Dark+Nebulas

This website goes more in depth into the chemical make up of the Nebulae and what causes it to form. It also talks about the formation of stars that takes place in the inner regions of the dark nebulae.

__Introduction:__
===A dark nebula is "a cloud of interstellar gas and dust that is sufficiently dense to obscure partially or completely the light from stars and other objects lying behind it and sufficiently large and suitably located to produce a noticeable effect." (//The Facts on File Dictionary of Astronomy**)** //=== Links:

** I found this website to be very interesting, because it talks about what dark nebulae, how they are formed and how they are made up of different type of gases and clouds. This information which was written by Kelly Whitt, also states that dark nebulae are located in the milky way galaxy and other distant galaxies far away. It also talks about some of the most famous dark nebulae (Horsehead Nebulae for example). So if you’re looking for a website with lots of information about dark nebulas, then I highly recommend this website to you. **

__[|http://astro.nineplanets.org/twn/type]____[|s.html]__   **This website has information not only on Dark Nebulae but on all the different types of Nebulae as well and where they can be found. They have a few pictures to accompany the information so it gives you a general idea of the variety dust clouds in our solar system. (Bill Arnett)**

** I chose this website because it has some good information about dark nebulae. When I was reading I found out that it is hard to find dark nebula even using a telescope. I also read that a dark nebula was once thought to be holes in the milky way, but later it was discovered to be just dust clouds blocking the view of other stars. (Kathy Machin) **

DARK NEBULAS: Nebulas are interstellar clouds, groups of dust and gas in our galaxy. Some nebulas are regions where new stars are being formed and some are remains of dead or dying stars. There are many different types of nebula but this page mainly links you with dark nebulas. I have posted pictures for those of you who do not know what a dark nebula looks like. Some information regarding them is that they are so dense that they obscure or absorb the light coming from stars or bright nebulas behind them. I hope this page can be useful to you.

**<span style="background-color: #ffffff; color: #000000; display: block; font-family: Arial,Helvetica,sans-serif; font-size: 120%; text-align: left;">I find that this site could be somewhat important although there isn't that great of a description of what a dark nebula is. The site provides a map of many of the dark nebula regions within 2000 light years plotted on the galactic plane, a list of the major dark nebula regions with their coordinates, as well as a diagram of the major molecular clouds found along The Milky Way. One of the most interesting things the site offers is a list of the famous dark nebulae their distance in light years and coordinates. These nebulae are supposed to be easily seen with a small telescope. Because of the graphs, maps, and diagrams this page is a little hard to understand and would be suited best for adults rather than children. **

The magnificent Horsehead Nebula, which is very famous.

It is an up to date article as of the year 2009. The site is great for people of all ages and allows you to ask questions, have a discussion, or answer any other questions that have been asked. There is a detailed description of what a dark nebula is and many other facts regarding dark nebulae. If throughout your reading of the article you come across a word which is not widely known you can click on that word and the site will take you to a new page explaining what it is to you. The site is very easy to read, and easy to navigate through.

On this page are pictures of not only dark nebulae but the other forms of nebula which are emission, planetary, and reflection as well as globular clusters. It is very neat to see the differences between them and how we can distinguish one from the other. The pictures available on this site are good for all age groups. The accuracy is wonderful because all pictures include a detail of where they came from.

Snake Nebula can be seen in this picture.

<span style="background-color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-weight: normal; text-align: left;">This website has a just one page on Dark Nebulae but the Author of the website, Donald R. Hersh, after describing what a dark nebula is and giving some background information on it he also gives you a photograph of one. He talks about the photo but whats unique is he talks about how the photo was taken and with what kind of camera and what equipment was used. He shares all his details and makes his website seem very reliable. You could also navigate away from that page to explore different Nebulae and galaxies and he shares the photo information on all the pages. I found that to be quite interesting. <span style="background-color: #ffffff; display: block; font-family: Arial,Helvetica,sans-serif; font-weight: normal; text-align: center;"> <span style="background-color: #ffffff; display: block; font-family: Arial,Helvetica,sans-serif; font-weight: normal; text-align: center;">

The site makes it very easy to understand because if you don't know a word you can simply just click on it and it will take you to another page with a definition. There are few pictures to help understand and the site is very simple. It doesn't get overwhelming.

<span style="background-color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-weight: normal; text-align: left;">Bernhard Hubl put together this website full of pictures varying from Emission, Dark and Reflection Nebulae. He did a wonderful job. He has many pictures put on here and each is of great quality. When you click on the photo you get a complete list of details. He includes whether the photo has or can state the object type, size, magnitude, constellation, distance and the photo quality from the quality as in exposure and etc. He really goes into detail with each photo. It is extremely easy to navigate around as well you just click on a picture or click on the navigation bar on the left. I really recommend checking out this website.
