They are often star-forming regions.
Stars form when gas, dust, and other materials out in space begin to gather together, forming larger and denser masses, which collect until there are huge clumps of dust and gas. The clumps are called protostars, and as gravity acts on the material, compressing it further, it heats up to over 10,000,000 degrees Kelvin. That is the point were hydrogen fusion can begin.
Hence, a star.
There are two sources of nebulae: exploding stars and material from the original formation of the universe.
(Rosette Nebula SOURCE)
There are also five major types. Emission, Reflection, Dark, Planetary, and Supernovae Remnants. (One thing I love about astrophysics--they keep the names in plain English.)
Emission:
(Orion Nebula SOURCE)
Reflection:
(NGC 1977 SOURCE)
Dark:
(Keyhole Nebula SOURCE)
Planetary:
(NGC 2818 SOURCE)
Supernovae remnants:

Have you ever seen a nebula? (As in, not just a picture but through a telescope or with your own eyes?)

Oh my goodness, what GORGEOUS photos. Love these. Thanks for sharing! They are amazing. :)
LOVE the pictures! And to answer your question - no, I have never. But I'd really like to. Stars = rocks! (Or the fiery kind...)
This is something out of a dream. Amazing. I love the supernovae one.
Aren't they just beautiful?!?! To think that these depict such cathartic violence as stars exploding and being created! Wonderful! Take care

Brilliant photos. Like art.
These pictures are just stunning - I didn't realise you could see them with your own eyes (pretty sure I haven't though - how could you miss that ??) I like their names too ...
Thanks for the science - and the photos :-)
All best, Karla
These are truly amazing pictures that make me realize how small I really am. Your blog is always so interesting.
Oh boy I was looking forward to today's post and I wasn't disappointed. I've never even looked for a nebula. Have you seen one - bet you have! Those wonderful photos look like something off Flamepaint.
You are a clever girl :)
Amazing photos! You would really enjoy the Star Walk app on my iPad. Photos, locations, details, etc.
Nice!
Stunning pics...
Thanks for sharing.
I love astronamy and these pictures are amazing. I thought I was already following you but I wasn't so I corrected that today.
I really enjoy your blog.

amazing pics. Sadly, I have not seen a nebula through a telescope - in fact, I don't think I've ever even looked through a telescope.
Oh how stunning. I love the first one. No, I have never seen one with my own eyes, but I would love to!
I love nebulas. They are so beautiful.
I didn't know there was an Eagle nebula, wow!!!!
You picked some gorgeous examples. These are some of my favorite things to look at on the NASA website....
Beautiful post :)
Happy weekend!
Awesome pictures! I love nebulae.
Nebulas are so gorgeous. I remember I went to a science museum and they had a special exhibit on space. They darkened all the rooms and put up huge backlit photos of nebulars and other amazing sights found in space. My favourite pics were the nebulas.
My screensaver is of a nebula after the supernova of a star. I think those are the most beautiful. Awesome post!
Wow!!
Thanks for reminding me the beauty of Nebulla,
I was interested in astronomy as a child!!
with warm regards

Ooooh! I love, love, LOVE these pictures! Yes, I saw some real nebulae through telescopes when I took an Astronomy for Teachers class one summer. That was truly awesome too, though they weren't as colorful as these pictures!
Carla
That was wonderful! Can you imagine the power in all of that?
Increbible. I love these.
Gorgeous. Such huge things going on around us, and we don't notice.
Oooh, I LOVE astronomy! I can't say that I have seen one, but I know that I've seen the Milky Way! Thanks for the beautiful post!

wow the photos are stunning. :) No I havent seen a nebula.
AMAZING photographs! Thanks for sharing. :-)
Love the pictures. Space is so intriguing.

N. R. Williams, The Treasures of Carmelidrium.
Amazing photos.
I'm partial to the 1977 one.
And the last one looks like the loch ness Monster, don't you think?
So beautiful! And the word Nebula is fun to say too. I love the colors, though I think I read somewhere that the colors are added when they are NASA pictures.
Wouldn't that be an interesting job, picking pictures to release and adding the filers to make those colors?
Wonderful photos! Thanks.
I wish I had a telescope that was worth a "you know what".
I am truly amazed by what is out there, and I wish I could get a closer look.

