightening us with knowledge. It’s impossible to comprehend the scale of the universe in my mind. So amazing

Always great work from this man

I'm just here to read proff. Daves reply to flat earthers/science deniers in the commentary section.

Hello Professor Dave. Thank you for all of the great content. I am a well educated man and get alot out of your lectures. I finished my college education prior to the 1990's. Like today, I was forced to accept that there was alot that we did not yet know about science. Since that time we have defined dark matter and Hubble has given us "heavenly" views of the cosmos. I am a retired disabled Vet and I enjoy spending my time learning and helping tutor Children in mathematics as I am not married and have no children. I was a debate team captain through highschool and college. I was, as I mentioned very impressed with your domination of that jailbird clown. My question came to me when I was on the internet. I have never been taught anything about what some flat earthers call the "Fervament."? I may not even have the correct spelling. Also, what is " luminescent ether" ? I have never heard you even address these. Simply put, are these words just balderdash, nonsense, or is there a new branch of cosmology that I need to look at? Thanks again. I dont want a bunch of trolls hounding me, so I came here to ask you. Thank you for your time.

Thank you, Dave! Finally I get what scientist referring to with "gas and dust". Yes, guess it's one google search away to find out but I haven't remember to do it, lol.

You are great Sir!!!! Hats off 👏👏👏

Prof Dave? I have a request. Could you please make a video on string theory? I really want to understand that topic and I know that you can definitely explain it very lucidly.

Dave: “...Pillars of Creation”. Kent: “Ah-hah!”

Love your work.

To be honest, professor Dave's voice started to sound like hawking as he was explaining all of this.

It would be really cool to some day have a visualization of how big structures like the pillars of creation have evolved over time

There are at least two known stars, both approximately one hundred light years away, that are siblings to our sun and formed in the same nebula and roughly the same age.

Pause at 7:11 and you will know what this nebula was supposed to be called instead of Gomez's Hamburger.

They actually have low particle density compared our atmosphere. It's just their sheer scale from a great distance in empty space that makes then look thick.

Quality Information 👌👌
