Types of Nebulae - Clouds of Gas and Dust
HTML-код
- Опубликовано: 7 июл 2024
- A nebula is a cloud of gas and dust, but each one has its own unique shape and origin. This video reviews the five different types of nebulae: absorption, emission, reflection, planetary, and supernova remnants. Learn how nebulae are defined and classic examples of each type.

Glad I clicked on this video, superb teaching.
Thank you! I've got some great stuff coming out for 2018. I can't wait to share it!
Very informative! Detailed explanation, by including examples of nebulae mixed with different types!
Thank you! Nebulae are always fun to find in the sky. Hopefully if you get to find any you can figure out which type it is.
This is a great video, very educational. thanks.
luke thank you so much. :)
This video is really helpful, thanks for making it!
I came here to learn and unfortunately I learned. You're a good teacher.
Great explanation of the Nebulae types, clearly described and classified into main groups and sub types👏.
Excellent visuals to support the descriptions.
All your videos are exceptionally educative. Your explanations are precise and methodical.
Such a informative video. I rarely give a thumbs up and this one surely deserves one 👍
I am 44 years old. I firmly believe that i will be able to gaze betalgeuse supernova supposed to occur in the near future. In addition to that i hope i will live till 2062 , to stare at heylis comet , as a person aged 83. I couldnt see it last time 1986 , because i was a small child aged 7.
I'm 25 and I got the same dreams, let's hope they both come true :))
Wow! So Beautifully explained.💫
Thanks!
Amazing. Thank you so much for sharing this!
ty for this!!!
Thank you, explain so well in this video about the nebula.
Quite a good explanation.
Wow!! Thank you
Great video packed with amazing info. Thanks for sharing your sky knowledge🥰❤️
Glad I found your channel!
youre so knowledgeable ❤
👏🏾👏🏾👏🏾 Excellent video
amazing video im doing nebula research for a dnd campaign!
Oooh, how i love this video, crack
This is very good, essential general knowledge 💜🌌
I love nebulae💜🌌
3:39 😂😅
Oh, I follow you. I am a big fan of Orion and his very impressive... sword. 😎💘
Thanks for the informative lecture and also helping locate the various types of nebulae in the sky. V nice and simpified explanation Indeed.
Keep up the good work and in imparting knowledge and creating interest to lay new astronomers.
Awesome
so nice i liked
very good always , why do not do for all 12 signs of constellations , where in sun passes through ecliptic center
The binding energy per nucleon of iron is the peak. In other words fusion between atoms with larger nuclei would take more energy than it would give off to overcome the electrostatic force of repulsion. Interestingly fission with any atoms smaller than Iron would require energy input. So for nuclear reactions that give off energy, Iron is basically the division line for what elements could undergo fusion and fission.
Thank you for your comment. So interesting!
My dad once said " Look at Orion's balls, you'll find Orion Nebula".
Nebula ❤
Can you please make a documentary about what happens to light = electromagnetic radiation when it passes through the not empty interstellar and intergalactic Medium with its various contents like Plasma, Gas, dust, stellar wind, 'cosmic rays' =? proton-streams, neutrinos, gravitational fields, dark matter and ...? effects could be absorption, scattering, polarization, slowing down (like light passing through transparent, dense matter), bending (lensing), stretching or compressing of wave-lenghts (red or blue shifting), loss of energy (transformation from blue to red light, from gamma to radio radiation), ... background questions: if the universe was infinite, could we expect light from an infinite distance arrive here, or would there be a limit distance above which any light would be swallowed up by the interstellar/galactic medium? could the CMB be the faint remnant of radiation sources beyond a certain distance resulting in the radiation being smeared out and weakened to a point shortly before vanishing alltogether? thanx!
Whats the one that looks like when you look at a lava lamp shape? Galaxie ir nebula?
Maybe a planetary nebula. They can have an hourglass shape and have a variety of shapes. Are you referring to the pics on 7:20?
8:44 I think the "eskimo" looks more like the Cowardly Lion from the Wizard of Oz....🤏🤷♂️🤣🦁
Also, if iron is the last element known in a star, how do we have the periodic table? I never understood that.
Great question...anything larger than iron was created in a supernova event. That's how larger elements are made.
@@learnthesky That makes sense as to why there's so little of just about every element. However, it doesn't explain how the *process works*, if you get me. Like, is more fusion happening during the explosion?
Latin suffix "lae" is pronounced lä (lay)... I just googled to double check...so nebulae would be "neb-you-lay"... you got it wrong at 0:45 when saying how to say it, but said it correctly twice at 3:02 then wrong again at 3:57... 😆
I think I see an alian in the middle spot on the trifid nebula 😕
Vulpecula is in the northern hemisphere
Excuse me, what kind of software are you using to edit your videos?
I use iMovie. It's not as sophisticated as other types of film editing software, but that's why I like it.
Our Sun can barely create 1 noble gases without Hydrogen.