No, I haven't been so privileged. Just seen amazing pictures in national Geographic magazine, amongst others.
You have a very nice blog :)

Fantastic what hangs out in the universe, just a night's dream away...
While I can safely count myself as one of the many that has not seen such an amazing sight with my own eyes or through a telescope, I can most assuredly tell you that I have, in my dreams, encountered a few.
I know that doesn't count in the real world...but then I always say "what's a real world anyway"!
As always - an incredible post.
Jenny
So inspiring, thanks, Golden Eagle.
Carol: You're very welcome! :)
Cruella: You can see the Orion Nebula if you look at Orion's Belt--it's between two of the three stars.
Elena: I do, too. :)
Old Kitty: It's amazing that they're born from and create stars, isn't it?
L.G.: They are a lot like art!
Karla: Nebulae aren't particularly obvious--they're a lot like stars here on Earth. :P
You're welcome!
Josh: I remember one YouTube comment on a video about the universe that said something along the lines of "I officially feel like a speck of dust". LOL.
Thank you!
Donna: Glad you liked them!
Lauracea: Yes, I have--the Orion Nebula, actually. My mom and I went to an observatory and they had several telescopes set up. :D
Alex: It's sounds awesome!
Have you ever tried out Google Earth? They have all kinds of links and you can explore the night sky with it.
Siv: The universe is just amazing. :)
Michael: You're very welcome!
Pamela: Thank you for following! I'm so glad you enjoy my blog. :) I hope my A-Z posts continue to keep your interest.
Mshatch: *gasp* *choke*
Just kidding. ;) But you should do it sometime!
Emily: It's nothing like the images that come from powerful telescopes, but there is something amazing in being able to see a far-away object yourself. :)
Holly: They are. :)
The Words Crafter: Yup. And you can bet it's one of my favorites!
Have you seen their Image of the Day? NASA always posts some fascinating things there . . . I've got the gadget on the bottom of my site.
Thank you!
I hope you had a great one!
Liz: I do, too. :D
Lynda: It sounds like a great exhibit! I've never been to something like that; most of what I've seen has been online or (a few times) through a telescope.
Alleged: Nebulae are just gorgeous things. :)
Thank you!
Abhishek: Anytime! :D
Carla: I'm so glad you enjoyed the pictures!
Awesome. :)
Susan: It's amazingly hard to grasp--all that energy, and light, and matter.
Charles: Aren't they?
Lishacauthen: Exactly. The universe is so huge--and Earth, comparatively, is less than a speck of dust.
Elizabeth: The Milky Way is awesome. :)
You're welcome!
Niki: Glad you liked them!
Cally: You're very welcome! :)
Nancy: I'm glad you enjoyed them!
It is. So much to discover!
Theresa: LOL. It does look a bit like the Loch Ness Monster, doesn't it? It's called the Horsehead Nebula, interestingly enough--I actually just finished a novel this afternoon by Isaac Asimov (The Stars, Like Dust that focused on it.)
Cindy: Really?! I thought the color were from infrared/ultraviolet/microwave frequencies. Wow.
It would be!
Bob: You're welcome!
Thanks for coming by my blog. :)
Tomara: I wish I did, too. Although there is a telescope in the back room--I dunno if it still works after being moved and jostled around so much. :P
Me, too!
Duncan: National Geographic is certainly worth the look. :D They've got some absolutely amazing pictures . . .
Thank you!
Pearson: With all the mystical-looking images, a dream doesn't seem very far off. And you can go anywhere when you're sleeping. :)
Thanks!
Deborah: You're very welcome!
I did a mini-version post on nebulas for "N". I love the history you added about their origins, creation - and all the pictures. Just amazing!
Wow, what fantastic pictures! The Eagle Nebula is amazing.
Fascinating stuff and such wonderful pictures. I've seen a few through small telescopes - M42 for instance - but of course you need something rather grander to take pictures like those!
I've always loved our studies on space. The sky is so beautiful and I have spent many nights watching the rising of different moons, (Harvest moon, blue moon, lunar eclipses) and star gazing and of course, meteor showers.
The pictures you have are beautiful.
Really enjoy your blog and the information you post.
:) Thanks! Have a terrific day!!
I love your blog. It is amazing and so are you. I have come to award you with the Stylish Blog Award which you can pick up on my blog. Have fun and follow the rules which I have posted there.
